Whole cells of the genetically engineered Saccharomyces cerevisiae strain TMB4100 (1% PGI, YMR226c) were used as the biocatalyst for the kinetic resolution of racemic bicyclo[3.3.1]nonane-2,6-dione rac-1. The yeast’s phosphoglucose isomerase activity was decreased, and the short-chain dehydroge...

The conformational stability of newly synthesised bicyclo[3.3.1]nonane-2,6-dione C9H12O2 (D26) and bicyclo[3.3.1]nonane-2,9-dione C9H12O2 (D29) was studied. Ab initio calculations (HF level using 6-31G∗∗ basis set) reveal that due to six-membered ring inversion four conformers exist in the case ...

Screening of various vegetables as biocatalysts for the stereoselective bioreduction and resolution of racemic bicyclo[3.3.1]nonane-2,6-dione was performed. Vegetables of the family Apiaceae, i.e. the roots of parsnip (Pastinaca sativa), celery (Apium graveolens), parsley (Petroselinum crispum) ...

Nowadays, it is of great significance to develop a novel fluorescent chemosensor for Cd(II) ions detection with cost-effective, rapid, facile and applicable to environment and biological milieus. Herein, we report a new peptide-based fluorescent chemosensor DSC (Dan-Ser-Cys-NH2) based on dipepti...

A novel imidazo[1,2-a]pyridine-rhodamine ratiometric fluorescent probe IP-Hg for Hg2+ based on a fluorescence resonance energy transfer mechanism has been developed. The probe has been proved to show high sensitivity and high selectivity toward Hg2+. Furthermore, it could be used for imaging Hg2...

The purpose of this study was to investigate the endocrine-mediated effects of the benzene-related compounds with reference to Organization for Economic Co-operation and Development (OECD) Test Guideline No. 407. Rats were orally gavaged with 0, 10, 50, and 250 mg/kg/day of 1-chloro-4-(chloromet...

Reaction of O-trimethylsilyl (O-TMS) derivatives of α-dimethylamino ketones with chloro(chloromethyl)dimethylsilane led to the formation of six-membered heterocyclic compounds with tetracoordinated silicon atom - 3,4-dihydro-2H-1,4,2-oxazasilin-4-ium chlorides. The exchange reactions of 2,2,4,4...

Heat-capacity measurements between 5 and 350 K have been performed upon a microcrystalline sample of Y(OH)3. The heat capacities can be represented by a simple sigmate curve; no anomalous behavior was observed. Comparison with previously published results for the iso-anionic compounds La(OH)3 an...

Three unique phases of hydrous lutetium oxide have been isolated. An aging series under strict controls presents evidence of phase transitions from an amorphous gel to LuOOH. The newly found cubic Lu(OH)3 is one of the isolated phases. Lattice paraments obtained from X-ray diffraction methods ar...

The crystal structure of 1:1 lutetium/indium trihydroxide has been determined by means of single- crystal X-ray diffraction techniques. The compound is isostructural with pure Lu(OH)3 having a polyhedral framework consisting of two slightly distorted pentagonal dodecahedra and twelve heptahedra ...

The thermal decomposition of crystalline europium hydroxide has been studied by dynamic (differential thermal analysis and thermogravimetry) and static (fourier transform infrared and high-resolution photoluminescence spectroscopies) methods. It was deduced that crystalline europium hydroxide wa...

The amorphous lanthanide hydrous oxides are structurally related to lanthanide oxyhydroxides and trihydroxides. The bulk short-range orders (SROs) of amorphous europium, gadolinium, and terbium hydrous oxides are the subject of this work. The instrumental arrangement, data collection, and data r...

Time-resolved laser-induced fluorescence has been used to investigate Eu complexes formed with a few main ligands encountered in natural waters: hydroxide, carbonate and humic substances. By varying pH and concentrations of ligands at fixed europium concentration and ionic strength, it was possi...

In this study, we introduce a novel route to produce down and upconverting Eu3+/Yb3+ co-doped oxysulfide nanorods, which display strong red emission at 620 nm under Vis (460 nm) or NIR (976 nm) wavelength excitation. An in-depth analysis of the synthesis parameters such as lanthanides concentrat...

Highly stable and multifunctional fluorescent quantum dots are particularly attractive in practical applications. Here, a new kind of ultra-small-sized silicon quantum dot-gadolinium (SiQD-Gd) was successfully fabricated by a newly-designed facile hydrothermal growth and chelating method. The ob...

The success of synthesis of varied nanostructures requires the precise precipitation of materials at particular location.
