The present work deals with comparison of microwave assisted extraction to that of conventional solvent extraction for the extraction of rice bran oil (RBO); focusing on extraction yield and oil composition. Microwave assisted extraction act as a green process over other method and proved that it is effective method for extraction of oil. The investigation also focuses on the study of functiona...

A quantitative spot-test for the determination of metformin in pharmaceutical preparations using diffuse UV-visible reflectance is reported. The procedure is quite simple, involving in the formation of a metformin-nickel(II) complex on a glass filter membrane with a later measurement of the reflectance in the spectrophotometer using an integration sphere. The analytical results obtained with co...

background : due to rapid advances in modern technologies such as telecommunication technology, the world has witnessed an exponential growth in the use of digital handheld devices (e.g. smartphones and tablets). this drastic growth has resulted in increased global concerns about the safety of these devices. smartphones, tablets, laptops, and other digital screens emit high levels of short-wave...

Photocatalysis application in water treatment has been the object of many researchers worldwide recent decades. However, there are limited commercial applications due to low photon transfer efficiency, which create barriers leading challenges making process efficient and economically feasible. Fixed UV/visible light sources, generally located outside reactor or encapsulated quartz tube inside s...

There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

This study investigates nutritional value, amino acid profile, and total anthocyanin in pigmented rice as an antioxidant anti-diabetic agent. Six varieties were extracted using 0.1% HCl methanol, namely four red rice, one black white rice. Rice extract was used for proximate analysis profiling. Total measured identified by ultraviolet-visible (UV-Vis) spectrophotometer thin-layer chromatography...

The removal of sulfur compounds from petroleum is extremely necessary for industrial and environmental reasons. Sulfur in transportation fuels is a major air pollution source. In this work, the efficiency of nanostructured Ni-clinoptilolite adsorbent was investigated in the removal of sulfur from gas oil. For this purpose, the design of experiments was performed by selecting effective factors i...

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

Abstract Plants remain the most important source in many industrial, medical, and agricultural applications, due to their production of chemical compounds as represent secondary metabolites plants, similar those found pharmaceutical pesticides. The aim this study was determine phytochemical separation leaves Myrtus communis L. extract plant by using GC–Mass technique, role these biological redu...
