Four new organotin(IV) complexes of bis-(2,6-di-tert-butylphenol)tin(IV) dichloride [(tert-Bu-)(2)(HO-Ph)](2)SnCl(2) (1) with the heterocyclic thioamides 2-mercapto-pyrimidine (PMTH), 2-mercapto-4-methyl-pyrimidine (MPMTH), 2-mercapto-pyridine (PYTH) and 2-mercapto-benzothiazole (MBZTH), of formulae {[(tert-Bu-)(2)(HO-Ph)](2)Sn(PMT)(2)} (2), {[(tert-Bu-)(2)(HO-Ph)](2)Sn(MPMT)(2)} (3), {[(tert-B...
Fiber Surface Modification Technology for Fiber-Optic Localized Surface Plasmon Resonance Biosensors
Considerable studies have been performed on the development of optical fiber sensors modified by gold nanoparticles based on the localized surface plasmon resonance (LSPR) technique. The current paper presents a new approach in fiber surface modification technology for biosensors. Star-shaped gold nanoparticles obtained through the seed-mediated solution growth method were found to self-assembl...
Photoluminiscent (PL) cellulose aerogels of variable shape containing homogeneously dispersed and surface-immobilized alloyed (ZnS)x(CuInS2)1-x/ZnS (core/shell) quantum dots (QD) have been obtained by (1) dissolution of hardwood prehydrolysis kraft pulp in the ionic liquid 1-hexyl-3-methyl-1H-imidazolium chloride, (2) addition of a homogenous dispersion of quantum dots in the same solvent, (3) ...
Three colorimetric reagents for the determination of formaldehyde, the Nash reagent (ammonia plus acetylacetone), Purpald (4-amino-3-hydrazino-5-mercapto-1,2,4-triazole), and N-methylbenzothiazolinone-2-hydrazone (MBTH), were compared for the determination of methanol when used in conjunction with alcohol oxidase. The combination of alcohol oxidase plus the commonly used Nash reagent was specif...
The morphology and anti bacterial activity of capped Silver Nanoparticles of 5-Methyl 2-mercapto benzimidazole prepared via chemical reduction is studied. Spherical shaped capped Ag-NPs with size of 40nm are obtained by treatment of aqueous silver ions with ethanolic solution of 5-Methyl 2-mercapto benzimidazole as capping agent .The synthesized nanoparticles are characterized by SEM, TEM, XRD,...
• Volatile thiols are responsible for the characteristic aroma of Sauvignon Blanc. There are 4 main volatile thiols: 4-mercapto-4-methylpentan-2-one (4MMP): box tree, broom 3-mercaptohexyl acetate (3MHA): passion fruit 4-mercapto-4-methylpentan-2-ol (4MMPOH): citrus zest 3-mercaptohexan-1-ol (3MH): grapefruit A comparative study of Sauvignon Blancs from around the world showed that those from M...
SUMMARY The protective action of mercaptoalkylamines has been examined. Anticipated protection against HN2 has been observed, l-mercapto-2-aminobutane being slightly more effective than cysteamine. Protection failed in the case of L-phenylalanine mustard and chloroquine mustard, but significant post-protection was obtained with Cytoxan. Results obtained with various combinations of intraperiton...
