In this study, we investigated urea glycerolysis over ZnAl2O4 catalysts that were prepared by using a citrate complex method and the influence of calcination temperatures on the surface properties of the prepared catalysts by varying the calcination temperature from 550 °C to 850 °C. As the reciprocal substitution between Al3+ and Zn2+ cations led to the formation of a disordered bulk ZnAl2O4 phase, different calcination temperatures strongly influenced the surface properties of the ZnAl2O4 catalysts, including oxygen vacancy. The increase in the calcination temperature from 550 °C to 650 °C d

Abstract:

Preparation of LiTaO3 was done using the sol-gel method which is also known as the wet chemical technique. Thermal analysis (TG-DSC) of LiTaO3 precursor was studied to determine an optimized heating temperature. LiTaO3 was heated at 550 °C with different sintering time of 12, 24, 48 and 72 h. The formation of pure LiTaO3 occurred during sintering time of 72 h which was confirmed using X-ray diffraction (XRD). The morphology of pure LiTaO3 was recorded using a Scanning Electron Microscope (SEM). Pure LiTaO3 can only be formed at a longer heating time in order to complete the oxidation process.

Abstract:

Soccer players often experience eccentric exercise-induced muscle damage given the physical demands of soccer match-play. Since long chain n-3 polyunsaturated fatty acids (n-3PUFA) enhance muscle sensitivity to protein supplementation, dietary supplementation with a combination of fish oil–derived n-3PUFA, protein, and carbohydrate may promote exercise recovery. This study examined the influence of adding n-3PUFA to a whey protein, leucine, and carbohydrate containing beverage over a six-week supplementation period on physiological markers of recovery measured over three days following eccentr

The XRD data demonstrated that the Co-doped Pb2Fe2O5 thin films consisted of Pb2Fe2O5 and PbO phases with a low amount of CoO and Co3O4 phases. The increase in the cobalt concentration in the Pb2Fe2

Abstract:

Urinary excretion of N-acetyl-beta-glucosaminidase (NAG) is an early marker of nephrotoxicity. NAG activity was assayed by the fluorimetric method of Leaback and Walker in 17 patients treated (22 courses) with carboplatin (CBDCA, 220–550 mg/m2) before infusion and 24, 48, 72 and 96 h after. Increased excretion of NAG, a sensitive index of renal tubular damage, was observed following 10 of the 22 courses. A transient increase in plasma creatinine and/or abnormal proteinuria was observed in 6 cases. Impaired renal function prior to therapv seems to be a predisposing factor to the nephrotoxicity.

Nowadays, NiTi shape memory alloy plays an important role in medical applications, especially in intervention devices such as Cardiovascular stent, Retriever stent, etc. This research aims to design and fabricate the self-expanding and self-centering Atrial Septal Defect (ASD) closure device from NiTi shape memory alloy wires. The device was made by braiding 72 NiTi wires and forming to double-disk shape. Heat-treatment was carried out at the temperature range between 510°C to 550°C for 30 min, respectively. DSC measurements and pull tests were done in order to evaluate the transformation and

Abstract:

Iron aluminides are considered as candidate materials for high temperature applications for their excellent high temperature corrosion and oxidation resistance. In the present work, iron-aluminide coatings were developed by friction surfacing (6351 aluminum alloy deposited on a low-carbon steel substrate) followed by a diffusion heat treatment. The initial coatings were found to be geometrically homogenous and adhered well to the steel substrate. The heat treatment process was carried out at 550 °C for 48, 72 and 96 h and the resulting coatings were characterized in terms of microstructure, ch

Abstract. Most plant-available Si in strongly desilicated soils is provided through litter decomposition and subsequent phytolith dissolution. The importance of silicon (Si) cycling in tropical soil–plant systems raised the question of whether oil-palm (Elaeis guineensis Jacq.) cultivation alters Si cycling. As oil palms are considered Si hyper-accumulators, we hypothesized that much Si is stored in the above-ground biomass of oil palms with time. Furthermore, the system might lose considerable amounts of Si every year through fruit-bunch harvest. To test these hypotheses, we analysed Si conce

In addition, the BHC/AgNW/THC TCFs exhibit a transmittance of 90.6% and a haze of 1% at 550 nm under a sheet resistance of 72 Ω/sq. Furthermore, highly enhanced long-term stability has been guaranteed by the HC layers due to their excellent gas barrier property. The amazing fact is

After heating at 550 °C for 4 hours, the nanoparticles were analyzed for their surface area and composition. Gunningite had a higher surface area of 61.5 m²/g, compared to Wurtzite’s 11.4 m²/g. Elemental analysis showed Gunningite contained 71% zinc, 21% oxygen, and 2% sulfur, while Wurtzite had 6

Additionally, the annealed films exhibited a more uniform, dense, and smooth surface microstructure than that of the as-deposited Si films.
