Comparative degradation of two highly consumed antihypertensives in water by sonochemical process. Determination of the reaction zone, primary degradation products and theoretical calculations on the oxidative process
(Elsevier, 2019)
This work compares the sonochemical degradation of losartan and valsartan (antihypertensives) in water. Initially, the suitable operational conditions of ultrasonic power density and frequency were established. Under such ...
New psychoactive substances in several European populations assessed by wastewater-based epidemiology
(Elsevier, 2021)
Wastewater-based epidemiology (WBE) can be a useful tool to face some of the existing challenges in monitoring the use of new psychoactive substances (NPS), as it can provide objective and updated infor- mation. This ...
First-Principles Study on Polymorphs of AgVO3: Assessing to Structural Stabilities and Pressure-Induced Transitions
(American Chemical Society, 2017-11)
In this paper, we present a comprehensive theoretical study, based on density-functional theory calculations, and which focuses on the structural and electronic properties of silver vanadium oxide (AgVO3) in the monoclinic ...
Extent of the influence of phosphate buffer and ionic liquids on the reduction of the silanol effect in a C18 stationary phase
(Elsevier, 2017-06)
The presence of anionic free silanols in the silica-based stationary phases gives rise to broad and asymmetrical peaks when cationic basic compounds are chromatographed using hydro-organic mobile phases. The addition to ...
Recent advances on ionic liquid uses in separation techniques
(Elsevier, 2017-09)
The molten organic salts with melting point below 100 °C, commonly called ionic liquids (ILs) have found numerous uses in separation sciences due to their exceptional properties as non molecular solvents, namely, a negligible ...
Mass spectrometric characterisation of a condensation product between porphobilinogen and indolyl-3-acryloylglycine in urine of patients with acute intermittent porphyria
(Wiley, 2015-07)
We document the presence of a previously unknown species in the urine of patients with acute intermittent porphyria (AIP). The compound was fully characterised by liquid chromatography tandem mass spectrometry. Interpretation ...
Selective reductive amination of aldehydes from nitro compounds catalyzed by molybdenum sulfide clusters
(Royal Society of Chemistry, 2017-07)
Secondary amines are selectively obtained from low value starting
materials using hydrogen and a non-noble metal-based catalyst.
The reductive amination of aldehydes from nitroarenes or nitroalkanes is efficiently catalyzed ...
Mechanism of Antibacterial Activity via Morphology Change of α-AgVO3: Theoretical and Experimental Insights
(American Chemical Society, 2017)
The electronic configuration, morphology, optical features, and antibacterial activity of metastable α-AgVO3 crystals have been discussed by a conciliation and association of the results acquired by experimental procedures ...
Computational Study of the Catalytic Mechanism of the Cruzain Cysteine Protease
(American Chemical Society, 2017)
Cysteine proteases of the papain family are involved in many diseases, making them attractive targets for developing drugs. In this paper, different catalytic mechanisms of cruzain cysteine protease have been studied on ...
Designing biocompatible and multicolorfluorescent hydroxyapatitenanoparticles for cell-imaging applications
(Elsevier, 2019)
In recent years, there has been a growing effort toward the synthesis, engineering and property tuning of biocompatible nanoparticles (NPs) that can be detected by confocal microscopy and then used as fluorescent probes. ...
