Due to the good photocatalytic activity, the TiO2@CNTs thin film is highly desirable to apply to the self-cleaning glass for green intelligent building. Here, the TiO2@CNTs thin film has been successfully achieved by polymer-assisted approach of an aqueous chemical solution method. The polymer, polyethylenimine, aims to combine the Ti4+ with CNTs for film formation of TiO2@CNTs. The resultant t...
The authors compared self-reported occupational exposures with a workplace-specific job exposure matrix (JEM) in a 2004 survey of Texas health-care professionals (n = 3,650), by asthma status. Sensitivity, specificity, chance-corrected (kappa) and chance-independent (phi) agreement, and associations of self-reported exposures with asthma were compared with those for the JEM. Among asthmatics, t...
The suppression of optical reflection from a surface is essential in many applications, ranging displays with reduced disturbance ambient light to high-efficiency photovoltaic cells and stable detection (LIDAR) systems. Traditionally, antireflection (AR) surfaces are made multilayer (ML) coatings that produce destructive interference beams reflected each interface. More advanced AR based on bio...
In many plant species sophisticated functions such as water repellence, reduction of particle adhesion and reduction of insect attachment are correlated to a hierarchically sculptured surface design. One prominent example is given by the hierarchically sculptured, self-cleaning surface of the lotus leave (Nelumbo nucifera). In plants hierarchy of surfaces is often realized by combining microstr...
