Recent trends in legislation across the world are aimed toward reduction of levels sulfur fuel oils to less than 10 ppm (ultra low diesel, ULSD) due its toxic and environmental effects. Hydrodesulfurization (HDS) is current method used for desulfurization faces technical challenges, extreme conditions energy consumption necessary reach levels. Recently, ionic liquid (IL) technology has been proposed as a possible solution achieving ULSD. ILs represent new class “green” solvents that gaining...

Semiconductor-based photocatalysis is a probable approach to overcoming many pollution problems and eradicating toxic organic materials from wastewater. This research endeavor aimed explore the synergistic potential of different semiconductor nanocomposites for photocatalytic degradation pollutants in contaminated water. A facile hydrothermal was employed synthesize bismuth oxide cobalt ferrite nanoparticles their precursors—bismuth nitrate pentahydrate, ferric chloride hexahydrate...

The biologically transformed product of estradiol valerate, namely 3,7α-dihydroxyestra-1,3,5(10)-trien-17-one monohydrate, C18H22O3·H2O, has been investigated using UV-Vis, IR, 1H and 13C NMR spectroscopic techniques, as well by mass spectrometric analysis. Its crystal structure was determined single-crystal X-ray diffraction based on data collected at 100 K. refined the independent atom model (IAM) transferred electron-density parameters from ELMAM2 database. is stabilized a network...

Prednisolone acetate {systematic name: 2-[(8 S ,9 ,10 R ,13 ,14 ,17 )-11,17-dihydroxy-10,13-dimethyl-3-oxo-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3 H -cyclopenta[ a ]phenanthren-17-yl]-2-oxoethyl acetate}, is an ophthalmic drug that belongs to the class of corticosteroids. Its crystal structure was refined using classical independent atom model (IAM) and transferred multipolar ELMAM2 database. The results both refinements have been compared. refinement found be superior in terms...
