Abstract At present, biodiesel is known as an alternative fuel globally. It also that the purification of before consumption mandatory to comply with international standards. Commonly, using water washing generates a massive amount wastewater high content organic compounds can harm environment. Therefore, this study applied and tested waterless method, i.e., solvent-aided crystallization (SAC),...

Photocatalysis is one of the promising processes for developing greener fuels. This work compares a new liquid Cd-based diacetate and CdOx nanoparticles photo-desulfurization diesel. Various tools, including XRD, XPS, TEM, 1H&13C NMR, FTIR, reflectance, photoluminescence, were used characterizing materials. Different parameters, such as irradiation type, catalyst dosage, oxidizing agents, solve...

Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...

INTRODUCTION The success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. The aim of this study was to evaluate the efficacy of Mtwo R and ProTaper retreatment files in removing the Resilon/Epiphany system with or without chloroform during retreatment. MATERIALS AND METHODS Sixty distal roots of first mandibular molars were pr...

Inorganic phosphate is determined by a molybdenummethodby using atomic absorption spectrophotometry, on the basis of the observations of Berenblum & Chain (1938) and Zaugg & Knox (1966, 1967). The method permits analysis for calcium in the same sample and can detect 0.1 ,ug of P. The procedure given below is designed for automatic diluters and dispensers and uses 0.2ml of plasma. It is suitable...

In this work, we are motivated by the need to produce particles of well-controlled size, shape and morphology for general application in catalysis, environmental remediation, nanomedicine, pharmaceuticals, the development of new materials, and other fields. Moreover, our approaches are guided by the desire for continuous and scalable production, in contrast to the batch-wise processes typically...
