Spray‐pyrolyzed Cd‐substituted kesterite thin‐films for photovoltaic applications: Post annealing conditions and property studies
(Elsevier, 2023)Kesterite materials were investigated for their suitability as absorber layers for thin-film photovoltaic cells. Thin- films of copper cadmium zinc tin sulfide (Cu2CdxZn1-xSnS4) were prepared by spray pyrolysis on soda-lime ... -
Surface-modified polyacrylonitrile nanofibers as supports
(Springer Verlag, 2017)Polyacrylonitrile nanofibers (PAN-nfs) are one of the most studied nanofibres because of their excellent characteristics, such as good mechanical strength, chemical resistance, and good thermal stability. Due to the easy ... -
Sustainable fuels: Lower alcohols perspective
(Wiley, 2023)In the coming years, energy sources will play a vital role in global development. Biofuels made from sustainable sources are essential for the global economy's long-term viability and the reduction of greenhouse gas ... -
Synthesis and characterisation of a polysulfone-polyvinyl alcohol hydrogelic material
(ESG, 2016)Hydrogels are flexible materials that have found a niche in membrane science owing to their ability to absorb water without dissolving. The synthesis of polyvinyl alcohol-polysulfone hydrogel in the presence of N-hydroxy ... -
Synthesis and electronic properties of Alkyl- and alkyloxy-cucuminoids
(Elsevier, 2013)Two series of p‐alkyl‐ and p‐alkoxy‐substituted curcuminoids were synthesized. The validity of the proposed structures was checked on the basis of their high resolution mass spectra as well as NMR, IR and electronic ... -
