Selective detection of vapor phase hydrogen peroxide with phthalocyanine chemiresistors.
The use of hydrogen peroxide as a precursor to improvised explosives has made its detection a topic of critical importance. Chemiresistor arrays comprised of 50 nm thick films of metallophthalocyanines (MPcs) are redox selective vapor sensors of hydrogen peroxide. Hydrogen peroxide is shown to decrease currents in cobalt phthalocyanine sensors while it increases currents in nickel, copper, and ...
متن کاملBuffer Cache Management for Low Power Consumption
As the computing environment moves to the wireless and handheld system, the power efficiency is getting more important. That is the case especially in the embedded hand-held system and the power consumed by the memory system takes the second largest portion in overall. To save energy consumed in the memory system we can utilize low power mode of SDRAM. In the case of RDRAM, nap mode consumes le...

متن کاملComparative gas sensing in cobalt, nickel, copper, zinc, and metal-free phthalocyanine chemiresistors.
The sensitivities of metallophthalocyanine (MPcs: M = Co, Ni, Cu, Zn, and H(2)) chemiresistors to vapor phase electron donors were examined using 50 nm MPc films deposited on interdigitated electrodes. Sensor responses were measured as changes in current at constant voltage. Analytes were chosen to span a broad range of Lewis base and hydrogen bond base strengths. The MPc sensor responses were ...
متن کاملScan Based Circuits with Low Power Consumption
In this paper we present a low power scan design method. Nowadays the Boundary Scan (BS) diagnostic access to the circuit input and output cells combined with a scan chain of concatenated internal flip-flops (FF) has become to be a standard. An alternative parallel diagnostic access method called Random Access Scan (RAS) is not used in nowadays ICs because of more difficult routability. In spit...
