Abstract: A fire mitigation device may comprise a mesh screen of interlocking wires, with the purpose of protecting against all of radiant heat, embers, and direct flame, each of which may be present during a wildfire event. The wire mesh screen may be pre-framed or cut from a roll. The wire mesh screen may be placed or fitted over vents or other orifices of a structure, wrapped around a structure or feature to “screen it in,” or placed in a free-standing manner around a feature or structure in order to protect it from damage due to wildfire.

Abstract: A rectifying junction (15) is formed in a conduction path provided in a material (1). A size of the material (1) is smaller than a threshold size in a first dimension, the threshold size being the size required for the material (1) to exhibit sufficient quantum confinement such that it forms a semiconductor. A surface of a first region (17) of the material (1) is arranged to decrease the bandgap of the material such that the first region is conducting. A surface of a second region (19) of the material (1) is arranged to preserve a bandgap such that the second region is semiconducting. The second region (19) is contiguous to the first region (17), such that a rectifying junction (15) is formed at a boundary (21) between the first region and the second region.

Abstract: A tunnel field effect transistor (100) comprises a source region (102), a drain region (104), and a channel region (106) formed of a single material, in particular a half-metal. The channel extends between the source region and the drain region. The channel region (106) and the drain region (104) are smaller than a threshold size in a first dimension. The threshold size is the size required for the material to exhibit sufficient quantum confinement such that a non-zero band gap results and the material becomes a semiconductor. The source region (102) is larger than this threshold size in the first dimension and is thus metallic.

Abstract: A simple and compact apparatus, and a method, for determining the characteristics of a number of fluids used in the truck and automotive industries including coolant, bio-diesel, gas-ethanol and diesel engine fluid (DEF). The apparatus includes a sample container providing optical paths of different lengths for making measurements on a sample. The dual path length design allows the apparatus to capture both NIR and UV spectral ranges. The qualitative and quantitative properties of the fluid under test are compared to test results under normal conditions or to the properties of unused fluid. Two light sources are used within a spectrometer with each source being associated with a different optical path length.

Abstract: A process for face finishing fabrics, and in particular fabrics containing filaments, to provide them with good aesthetic characteristics is described. In addition, fabrics made from filaments having aesthetic characteristics and surface effects similar to those of fabrics made from spun yarns are described. Also, items of napery made from filaments and having good surface effects and low pick and snag performance are described. The process involves pre-abrading a fabric, such as one made from filaments, and then subjecting it to a high energy fluid treatment process.

Abstract: Woven fabrics made from non-stretch yarns yet having high levels of stretch and recovery are described. The fabrics include at least about 50% of a synthetic fiber component, and are woven such that the warp and filling are approximately balanced by weight before warp contraction, with about 50% warp density or less. The fabrics are exposed to a cumulative dynamic tension in the warp direction of at least about 250 min-lb/linear ft, and are then finished to about 70-80% of their reed width at a temperature greater than or equal to the heat set temperature for the synthetic fiber component. The fabrics may also be exposed to a face finishing process and/or a fluid treatment process.

Abstract: In a method and apparatus for pulsed laser deposition, a target is eroded more uniformly by employing a two-stage laser scanning process. In a first stage, a pulsed laser strikes the target along an x/y scan pattern across the surface of the target while the target is rotationally fixed. In a second stage, the target is rotated by an incremental angle. These two stages are continuously repeated in sequence throughout the pulsed laser deposition process.

Abstract: A unit dose test device for a nucleic acid amplification reaction has the form of a elongate disposable test strip. The test strip includes a dual-chamber reaction vessel pre-loaded with nucleic acid amplification reaction reagents, and a plurality of wells for processing a reaction occurring in the reaction vessel.
