Graphene and other two-dimensional materials have been used as catalysts in the oxygen reduction reaction (ORR) in fuel cells with a few limitations in terms of the onset potential and number of electrons transferred per ...

Hydrogen can be generated by visible light irradiation of semiconductor heterostructures of the type ZnO/Pt/CdS and TiO2/Pt/CdS. In order to understand the dependence of hydrogen generation on the properties of the ...

Mechanical properties of single-walled carbon nanohoms (SWNH) and SWNH plus few-layer graphene (EG)-reinforced poly(vinyl alcohol) (PVA) matrix composites have been measured using the nanoindentation technique. The elastic ...

Composites of boron nitride (BN) and carboxylated graphene are prepared for the first time using covalent cross-linking employing the carbodiimide reaction. The BN(1-x)G(x) (x approximate to 0.25, 0.5, and 0.75) obtained ...

Novel properties of graphene have been well documented, whereas the importance of nano-sheets of, MoS2 and other chalcogenides is increasingly being recognized over the last two to three years. Borocarbonitrides, BxCyNz, ...

Perovskite oxides of the Ln(0.5)A(0.5)MnO(3) (Ln=lanthanide, A=Sr, Ca) family have been investigated for the thermochemical splitting of H2O and CO2 to produce H-2 and CO respectively. The amounts of O-2 and CO produced ...

(ZnS)(0.4)(AgInS2)(0.6) nanocrystals (NCs) capped by S2- ions exhibit interesting electronic properties, absorbing visible light along with a suitable band alignment as well as properties such as high surface area providing ...

Nanosheets containing few-layers of ferroelectric Aurivillius family of oxides, Bi(2)A(n-1)B(n)O(3n+3) (where A = Bi3+, Ba2+ etc. and B=Ti4+, Fe3+ etc.) with n=3, 4, 5, 6 and 7 have been prepared by reaction with n-butyllithium, ...

Infrared spectroscopy shows the occurrence of a transition to a phase of lower symmetry on cooling KLiSO4 below 170K, but there appears to be no change in the point group symmetry of the SO42- ion across the C66−C43v ...

Substitution of Ba by Sr in BaPb1−xBixO3 narrows the superconducting composition range in addition to lowering the Tc; the decrease in Tc with Sr content is nonlinear. The effect of Sr substitution is found to be more ...
