Peptide-Based Molecular Hydrogels as Supramolecular Protein Mimics
(Wiley, 2017-01-23)
This Minireview concerns recent advances in the design, synthesis, and application of low molecular-weight peptidic hydrogelators. The sequence-specific combinations of amino acid side chain functionalities combined with ...
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 ...
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 ...
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 ...
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 ...
Detection of Methyl Orange in Saffron and Other Edibles Using Direct Injection Micellar Liquid Chromatography
(Springer, 2017-01)
A simple, sensitive, rapid and eco friendly micellar
liquid chromatographic method was developed for the detec-
tion of banned color methyl orange in counterfeit saffron and
prepared foodstuffs. Methyl orange ...
International snapshot of new psychoactive substance use: Case study of eight countries over the 2019/2020 new year period
(Elsevier, 2021-02-03)
There is considerable concern around the use of new psychoactive substances (NPS), but still little is known about how much they are really consumed. Analysis by forensics laboratories of seized drugs and post-mortem samples ...
Joint Theoretical and Experimental Study on the La Doping Process in In2O3: Phase Transition and Electrocatalytic Activity
(American Chemical Society, 2019-08)
In2O3 and La3+-doped In2O3 nanostructures were synthesized through a facile and fast chemical route based on the microwave-assisted hydrothermal method combined with rapid thermal treatment in a microwave oven. The presence ...
El análisis de aguas residuales con fines epidemiológicos: presente y futuro en España
(Asociación Española de Estudio en Drogodependencias, AESED, 2020)
El análisis de aguas residuales con fines epidemiológicos es actualmente una herramienta fiable y comple-mentaria a las metodologías basadas en indicadores tradicionales para el control de diferentes sustancias entre las ...
Half-width plots, a simple tool to predict peak shape, reveal column kinetics and characterise chromatographic columns in liquid chromatography: State of the art and new results
(Elsevier, 2013-11)
Peak profiles in chromatography are characterised by their height, position, width and asymmetry; the two latter depend on the values of the left and right peak half-widths. Simple correlations have been found between the ...
