Poly ( N -isopropylacrylamide) (PNIPAM) is a famous representative of thermosensitive polymers. Thermosensitive polymers undergo phase transition with lower critical solution temperature. Commonly, their behavior linked to conformational collapse above certain This called Coil-Globule transition. In contrast, most other usually show inverse temperature behavior, i.e., an upper temperature, corr...

3,4-dihydropyrimidin-2(1h)-thiones were synthesized in the presence of ag nanoparticle/melamine sulfonic acid (msa) supported on silica gel. the reaction was carried out at 110 oc for 20 min under solvent free conditions. in all cases, the three component reaction proceeded smoothly to give the corresponding 3,4-dihydropyrimidin-2(1h)-thiones in moderate to good yield. we have found the best co...

A theoretical study using Density Functional Theory and classical Molecular Dynamics simulations for the of carbon nanomaterials in archetypical Menthol + Thymol Type V Natural Deep Eutectic Solvent is reported. The nanoscopic structure representative nanofluid analyzed considering confinement, adsorption solvation effects, as well consequences on diffusion properties through nano pores. Differ...

Escherichia coli K-12 strains are normally tolerant to n-hexane and susceptible to cyclohexane. Constitutive expression of marA of the multiple antibiotic resistance (mar) locus or of the soxS or robA gene product produced tolerance to cyclohexane. Inactivation of the mar locus or the robA locus, but not the soxRS locus, increased organic solvent susceptibility in the wild type and Mar mutants ...

Background: The objective of the present study was to investigate the combinative effect of ball milling and solvent displacement method on size reduction of Celecoxib particles. Celecoxib is a poorly water soluble cyclooxygenase 2 inhibitor which has a wide range of therapeutic applicability. Methods: Microparticles were developed via solvent displacement method followed by planetary ball mill...
