Drying well-mixed Ni(CH 3 COO) 2 -PVP solution results in incorporation of metal precursor NPs throughout the polymer sheets. Adjusting salt content leads to produce N-doped and Ni-decorated rGO which is an effective electrocatalyst for H production from tri(ammonium) phosphate.

Phosphorus is one of the major components required for the metabolic activities and for the growth of any organism. Many soil organisms are known to solubilize inorganic phosphates. Aspergillus niger isolated from the soil showed extensive solubilization of Tri-calcium phosphate.It was observed that the solubilization was due to drop in pH.Acidification was due to production of organic acids by...

In mitochondria, carbamoyl-phosphate synthetase 1 activity produces carbamoyl phosphate for urea synthesis, and deficiency results in hyperammonemia. Cytoplasmic carbamoyl-phosphate synthetase 2, however, is part of a tri-functional enzyme encoded by CAD; no human disease has been attributed to this gene. The tri-functional enzyme contains carbamoyl-phosphate synthetase 2 (CPS2), aspartate tran...

Chitosan-based nanogels have been widely applied as drug delivery vehicles. Spray-drying of said nanogels allows for the preparation of dry powder nano-embedded microparticles. In this work, chitosan-based nanogels composed of chitosan, alginate, and/or sodium tri-penta phosphate were investigated, particularly with respect to the impact of composition on the resulting physicochemical propertie...

The estrogenic activity of phthalate esters for dental use as plasticizers was concerned. To study the feasibility of candidate chemicals for phthalate tissue conditioners, three candidate plasticizers, di-n-butyl sebacate, acetyl tributyl citrate and tri-n-butyl phosphate together with conventional plasticizers were examined for estrogenic activity and cytotoxicity using three estrogenicity as...

Introduction: Many molecules can be labeled by iodine. Some of labeled substances are used for investigations of cancer treatment, biodistribution study in body, receptor binding, secrete pathway etc. Peptides are biomolecules and can be labeled by 131Iodine. ICD- 85 is a tri-peptide derived from Iranian brown snake venom and scorpion venom. This tri-peptide treats cancer by i...

Indoor dust has been acknowledged as a major source of flame retardants (FRs) and dust ingestion is considered a major route of exposure for humans. In the present study, we investigated the presence of PBDEs and alternative FRs such as emerging halogenated FRs (EHFRs) and organophosphate flame retardants (PFRs) in indoor dust samples from British and Norwegian houses as well as British stores ...
