While the introduction of large, bulky substituents such as tert-butyl, –SiMe3 or –Si(isopropyl)3 has been used recently to control the solid state structures and charge mobility of organic semiconductors, this crystal engineering strategy is usually avoided in molecular metals where a maximized overlap is thought for. In order to investigate such steric effects in single component conductors, ...

The aim of this study was to compare the bacterial load of unclipped gluteal skin in dairy cows following either no treatment or treatment with a standard 70% isopropyl alcohol-based skin treatment protocol. Twenty Holstein-Friesian dairy cows from a commercial dairy herd in Cambridgeshire, England, were used in this randomised, blinded, controlled study. On each of the experimental cows an are...

AIM To compare the antimicrobial activity of the chemical substances--70% isopropyl alcohol, 2% glutaraldehyde (GTA) and 0.25% peracetic acid (PAA) in disinfecting orthodontic pliers contaminated in vitro with Streptococcui mutani, Staphylococci aureui and Candida albicani. MATERIALS AND METHODS Distal end cutter pliers were divided into five groups: group 1 (negative control--sterilized plie...

Abstract: Novel ether thionocarbamates, O-butoxy isopropyl-N-ethoxycarbonyl thionocarbamate (BIPECTC) and O-(2-butoxy-1-methylethoxy) isopropyl-N-ethoxycarbonyl thionocarbamate (BMIPECTC), were synthesized in this study. Their collecting efficiencies in the flotation of chalcopyrite were investigated using flotation tests, adsorption measurements, ultraviolet spectra (UV) and Fourier transform-...

In the title compound, C13H18O3, the benzene ring is almost perpendicular to the acet-oxy plane, making a dihedral angle of 89.33 (11)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming a zigzag chain along the c-axis direction.

In the title compound, C20H25NO2, the cyclo-hexyl ring adopts a slightly disordered chair conformation. The dihedral angle between the mean planes of the quinoline ring and the carboxyl-ate group is 22.2 (6)°. In the crystal, weak C-H⋯N inter-actions make chains along [010].

In the title mol-ecule, C(22)H(35)O(2)P, the two cyclo-hexyl rings exhibit chair conformations. In the crystal, mol-ecules related by translation along the b axis are linked by the weak inter-molecular C-H⋯O hydrogen bonds.
