Carbon nanostructures (CNS) were synthesized by the electric arc plasma chemical method during evaporation of a high-quality graphite electrode brand “fine-grained dense graphite” (FGDG-7) filled with catalyst (Pt), which was evaporated in helium environment. In synthesis process, following synthesized: multi-walled (MWCNT) and single-walled carbon nanotubes (SWCNT), fullerenes, graphene packet...

Synthesis of mixed gadolinium calcium heptamolybdate (GdCaHM) system in silica gel medium using single gel single tube technique has been successfully achieved. The grown crystal exhibits various morphologies, which includes spherulites, multifaceted, and square platelets. The nature of the grown material was established by X-ray diffraction (XRD) studies. Fourier transform infrared spectroscop...

Cellulose, chitin and chitosan are the most abundant biopolymer on earth and constitute an important class of biodegradable materials. The decomposition of three major biopolymers viz. chitin, chitosan and cellulose are studied using simultaneous thermal analysis i.e. thermogravimetry/differential thermal analyzer (TG/DTA). Thermal analysis is performed from ambient temperature to 700 °C in a f...

Different ancient mortar samples of Pamplona Cathedral have been analyzed to characterize their binder and aggregate fractions. A complete characterization has been carried out including chemical (complete macrochemical analysis, analysis of the soluble fraction in hot HCl (1:5) and of the insoluble residue, trace elements and soluble salts, using traditional chemical procedures, ion chromatogr...

Dolutegravir (DTG; S/GSK1349572) is a potent HIV-1 integrase inhibitor with a distinct resistance profile and a once-daily dose regimen that does not require pharmacokinetic boosting. This work investigated the in vitro drug transport and metabolism of DTG and assessed the potential for clinical drug-drug interactions. DTG is a substrate for the efflux transporters P-glycoprotein (Pgp) and huma...

The effect of γ-radiation dosage on the thermal stability cross-linked acrylic polymer "Carbomer-140" (СRB) was investigated. DTA, TGA, and DTG curves show multistage processes occurring in different temperature ranges heating CRB from 25 °C to 500 °C. rates decomposition were determined 40–110 °C, 180–260 260–330 330–500 In combination with results electronic structure calculations, potential ...

DTG are designed to share some of the advantages of TAG while overcoming some of its limitations. DTG involve two composition operations called subsertion and sisteradjunction. The most distinctive feature of DTG is that, unlike TAG, there is complete uniformity in the way that the two DTG operations relate lexical items: subsertion always corresponds to complementation and sister-adjunction to...
