• Cubane core in Co-oxo complexes studied using XAS to probe its spectroscopic nature. XANES shows presence of octahedrally coordinated Co 3+ ions cubane structure. EXAFS confirm octahedral with 6 O/N, 3 Co-Co backscattering forming core. simulation indicate interaction co-crystallizing salts NaNO and NaClO 4 . Formation defect dicubane 2+ /Co predicted by simulation. The formation effect co-cr...

Project Goals: The project is to develop correlated optical (Raman and SH-OCT) and mass spectrometric (SIMS and MALDI MS) imaging approaches for spatial and temporal characterization of lignocellulosic materials at specific processing stages. The ability to efficiently use lignocellulosic materials (LCMs) to feed the biorefinery of the future depends on high-efficiency pre-enzymatic processing ...

Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...

In this article, the HMP-3 wastewater treatment process with natural minerals (vermiculite, zeolite, dolomite, saponite, shungite, bentonite, basalt minerals), rice husk, 1% NaClO (sodium hypochlorite) and 3% H 2 O (hydrogen peroxide) solutions will be discussed. According to research results, activation of samples used for in form sodium hypochlorite solution hydrogen peroxide shows high effic...

Várias fases estacionárias baseadas em derivados de polissacarídeos e proteínas foram avaliadas para a resolução de alguns fármacos quirais e seus metabólitos. As fases estacionárias baseadas em polissacarídeos CHIRALCEL OD-H, CHIRALCEL OB-H, CHIRALCEL OJ, CHIRALPAK AD e CHIRALPAK AS foram avaliadas em condições de fase normal, usando hexano:2-propanol como fase móvel. Dietilamina ou ácido trif...

Chiral MnIII (salen) complex supported on modified ZPS-PVPA (zirconium poly(styrenephenylvinylphosphonate)) and ZPS-IPPA (zirconium poly(styrene-isopropenyl phosphonate)) were prepared using –CH2Cl as a reactive surface modifier by a covalent grafting method. The supported catalysts showed higher chiral induction (ee: 72%–83%) compared with the corresponding homogeneous catalyst (ee: 54%) for a...

Rate constants for acid catalysis of the reactions of N-chlorodimethylamine (1), N-chloro-2,2,2-trifluoroethylamine (2) and N,N-dichlorotaurine (3) with iodide ion were determined in H(2)O at 25 degrees C and I = 0.5 (NaClO(4)). The failure to detect significant catalysis by general acids of chlorine transfer from 1 to the nucleophile, together with the observed inverse solvent deuterium isotop...
