Cellulose nanocrystals (CNC) are drawing increasing attention in the fields of biomedicine and healthcare owing to their durability, biocompatibility, biodegradability and excellent mechanical properties. Herein, we fabricated using fused deposition modelling (FDM) technology 3D composite scaffolds from polylactic acid (PLA) and CNC extracted from...

Additive manufacturing of Polymer-Derived Ceramics (PDCs) is regarded as a disruptive fabrication process that includes several technologies such as light curing and ink writing. However, 3D printing based on material extrusion is still not fully explored. Here, an indirect 3D printing approach combining Fused Deposition Modeling (FDM) and replica...

The conversion of CO 2 into desirable multicarbon products via the electrochemical reduction reaction holds promise to achieve a circular carbon economy. Here, we report a strategy in which we modify the surface of bimetallic silver-copper catalyst with aromatic heterocycles such as thiadiazole and triazole derivatives to increase the conversion of...

The conversion of CO 2 into desirable multicarbon products such as ethylene and ethanol via the carbon dioxide reduction reaction (CO 2 RR) hold promise to achieve a circular carbon economy. The develop of such a technology is currently hampered by the lack of catalysts, which can drive the reaction at industrially relevant current densities with h...

Hydrogen Evolution Reaction (HER) is an attractive technology for chemical conversion of energy. Replacement of platinum with inexpensive and stable electrocatalysts remains a major bottleneck hampering large-scale hydrogen production by using clean and renewable energy sources. Here, we report electrocatalytically active and ultra-stable Polymer-D...

Nanocomposite materials are widely studied because of their unique design opportunities and properties. They can be classified into three main groups in function of the matrix used: polymer-based, ceramic-based, and metal-based nanocomposites. The nanofiller choice is one of the most important steps because it will improve the nanocomposite propert...

The most critical challenge in hydrogen fuel production is to develop efficient, eco-friendly, low cost electrocatalysts for water splitting. In this study, self-supported carbon nanofiber (CNF) electrodes decorated with nickel/nickel oxide (Ni/NiO) and palladium (Pd) nanoparticles (NPs) were prepared by combining electrospinning, peroxidation, and...
Article
Living tissues, heterogeneous at the microscale, usually scatter light. Strong scattering is responsible for the whiteness of bones, teeth, and brain and is known to limit severely the performances of biomedical optical imaging. Transparency is also found within collagen-based extracellular tissues such as decalcified ivory, fish scales, or cornea....

As organic dyes are a major source of pollution, it is important to develop novel and efficient heterogeneous catalysts with high activity for their degradation. In this work, two innovative techniques, atomic layer deposition and electrospinning, were used to prepare palladium nanoparticles (Pd NPs) supported on carbon nanofibers (CNFs). The sampl...

Nanolaminate membranes made of two-dimensional materials such as graphene oxide are promising candidates for molecular sieving via size-limited diffusion in the two-dimensional capillaries, but high hydrophilicity makes these membranes unstable in water. Here, we report a nanolaminate membrane based on covalently functionalized molybdenum disulfide...
Article
A series of polyaluminosilazanes was synthesized by reaction of dimethylethylamine alane complex with polysilazanes. Starting from different dichlorosilanes, polysilazanes were obtained by means of ammonolysis. The latter reacted with the alane complex and led to solid polyalumino(carbo)silazanes that can be described as “custom-made” polymers sinc...
Article
Herein, mesoporous monolithic (3D) boron nitride (BN) structures have been synthesized by a template-assisted polymer-derived ceramic route. Polyborazylene was selected to impregnate monolithic activated carbon used as template. It supplies, after pyrolysis and template removal, BN components with controlled crystallinity and tunable textural prope...

Two series of co-polymers with the general formula [B(C2H4SiCH3(NH)x(NCH3)y)3]n, i.e., composed of B(C2H4SiCH3NH)x and B(C2H4SiCH3NCH3)y (C2H4 = CHCH3, CH2CH2) building blocks in a well defined x:y ratio, have been synthesized by hydroboration of dichloromethylvinylsilane with borane dimethyl sulfide followed by the successive reaction with lithium...
Article
The design of Si-(B)-C materials has been investigated with a detailed insight into the precursor chemistry and processing, the precursor-to-ceramic transformation and the ceramic microstructural evolution at high temperature. In the early stage of the process, the reaction between allylhydridopolycarbosilane (AHPCS) and borane dimethyl sulphide wa...

Functional boron-modified polysilazanes with various Si/B ratios have been synthesized as SiBCN precursors to supply silicoboron carbonitride (SiBCN) ceramics with the desired phase distribution and homogeneity after pyrolysis. This polymer-derived ceramics (PDCs) route has been demonstrated to allow polymer shaping to produce three dimensional (3D...
Article
A series of boron-modified polyorganosilazanes was synthesized from a poly(vinylmethyl-co-methyl)silazane and controlled borane dimethyl sulfide amounts. The role of the chemistry behind their syntheses has been studied in details by solid-state NMR, FT-IR and elemental analyses. Then, the intimate relationship between the chemistry and the process...

Controlling the surface grafting of species at the nanoscale remains a major challenge, likely to generate many opportunities in materials science. In this work, we propose an original strategy for chemical surface functionalization at the nanoscale, taking advantage of localized surface plasmon (LSP) excitation. The surface functionalization is de...

Hexagonal boron nitride (h-BN) attracts considerable interest because its structure is similar to that of carbon graphite while it displays different properties which are of interest for environmental and green technologies. The polar nature of the B-N bond in sp(2)-bonded BN makes it a wide band gap insulator with different chemistry on its surfac...

Late transition metal have attracted considerable interest for catalytic applications. Their immobilization over supports with tailored porosity is advantageous for nanosizing metal particles and avoiding their agglomeration which is known to bring a serious issue to the catalytic performance. Herein, ordered mesoporous silicon nitride (Si3N4) nano...

The present paper reports the preparation of sintering additive-free Si–B–C–N monoliths by spark plasma sintering (SPS) under nitrogen of polymer-derived Si–B–C–N powders. Powders are synthesized in nitrogen or ammonia atmosphere to modify their carbon content. The nitrogen-treated powders sintered in the temperature range 1500–1900 °C lead to mono...

The spray-pyrolysis of borazine at 1400 °C under nitrogen generates boron nitride (BN) nanoparticles (NPs). The as-prepared samples form elementary blocks containing slightly agglomerated NPs with sizes ranging from 55 to 120 nm, a Brunauer-Emmett-Teller (BET)-specific surface area of 34.6 m2 g−1 and a helium density of 1.95 g cm−3. They are relati...
