The temperature-dependent exchange rate and signal coalescence in the 13C CPMAS NMR spectrum of a crystalline molecular gyroscope are exposed by specifically deuterating the overlapping static carbons.

Strain-engineering of two-dimensional (2D) transition metal dichalcogenides (TMDs) has great potential to alter their electronic and optical properties. Thus far, experimental studies of the straining effects in 2D TMDs primarily focused on the static property measurements at room temperature. However, low-temperature and temperature-dependence studies are essential in understanding the underly...

Thermal effects are becoming a limiting factor in high-performance circuit design due to the strong temperature-dependence of leakage power, circuit performance, IC package cost and reliability. Temperature-aware design tries to maximize performance under a given thermal envelope through various static and dynamic approaches. While existing interconnect reliability models assume a constant temp...

The performance of an irreversible heat engine operating between two thermal reservoirs with finite, temperatureindependent heat capacity is analyzed. For this purpose, a dynamic second-law efficiency is introduced and assumed to be constant. As the first-law efficiency increases from zero up to the Carnot limit, the common final temperature of the reservoirs interpolates between the arithmetic...

Whereas the static spin-susceptibility x5(T) of b and at-(BEDT-TTF)& at 5.7 tesla increases in a slow monotonic manner with temperature, xS(T) for the organic superconductor (BEDT-TTF)$Zu(SCN)2 displays a markedly structured temperature dependence. This gives evidence for two or more phase transitions in the metallic phase at temperatures near 100 K and 50 K, in addition to the onset of superco...

Screening of bovine rumen contents for heat-resistant and micro-aerophilic cellulose-degrading microorganisms was performed on carboxymethyl cellulose (CMC) plates at 37 °C-45 °C, and many isolates were found to produce reducing sugars under a static condition. Of those isolates, R8 and R15, which efficiently produced reducing sugars from CMC at a high temperature, were further examined. Taxono...

Introduction Focused ultrasound induced heating for use in thermal therapy requires reliable temperature control to assure safety and therapeutic accuracy. MR thermometry based on the proton resonance frequency shift (PRFS) [1] in combination with a proportional, integral, derivative (PID) feedback control [2] has been suggested as a precise solution for controlling high intensity focused ultra...

We discuss a novel approach, the point-to-set correlation functions, that allows to determine relevant static and dynamic length scales in glass-forming liquids. We find that static length scales increase monotonically when the temperature is lowered, whereas the measured dynamic length scale shows a maximum around the critical temperature of mode-coupling theory. We show that a similar non-mon...

We have carried out a microscopic study of the dynamic structure factor of liquid He across the normal-superfluid transition temperature using the path integral Monte Carlo method. The ill-posed problem of the inverse Laplace transform, from the imaginary-time intermediate scattering function to the dynamic response, is tackled by stochastic optimization. Our results show a quasiparticle peak a...
