4-Oxatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives as NMDA receptor- and VGCC blockers with neuroprotective potential
(MDPI, 2020)
The impact of excitotoxicity mediated by N-methyl-D-aspartate (NMDA) receptor
overactivation and voltage gated calcium channel (VGCC) depolarization is prominent among
the postulated processes involved in the development ...
A Two-Decade Anthropogenic and Biogenic Isoprene Emissions Study in a London Urban Background and a London Urban Traffic Site
(MDPI, 2018-10-03)
A relationship between isoprene and 1,3-butadiene mixing ratios was established to
separate the anthropogenic and biogenic fractions of the measured isoprene in London air in both
urban background (Eltham) and urban ...
Hyphenated LC-ICP-MS/ESI-MS identification of halogenated metabolites in South African marine ascidian extracts
(The South African Chemical Institute, 2018)
Extracts of 13 species of marine ascidian collected in Algoa Bay were analyzed by LC-ICP-MS/ESI-MS. This technique allows
parallel analysis of the molecular species and the presence of certain elements. The LC-ICP-MS/ESI-MS ...
Amorphous Pt@dCu/CNT catalyst for methanol elextrooxidation
(South African Chemical Institute (SACI), 2013)
A multi-walled carbon nanotube-supported, Pt decorated nano-sized amorphous PdCu alloy cores (denoted as Pt@PdCu/CNT)
catalyst with lower Pt loading is synthesized via a galvanic displacement reaction. The structure is ...
Atmospheric bromoform at Cape Point, South Africa: an initial fixed-point data set on the African continent
(EGU, 2018)
Bromoform mixing ratios in marine air were measured
at Cape Point Global Atmospheric Watch Station,
South Africa. This represents the first such bromoform data
set recorded at this location. Manual daily measurements
were ...
Acylphloroglucinol derivatives from the South African helichrysum niveum and their biological activities
(MDPI, 2015)
Abstract: Phytochemical investigation of aerial parts of Helichrysum niveum (H. niveum)
using different chromatographic methods including semi-preparative HPLC afforded three
new (1–3) and six known (4–10) acylphloroglucinols ...
Inhibition of oxidative stress and skin aging-related enzymes by prenylated chalcones and other flavonoids from helichrysum teretifolium
(MDPI, 2015)
Ten flavonoid-related structures viz. heliteretifolin (1), isoxanthohumol (2),
2',4',6'-trihydroxy-3'-prenylchalcone (3), isoglabranin (4), glabranin (5), 7-methoxyisoglabranin
(6), quercetin (7), 4'-methoxyquercetin ...
Silver/carbon codoped titanium dioxide photocatalyst for improved dye degradation under visible light
(Hindawi Publishing Corporation, 2017)
Herein, we report the synthesis of quartz supported TiO2 photocatalysts codoped with carbon and silver through the hydrolysis of titanium tetrachloride followed by calcination at 500°C. The prepared samples were characterized ...
Aptameric recognition-modulated electroactivity of poly(4-styrenesolfonic acid)-doped polyaniline films for single-shot detection of tetrodotoxin
(MDPI, 2015)
The work being reported is the first electrochemical sensor for tetrodotoxin
(TTX). It was developed on a glassy carbon electrodes (C) that was modified with
poly(4-styrenesolfonic acid)-doped polyaniline film (PANI/PSSA). ...
Effect of nanoparticle (Pd, Pd/Pt, Ni) deposition on high temperature hydrogenation of Ti-V alloys in gaseous flow containing CO
(Elsevier B.V., 2017)
The hydrogenation properties of Ti-V hydrides coated with nanoparticles have been studied in gaseous mixtures of argon and hydrogen with and without additions of 1% CO. Nanoparticles of Pd, Ni, and co-deposited Pd/Pt with ...
