In this study, zinc-doped (α-Fe2O3:Zn), silver-doped (α-Fe2O3:Ag) and zinc/silver co-doped hematite (α-Fe2O3:Zn/Ag) nanostructures were synthesized by spray pyrolysis. The synthesized nanostructures were used as photoanodes in the photoelectrochem

We report on the properties of hematite thin films prepared by spray pyrolysis on fluorine-doped tin oxide (FTO)-coated glass substrates and investigated the effect of the spray volume, tetraethoxysilicate treatment of the hematite, and post-annealin

Introduction This review addresses metabolic diversities after grain feeding of cattle using artificial total mixed ration (TMR), in place of pasture-based feeding. Objectives To determine how grain feeding impairs the deuterium-depleting functions o

With the increasing performance of organic solar cells (OSCs), the design of stable donor materials is of paramount importance. In this work, we synthesised a simple alternating copolymer with thiophene and BDT (P3T-BDT) units to understand the impac

Plasmonic coupling of metallic nanoparticles and adjacent pigments can dramatically increase the brightness of the pigments due to the enhanced local electric field. Here, we demonstrate that the fluorescence brightness of a single plant light-harves

Hematite, a common type of iron oxide, is a promising material for solar technologies because of its small band gap that allows for solar radiation absorption in the visible region, low toxicity in aqueous solutions, easy synthesis, and natural abund

The main light-harvesting pigment-protein complex of cyanobacteria and certain algae is the phycobilisome, which harvests sunlight and regulates the flow of absorbed energy to provide the photochemical reaction centres with a constant energy throughp

LHCII — the main light-harvesting complex of plants and green algae — is the most abundant membrane protein on earth. Here, we investigate theoretically the effect of exciton-plasmon coupling on LHCII’s fluorescence quantum yield and compare ou
