The making of soap using vegetable matter (palm bunch waste) was examined. All the factors that impact blackish on the soap products after saponification process were studied with a view to remedying them. The remedial process involved subjecting the dried palm bunch matter to total combustion, soaking, filtering and…

For the first time, aniline was doped into the precursors used for preparing Li3V2(PO4)3, leading to a polyanilne (PANI)-doped Li3V2(PO4)3. In this work, three samples, having the weight content of aniline 5 wt%, 7 wt% and 10wt%, respectively, were fabricated. The as-prepared samples were characterized by XRD, SEM, an…
Nowadays, more attention is being paid to sustainability in construction. Over the years, the concrete research community has developed a wide range of potential ‘green’ concretes. To reduce cement related CO2 emissions, a considerable part of the traditional binder can be replaced with industrial by-products. However…
Abstract For InAs/GaAs(001) quantum dot (QD) system, the wetting layer (WL) evolution and its temperature dependence were studied using reflectance difference spectroscopy and were analyzed with a rate equation model. WL thicknesses showed a monotonic increase at relatively low growth temperatures but showed an initia…

A solid-liquid duplex casting process was applied to achieve simultaneous refinement and modification of sili- con phases in hypereutectic Al-Si alloys. In this process P-treated Al-24Si (wt%) solid alloy is mixed with Sr-treated eutectic Al-12.6Si molten alloy to provide an Al-18Si alloy in the Liquid ? Primary Si ph…
This paper reports part of the documentation being assembled by ONDRAF/NIRAS to support the safety assessment of the near-surface disposal of short-lived low and intermediate level waste (LILW-SL) or category A waste at Dessel, Belgium. The aim of this study was to establish a sorption database of critical radionuclid…
It is found that the fat extracted from mango seed kernel is edible and is rich in stearic and oleic acid, which could be used as surfactant hydrophobe for the synthesis of bio-surfactants. This article describes downstream processing of mango kernel fat (MKF) to isolate its fatty acid fractions. Further the unsaturat…
In the McMurdo Dry Valleys of Antarctica, stream biota is limited by the brief availability of liquid water. The benthic microbial mats harbor diatoms that have adapted to hydrologic stresses, including numerous endemic species. We found a strong relationship between diatom community composition and flow intermittency…
A number of nanosized advanced materials have been synthesized for photocatalysis using different techniques. These catalysts find applications in environmental remediation, sterilization, hydrogen production and renewable energy. Nanophotocatalyst has been used successfully for the treatment of hazardous materials su…
In order to study the influence of electrolyte solution on the value of soil pH, it was investigated the relationship between pH in water (pHH2O) and pH in 0.01 M CaCl2 (pHCaCl2) or 1 M KCl (pHKCl) electrolyte solution, for 94 samples from Iasi City, Romania. The pH values in salt solutions are lower than those in wat…
To obtain initial information on the possible repeated-dose oral toxicity of fullerene C60, Crl:CD(SD) rats were administered fullerene C60 by gavage once daily at 0 (vehicle: corn oil), 1, 10, 100, or 1,000 mg/kg/day for 29 days, followed by a 14-day recovery period. No deaths occurred in any groups, and there were n…
Analytical explicit solutions are presented for the use of square wave voltammetry (SWV) at disc microelectrodes to study two-electron reversible redox processes. This combines the advantages of SWV (minimization of capacitative effects, peak-shaped response and quick experiments) with those of microelectrodes (reduct…
OBJECTIVE: The study examined the difference in the incidence of symptomatic cerebral vasospasm with magnesium supplementation in aneurysmal subarachnoid hemorrhage (SAH) in a Korean population. METHODS: This retrospective analysis was performed in 157 patients diagnosed with aneurysmal SAH from January 2007 to Decemb…
New compounds of perphenazine and fumaric acid in 2 : 1 and 1 : 2 molar ratios have been prepared by solvent evaporation with the aim of increasing the drug solubility. Their physico-chemical properties were thoroughly characterized by differential scanning calorimetry, powder X-ray diffraction, Fourier infrared spect…
Hybrid nanomaterials comprising tungsten heteropolyacid (HPW) and iron-based MOF Basolite™ F 300 used as a support were obtained by post-synthesis combination of the two components. Samples with increasing HPW loading (20, 50, and 80 wt%) were characterised by appropriate physicochemical methods, including nitrogen so…
Over the years, several strategies have been developed for generating highly polarized nuclear spin systems, including dynamic nuclear polarization, optical pumping, and methods exploiting parahydrogen. Here, we present an alternative strategy, using an enhanced 'brute-force' approach (i.e. exposure to low temperature…
CdTe solar cells with back contacts formed by either (i) 15nm Cu evaporation followed by application of carbon conductive paste embedded with micron sized Cu particles in ZnTe powder and (ii) only with the above mentioned conducting paste, were evaluated. A Cu-related deep level defect with an activation energy of E a…
In this study, a new system of integrated photocatalytic adsorbents (IPCAs), three-dimensional wormhole-like mesoporous titanosilicate/reduced graphene oxide layered composites, were prepared with various Ti/Si ratios. The reduced graphene oxide (RGO) nanosheets played the role of giant two-dimensional (2D) platforms…
