Methylene blue is a popular dye used in the batik industry; however, it potentially causes environmental problems view of residual MB content liquid waste, which difficult to naturally degrade. This study aimed synthesize Fe3O4-TD using tea dregs from household waste and its application as an adsorbent for methylene dye. The synthesis was carried out reverse co-precipitation method with water s...

= Abstract = Trace metals are components of urinary stones, though minute and exist also in normal urine. There have been many studies concerning the role of these materials in crystallization. In this experiment we examined the role of trace metals and the effect of interaction of trace metals and promotors in crystallization of calcium oxalate. We used the agarose gel model with 3 layered str...

Creating novel nanostructures is a primary step for high-performance analytical sensing. Herein, a new worm like nanostructure with Zinc Oxide-gold (ZnO/Au) hybrid was fabricated through an aqueous hydrothermal method, by doping Au-nanoparticle (AuNP) on the growing ZnO lattice. During ZnO growth, fine tuning the solution temperature expedites random curving of ZnO nanorods and forms nano-worms...

-Iron doped Tin Selenide nanoparticles have been prepared by aqueous solution method in double distilled water at room temperature. All the chemicals used for this were of Analytical Reagent grade and of 99.999 % purity. Structural confirmation and particle size estimation of prepared SnSeFe0.5 Nanoparticles had been reported from Xray diffractogram obtained by CuKα radiation of wavelength 1.54...

In this research, NiAl-LDH was synthesized using the coprecipitation method and modified with biochar graphite to produce NiAl-biochar NiAl-graphite composite materials. The adsorbent that has been is used for application of adsorption Fe(II) ions in aqueous solution. resulting material characterized by XRD (X-ray Diffraction) analysis, spectrophotometer FT-IR, BET analysis determine specific s...

The abundance of clay in the Merauke district has not been utilized optimally. This is due to a lack research and information about these clays. Clay one natural minerals from silica group whose particle size less than two micrometers many uses, including basic materials for manufacture ceramics, paper-making materials, adsorbents, assisting drilling, bleaching CPO. In this study, characterizat...

The various purification methods have been developed to improve the quality local salt, NaCl content > 94%. Bentonite is one of materials used as binder impurities in purification. purpose study was synthesis a modified bentonite using alkaline solution, which includes natrium hydroxide (NaOH) and potassium (KOH) with concentrations (1, 1.5, 2, 2.5 M) determined level Na+, Ca2+ Mg2+ metals A...

Morphological evolution and swelling were observed in the zinc phthalocyanine (ZnPc) layer on a quartz crystal microbalance (QCM) sensor treated with annealing. The morphology affects during analyte injection. effect can shorten QCM recovery time. ZnPc was deposited surface of polystyrene/QCM by evaporation technique. annealing process conducted for 1 h at 3 temperature variations: 100, 150, 22...

This study was conducted to assess and compare the crack-healing ability of conventional electrical sintered microwave Al2O3/x wt. % SiC (x = 5, 10, 15, 20) structural ceramic composites. The both specimens studied by introducing a crack ?100 µm length Vickers’s indentation conducting heat treatment at 1200°C for dwell time 1 h in air. flexural or bending strength sintered, cracked, crack-heale...

Four rice cultivars (SR-4, K-39, Mushq Budij, and Pigmented) grown in Kashmir were selected for starch extraction characterization. Rice starches observed physicochemical, functional properties, vitro digestibility studies estimation of their glycemic indices. Compositional analysis revealed that moisture, crude fat, ash, protein contents varied significantly (p ≤ 0.05) from 7.96 to 11.33, 0.15...
