Abstract-- The effect of carboxylic acid from Palm kernel oil (PKO) on carbon steel SAE 1045 in 1M hydrochloric acid (HCL) media by using weight loss technique for corrosion prevention. The inhibition efficiency of PKO was calculated using weight loss technique. Weight loss and corrosion rates of carbon steel decrease…
Candesartan is an angiotensin-receptor blocker (ARB) with very low bioavailability approximately 15% that can be improved by increasing its solubility and dissolution rate. The aim of this study is to enhance dissolution of candesartan as a model hydrophobic drug through application of liquisolid technology. It was fo…
Summary: Ag NPs were synthesized by the chemical reduction method and were optically characterized. The change in size of the nanoparticles and position of surface Plasmon resonance was studied as a function of concentration of different reactants by using UV-Visible spectroscopy. Red shift was observed in the positio…
Hydroethanolic extracts of leaves of Solanum scabrum and seeds of Cola verticillata were analysed for anticancer properties. A MTT assay was done to evaluate their antiproliferative properties after 24 and 48 h treatment with varying concentrations. qRT-PCR was used to evaluate the modulation of seven genes involved i…
Carbon with nanostructure, is a material that currently being developed in recent years. It is one of the unique materials, showing excellent and unique physical and chemical properties, including high electrical and thermal conductivities, high surface area, high mechanical strength, and chemically inert. Its interes…
In this paper, the nanocrystalline porous silicon (PS) is prepared by electrochemical etching of p-type silicon wafer at currents density 20 mA/cm 2 and with different etching times on the formation nano-sized pore array with a dimension of around few hundreds nanometric. The films were characterized by the measuremen…
Thin films of SnO2: Pd have been deposited on glass substrate at 450 0 C using an alcoholic precursor solution consisting of Tin (IV) Chloride (SnCl4.5H2O) and Palladium Chloride (PdCl2). The influence of increasing Pd concentration on the electrical and optical properties has been investigated. The minimum resistivit…
domain (3-13) x 10 -3 g/L. The morphology of the micellar aggregates is fundamentally influenced by the polymer chemical structure. If in the case of azobenzene and azo-5-crwon-15-ether groups it is possible to obtain 35-155 nm diameter individual micelles, for the azo-6-crown-18-ether group, only small aggregates wit…
Existing spent nuclear fuel (SF) and high active waste (HAW) management policies and practices worldwide are the result of past presumptions that sufficient reprocessing and/or disposal capacity would be available in the near term. Consequently, in the past many countries have developed specific solutions for differen…
Abstract: Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. Electrical conductivity of conducting polymers can be tuned from insulating to metallic through proper doping…
In this paper, the shells limited by two flat concentric circles are considered.Both families of coordinate lines are sinusoids. Their middle surfaces may be associated to the group of velaroidal type surfaces. Considered surfaces can find application in landscape architecture and also in design of some manufactured d…
Analysis concept of gaseous or liquid media using porous silicon multilayers with optical sensing is presented. The sensor consists of optical filter with λ/4 layers, fabricated by electrochemical etching in HF/ethanol. The optical system is tested with ampicillin and shows a linear dependence with increasing ampicill…
Radiation exposure and effective dose received by villagers residing at twenty villages belonging to Natural High Background Radiation Areas of coastal regions of Tamil Nadu were studied; five houses in each village were selected. The NHBRA villages were of similar construction pattern (brick wall-tiled roof, cement f…
The present study was aimed to improve the solubility of Poorly water soluble drug (pioglitazone HCl), by the solvent evaporation method in order to achieve increased dissolution rate, improved solubility, bioavailability and stability. The main purpose of this investigation was to increase the solubility and dissolut…
Recovered paper is a valuable raw material for paper industry and its significance has been increasing steadily over the last years. Unbleached spruce kraft pulp was used as virgin fibres and influence of beating on strength properties was investigated. The best properties of unbleached virgin spruce kraft pulp were a…
A bicatalytic system was prepared by the immobilization of alcohol oxidase enzyme and an alkylamine organocatalyst in distinct locations of mesoporous nanoparticles. The resulting nanocomposites were able to perform a sequence of oxidation and aldol coupling reactions, which transformed short chain alcohols into longe…
A comparative research on the mechanical properties and microstructural studies of locally produced and imported low-carbonsteels have been conducted. These low-carbon steels have played major roles in the building and fabrication industries in Ghana.Twodifferentbatches of samples (rebars) from local and foreign produ…
Abstract: The aggressive attack by sulphate ions is one of the main reasons for the potentially damaging of Portland cement mortars and concrete. So, an experimental work on multicomponent blended cement pastes from Ordinary Portland cement (OPC), granulated blast furnace slage (GBFS) and pulverized fuel ash (PFa) use…
The aim of the present study was to apply experimental design methodology in the development and optimization of sirolimus liposomes employing a modified ethanol injection method. Dipalmitoylphosphatidylcholine (DPPC) and cholesterol (Chol) as well as dioleoylphosphoethanolamine (DOPE) were utilized in the preparation…
Summary: A solvent-free environmentally benign synthesis of oleylamine capped silver nanoparticles is presented. Upon heating 10 equivalents of oleylamine and silver nitrate at 165°C for 30 min followed by a precipitation step using ethanol as the precipitant particles characterized by an Zaverage diameter of 63 nm we…
