The incorporation of colloidal quantum dots (QDs) into ionic crystals of various salts (NaCl, KCl, KBr, etc.) is demonstrated. The resulting mixed crystals of various shapes and beautiful colors preserve the strong luminescence of the incorporated QDs. Moreover, the ionic salts appear to be very tight matrices, ensuring the protection of the QDs from the environment and as a result providing th...

Conversion of unsaturated fatty acids, FAMEs or triglycerides into the corresponding cyclic organic carbonates involves two reaction steps—double-bond epoxidation and CO2 insertion epoxide—that are generally conducted separately. We describe an assisted-tandem catalytic protocol able to carry out carbonation methyl oleate in one-pot without isolating epoxide intermediate. Methyl carbonate was o...

Density Functional theoretical calculations confirm the experimental observation that the low-temperature photolysis of (TPP)Fe(NO)(NO2) (as a KBr pellet) results in the generation of linkage isomers involving the axial NO and NO2 groups and suggest the possible formation of the double linkage isomer (TPP)Fe(ON)(ONO). The energy difference between the ground state (porphine)Fe(NO)(NO2) and the ...

Densities in molten KCl, RbCI, T1C1, KC1-T1C1 and RbCl -TlCl at various temperatures (t °C) were measured to within ±0.1% by iridium pyknometry. For the pure melts the results fit empirical equations of the form Q=a—bt . The molar volumes at the melting points were derived and tested against other melting-point data for thermodynamic consistency. In the mixtures the volumes deviate from additiv...

A novel nucleoside antibiotic, Sch 36605, has been isolated from the culture filtrate of a Streptomycete sp.;°. All the physico-chemical and spectroscopic data presented herein indicate this compoundis a new blasticidin compound. A second closely related component, Sch 36606, was isolated0 together with Sch 36605. This compoundhas been characterized and identified as leucylblasticidin S2). Sch ...

Potassium tribromide wrapped around polyethylene glycol ({K+PEG400}Br3-) was easily prepared by two step reaction of PEG400 with KBr followed by the addition of molecular bromine to give PEG embedded potassium tribromide as a dark viscous oil. The synthesized material was found to be an efficient, cost effective, environmentally benig...
