Instrumental techniques for characterization of molybdenum disulphide nanostructures
(Hindawi, 2020)The excellent chemical and physical properties of materials (nanomaterials) with dimensions of less than 100 nm (nanometers) resulted in researchers and industrialists to have great interest in their discovery and applications ... -
Intercomparison of the representations of the atmospheric chemistry of pre-industrial methane and ozone in earth system and other global chemistry-transport models
(Elsevier, 2021)An intercomparison has been set up to study the representation of the atmospheric chemistry of the pre-industrial troposphere in earth system and other global tropospheric chemistry-transport models. The intercomparison ... -
Investigating the background and local contribution of the oxidants in London and Bangkok
(Royal Society of Chemistry, 2021)Birth registration marks a child’s right to identity and is the first step to establishing citizenship and access to services. At the population level, birth registration data can inform effective programming and planning. ... -
Investigating the variation of benzene and 1,3 butadiene in the UK during 2000–2020
(MDPI, 2022)The concentrations of benzene and 1,3-butadiene in urban, suburban, and rural sites of the U.K. were investigated across 20 years (2000–2020) to assess the impacts of pollution control strategies. Given the known toxicity ... -
Investigation of biofuel as a potential renewable energy source
(MDPI, 2021)An accelerating global energy demand, paired with the harmful environmental effects of fossil fuels, has triggered the search for alternative, renewable energy sources. Biofuels are arguably a potential renewable energy ... -
Isolation and characterisation of cellulose nanocrystal obtained from sugarcane peel
(Rasayan Journal, 2020)This work was aimed at developing efficient and stable cellulose nanocrystal (CNC) from sugarcane peel, which has been of growing concern as a potential for various industrial applications and providing a solution to the ... -
Laboratory study on the mobility of major species in fly ash–brine co-disposal systems: up-flow percolation test
(Springer Verlag, 2013)Apart from the generation of fly ash, brine (hyper-saline wastewater) is also a waste material generated in South African power stations as a result of water re-use. These waste materials contain major species such as Al, ... -
Low-Cost feedstock conversion to biodiesel via ultrasound technology
(MDPI, 2009)Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable ... -
The low-redshift circumgalactic medium in SIMBA
(Oxford University Press, 2021-08)We examine the properties of the low-redshift circumgalactic medium (CGM) around star-forming and quenched galaxies in the SIMBA cosmological hydrodynamic simulations, focusing on comparing H I and metal line absorption ... -
