Cross Reactive FET Array for Gas Mixture Detection

Conventional chemical sensor discriminates different analytes by rejecting the interference using selective decorations on the sensor body. A cross-reactive chemical sensor array discriminates different analytes by interpreting the collective sensor response using signal processing technique, and solves for the interference.

Processing Spinel-Less Thermal Barrier Coating Systems

This invention, intended for use in the processing of turbine engine blades’ thermal barrier coatings, is a two-step procedure used to produce a thermally grown oxide that is completely devoid of lifetime-limiting spinel oxides. Both steps take place at the same temperature used in present day bond coat pre-oxidation, utilize everyday gases, and can be performed serially in the same furnace, in a matter of hours. In step one, pre-oxidation of a bond-coated blade yields a thermally grown oxide (TGO) layer that contains a limited amount of spinel. In step two, all spinel is removed in situ. In an industrial-scale setup, the entire process would take place in less than 24 hours, including ramp times to and from the exposure temperature. Once blade specimens are cooled and removed from the furnace, they are then ready to be coated with the thermally protective yttria-stabilized zirconia (YSZ) layer, using industry-standard techniques. Due to the nature of the process, no new spinel is expected to grow at the critical TGO–YSZ interface for as long as the part operates in service, which means that the blade will be completely spinel-less for its entire usable lifetime. By eliminating all spinel-related failure mechanisms, this may result in longer blade lifetimes and therefore significant cost reduction.

Chemical-Sensitive Field-Effect Transistor

Conventional metal-oxide semiconductor field-effect transistor (MOSFET) technology consists of a source, drain, gate, and substrate. The chemical field-effect transistor (chemFET) is a type of a field-effect transistor acting as a chemical sensor, and is similar to MOSFET except for the gate structures. Modern industrial players seek higher-sensitivity technologies which are small, durable, efficient, and versatile. Further advances in these materials and structures could enable many new kinds of layered semiconductors and devices. To address need, researchers at the University of California, Berkeley, have developed chemical-sensitive field-effect transistor (CS-FET) platform technology. By exploiting selective thin films incorporated into the CS-FET, researchers have created chemical sensors with commercial promise in terms of chemical-versatility and low-power.
