The goal of this research is preparation, optimization and in-vitro evaluation of rifampin-loaded silica nanaoparticles in order to use in pulmonary drug delivery. Nanoparticles are exhaled because of thier small size, Preparation of nanoaggregates in micron-sized scale and re-disrpersion of them after the deposition in the lung is one approach in order to overcome this problem, which we used i...

BACKGROUND Spray-drying techniques are commonly utilized in the pharmaceutical, dairy, and animal feed industries for processing liquids into powders but have not been applied to human blood products. Spray-dried protein products are known to maintain stability during storage at room temperature. STUDY DESIGN AND METHODS Plasma units collected at the donor facility were shipped overnight at r...

Tanning is the process of converting raw skin and hides from different animals into a sustainable manageable material called leather. Leather making very long consists many chemical mechanical steps. The most important step whole leather tanning step, which performed commonly either by vegetable or mineral tanning. More than 85-90% chrome tanning, common type currently applied.

A sludge composite modifier SCM which comprises a mixture of three cementitious components was proposed for sludge drying and stabilization. Effect of SCM components on sludge moisture content was analyzed using uniform design and the optimum composition of SCM was determined by computer-aided modeling and optimization. To compare the drying effect of SCM, quicklime, and Portland cement, the ef...

1. Freezing: the product to be dried is put over shelves in a chamber and its temperature is lowered so that the water (or the other solvent) is frozen. Unfortunately, not all the solvent freezes forming ice crystals, but a certain amount (sometimes significant) remains bonded to the product and must be finally desorbed. In some cases the product (the drug and the excipients) does not crystalli...

Piper betle L., more commonly known as betel or local name of Sirih, belongs to the family Piperaceae. Previous researches had shown that the leaves of P. betle possess tremendous beneficial effects including antimicrobial, antioxidant, anti-diabetic, wound healing and gastro-protective properties. This is due to the present of the two bioactive component; propenylphenols; which is the Hydroxyc...

It is based on the experiments conducted for study of chromium removal and recovery from chrome tanning waste water of leather industry for chromium removal about 98.5% was achieved at pH 8.0 and at this pH reduction of COD is 61.5 % and percentage for removal of color from the wastewater of leather industry is 99.5% under applying the batch experimental condition. For this purpose, it is carri...

Carbonaceous porous materials derived from leather skin residues have been found to have excellent CO₂ adsorption properties, with interestingly high gas selectivities for CO₂ (α > 200 at a gas composition of 15% CO₂/85% N₂, 273K, 1 bar) and capacities (>2 mmol·g-1 at 273 K). Both CO₂ isotherms and the high heat of adsorption pointed to the presence of strong binding sites for CO₂ which may be ...
