Spinel ferrites gas sensors: a review of sensing parameters, mechanism and the effects of ion substitution
(Taylor & Francis, 2021-09)
There is an increasing demand of highly sensitive, stable and highly selective gas sensors to
detect toxic gases. This is inspired by the need to monitor the concentration of these gases
in order to guarantee humans, ...
Structural properties of high density polyethylene matrix composites reinforced with open air and furnace rice husks ash
(Journal of Chemical Engineering and Materials Science, 2021-12)
In this work, rice husks ash (RHA) was introduced to pure and recycled high density polyethylene
(HDPE) matrix, at varying ration (0-50%) to formulate rice husks ash High density polyethylene (RHAHDPE) composite. RHA was ...
Assessment of Selected Physico-Chemical Parameters of Groundwater in Chuka Igambang’ombe Constituency, Kenya
(Chuka University, 2022)
Groundwater is an essential source of water for drinking and other domestic uses. Recently, there
has been high dependence on groundwater due to water shortage as a result of changing climates,
and higher costs of accessing ...
Determination of precursors of acrylamide formation in roasted maize
(Advances in Phytochemistry, Textile and Renewable Energy Research for Industrial Growth – Nzila et al. (Eds), 2022-04)
Acrylamide, an organic compound with the formula CH2=CHCONH2, is a contaminant generated through high-temperature cooking processes as a result of Maillard reactions catalyzed by the presence of
reducing sugars and free ...
