We have developed a novel method of manufacturing and assembling process termed nano-pelleting [1-2], which refers to large-scale handling and long-range order assembly of individual carbon nanotubes (CNTs). The nano-pelleting concept overcomes the limitation of very small-scale order by embedding carbon nanotubes into micro-scale pellets. This technique includes vertically growing single stran...

Some tungsten catalysts of interest that are synthesized bismuth tungstate (BT) and Tetrabutylammonium decatungstate (TBADT), using two consolidated procedures. BT is used as a photo-catalyst for the simulated solar light degradation ofloxacin (OFL) antibiotic under relevant real conditions (µg L−1, fresh water) with limit 0.05 g L−1 catalyst. A quantitative drug decomposition occurred followin...

in this work firstly mgfe2o4 nanoparticles were synthesized via a microwave-assisted method. the product was calcinated at 900 ºc for 2h. at the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform infrared (ft-ir) spectroscopy. vibr...

Background & Aims of the Study: Pharmaceutical compounds have a variety of forms and applications. Specific amounts of toxic organic compounds in the process of their manufacturing and utilization cause environmental pollution problems. So, degradation and removal these compounds are necessary. The aim of this paper is the study photocatalytic degradation of ciprofloxacin drug in aqueous soluti...

Artificial photosynthesis is a very attractive and a desirable way to solve the rising energy demand. In order to harvest energy directly from sunlight catalyst for oxygen reduction and evolution reaction are at the core of key renewable-energy technologies including fuel cells and water splitting. Herein, tungsten oxide-reduced graphene oxide (WO3-rGO), cobalt oxidereduced graphene oxide (Co3O...

The discovery of catalysts capable of driving water oxidation at relatively low overpotential is a key challenge for efficient photoinduced water oxidation. The mononuclear Ru(II) polypyridyl complex (1) [Ru(NPM)(H2O)(pic)2](2+) (NPM = 4-tert-butyl-2,6-di-(1',8'-naphthyrid-2'-yl)-pyridine, pic = 4-picoline) has been examined as a catalyst for visible-light-driven water oxidation in a three-comp...

biological structures and functions. It is suitable for the analysis of biological interactions because it is based on the affinity of the ligand moiety. Various photophors, such as phenyldiazirine, arylazide and benzophenone, were used. Comparative irradiation studies of these three photophors in living cells suggested that a carbene precursor, (3-trifluoromethyl) phenyldiazirine, is the most ...
