In higher plants, high light conditions trigger the activation of non-photochemical quenching (NPQ), a process of photoprotective light energy dissipation, via acidification of the chloroplast lumen. Spectral changes occurring in the neoxanthin domain of the major light harvesting antenna complex (LHCII) have previously provided indirect evidence of a protein conformational switch during NPQ. W...

Among the main restrictions for the implementation of advanced oxidation processes (AOPs) for removal of micropollutants present in reverse osmosis (RO) brines of secondary effluents account the quenching performed by background organic and inorganic constituents. Natural organic matter (NOM) and soluble microbial products (SMP) are the main effluent organic matter constituents. The inorganic f...

for the first time, this research reports the formation of nanoporous layers of metals on the surface of metal substrates by raney method and their conversion to corresponding porous perovskite layers. the noble metals doped perovskites are used as catalytic converter for reducing automotive pollutants. the use of perovskite as a substrate for the noble metals can reduce the need for such metal...

Fluorescein is one of most used fluorescent labels for characterizing biological systems, such as proteins, and is used in fluorescence microscopy. However, if fluorescein is to be used for quantitative measurements involving proteins then one must account for the fact that the fluorescence of fluorescein-labeled protein can be affected by the presence of intrinsic amino acids residues, such as...
