Reduction of aldehydes and ketones to their corresponding alcohols in 1-butyl-3-methylimidazolium tetrafluoroborate.
(2017)The use and release of volatile organic solvents (VOS) to the atmosphere have become detrimental to both human health and his environment. In addition, the non-recyclability and the excessive consumption of these solvents ... -
Refractive effects in phase objects and associated phenomena.
(1994)The effect of the refraction of a laser beam propagating through three different phase objects, i.e. a laser produced plasma and two different gas media, is investigated in this thesis. It is shown that these effects ... -
Review of solar energy inclusion in Africa : a case study of Nigeria.
(2017)This work reviews solar energy inclusion in Africa using Nigeria as a case study. It reviewed studies made on viability, challenges and solutions associated with making solar energy a viable energy option in Nigeria. ... -
Rhenium(I) and -(V) complexes of N-donor heterocyclic chelates.
(2016)Abstract available in PDF file. -
Rhodium-catalyzed and uncatalyzed synthesis of boronate esters and their subsequent utility in the Suzuki realm.
(2008)This study has shown that alkythioboranes 1,3,2-dithiaborolane and 1,3,2-dithiaborinane, disproportionated significantly during their synthesis. Their interaction with 1-octene has been investigated, and the rate constants, ... -
A robust air refractometer for accurate compensation of the refractive index of air in everyday use.

A satellite and ground based study of fine structure in VLF whistlers.
(1992)The matched filtering technique for improving the spectral resolution of VLF whistlers, originally developed by Bhegin and Siredey (1964), has proven to be useful for extracting information about the magnetospheric plasma ... -
Scope of microporous and mesoporous molecular sieves in the oxidation of higher alkanes with ozone
(2008)Alkane-rich fractions including n-paraffins are the most important chemical feedstock used in the -
Screening of water pollutants using metallophthalocyanine-based chemically modified electrodes.
(2021)Abstract available in PDF. -
Seasonal analysis of water and sediment along the Umgeni River, South Africa.
(2014)Increased pollution caused by industrialization, urbanization, afforestation and agriculture has resulted in severe reductions to the health of rivers in South Africa. Numerous studies carried out on South African rivers ... -
Second Kerr-effect virial coefficients of non-dipolar molecules with axial and lower symmetry.
(2016)Abstract available in PDF file. -
Security and entanglement in differential-phase-shift quantum key distribution.
(2009)Quantum key distribution (QKD) aims at the creation of a secret key in the two locations of partners, traditionally Alice and Bob, wishing to communicate in private. A generic QKD protocol utilises a quantum channel and ... -
Security in quantum key distribution protocols.
(2013)Quantum theory forms one of the most studied theories of nature. It has inevitably led to a number of different research areas. One of the breakthroughs was the development of quantum cryptography which now forms one of ... -
Sedimentation and chemical processes on the Lower Mkuze floodplain : implications for wetland structure and function
(2008)The Mkuze Wetland System, situated in northern KwaZulu-Natal, is South Africa’s largest freshwater wetland area. The system plays a vital role in the functioning of the local landscape and has been identified as an important ...
