Introduction: Ammonia in form of ammonium ions is toxic and could decrease the dissolved oxygen in water and endanger the aquatic life. The aim of this study is the removal of ammonium using oxidation and adsorption by catalytic ozonation and clinoptilolite zeolite, respectively. Methods: The research method is Experimental. First, optimal pH of ammonium adsorption on carbon catalyst (5 g/L), ...

Biophysical-factor-dependent cellular uptake of nanoparticles (NPs) through receptor-diffusion-mediated endocytosis bears significance in pathology, cellular immunity and drug-delivery systems. Advanced nanotechnology of NP synthesis provides methods for modifying NP surface with different ligand distributions. However, no report discusses effects of ligand distribution on NP surface on recepto...

The consideration of discrete variables (e.g. catalyst, ligand, solvent) in experimental self-optimization approaches remains a significant challenge. Herein we report the application new mixed variable multi-objective optimization (MVMOO) algorithm for chemical reactions. Coupling MVMOO with an automated continuous flow platform enabled identification trade-off curves different performance cri...

Colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. In this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (PbS) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. The PbS nanocrystals (QDs) were synthesized in a non-coordinating solvent, 1-oc...

A series of single-molecule dysprosium (Dy 3+) complexes consisting b diketonate ligands, as water-containing complexes, and the auxiliary triphenylphosphine oxide (tppo)ligand water free were investigated potential white light emitters. The coordination environment choice ligands play an important role in behavior yellow blue emission Dy 3+ based on sensitization efficiency ion by ligands. By ...

Three mononuclear Schiff-base–Ni( ii ) complexes act as electrocatalyst for hydrogen evolution reaction using acetic acid and trifluoroacetic the substrates. With increase in chain length of ligand, efficiency catalyst decreases.

This work highlights that a ligand-based approach to develop Pd( ii )-based amphiphilic polymeric nanoparticles enhances their efficiency for pro-dye/drug activation in water and complex media.

in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...
