8th November. Corrected proofs on line. E.M.Garcia-Ayala, L.Silvestroni, J.Yus, B.Ferrari, J.Y.Pastor and A.J.Sanchez-Herencia "Colloidal processing and sintering of WC-based ceramics with low Ni content as sintering aid", J. Eur. Ceram. Soc, on-line (2020). DOI: 10.1016/j.jeurceramsoc.2020.10.038

By colloidal processing 3 wt% of Ni has been highly dispersed into a WC matrix to develop a cermet with very low metallic content. Rheological studies allowed a high dispersion of the nickel in the final composite powders. Sintering studies by Hot-Pressing route (HP) proved the great benefices of Ni as a sintering aid, decreasing the maximum temperature necessary to achieve full densification, from 1900 to 1450 °C and dwell times from 20 to 7 minutes. Among all the materials obtained, the best results in terms of density, microstructure and properties were obtained for WC-nNi, which achieved hardness of 14.8 GPa and toughness comparable to conventional cermets with much higher content of metallic phase.

29th June. New Paper on line. Z. Gonzalez, J. Yus, Y.Bravo, A.J. Sanchez-Herencia, A.Rodríguez, J. Dewalque, L. Manceriu, C. Henrist and B. Ferrari, "Heteroacoagulation of lignocellulose fibers-based biotemplates and functionalized TiO2 nanoparticles to tailor film microstructures", Cellulose, (2020). DOI: 10.1007/s10570-020-03297-1

This paper describes the preparation of LCNF-TiO2 core-shell nanostructures by heterocoagulation methodology, confirming the formation of a peptide bond between the amine group of PEI, the stabilizer used to disperse TiO2 NPs, and the carboxyl groups of the LCNF. Moreover, the manuscript is also claiming the exploitation of these LCNF as bio-templates, offering an interesting strategy to revalorize agricultural wastes with relevant applications. An example of this development is the design of porous TiO2-based photoanodes with an efficiency value around 6%. The processing method allows to decrease the operation time as well as the thickness of the TiO2 coating from 12.6 µm to 8.7 µm to deliver similar photoefficiency.

Colloidal approach during the manufacturing process allows to modify the component surfaces as well as final structural properties of the synthetized materials. The photovoltaic parameters were quite comparable to the photoanodes fabricated from others commercial celluloses fibers (not from bioresources). The methodology could be applied in other than conventional DSSCs, related energy fields (harvesting, storage, etc...)

On the other hand the project POROMET "Metodos alternativos de fabricación de placas metálicas porosas"/"Alternative methods for the fabrication of porous metallic plates" is a part of the call "Retos Colaboración" which requires the participation of companies and has a high industrial compromise. (reference:RTC2019-007426-3; period: 3 years; budget: 170.545 €)

Both of the projects are cofunded by the European Community throuhg the FEDER program.

25th May. Back to the lab. Attending to all the safety indications, our team is slowly resuming the lab activities. There are a lot of pending and delayed work and a bunch of ideas that have arisen during the lockdown. Even though a great part of the work will still be done remotely, we are very happy to announce that we'll be reopening the doors of the lab.

30th March. Supporting the Healthcare Workers.

8th March. New Paper online. S. Behnam Abdollahi, J. Nourmohammadi, F. Sadat Mahdavi, J. Yus, A. Ferrandez-Montero, A. J. Sanchez-Herencia, Z. Gonzalez, B. Ferrari, "Effect of SrR delivery in the biomarkers of bone regeneration during the in vitro degradation of HNT/GN coatings prepared by EPD",Colloids Surf. B., 190, 110944 (2020) DOI://10.1016/j.colsurfb.2020.110944

The incorporation of Halloysite nanotubes (HNT) as nanocarriers of SrR, into gelatine (GN) coatings, tailors the release of this anabolic bone-forming and anti-catabolic agent to stimulate bone growth. In fact, as-prepared GN/HNT-SrR coatings release 100 % SrR in phosphate buffered saline (PBS) within 21 days, and cellular studies of the nanocomposite coatings (MTT, Alkaline Phosphatase activity (ALP) and Calcium deposition assay) confirm the valuable bio-performance of these composite coatings to enhanced bone regeneration. In the present manuscript, suspensions with HNT/GN weight ratio of 0.5 are formulated to coat AISI 316 L stainless steel foils by Electrophoretic Deposition (EPD). Zeta potential determination is used to stablish the drug loading (HNT-SrR) by electrostatic interaction, as well as to optimize the dispersion of bare HNT and HNT SrR-loaded in a GN aqueous solution. Polyethilenimnine (PEI) is used as stabilizer to buffer the suspension media, assure cargo-drug dispersion and sequential release, while the thermal gelling of the suspension controls and step up the coating formation during EPD.

20th February. New Paper online. A. Ferrandez-Montero, M. Lieblich, R. Benavente, J. L. González-Carrasco and B. Ferrari, "Study of the matrix-filler interface in PLA/Mg composites manufactured by Material Extrusion using a colloidal feedstock", Addit. Manuf. on line (2020) DOI://10.1016/j.addma.2020.101142

The aim of this paper is to investigate the evolution of a matrix-filler interface during the processing of novel composites formed by a matrix of polylactic acid (PLA) and Mg particles, when they are manufactured by Materials Extrusion. To improve the Mg dispersion, the surfaces of the particles were previously modified by the adsorption of dispersants. The physical and mechanical characterization of PLA/Mg composites show that the Mg surface modification is the key to its successful dispersion due to the formation of ionic interactions between the dispersants and the matrix. Moreover, a PEI-PLA covalent bond appeared in the printed scaffolds as a consequence of the temperature applied (165 °C) during extrusion and printing. Consequently, the matrix-filler strengthened interface improved the extrusion process and permits the printing of 3D customized pieces. At the same time, particle agglomeration and the nozzle blocking is prevented.


20th February. ACERS Spanish Chapter meeting. Our colleages A.J. Sanchez-Herencia and B. Ferrari has attended the first meeting of the ACERS Spanish Chapter. Both of them are members of the American Ceramic Society (ACERS) and has personally supported the creation of the chapter. the meeting was hosted by the President of the Spanish Chapter, Arnaldo Moreno at the Instituto de Tecnología Cerámica in Castellón.

15th February. New Paper published. A. Ferrandez-Montero, M. Lieblich, R. Benavente, J. L. González-Carrasco and B. Ferrari, "New approach to improve polymer-Mg interface in biodegradable PLA/Mg composites through particle surface modification", Surf. Coat. Tech. 383,125285 (2020) DOI:/10.1016/j.surfcoat.2019.125285.

The paper successfully proposes PLA/Mg composites as biodegradable and fully bioabsorbable materials for bone repair. It claims the benefits of Mg particles modification throughout the adsorption of surface modifiers in the in vitro biodegradation behavior of PLA/Mg composites. Additionally, the mixture of PLA with Mg particles in a colloidal suspension replaces the thermal-melting extrusion mixing, preventing the drawbacks associated to the thermal degradation of the polymer during processing. To fulfill this requirement it is necessary to improve the interaction particle-liquid medium for the hydrophilic surface of Mg particles and the organic solvent of PLA, which will provide the maximum dispersion of the Mg in the composite. In this sense, surfaces of Mg particles were modified by the adsorption of two different stabilizers, a surfactant as cetyltrimethylammonium bromide (CTAB) and a polyelectrolyte as polyethylenimine (PEI).

16th January. New Paper online. J. Yus, B. Ferrari, A.J. Sanchez-Herencia and Z. Gonzalez, "Understanding the effects of different microstructural contributions in the electrochemical response of nickel-based semiconductor electrodes with 3D hierarchical networks shapes"  Electrochim. Acta. 335, 135629, (2020). DOI:10.1016/j.electacta.2020.135629

This paper deals with the enhancement of the electrochemical performance in energy storage devices by controlling microstructural aspect such as exposed surface area, nanoparticles connectivity and consolidation level. It is reviewed how design and optimization of different electrodes with specific microarchitectures (based on the arrangement manipulation of NiO nanoplatelets, used as building blocks), has allowed distinguishing the effects of each microstructural contribution in their final electrochemical responses, The modification of the Ni-based electrodes allows understanding how microstructural features infer the electron transport and the ion diffusion through the consolidated structure. The EIS analysis proves that the design of the porous hierarchical network of our semiconductors electrodes resulted in a good rate capability exhibiting a relaxation time constant, while a slight increase of the charge-transfer resistance is negligible if the exposed surface is high enough to maintain a high ion transport. The inclusion of non-noble nanoparticles, such as Ni NPs, in the NiO semiconductor microstructure and the optimum deposited mass and sintering treatment create a metal-ceramic electrode that enhances the charge transfer resistance while showing relaxation time in the range and maintaining an excellent capacitive behavior at quick charge/discharge rate.

1st January. New Paper Published. M.Coronada Fernández-Calderón, D. Romero-Guzmán, A. Ferrández-Montero, C. Pérez-Giraldo, J.L. González-Carrasco, M. Lieblich, R. Benavente, B. Ferrari, M.L. González-Martín, A. M. Gallardo-Moreno, "Impact of PLA/Mg films degradation on surface physical properties and biofilm survival", Coll. Surf. B: Biointerfaces, 185, 110617 (2020) DOI: 10.1016/j.colsurfb.2019.110617.

Physical surface parameters such as hydrophobicity, surface tension and zeta potential of PLA films reinforced with 10% Mg have been determined before and after degradation, as well as the biofilm formation capacity of Staphylococcus epidermidis. The addition of Mg to the films makes them less hydrophobic and the degradation also reduces the hydrophobicity and increases the negative charge of the surface, especially over long periods of time. Early biofilm formation at 8 h is consistent with the physical properties of the films, where we can observe a reduction in the bacterial biofilm formation. However, after 24 h of incubation, the biofilm formation increases significantly on the PLA/Mg films with respect to PLA control. The explosive release of Mg ions and other corrosion products within the first hours were not enough to prevent a greater biofilm formation after this initial time. Consequently, the Mg addition to the polymer matrix had a bacteriostatic effect but not a bactericidal one. Future works should aim to optimize the design and biofunctionality of these promising bioabsorbable composites for a degradation period suitable for the intended application.

1st January. New Paper Published. I. Msadok, N. Hamdi, M.A. Rodríguez, B. Ferrari, E. Srasra,, "Synthesis and characterization of Tunisian organoclay: Application as viscosifier in oil drilling fluid", Chem. Eng. Res. Des., 153, 427-434 (2020) DOI:10.1016/j.cherd.2019.11.010.

In this study, the viscosifiers for diesel oil drilling fluid were prepared using Tunisian clay modified with cationic surfactant for five concentration levels from 0.5 to 4.0 times the cationic exchange of purified clay (CEC). The organo-modified clay samples were characterized by X-ray diffraction (XRD), Infrared spectroscopy (FTIR), scanning electron micrography (SEM) and specific surface area (BET model). Oil–clays suspensions were investigated using polarized light optical microscopy (PLOM) and double cone rheometer. The influence of surfactant concentration on rheological properties of suspensions is related to the different microstructures development which depend on surfactant arrangement in the interlayer of clay. The results showed the growth of yield stress and consistency coefficient as the surfactant concentration is increased and the best behaviors were observed for the 3.0 CEC concentration. This sample was tested for two weight percents (5 and 10wt%), the higher Herschel Bulkley parameters (τ0=3.6Pa, K=0.397 and n=0.85) were found for the organoclay at 10wt%. The latest sample has the high thixotropy loop area so can be used as viscosity enhancer for the oil drilling fluid.

25 December. Season´s Greetings. We wish all of you a Merry Christmas and a Happy Year 2020. Background of our Christmas Card is a tape of a composite of Hydroxiapatite and Gelatin cast from an aqueous slurry and freeze dried. By E. Vazquez and A. Ferrandez [Enlarge image].


1st December. New Paper published. H. Besharatloo, M. de Nicolás, M. Wheeler, A. Mateo, B. Ferrari, E. Gordo, L. Llanes, J.J. Roa, "Carbon addition effects on microstructure and small-scale hardness for Ti(C,N)-FeNi cermets"  Int. J. Refract. Met. Hard Mater. 85, 105064 (2019). doi.org/10.1016/j.ijrmhm.2019.105064

The current study investigates the influence of carbon addition on the microstructural and micromechanical properties of Ti(C,N)-FeNi cermets with different ceramic/metal phase ratios. Evaluation of small-scale hardness is conducted by using high speed nanoindentation in  conjunction with statistical analysis. Subsequent statistical analysis was done by considering three mechanically distinct phases: Ti(C,N) particles, the metallic binder, and one exhibiting the composite behaviour (i.e. imprints probing two-phase regions). In general, it is found that porosity amount is reduced as ceramic/metal phase ratio decreases and carbon is added. Carbon addition is also observed to rise small-scale hardness, but only for two of the defined phases: metallic binder and the composite one. Similar trends are observed regarding the influence of ceramic/metal phase ratio and carbon addition on the inverse hardness-fracture toughness correlation measured under high applied loads.

1st November. New Paper published. M.E. Garcia-Ayala, S. Tarancon, Z. Gonzalez, B. Ferrari, J.Y. Pastor, A.J. Sanchez-Herencia, "Processing of WC/W composites for extreme environments by colloidal dispersion of powders and SPS sintering", Int. J. Refract. Met. Hard Mater., 84,105026 ( 2019,) DOI:10.1016/j.ijrmhm.2019.105026

Tungsten and tungsten carbide are materials proposed for extreme environment applications such as first plasma face, or cutting tools. The high melting temperature and strong bonding energy of both materials force the use of powder metallurgical processes and non-conventional sintering routes to achieve dense parts. In this paper tungsten and tungsten carbide powders are colloidally processed and mixed to achieve composite powders that are sintered later by Spark Plasma Sintering. Starting micrometric tungsten carbide and nanosized tungsten powders are dispersed in water at pH3. Composite powders with volumetric rations of 50WC/50W, 80WC/20W and 90WC/10W as well as pure WC and W are sintered by SPS following the dimensional change of the specimens during the process. It has been proved that complete coverage of the micronic WC by the nanosized W powders, achieved with this colloidal approach, makes the tungsten govern the initial sintering stages. The derivative of the sintering curves is used to detect the solid state reactive sintering temperature of W2C. After sintering, XRD and SEM observations indicate that all the mixture compositions yield to ceramic materials with different W2C/WC ratios, depending on the initial compositions. Flexure tests at room temperature show that composite materials present a slightly lower fracture strength than pure WC.



1st November. New Paper Published. H. Besharatloo, M. de Nicolás, J.J. Roa, M. Dios, A. Mateo, B. Ferrari, E. Gordo, L. Llanes,"Assessment of mechanical properties at microstructural length scale of Ti(C,N)–FeNi ceramic-metal composites by means of massive nanoindentation and statistical analysis", Ceram. Int. 45 (16), 20202-20210, (2019). DOI: 10.1016/j.ceramint.2019.06.292

Ti(C,N)-based cermets arise as excellent candidates to the traditional cemented carbides (WC–Co) due to their exceptional mechanical, tribological and thermal properties. In this work, microstructurally different Ti(C,N)–FeNi cermets were processed using a combination of colloidal and powder metallurgy techniques. Three distinct ceramic/metal phase ratios were used: 85/15, 80/20 and 70/30 (volume fraction) of Ti(C,N) and FeNi respectively. Small-scale hardness was evaluated by means of massive nanoindentation testing and statistical analysis of the gathered data, under the consideration of three mechanically different phases: Ti(C,N) particles, metallic binder and a composite-like one, corresponding to probing regions containing both constitutive phases. It is found that values of local hardness for both composite-like and metallic phases increase as the ceramic/metal phase ratio rises. In particular, local hardness values are determined to be significantly distinct for the metallic binder in the three cermets investigated. Estimated effective flow stress values for the metallic binder as well as detailed inspection of crack-microstructure interaction and fractographic features point out the effectiveness of FeNi as reinforcement phase and toughening agent for Ti(C,N)-base cermets.

DOI: 10.1016/j.actbio.2019.05.026

In this work we processed Mg reinforced PLA in the shape of films that would be suitable for tissue regeneration. Films with Mg content as high as 50 wt% were obtained without compromising the thermal stability of the polymer. Firstly, a successful dispersion of Mg microparticles was achieved by a breakthrough in processing introducing a colloidal step where organic additives were added to modify the Mg particle surface and promote a chemically stable suspension. The resulting colloidal suspension was then used as feedstock to obtain composite films by tape casting. The films show advantageous in vitro behaviour in terms of degradation, hydrogen release and oxygen permeability. In vitro behavior of PLA/Mg films demonstrated that Mg2+ ions increase the fibroblast cells growth. The viability with fibroblast cells (MEF) opens a window of opportunity for these composite films as bioabsorbable material for tissue engineering and wound dressing applications.

Excipient for Tablet Manufacturing via Direct Compression"
, Biomolecules, 9, 423 (2019) DOI:10.3390/biom9090423 (OPEN ACCESS)

This paper, in collaboration with members at the University of Belfast, presents the use of this biopolymer as excipient to prepare tablets as alternative uses for lignin (LIG). LIG was combined with microcrystalline cellulose (MCC) and used as excipients to prepare directly compressed tablets containing a model drug, tetracycline (TC). The excipients contained different concentrations of LIG: 100%, 75%, 50%, 25% and 0% (w/w). Two different compression forces were used (two and five tonnes). The presence of LIG in the tablets modified significantly the release profile and the maximum amount of TC released. Finally, a DPPH (2,2-diphenyl-1-picrylhydrozyl) assay was performed to confirm that the presence of LIG provided antioxidant properties to the formulations.

Gordo, "Influence of the processing route on the properties of  Ti(C,N)-Fe15Ni, Int. J. Refract. Met. Hard Mater. On line, (2019). https://doi.org/10.1016/j.ijrmhm.2019.105046

This study aims to understand the influence of powder preparation and processing steps on the microstructure and properties of Ti(C,N)-Fe15Ni cermets with 70 and 80 vol. % of ceramic phase. Two routes were used for powder preparation: (i) a colloidal approach, consisting of the preparation of stable aqueous suspensions of the powder particles and spray-drying to obtain easy-to-press granules, and (ii) conventional powder metallurgy route, consisting on wet ball milling of powders, with subsequent drying in rotary evaporator. As a result, COL samples exhibit a more homogeneous microstructural assemblage, higher small-scale hardness and mechanical integrity under sliding contact conditions. Compositions of materials must then be adjusted to adequate initial C addition with respect to the employed processing route, to account for the effects of the mixtures preparation stage.


1st August. New Paper Published. J. Yus, Z. Gonzalez, A.J.Sanchez-Herencia, A.Sangiorgi, N.Sangiorgi, D.Gardini, A.Sanson, C.Galassi, A.Caballero, J.Morales, B.Ferrari, "Semiconductor Water-Based Inks: Miniaturized NiO Pseudocapacitor Electrodes by Inkjet Printing", J. Eur. Ceram. Soc. 39 (9), 2908-2914 (2019). doi:10.1016/j.jeurceramsoc.2019.03.020

The paper presents the formulation, development and optimization of water-based inks of platelet-like nanoparticles. The as-synthesized Ni(OH)2 nanoparticles were dispersed and stabilized in aqueous suspension by PEI addition. The combination of DEG (cosolvent) with H2O shows the ideal values of surface tension and viscosity for piezoelectric inkjet printing, which exhibits a homogeneous jetting flow of the nanoplatelets suspension.

It is described a electrochemical overview of the NiO electrode behavior sintered at low temperature (325 °C). These printable pseudocapacitors tested by a three-electrode cell have showed a competitive specific capacitance, leading 92% and 78% of capacitance retention for 2000 cycles at scan rates of 1 and 2 A/g respectively, and a coulombic efficiency of 100%. This new finding is expected to be particularly useful for the designing of micro-pseudocapacitors.

10th June.New Paper published. Yus, J., Bravo, Y., Sanchez-Herencia, A.J., Ferrari, B., Gonzalez, Z., "Electrophoretic deposition of RGO-NiO core-shell nanostructures driven by heterocoagulation method with high electrochemical performance", Electrochim. Acta, 308, 363-372 (2019). DOI: 10.1016/j.electacta.2019.04.053

The paper presents a heterocoagulation route to prepare Reduced Graphene Oxide-Nickel Oxide (RGO/NiO) hybrid structures for their application as supercapacitor electrodes. The RGO intercalation among the NiO nanoplatelets has been carried out by electrostatic interactions of the synthetized particles which have been previously dispersed and stabilized in aqueous media to improve the assembly between both materials forming core-shell structures. The electrophoretic deposition (EPD) has been used to shape the composite onto 3D collector (Ni foams) controlling their growth and homogeneity. Electrodes have been thermal treated at 325 °C during 1 h to improve the electrochemical response since the formation of ceramic necks among NiO semiconductor nanoparticles preserves the microstructural integrity to enhance their connectivity avoiding the employment of binders, while RGO contributes with the electrochemical double layer effect to step up the specific capacitance by reducing the charge transfer resistance.

28th February. New Paper online. A. Sangiorgi, Z. Gonzalez, A. Ferrandez-Montero, J. Yus, A. J. Sanchez-Herencia, C. Galassi, A. Sanson and B. Ferrari, "3D Printing of Photocatalytic Filters Using a Biopolymer to Immobilize TiO2 Nanoparticles", J. Electrochem. Soc. 166 (5), H3239-H3248 (2019). doi:10.1149/2.0341905jes

The paper describes titanium oxide-based photocatalytic filters produced by Fused Deposition Modelling (FDM) using biopolymers obtained from renewable biomass resources. The thermoplastic route allows shaping composites through the immobilization of photoactive TiO2 nanoparticles in an environmentally friendly bioplastic such as the polylactic acid (PLA). Composites with an inorganic charge of 30wt% of TiO2 nanoparticles (NPs) exhibit a 100% methyl orange (MO) degradation after 24 h of light exposition due to the extremely uniform dispersion of the nanophase within the polymer matrix in the FDM feedstock.

The proposed new route of processing improves the dispersion of nano-charges comparing with the traditional thermo-pressing routes used for mixing thermoplastics based composites, avoiding the thermal degradation of the polymer and providing a customised product.

7th January. We congratulate our good friend and collaborator Dr. Raul Bermejo, from the Institute of Structural and Functional Ceramics (ISFK) at the University of Leoben, who has been granted with an ERC Consolidator Grant for the project CeraText "Tailoring Microstructure and Architecture to Build Ceramic Components with Unprecedented Damage Tolerance".

Colloidal techniques are proposed to overcome the agglomeration of Ti(C,N) particles and the low compressibility of the metal-ceramic blends. Aqueous suspensions of steel powders and Ti(C,N) particles are prepared followed by spray-dry to obtain spherical granules able to be processed by pressing and sintering, avoiding oxidation of powders. The agglomerates present higher compressibility than blends, and sintered materials show higher density and hardness.

15th February. New Paper. C. Mendoza, Z. Gonzalez, E. Gordo, B. Ferrari and Y. Castro, “Protective nature of nano-TiN coatings shaped by EPD on Ti substrates”, J. Eur Ceram. Soc, 38 (2) 495-500 (2017)doi:10.1016/j.jeurceramsoc.2017.09.046.

Uniform and dense TiN coatings have been obtained onto substrates of Ti by Electrophoretic Deposition (EPD). A deposition time of 5 min has been enough to obtain a cohesive layer of 7–8 μm in thickness. The coatings were thermally treated in vacuum atmosphere at 1200 °C for 1 h with heating and cooling rates of 5 °C min−1. The hardness and corrosion resistance of TiN coatings have been evaluated. The nanohardness values of the polished samples have been increased from 2.8–4.8 GPa up to 6.5–8.5 GPa. Besides, the corrosion current density has been reduced more than one order of magnitude obtaining a protective efficiency of 82%. These values demonstrate the strong impact of the colloidal processing over the specific properties of the material.

It is focused on the processing of Ti(C,N)-based cermets using fine powders (1–3 μm) in suspension. By combining colloidal and powder metallurgy techniques the uniformity of the phase distribution and its reactivity is promoted, leading to 99.9% dense cermets with Hardness values as high as 1300HV30.


8th November. New Paper. J. Yus, B. Ferrari, A.J. Sanchez-Herencia, A. Caballero, J. Morales and Z. Gonzalez, “In Situ Synthesis and Electrophoretic Deposition of NiO/Ni Core-Shell Nanoparticles and Its Application as Pseudocapacitor”,Coatings, 7, (11) 193 (2017). doi:10.3390/coatings7110193

NiO/Ni core–shell hybrid nanostructures as binder-free electrodes to their application in supercapacitors are synthesized and processed by electrophoretic deposition (EPD) in aqueos media. After thermal treatment the necks created among ceramic-metallic nanoparticles preserve the structural integrity of the microstructure avoiding avoiding the employment of binders and enhancing in the interparticles connectivity.
Specific capacitance of NiO/Ni electrodes is 755 F/g. This value doubles the results of simple NiO nanoplatelets due to the presence of metallic Ni nanoparticles.


1st November. New Paper. E. Espinosa, R. Sánchez, Z. González, J. Domínguez-Robles, B. Ferrari, A. Rodríguez, “Rapidly growing vegetables as new sources for lignocellulose nanofibre isolation: Physicochemical, thermal and rheological characterisation”,Carbohydrate Polym., 175, 27-37 (2017). doi:10.1016/j.carbpol.2017.07.055

The aim of this study has been to study the suitability of tagasaste and leucaena as new sources of biomass for lignocellulosic nanofibre production. LCNF were produced using three different pre-treatments, TEMPO-mediated oxidation, enzymatic treatment, or a mechanical process. XRD and FTIR analysis show that homogenisation has a strong negative effect on the crystallinity index; however, the higher lignin content of tagasaste (10%) protects the fibre, causing a smaller decrease in crystallinity. The thermal stability of LCNF is also affected by the high lignin content in the case of tagasaste, which exhibited maximum degradation temperatures of 340–315 °C, that were higher than those for leucaena (330–310 °C). A strong shear thinning behaviour was observed in most of the LCNF, which revealed a great degree of interconnectivity in the gel like-network.

5th November. Our Group has proved the full yield of the EPD process for suspensions with such as low solid loading as 1 g/L. Suspensions are a mixture of Ni(OH)2 and Carbon Black (80/20 v/v) prepared in ethanol and deoinized water used in the fabrication of anodes for Li-Batteries (A. Caballero et al., J. Power Sources, 238 (2013) 366). The elevated suspension stability and an adequate conductivity leads to the complete deposition of the suspended powder. Results are published in the Thesis of Dr. Sandra Cabanas-Polo “Ultrasound assisted synthesis of Ni-based nanostructures”, supervised by Dr. A.J. Sanchez-Herencia and Dr. B. Ferrari.
