A novel Ag2O/TiO2-modified chitosan-based photocatalytic film with high adsorption and photocatalytic activity was synthesized under simulated solar irradiation, based upon the coupling of the synergistic catalytic technique of nano Ag2O/TiO2 and membrane separation. XRD, XPS, FESEM, and TEM characterization results illustrated that the Ag2O nanoparticles with a small size of 3–5 nm deposited o...

Pulmonary surfactant lowers surface tension in the lungs. Physiological studies indicate two key aspects of this function: that the surfactant film forms rapidly; and that when compressed by the shrinking alveolar area during exhalation, the film reduces surface tension to very low values. These observations suggest that surfactant vesicles adsorb quickly, and that during compression, the adsor...

The lipopolysaccharide of Erwinia carotovora was analyzed by quantitative sugar analysis, methylation analysis, and chromic oxide oxidation. This led to the following structure of the core oligosaccharide: (Formula; see text).

This paper addresses the challenge of bridging the semantic gap between the rich meaning users desire when they query to locate and browse media and the shallowness of media descriptions that can be computed in today’s content management systems. To facilitate high-level semantics-based content annotation and interpretation, we tackle the problem of automatic decomposition of motion pictures in...

We demonstrate that subwavelength scatterers can couple sunlight into guided modes in thin film Si and GaAs plasmonic solar cells whose back interface is coated with a corrugated metal film. Using numerical simulations, we find that incoupling of sunlight is remarkably insensitive to incident angle, and that the spectral features of the coupling efficiency originate from several different reson...

Based on the environmental condition, a shoe manufactured with different suitable materials has to provide optimum comfort and strength features by using high-quality leather parts. The aim of study is evaluate quality upper in Bangladesh. Ten types leather, made from cow hides goat skins, were collected footwear industries research was carried out approved methods analysis as per International...

Lubrication with ambient air is not quite generally applied. The best known application is the “foil bearing” in tape recording systems for audio, video and computer applications; where the gap height that is needed for effective lubrication may quite easily be attained. This air gap reduces tape friction and wear of tape and recording head substantially. On the other hand, though, the air gap ...

This paper is concerned with the field enhancement when an electromagnetic wave passes through subwavelength metallic gaps. We focus on a particular configuration when there is extreme scale difference between the wavelength of the incident wave, the thickness of metal films, and the size of gap apertures. Based upon a rigorous study of the perfect electrical conductor model for the transverse ...
