Velocity and magnetic field fluctuations in the solar wind show evidence that non-linear turbulent dynamics are present in the interplanetary medium. The cascade of energy created by these turbulent processes may provide a mechanism for in situ heating of the solar wind plasma. We perform three studies analyzing the turbulent energy cascade at 1AU using 10 years of data from the Advanced Compos...

Branched nanostructures are of great interest because of their promising optical and electronic properties. For successful and reliable integration in applications such as photovoltaic devices, the thermal stability of the nanostructures is of major importance. Here the different domains (CdSe cores, CdS pods) of the heterogeneous octapods are shown to have different thermal stabilities, and he...

Heating rate during crystallization is known to affect the final texture obtained in lead zirconate titanate thin films. The transient/intermediate phases present in the thin film during perovskite phase nucleation have been suggested to cause this variation in texture with heating rate. To understand the interrelationship between the transient/intermediate phases and the texture in the final p...

Recent X-ray and optical observations of the Perseus cluster indicate that the viscous and conductive dissipation of sound waves is the mechanism responsible for heating the intracluster medium and thus balancing radiative cooling of cluster cores. We discuss this mechanism more generally and show how the specific heating and cooling rates vary with temperature and radius. It appears that the h...

An alternative method of rapid-cycle PCR for DNA amplification is demonstrated using electrolyte resistance for heating and temperature monitoring. The PCR amplification solution is electrically conductive and can be heated by passing an alternating current through the sample. The temperature of the solution is evaluated by monitoring its electrical resistance. Cooling is accomplished by forced...

Oxygen release from metal oxides at high temperatures is relevant to many thermally activated chemical processes, including chemical-looping combustion, solar thermochemical cycles and energetic thermite reactions. In this study, we evaluated the thermal decomposition of nanosized metal oxides under rapid heating (~10(5) K s(-1)) with time-resolved mass spectrometry. We found that the effective...

The shock heating of a laser-driven, direct-drive target can determine its stability by affecting Rayleigh-Taylor growth rates through target decompression and ablative stabilization. Measurements indicate that pulses that rise rapidly to 10(14) W/cm(2) produce shock-induced temperatures of approximately 25 eV, whereas more slowly rising pulses show less heating. Analysis of the observed target...
