Abstract

This research was conducted to determine the morphology and composition of loose powder. This research used 3 types of MS Glow brand loose powder, namely natural, ivory and oily. Morphological characterization was carried out using a Scanning Electron Microscope (SEM), while composition was carried out using X-Ray Fluorescence (XRF). The morphology of the MS Glow brand loose powder of the ivory, Natural and Oily types is round in shape with the average particle size of each sample A, B and C, namely 62 nm, 48 nm and 47 nm so that it can be classified as nanoparticles. XRF test results show that all samples contain the elements Mg, Al, Si, K, Ti, Fe. All of these elements are contained in the composition of MS Glow brand loose powder. The XRF test also showed that all samples did not contain dangerous elements such as Lead (Pb), mercury (Hg) and Cadmium (Cd) and met BPOM standards.

Abstract

Solar radiation plays an important role in the desalination process due to its abundance in areas with potable water shortage and also occupies an important position in renewable energies due to simplicity of application. Still distiller is viewed by researchers as suitable source of potable water because of low cost of fabrication, easy operation and zero emission technology. Studies by researchers is geared towards exploring new models to enhance the efficiency of solar stills and increase the production rates. The main aspiration of this work is to experiment the effect of incorporating a passive condenser into a modified conventional solar still to enhance daily productivity rate. It has been found that modified passive still distiller coupled with external condenser gives about 11.85% higher production rate as compared to the modified conventional still distiller. Daily and accumulated distillate yield for the still distillers have been studied and analyzed. As a result of the findings, the researchers recommend the sawdust padding around still distillers can maximize productivity leading to efficient water distillation in regions where that require still distiller usage. This recommendation has desired result of enhancing access to potable water in areas with water scarcity and do contribute to sustainable and cost-effective water purification method.

Abstract

Energy is crucial to critical development of any nation. It is a major determinant of economy power. Unfortunately, fossil fuel which has served as a major means of energy remain unsustainable and has detrimental effect on the environment. Renewable source of energy such as biomass promising a better replacement since it is ecofriendly and sourced from unlimited feedstock. Briquette is one of the alternative sources of energy derived from biomass. It has the potency of replacing wood fuel with good heating value and substantial heating time. It is eco-friendly and sustainable. it is majorly produced from waste residue of agricultural process and production which make it more susceptible as an alternative source of heating energy in sub-Sahara Africa, especially, Nigeria which was referred to as agricultural nation. Nigeria has many crop residues including groundnut- shells and straw; rice- straw and husk, maize-Stalk, cob and husk; cassava- stalks and peelings, soybean- straw and pods, sugar cane-bagasse and tops/leaves, cotton-stalk, millet- straw, sorghum-straw, and cowpea's shell which could serve as a good raw material for briquette production. Despite the huge availability of feedstock, manpower and technical how, briquette formulation merely exists in the nation. The commercialization of briquette in the country has failed woefully. Thus, a need for comprehensive studies on the missing links on why briquette does not thrive like other Africa nations such as Uganda and Kenya. This study reviewed; challenges; implications and way out associated with briquette technology in Nigeria.

Abstract

This research is located in the PT BSPC area using the well logging method as the beginning of coal exploration activities. There are 7 well logging data with coal quality values in the form of moisture content, ash content and calorie data. From processing and interpretation using WellCAD 5.7 software, the lithology of the research area was obtained in the form of clay, coal, sandstone, carbonseous clay and coal. At 7 points, 9 coal seams were found, namely seams A11, A1, A, B11, B, B, C, D1 and D. The thickest seam is seam B with an average thickness of 5.85 m. From the correlation, the relationship of log density with proximate data had a fairly strong relationship except for the caloric value which had no correlation with the coal seam C in the study area. For the most influential correlation to the density value is the moisture content. The quality of seam B coal is better than seam C coal. On average, seam B has a calorie of 5531 cal/gr while seam C is lower at 5153 cal/gr. These two seams have a fairly high ash content, but seam B has a lower moisture content of 16.13% while seam C has a moisture content of 16.65%.

Abstract

Malt is the germination product of cereals that contain hydrolytic enzymes capable of breaking down starch. The concentration of rice grain malt is a factor that affects the hydrolysis process of rice (Oryza sativa L.) and the characteristics of the resulting rice sugar syrup. The malt concentrations used in this study were 25%, 35%, 45%, 55%, and 65%. The rice sugar syrup showed positive (+) results for residual starch. The concentration of rice grain malt had a significant effect on total soluble solids, color, organoleptic ranking, and viscosity. The total soluble solids of the rice sugar syrup ranged from 41.95 to 64.95 °Brix. The color difference (ΔE) ranged from 33.410 to 12.648. The viscosity of the rice sugar syrup ranged from 244.8 to 1448.1 cPs. The organoleptic ranking showed that the syrup produced with 65% malt concentration had the highest sweetness level. Hedonic organoleptic scores for color ranged from 3.6 to 3.36, aroma from 3.48 to 3.92, taste from 3.48 to 4.00, viscosity from 3.32 to 4.00, and overall acceptance from 3.56 to 4.16. The rice grain malt concentration of 65%, which was the highest concentration used for rice hydrolysis, produced rice sugar syrup with total soluble solids of 64.95 °Brix, color difference (ΔE) of 12.648, viscosity of 1448.1 cPs, the highest sweetness ranking, and the best favorability.

Abstract

Metal-organic frameworks (MOFs) have emerged as highly promising materials for gas sorption and separation, owing to their extensive surface areas, customizable pore sizes, and diverse structural properties. This study delves into the mechanisms of gas sorption, strategies for gas separation, and synthesis methodologies of MOFs, with a particular focus on (M=Al, Zn) with aminoterephthalate. The synthesis of these MOFs involves the reaction of metallic salts with 2-amino-terephthalic acid under mild solvothermal conditions, using an ethanol and water solvent mixture. The synthesized MOFs samples were characterized using techniques such as FTIR, SEM, EDX, XRD, BET, and TGA to determine functional groups, surface morphology, elemental analysis, molecular structure, pore sizes, surface areas, and thermal stability respectively. The findings underscore the potential of MOFs such as Zn-amino terephthalate exhibits high CO2 uptake capacities at low temperature while at high temperature reduces the affinity for CO2 and adsorbed CH4 higher compared to Al-amino terephthalate, at various temperatures range (30°C, 60°C, and 100°C) and 1.0 bar pressure of the findings are consistent across various studies.

Abstract

Conventional uses of sodium bicarbonate in food processing result in gastrointestinal (GI) upset with such symptoms as nausea, stomach diarrhea, and vomiting to the venerable. Plant ash from empty palm bunch which is readily available, economical, underutilized, nutrient dense, and a tenderizer without side effects becomes the best alternative. Sorted and 12 h steeped soybean was sprouted (72 h) on a jute bag spread on the floor and covered with black polythene. The sprouts and un-sprouted soybeans were boiled (20 min) in water extract of plant ash of concentrations 30, 50, 70% and 0.5% sodium bicarbonate separately and hand de-hulled after cooling. The hulls were removed by water floatation and their cotyledons were milled with 93oC water (1 kg in 2.7 L) in variable kitchen blender, sieved with double layer calico cloth and the soymilk boiled for 20 min in open pan with continuous steering. The soymilk samples were separately analyzed. The results showed that with decrease in plant ash concentration, moisture, fiber, ash, fat, energy, pH, viscosity and appearance of soymilk from sprouted soybean increased more than their un-sprouted counterparts. Also, soymilk from sprouted soybean boiled in 0.5% sodium bicarbonate increased more than the un-sprouted counterparts in protein, vitamin C, calcium, phosphorous, iron, total soluble solids, pH, vitamin A and B1. There was no significant (p>0.05) in the acceptability of the entire soymilk samples, but those from sprouted soybeans were slightly better with more nutrient improvement at low ash concentration levels.
