We describe not only fleeting assembly of photoisomerizable azobenzene-based palladium complexes into microstructured crystalline architectures but also their light-responsive functions. A transformation in the crystalline morphology from two-dimensional (2D) parallelogram-like sheets to three-dimensional (3D) cuboid- or rhombus-like structures was achieved by changing the solvent from tetrahyd...

Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...

Objective: To investigate the difference of chemical bonds between urethane dimethacrylate (UDMA) bonding agents with ethanol solvent and acetone on dentin collagen. Material Methods: This experimental comparison study used three groups: G1 (Control): UDMA collagen; G2: UDMA, collagen ethanol; G3: acetone. The groups were then pelleted analysed FTIR, peak value carbonyl absorption band from eac...

This study evaluated exposures among vehicle repair technicians to hexane, acetone, toluene, and total volatile organic compounds (VOCs). On randomly selected workdays, we observed a characteristic pattern of solvent use among 36 technicians employed in 10 repair shops, each of which used an aerosol solvent product. We obtained quantitative exposure measurements from a subset of nine technician...

In cross-coupling of biomass-derived acetone and alcohols contributing to the production carbon-elongated chemicals fuels, essential catalyst components are metal dispersion for alcohol dehydrogenation and, more importantly, basicity carbon–carbon coupling. Herein, we report potential co-precipitated praseodymia–zirconia solid solution (Pr2Zr2O7) as a support Cu conversion butanol into C7 C11 p...

Introduction: Effect of drying time and temperature of solvent evaporation were different in different studies. Therefore, the aim of this study was to investigate the appropriate drying temperature and time of solvent evaporation in the two adhesives of Etch and Rinse. Methods: Seventy-two sound third molars were collected. On the buccal surface of the crown, flat dentinal surfaces were crea...

Solvent-based separation method is presumably an efficient and environmentally beneficial approach for elimination of brominated flame retardants (BFRs) from waste electrical and electronic equipment (WEEE). The overall goal of this study was to evaluate possible effects of organic solvent on the behavior of BFRs during solvent-based processing of WEEE. We initiated a set of batch experiments f...
