Under UV-visible light irradiation, multiple synergetic promotion effects on the photocatalytic activity of TiO2 by gold deposition can be observed, and plasmonic Au/TiO2 shows great potential for photocatalytic solar conversion.

1. Irradiation with three short ultraviolet (UV) wave lengths, 226, 233, and 239 mmicro rapidly immobilizes Paramecium caudatum, the dosage required being smaller the shorter the wave length. 85 per cent of paramecia immobilized with wave length 226 mmicro recover completely. Recovery from immobilizing doses is less the longer the wave length. 2. Irradiation continued after immobilization kills...

Face Detection is the first step of facial recognition algorithms and has been widely researched in the visible spectrum. Current research has shown that thermal facial recognition is as accurate as the visible spectrum recognition algorithms. This paper presents three face detection algorithms in both long-wavelength infrared (LWIR) images and visible spectrum images. The paper compares the Vi...

The facial vascular network is highly characteristic to the individual, much like the way his fingerprint is. A non-obtrusive way to capture this information is through thermal imaging. The convective heat transfer effect from the flow of “hot” arterial blood in superficial vessels creates characteristic thermal imprints, which are at a gradient with the surrounding tissue. This casts sigmoid e...
