After en bloc staining with 2% (w/v) aqueous uranyl acetate, dehydrated through a graded series of ethanol, and washed two times with 100% acetone, specimens were embedded in Spurr’s resin. Serial ultrathin sections of approximately 70 nm thickness were cut with a diamond knife on a ...
Water thermoporosimetry is based on the Gibbs–Thomson effect where water crystals located in porous structure require more energy to melt due to the pore surface energy. When approximated to perfect cylinders, the diameter of the pores can be calculated from their melting point on the basis of ...
dissolved in 2.25% Na-hydrogenphosphate buffer (pH 7.4). After washing in the same buffer (12 h), the specimens were postfixed for 4 h in 1% OsO4solution (same buffer) at room temperature and, following dehydration in a graded series of acetone, embedded in epoxide resin (Araldit, FLUKA...

Furthermore, the oxidized form of the ruthenium complex [Ru(dppbt)3] (dppbt = 2-diphenylphosphinobenzenethiolate) was shown to react as an electrophile with the enol tautomer of acetone to form a new CS bond [43]. This reaction closely models the first two steps of the sulfoxide synthase...
The crystal structure of [Os(COD)(CNBu t) 2(NH 2N:CMe 2) 2][BPh 4] 2·(Acetone) 2 ( 7) has been determined from three-dimensional X-ray counter data and refined to a final R (on F) of 0.090 based on 3014 reflections. The compound crystallizes in the monoclinic space group C2...
Clues to its desirable properties were sought from X-ray crystallography and NMR spectroscopic studies, which revealed it to be a conformationally-flexible macrocycle, adopting one major conformation in solvents like acetone and chloroform due to four stabilizing intramolecular backbone amide NH---OC hyd...
crystal structure & solid miscibility, and composition & electronic structure, respectively. With our highly comparable alloyed catalysts, we demonstrate activities greater than that of pure Pd even after lowering Pd content by half. Using density functional theory together with these experimental results...
