Article
The microstructure and amplitude dependences of the Young’s modulus E and internal friction (logarithmic decrement δ), and microplastic properties of biocarbon matrices BE-C(Fe) obtained by beech tree carbonization at temperatures Tcarb = 850–1600°C in the presence of an iron-containing catalyst are studied. By X-ray diffraction analysis and transm...
Article
A facile and low-cost method has been employed to fabricate MnO2/C hybrid materials for use as binder-free electrodes for supercapacitor applications. Biocarbon monoliths were obtained through pyrolysis of beech wood, replicating the microstructure of the cellulosic precursor, and serve as 3D porous and conductive scaffolds for the direct growth of...

We report here on controlled synthesis, characterization and electrochemical properties of different polymorphs of niobium pentoxides grown by CVD of new single-source precursors. Nb2O5 films deposited at different temperatures showed systematic phase evolution from low-temperature tetragonal (TT-Nb2O5, T-Nb2O5) to high temperature monoclinic modif...

Catalytic hydrogen combustion was studied with H2/air mixtures in conditions that simulate the H2 concentration of the exhaust gases from fuel cells (3-4% v/v H2 in air). Pt-impregnated monoliths based on porous biomorphic SiC (bio-SiC) substrates were employed for the first time for this reaction. Capillary forces were exploited for the incipient...

Lithium metal solid-state batteries (SSBs) are expected to outperform the current lithium-ion battery technology, limited by the performance, energy density, and safety issues. One of the most promising classes of solid electrolytes for SSBs are polymer-inorganic composites. However, incompatibility between inorganic and polymer phases may affect t...

Solid state batteries (SSB) are currently considered as one of the most reliable technologies to replace lithium-ion batteries (LIB). Nevertheless, the development and further industrialization of SSB still have a lot of scientific and technological challenges at material, processing, upscale, and cell levels. In this context, SSB components are be...
