The performance of BiVO4 photoanodes, especially under front-side illumination, is limited by the modest charge transport properties BiVO4. Core/shell nanostructures consisting coated onto a conductive scaffold are promising route to improving BiVO4-based photoanodes. Here, we investigate photoanodes composed thin and uniform layers particles Sb-doped SnO2 (Sb:SnO2) nanotube arrays that were synthesized using sacrificial ZnO template with controllable length packing density. We demonstrate...
iBeacon, a novel beacon device aiming at proximity estimation was introduced in 2014 by Apple Inc. based on Bluetooth Low Energy (BLE) technology. iBeacon is utilized our work to establish an in-room newborns localization system hospitals. Since can broadcast signal every certain interval, we adopt instead of RFID for baby tracking. In this paper developed new application obtain the necessary data from and then derive path-loss model line-of-sight (LOS) situation environment account RSS...
iBeacon, a novel technique for proximity estimation, is utilized in our work to establish an intelligent in-room presence detection system. iBeacon kind of beacon device introduced 2014 by Apple Inc. based on Bluetooth Low Energy (BLE) technology. The signal can be broadcasted every certain interval. We collected data line-of-sight (LOS) situation environment, and then recognize according path-loss readings. Data other situations environments such as obstructed-line-of-sight (OLOS) outdoor...
We have investigated the superhydrophobic behavior of coatings polydimethylsiloxane (PDMS) and polystyrene (PS) on ZnO nanowire-arrays. PDMS produced a conformal coating nanowires due to high interfacial affinity between PDMS, resulting in large water contact angle 168.0° (compared 108.8° for planar surfaces) droplet roll-off angles that were too small measure. The superhydrophobicity these is among largest reported any polymeric coating. PS instead preferentially coated bases valleys low...
