In this study, tin/tinoxide/multiwalled carbon nanotube (Sn/SnO2/MWCNT) nanocomposites were produced as anode materials for Li-ion batteries by a two-step process. Metallic tin was evaporated onto free-standing MWCNT buckypapers having controlled porosity and subsequently rf plasma oxidized in Ar:O2 (1:1) gas mixture. Besides, Sn/SnO2 nanocomposites were produced in the same conditions onto sta...

According to recent research, the use of nanoparticles as a gas-sensitive material increases the selectivity and sensitivity and shortens the response time of a sensor. However, the synthesis of SnO2 nanoparticles presents many difficulties. The following article presents a simple and inexpensive method for the synthesis of SnO2 nanoparticles. The influence of the surfactant and polymer choice ...

The bulk SnO2 was synthesized by oxidizing the fine powder (50 mesh) of metallic tin (purity 99.99, Aldrich) powder at 750°C for 9 hrs hours in programmable temperature controlled furnace. The gross structure and phase purity of the powder sample ground from sintered pellets were examined by powder X-ray diffraction technique. The phase identification /gross structural characteristics of synthe...

A second addition of lmol% of CoO to a pre calcined SnO2-based ceramic doped with 1.0mol% of CoO, 0.05mol% of Nb2O5 and 0.05mol% of Cr2O3 promotes the appearance of a secondary phase, Co2SnO4, besides the SnO2 cassiterite phase, when the ceramic was sintered at 1350°C/2h. This was observed using X-ray powder diffraction, scanning electron microscopy and energy dispersive X-ray techniques. Rietv...

Stretchable and transparent inorganic semiconductors play a key role for the next generation of wearable optoelectronics. Achieving stretchability in intrinsically rigid inorganic materials is far more challenging than in polymers and metals. Here, we present a low-cost and scalable strategy to engineer inorganic semiconductors into a buckling open-mesh configuration, by which extraordinary str...

A three-dimensional porous architecture makes an attractive electrode structure, as it has an intrinsic structural integrity and an ability to buffer stress in lithium-ion batteries caused by the large volume changes in high-capacity anode materials during cycling. Here we report the first demonstration of a SnO2-coated macroporous Cu foam anode by employing a facile and scalable combination of...

10 Influence of phase composition, structural peculiarities and grain size of Fe2O3–SnO2 nanocomposites prepared by sol–gel technology on gas-sensitive properties of the corresponding gas sensors has been studied in the paper. The characteristics of thin film sensors were obtained with regards to NO2 and C2H5OH. Behaviour of thick film sensors was estimated in humid C2H5OH ambient. High sensiti...
