Characterization of composite material from the copolymerized polyphenolic matrix with treated cassava peels starch
Kariuki, Stephen W.; Wachira, Jackson M.; Kawira, Millien; Murithi, Genson L.; Marangu, Joseph M. (Heliyon, 2020-07)Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has ... -
Characterization of Local Nano-Heat Transfer Fluids for Solar Thermal Collection
Kawira, Millien (Hindawi, 2020-08)Performance of organic oils in solar thermal collection is limited due to their low thermal conductivity when they are compared to molten salt solutions. Extraction of organic oils from plants can be locally achieved. 'e ... -
Characterization of Prototype Formulated Particleboards from Agroindustrial Lignocellulose Biomass Bonded with Chemically Modified Cassava Peel Starch
Kariuki, Stephen Warui; Wachira, Jackson M.; Kawira, Millien; Murithi, Genson Leonard (Hindawi, 2019)Conventional methods of making particleboards utilize wood chips. +is has resulted in a decrease in the tree cover due to the increase in wood demand. +e effect has been climatic change. Wood is bound using phenol ... -
Crop residues used as lignocellulose materials for particleboards formulation
Kariuki, Stephen W.; Wachira, Jackson M.; Kawira, Millien; Murithi, Genson L. (Heliyon, 2020-09)Efforts to reduce pressure on use of wood in particleboard formulation have included the use of non-wood materials such as crop residues. Physical and mechanical properties are determined by the number of the hydroxyl (-OH) ... -
Formaldehyde Use and Alternative Biobased Binders for Particleboard Formulation: A Review
Kariuki, Stephen Warui; Wachira, Jackson M.; Kawira, Millien; Murithi, Genson Leonard (Hindawi, 2019-10)
