By doing magnetization measurements during magnetic field sweeps on thin films of the new superconductor MgB2, it is found that in a low temperature and low field region small flux jumps are taking place. This effect strongly suppresses the central magnetization peak leading to reduced nominal superconducting critical current density at low temperatures. A borderline for this effect to occur is...

C3F7H (FM-200) has recently been introduced as an alternative for Halon 1301 (CF3Br) fire suppression agent. In this paper, as part of an effort to study the effects of C3F7H on high temperature ignition of gaseous fuels, we are expanding on our earlier evaluations of ignition inhibition characteristics of C3F7H. Of particular interest is a better or improved understanding of the fundamental me...

A temperature insensitive three-turn microfiber coil resonator (MCR) is demonstrated by embedding it in Teflon with opposite thermo-optic coefficient. The temperature dependence of a MCR strongly depends on the microfiber size which controls the ratio of thermal effect contributions from silica and polymer. Fabricated from a ~3μm-diameter microfiber, the temperature dependence of our MCR is com...

The pseudogap in the cuprate high-temperature superconductors was discovered as a suppression of the Knight shift and spin relaxation time measured in nuclear magnetic resonance (NMR) experiments. However, theoretical understanding of this suppression in terms of the magnetic susceptiblility of correlated itinerant fermion systems was so far lacking. Here we study the temperature and doping evo...

The timing of the suppression of gene 30 (deoxyribonucleic acid ligase) mutations by rII mutations was studied by temperature shift-down experiments with a temperature-sensitive rII mutation. The rII function must remain inactivated for about 5 to 8 min at 37 C for suppression to occur, thus making suppression an early function. This result is in agreement with the timing of expression of other...

The state-of-art Li-ion batteries have revolutionized the portable electronic industry and first-generation electric vehicles due to their high energy density at ambient temperatures. Owing catastrophic failures under heat, these power devices are incompatible for applications such as in defence arsenals, subsurface drilling, space exploration medical appliances, where performance high-temperat...
