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...
The shrinkage of concrete is an important index for its durability. This paper mainly introduces the common shrinkage types of concrete and their mechanisms as well as the methods commonly used in engineering and experimentation to reduce concrete shrinkage.
The use of magnetic nanoparticles (MNPs) has gained popularity due to their small size, physico-chemical properties, and cost-effectiveness. When subjected to a magnetic field, MNPs can be used to selectively attach, manipulate, or transfer specific substances to a desired locati...
Toothpaste plays an important role in maintaining and improving oral health and aesthetics. Over time, toothpaste recipes have evolved from simple suspensions of broken eggshells or ashes to complex formulations containing up to twenty different chemicals. Toothpaste is designed...
Shelter is an integral part of human needs. It has been adjudged second to food in the ranking of human needs. However, the provision of shelter for the Nigerian populace remains low despite various policies and efforts from both governmental and private agencies to provide desir...
The demand for opacifiers in ceramic industries necessitates exploration into sustainable alternatives due to the expense and scarcity of traditional materials. Opacifiers are crucial in ceramic production, imparting opacity to glazes, and are often imported, increasing productio...
This study investigates the effect of various formulation variables on flexible polyurethane foam (FPU) of a density of 32 kg/m3. A detailed observatory analysis is performed to figure out the impacts of toluene di-isocyanate (TDI), water, surfactant, stannous octoate, and amine...
