    Abstract: A resistance temperature detector (RTD) that uses a ceramic matrix composite (CMC), such as a silicon carbide fiber-reinforced silicon carbide matrix, as an active temperature sensing element, which can operate at temperatures greater than 1000° C. or even 1600° C. Conductive indium tin oxide or a single elemental metal such as platinum is deposited on a dielectric or insulating layer such as mullite or an environmental barrier coating (EBC) on the substrate. Openings in the layer allow etching of the CMC surface in order to make high quality ohmic contacts with the conductive material, either directly or through a silicide diffusion barrier such as ITO. The RTD can measure both temperature and strain of the CMC. The use of an EBC, which typically is deposited on the CMC by the manufacturer, as the insulating or dielectric layer can be extended to other devices such as strain gages and thermocouples that use the CMC as a sensing element. The EBC can be masked and etched to form the openings. A conductive EBC can be used as the silicide diffusion barrier.

    Abstract: Method and apparatus for detecting in impedance change in a transmission line, such as a line in a computer bus. A CMOS-compatible time domain reflectometer circuit comprising a comparator is embedded in one or more chips and connected to the transmission line. The circuit measures the impedance inhomogeneity pattern (IIP) of the transmission line prior to use, and then repeatedly measures the HP during operation of the transmission line to detect a change in IIP, without Interfering with data transfer through the transmission line. The present invention can detect and locate wire-tapping magnetic probing or snooping, and Trojan and cold boot attacks on interconnecting buses between computer chips or integrated circuits in a computer system, such as on external memory buses.

    Abstract: Methods and apparatuses for highly sensitive detection of analytes using redox reactions. A library of heat reactions of analytes of interest with a variety of catalysts at a variety of temperatures is prepared. An array of sensors with low thermal mass heating elements is prepared, depositing the same or different catalysts, such as metal oxide catalysts that have multiple oxidation states, on each heating element. The low thermal mass heating elements are preferably not in thermal contact with a substrate, or a low mass substrate is used. The array is exposed to a sample at various temperatures. The sign and magnitude of the heat effect of the redox reaction of compounds in the sample or their decomposition products with each catalyst is measured and compared with the library. The catalysts and temperatures are chosen so that the desired analytes have a unique pattern of heat effect signs and magnitudes when reacted with those catalysts at those temperatures. The resulting detector is highly selective and sensitive to the analytes of interest.

    Abstract: This work investigates the beneficial roles of lithium bis(trimethylsilyl) phosphate (LiTMSP) which may act as a novel bifunctional additive for lithium ion batteries, in particular, LiNi0.5Mn1.5O4 (LNMO)/graphite cells. The cycle performance of LNMO/graphite cells is significantly improved with incorporation of LiTMSP. Trimethylsilyl functional group therein can react with HF generated through hydrolysis of LiPF6 by residual water in electrolyte solution, followed by a decrease in the concentration of metal ions dissolution from the electrode. The generation of superior passivating surface film derived by LiTMSP on graphite electrode, suppressing further electrolyte reductive decomposition and deterioration/reformation caused by migrated metal ions, is confirmed. Furthermore, LiTMSP derived surface film is likely to have better lithium ions conductivity with a decrease in resistance of the graphite electrode, improving rate performance of cells. The HF scavenging and film-forming effects of LTMPS are responsible for the less polarization of cells enabling to improve cycle performance.
