Elevated exposure to Ultra-Violet Radiation (UVR) from the sun has led adverse effects on human skin and foods, therefore, need for materials that offer resistance (UV) penetration protection. Some building window non-window-materials, car-glasses, Linear Low Density Polyethylene (LLDPE) Terephthalate (PET) rubber plastic have been investigated determine their transparencies suitability use as shields against UVR. These were studied by directly measuring scattered solar radiation through...
Background. Elevated concentrations of heavy metals in soil have detrimental consequences on the environment, which translates into damaging effects humans. Objective. An evaluation was carried ...
This study investigated the pore characterization of polyurethane (PU) foam as a necessary step in water filtration membrane fabrication. Porous material is essential for predicting performance, strength, durability, surface feel, and to understand transport mechanisms using modeling simulations. Most existing techniques are relatively costly, time-consuming, subjective, have cumbersome sample preparations. focused on three inexpensive imaging systems: black box, Canon camera (EOS760D),...
Polymer products have been applied in all spheres of life and their disposal after use has a problem. In Ghana, non-biodegradable polymer the form used water-sachet bags is littered everywhere. Coconut husk, which natural fiber, also available as waste. We explore means recycling sachet-water coconut husk to yield useful product. A composite was formed by melting polyethylene, into dispersed then allowed set. Varied masses fiber were added water absorption test, hardness/compressive flexure...
Cataracts are the leading cause of blindness worldwide. Current methods for discriminating cataractous lenses from healthy Sprague-Dawley rats during preclinical studies based on either histopathological or clinical assessments which weakened by subjectivity. In this work, both and lens tissues were studied using multispectral imaging technique in combination with multivariate analysis. Multispectral images captured transmission, reflection scattering modes. all, five spectral bands found to...
Multi-spectral imaging (MSI) has made diagnosis of microscopic samples considerably easier and information abound. Most MSI systems use continuum light sources filters for purposes. However, these are relatively expensive, unstable due to extreme pressure temperature associated with prolong acquisition time. In this work, we present a metallurgical microscope retrofitted light-emitting diodes (LEDs) as illumination microscopy. This multispectral LED (MSLEDIM) is cheaper capable acquiring...
Color is essential for the fashion and art of fabrics, with its retention being a quality measure great significance brand user. The colorfastness some metallic fabrics has been established using absorption spectroscopy, by determining quantity dye that bled after undergoing wash laundry processes. Two ( X Y ) washing detergents (liquid powdered) were used. washed GyroWash machine set normal (40°C) hot (60°C) durations 60 min 90 min. There was repeat second wash. wastewater each (sample)...
Background: Breast milk contains various micronutrients which nourishes a baby with nutrition, and therefore the endorsement for exclusive breastfeeding during first six months after birth. Such micronutrients, if in excess, can have adverse effects on baby.
 Objective: The levels of seven breast obtained from 27 lactating mothers Cape Coast Metropolitan area been determined using Epithermal Neutron Activation Analysis (ENAA). This technique was used because it is suitable performing...
Well-water contaminated by microbial bacteria has been purified using LEDs radiating in the ultra-violet and visible spectral regions. The water sample was exposed to specially constructed chambers purification process carried on for 3 days. efficiency of determined a 445 nm diode laser induce fluorescence (LIF) monitoring coliform count (Total coliform, Fecal Escherichia coli) as well Total Heterotrophic Bacteria (THB). LIF peak intensities at 526 (Raman peak) dissolved organic matter...
DNA origami technology provides a versatile approach for the chemical assembly of gold nanostructures. In this study bottom-up self-assembly using in process has been successfully applied to arrange five AuNPs asymmetrically. The templates were modified have binding sites that extended with sticky ends facilitate attachment AuNPs. With help thiol chemistry, which covered complementary introduced on surfaces, we able attach nanoparticles designed sites. It was realized there slight...
This project was funded by The Directorate of Research, Innovation and Consultancy (DRIC) the Management University Cape Coast. It sponsored as a Group-led Research involving researchers from Department Physics during third call for proposals Support Grants (RSGs) in 2018 Abstract Table salt is essential life if it contains metal impurities, can affect people that consume it. Komenda Edina Eguafo Abrem municipality makes evaporating brine Benya Lagoon. lagoon known to be polluted due various...
Rapid monitoring of 5-Hydroxymethylfurfural (HMF) in honey remains a challenge. This work has demonstrated using 445 nm Laser-Induced Fluorescence spectroscopy technique to monitor honey’s HMF, detecting up ~40 mg/kg HMF with good accuracy.
Shelf life of bottled natural fruit juice (BNFJ) provides relevant information on quality and authenticity for consumer protection. However, existing techniques monitoring the shelf BNFJ are destructive time-consuming. We report using laser-induced autofluorescence (LIAF) spectroscopic technique in combination with multivariate analysis BNFJ. The LIAF spectra data were acquired nine (9) continuous days three batches samples purchased from a certified retailer. Deconvolution revealed...
Purpose: Soil water retention studies are important for evaluating soil quality and movement in soils. This study assesses the content capacity changes curve of sandy after using zeolite X, activated charcoal, rice husk ash as amendments. Design/Methodology/Approach: Sandy samples were collected from area, Keta District Ghana, a core borer pot experiment used to determine pressure head soil. One-way analysis variance (One-way ANOVA) was analyze data. Water analyses conducted COMSOL...
A new device named technology-plasmonics has recently emerged and can be used to manipulate light at the nano-scale level. Here, we report method of two-photon photopolymerization for rapid laser direct writing plasmonic components. The characterization these components is performed by a leakage radiation microscope, which same system construction as micro-fabrication except pattern. dielectric structures covered with gold proved very efficient excitation surface plasmon polaritons in this...
The amount of micronutrients in food is a key factor that determines the health status person. concentrations nine micronutrients, Sodium (Na), Magnesium (Mg), Chlorine (Cl), Potassium (K), Calcium (Ca), Vanadium (V), Manganese (Mn), Copper (Cu) and Iodine (I), polished Jasmine 85 rice, locally cultivated five rice farming areas Ghana (Afienya, Afife, Dawhenya, Ashaiman Aveyime), were determined using Neutron Activation Analysis. standard materials used as reference International Atomic...
