BACKGROUND One of the problems arising from available preparations for dry eye syndrome is the limited residence time of products on the ocular surface. In this paper, we look at an innovative new treatment for dry eye, tamarind seed polysaccharide (TSP). TSP possesses mucomimetic, mucoadhesive and pseudoplastic properties. The 'mucin-like' molecular structure of TSP is similar to corneal and c...

With the dramatic increased use of agricultural film, potential environmental risks associated with it have been receiving widespread attention. Biodegradable film (BF) is considered an alternative to conventional polyethylene (PF), but its feasibility replace PF needs be verified. Thus, we conducted a two-year field experiment in Loess Plateau region China, exploring effects residual biodegrad...

SPRAY drying dilute suspensions of bentonit ic montmoriltonite produces a powder tha t shows totally random orientation of the crystallites within a sample large enough to diffract X-rays. The powder is collected by an electrostatic precipitator and can be handled in the normal mounting processes without introducing preferred orientation. Electron micrographs show this powder to be composed on ...
