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 ...
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 ...
Potential broad spectrum inhibitors of the coronavirus 3CLpro: a virtual screening and structure-based drug design study
(MDPI, 2015)
Human coronaviruses represent a significant disease burden; however, there is currently no antiviral strategy to combat infection. The outbreak of severe acute respiratory syndrome (SARS) in 2003 and Middle East respiratory ...
On the design of smart parking networks in the smart cities: an optimal sensor placement model
(MDPI, 2015)
Smart parking is a typical IoT application that can benefit from advances in
sensor, actuator and RFID technologies to provide many services to its users and parking
owners of a smart city. This paper considers a smart ...
Bioaccumulation of total mercury in the earthworm Eisenia andrei
(SpringerOpen, 2016)
Earthworms are a major part of the total biomass of soil fauna and play a vital role
in soil maintenance. They process large amounts of plant and soil material and can
accumulate many pollutants that may be present in ...
