Nypa palm seed husk is an underutilized raw material found in Niger Delta region of Nigeria. In this research, this material was utilized as a raw material for the production of activated carbon which was used as an absorbent for the treatment of simulated wastewater containing C...
In this article, the issue of determining the power factor maximums of SixGe1-x alloy with different compositions is investigated. This issue is discussed also for other thermoelectrics based on literature data. It is shown that for the values of the Seebeck coefficient in the in...
Soils are prone to pollution due to the influence of climate change, globalization and industrialization. Soil samples used in this research were collected from two different metal scrap dumpsites while the controls were taken 500m away from sampling sites all in Anambra state, N...
The construction industry is seeking alternative sustainable materials for construction due to the increased demand on the conventional construction materials. Investigations into environmentally friendly binders, most predominantly geopolymer, have intensified in the past few ye...
Optical properties of antimony selenide thin film synthesized for solar cell application via chemical bath deposition method (CBD) is presented in this research. Antimony trichloride and hydrogen selenide are the starting materials. The influence of varying concentration of Ethyl...
The production, security, sustainability, and affordability of energy are crucial factors in various industries and physical and chemical processes. To address environmental concerns and promote energy production, solid waste materials can serve as catalysts. This research specif...
Due to the weak tensile strength of traditional concrete, relatively few concrete direct tensile tests (DTT) have been carried out for a long time, and many specifications and standards do not provide detailed guidance on its operation process. It was not until the birth of steel...
The improper dumping, management and siting of refuse and mechanic sites have largely contributed to the contamination of soil by heavy metals. This study evaluates heavy metal fractionation in soil obtained from some mechanic shops and dump sites in Obio Akpor Local Government A...
Micro-arc oxidation technology of titanium alloy is an efficient, economical and environmentally friendly surface treatment method to improve the properties of titanium alloy. Various additives have been widely used in the industry to improve the properties of micro-arc oxidation...
As an important structural material in the 21st century, titanium and its alloy have the advantages of corrosion resistance, high melting point, small density, high specific strength, no magnetism and biocompatibility, but low surface hardness, poor wear resistance, large frictio...
