COVID-19 outbreak has rapidly disseminated across the globe, with severe consequences on humanity. Personal protective polymeric materials (PPPM) or personal protective equipments (PPE) are effective barrier protection against bodily fluid penetration and is compulsory for medical personnel to wear during medication of highly contagious COVID-19 patients in varying hospital wards across the globe to ensure protection against contraction. Nanotechnology (NT) advancements in textiles have avail...
2-D nanomaterials (NM) including graphene as well as transitional metallic dichalcogenides exhibit great prospects to enlarge the scope of materials utilized by the military. Specifically, they demonstrate importance in electrical energy storage uses. Due to sheet-like architectures and elevated electronic dissipation, 2-D NM can utilize efficient techniques of energy storage for defense applications. Emerging from medium (vehicles) towards miniature electronic sizes, gadgets such as batterie...
ABSTRACT Current advancement in raw material utilization is gradually changing from the conventional petro-based materials into natural materials in order to arrest environmental pollution issue which arises as a result of the non-biodegradability of products obtained from petro-based resources. Plant oil among other alternatives due to its abundance, relatively low cost, non-toxicity and biodegradable nature have been found to be a potential replacement for petro-based feedstock in many in...
Abstract The manufacture of plastic bags (HDPE, LDPE, LLDPE) is one of the leading industries in the world and has a strong consumer demand for packaging and packaging. The research examined the design of the film machine by analyzing the model of the bag blowing machine. Since the emergence of the rough and the formation of the balloon focus on the cooling area when the formation of the balloon and to make the roll to be ready for the stage of cutting (finished product). And compared this a...
Research on the single pot green synthesis of silver nanoparticles (AgNPs) was done using aqueous medicinal plant extract of Tithonia diversifolia and Acalypha wilkesiana. Characterization was carried out by spectroscopic techniques. Experimental optimization studies and the antimicrobial activity of the nanoparticles were investigated. Bottom-up approach was applied for the synthesis of both Tithonia diversifolia silver nanoparticles (TD-AgNPs) and Acalypha wilkesia silver nanoparticles (AW-...
ABSTRACT Some mechanical properties of water melon rind and pawpaw peel reinforced Low density polyethylene (LDPE) and Linear Low Density, (LLDPE) composites have been studied. Two sets of filler loaded LDPE and LLDPE composites were prepared using the injection moulding techniques at a processing temperature of 1900C Dispersing agent, silicon oil, was added to the composite as a plasticizer to improve flow, processability and to reduce the brittleness of the product. A comprehensive ...
ABSTRACT Optimum working condition for the FUTO fabricated extruder was established. The effect of screw speed on the viscoelastic property (die swell), sensory characteristic (hardness) and mechanical properties (modulus, ultimate strength and %elongation at break) of NNPC Polyolefin blends (HDPE/PP) were investigated. Screw speed had no effect on the mechanical properties of the unblended samples. Lower speed was found to favour co-blending of HDPE and PP. Maximization of tensile mo...
ABSTRACT This thesis presents the findings of the investigation on the effects of some printing variables on the colour yield of reactive dye printed cotton fabric. The main print variables investigated are squeegee strokes, print paste viscosity, paste storage time and superimposed print. The printing pastes, (pastes A, B and C) used in this work were prepared using cassava starch, NaCl, NaOH and Procion reactive dye (Procion M); and were of different viscosities. The printing operation ...
