The influence of temperature on the indentation size effect is explored experimentally. Copper is indented on a custom-built high-temperature nanoindenter, at temperatures between ambient and 200 0C, in an inert atmosphere that precludes oxidation. Over this range of temperatures, the size effect is reduced considerably, suggesting that thermal activation plays a major role in determining the l...

Understanding the temperature-dependent nanofluidic transport behavior is critical for developing thermomechanical nanodevices. By using non-equilibrium molecular dynamics simulations, the thermally responsive transport resistance of liquids in model carbon nanotubes is explored as a function of the nanopore size, the transport rate, and the liquid properties. Both the effective shear stress an...

Structural disorder appears to relate to the useful physical properties of ferroelectrics and relaxors. One such material is PZN, PbZn1/3Nb2/3O3. To explore what aspects of the disorder are specific to the polarised state, the temperature dependence of diffuse scattering in PZN has been investigated. Data were collected using both neutron and X-ray single crystal experiments in a range of tempe...

The NADPH-dependent reduction of rat hepatic microsomal cytochrome P-450 has been studied as a function of temperature. In the temperature range 4-37’ the reduction reaction was found to be biphasic and composed of two concurrent first order processes. This phenomenon was observed with microsornes from untreated and phenobarbital-induced animals in the presence or absence of exogenous Type I su...

Protein crystals usually grow at a preferable temperature which is however not known for a new protein. This paper reports a new approach for determination of favorable crystallization temperature, which can be adopted to facilitate the crystallization screening process. By taking advantage of the correlation between the temperature dependence of the second virial coefficient (B(22)) and the so...

The hydrophobicities of the 20 common amino acids are reflected in their tendencies to appear in interior positions in globular proteins and in deeply buried positions of membrane proteins. To determine whether these relationships might also have been valid in the warm surroundings where life may have originated, we examined the effect of temperature on the hydrophobicities of the amino acids a...

Circular double-stranded DNA has different topological states which are defined by their linking numbers. Equilibrium distribution of linking numbers can be obtained by closing a linear DNA into a circle by ligase. Using Monte Carlo simulation, we predict the temperature dependence of the linking number distribution of small circular DNAs. Our predictions are based on flexible defect excitation...

Time-resolved pump–probe transmission measurements were used to determine the temperature dependence of carrier lifetime for InN epilayers with unintentionally doped levels from 10 to 10 cm. The observed decay time at 20 K is well explained by a dominating radiative interband recombination, while at room temperature it is attributed to a defect related nonradiative recombination channel. The te...

We compare the temperature dependent characteristics of multiple quantum well semiconductor laser diodes and light emitting diodes operating at a wavelength, /z = 1.3 ,um. No model in which Auger recombination is the dominant temperature sensitive parameter can explain our experimental observations. We suggest that net gain is the appropriate temperature dependent variable which determines lase...

Poly resistors around the device can be used to perform fast in situ heating on a single device on wafer level. This is a commonly used technique to apply time-saving NBTI stress in the production line [Muth W, Walter W. Bias temperature instability assessment of nand p-channel MOS transistors using a polysilicon resistive heated scribe lane test structure. Microelectron Reliab 2004;44(8):1251–...
