Commercial Raw Materials. Their Origin, Preparation, and Uses

The analysis of plant-based raw materials of unknown origin.

Chosen aspects of the safety of use of several herbs received from National Medicines Institute, which came from smuggling, have been examined. The analysis has been conducted in three different aspects: (1) Possibilities of contamination of plant-based raw materials by metals of heavy elements (As, Cd, Cu, Cr, Pb). (2) Conscious smuggling of intoxicating preparation or narcotics in plant-based...

A colloidoscope of colloid-based porous materials and their uses.

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The i...

Commercial Uses of Straw

Preparation of multifunctional coating materials and their applications

Sol-gel technique has been utilized for the fabrication of multifunctional inorganic-organic hybrid materials for specific applications. Synthesized methacrylic acid and benzoylacetone modified tin alkoxide precursors were used for the first time for the realization of directly UV-photopatternable antimony-doped tin dioxide coatings. These single-layered coatings have transmission values over 8...
