Benzophenone antenna-sensitised 1-acyl-7-nitroindolines show a significantly enhanced extent of photochemical cleavage in aqueous solution over their non-sensitised analogues and release the carboxylate derived from their 1-acyl group. The present work investigates length and functional group ef...

The Pd-catalyzed allylation of 3-acetyl-2-oxindoles with allyl alcohol is performed using 3 mol% of Pd(dba)2, rac-BINAP and BINOL phosphoric acid as catalytic mixture. This procedure allows the in situ synthesis of 3-allyl-2-oxindole by adding Triton B to the reaction mixture. The deacylative al...

A novel carbonate binder for utilization of CO2 was prepared with dehydration of waste hydrated cement paste. The effect of water-solid ratios (w/s) varying from 0.175 to 0.275 on carbonation properties of the carbonate binder was evaluated and its phase composition and microstructure before and...

Poly(trimethylene carbonate-co-2, 2′-dimethyltrimethylene carbonate) [P(TMC-co-DTC)] with a molecular weight of about 150 kDa and different copolymer composition were synthesized by ring opening copolymerization of trimethylene carbonate (TMC) and 2, 2′-dimethyltrimethylene carbonate (DTC), us...

Deep geological repository is considered the internationally accepted method for spent fuel (SF) disposal. In countries where salt, clay, tuff and granite are unavailable at geologically suitable area, other rock types may come into consideration. In Israel, carbonate rocks make up a significant...

The Amazon continental shelf hosted one of the world's largest mixed carbonate-siliciclastic platforms from the late Paleocene onwards - the Amapá carbonates. The platform architecture, however, remains poorly understood and causes and timing of the cessation of carbonate deposition are st...

The fate of subducted carbonates in the lower mantle and at the core-mantle boundary was modelled via experiments in the MgCO3-Fe0 system at 70–150 GPa and 800–2600 K in a laser-heated diamond anvil cell. Using in situ synchrotron X-ray diffraction and ex situ transmission electron microscopy ...

A renewed interest in fault damage zones is aimed at better understanding stress perturbation around faults, earthquake ground motions and fluid flow in the upper crust. In this study, we analyse fault/fracture systems at the outcrop and map scale and define displacement - thickness (D-T) scalin...

The stimulus properties of aminorex and analogues of 4-methylaminorex, namely (4S,5S)-4-methylaminorex, N-methyl-(4S,5S)-4-methylaminorex, and the regioisomeric (R)-and (S)-2-amino-4-phenyl-2-oxazoline (rexamino) were compared in rats trained to distinguish (S)-amphetamine (1 mg/kg) from saline....

Reactions of 4-alkylamino-2-phenyl-2-oxazolines 1 with isocyanates and isothiocyanates provide unprecedented efficient and regioselective heterocycle–heterocycle transformations. Compounds 1 reacted rapidly with tosyl isocyanate yielding directly 3-alkyl-4-benzamido-1-tosyl-2-imidazolidinones 4...

(+) (1S,2S)-2-Amino-1-phenyl-1,3-propanediol reacts with ortho-esters to form 4-hydroxymethyl-5-phenyl-1,3-oxazolines. Subsequent reaction of their toluenesulfonyl derivatives with diphenylphosphinolithium yields the N,P-ligands, (4S,5S)-2-R-4-diphenylphosphinomethyl-5-phenyl-1,3-oxazoline (R = ...

A green effervescence-assisted dispersive liquid-liquid microextraction based on phthalic acid as complexing agent and co-disperser performed in a narrow-bore tube has been developed for the extraction and preconcentration of zinc and cadmium from high volume of aqueous sample, followed by flame...

The aim of this study is to isolate phytosterol compounds from orange juice using ultrafiltration (UF) flat sheet membranes (supplied by Alfa Laval) with molecular weight cut-off (MWCO) values of 10 kDa fabricated from regenerated cellulose, polyethersulphone and fluoropolymer. A cross-flow filt...

We report on the recovery of a photodegraded organic molecule mediated by a biopolymer. Amplified spontaneous emission (ASE) from disperse orange 11 (DO11) dye-doped polylactic acid (PLA) was used to monitor photodegradation while the material was being damaged by a strong pump laser. The ASE si...

Functional behavior of anoxic–aerobic–anoxic microenvironment on azo dye (C.I. Acid black 10B) degradation was evaluated in a periodic discontinuous batch mode operation for 26 cycles. Dye removal efficiency and azo-reductase activity (30.50 ± 1 U) increased with each feeding event until 13th...

Adsorption of a diverse set of chemicals onto goethite was evaluated by column chromatography. The pH of the effluents was 4.7–5.2. Van der Waals forces dominate the exothermic adsorption of 8 nonpolar compounds (e.g., PAHs and chlorobenzenes). H-bonding is responsible for the adsorption of 32 ...

Chloro-functionalized azobenzenedicarboxylic acids were prepared and their 2D and 3D metal–organic frameworks (MOFs), namely {[Co(4,4′-Cl2abdc)(DMA)]·H2O}n (1), {[Cu(4,4′-Cl2abdc)(DMA)]·G}n (2), {[Zn(4,4′-Cl2abdc)(DMSO)]·H2O}n (3), {[Mn(3,3′-Cl2abdc)(DMA)]·0.5DMA}n (4) and {[Cu(3,3′-Cl...

A novel series of coumarin-lipoic acid conjugates were synthesized via cycloaddition click reaction to find out new multi-target-directed ligands (MTDLs) for treatment of Alzheimer's disease (AD). All of synthesized compounds were screened for neuroprotective and anti-cholinesterase activit...

Esters, acyloximes, amides and acid anhydrides have been prepared from the respective carboxylic acids, oximes, amines and alcohols by the use of the reagent combination BrCCl3-PPh3.
