Due to rapid industrialization, the demand for heavy metals is ever increasing, but the reserves of high-grade ores are diminishing. Therefore there is a need to explore alternative sources of heavy metals. Ore mine gangues ...

Organic-inorganic perovskite photovoltaics (PVs) have attracted a lot of attention as high- efficiency thin film PVs which are relatively cheap and easy to fabricate. Lead halide perovskites have shown a rapid rise in power ...

This research presents the design, construction, and analysis of the performance of a mixed-mode solar dryer for crops. A mixed-mode solar dryer utilizes direct solar radiation from the sun as well as input heat ducted ...

One of the unintended impacts of crude oil exploration is the pollution of agricultural land and aquatic resources when there is accidental oil spillage. The environmental effect of this has resulted in untold hardship to ...

This work is aimed at studying activated carbons as supercapacitor electrode materials derived from plant biomass waste materials. The activated carbon raw materials are sourced from coconut shell, pine cone and rice husk ...

Materials selection is done regarding to the availability, cost and performance of the candidates. In buildings, cement is the material that is widely used, even though it is releases co2 (estimated about 7% of the worldwide ...

Titanium alloy is popular in biomedical application owing to its low density, good biocompatibility (i.e. biological and chemical inertness) and excellent mechanical properties. Due to the high disparity between the implant ...

Topsoil stripping, drilling and blasting extraction, waste rock dumping, loading, and unloading, crushing and screening, and materials transport are among other activities involved in iron ore mining. These activities ...

This work studies the adsorption capacity of laterite and iron oxide nanoparticles for dissolved ions in solution and therefore its ability to reduce conductivity of mine waste effluent. Three laterite samples were prepared ...

The Luteinizing Hormone-releasing Hormone (LHRH); also known as a Gonadotropin-Releasing Hormone can be utilized for targeted therapy with cytotoxic analogs, in which prodigiosin is linked to the [D-Lys6] LHRH. Our studies ...
