Abstract: Titania is a semiconductor and photocatalyst that is also chemically inert. With its bandgap of 3.0, to activate the photocatalytic property of titania requires light of about 390 nm wavelength, which is in the ultra-violet, where sunlight is very low in intensity.

Abstract: An improved right angle thermocouple provides for constant pressure sensing tip contact achieved by means of a coiled and thus resiliently biased junction wire structure extending from the mounting base, preferably in the form of a circular loop of flattened ribbon shaped dissimilar metallic wires overlapped at a welded sensing tip. This sensing tip is protected by a spring biased protective shield of low thermal conductivity material having a few prongs extending from its open end for contact with the surface to be monitored in a manner that causes little thermal modification that would result in an erroneous temperature reading. The shield member, preferably cylindrical in shape, moves between two stops, one surrounding and protecting the sensing tip from physical damage and the other withdrawing just enough to permit the resilient bias of the sensing tip loop to establish a constant measurement contact pressure.
