The demand for sophisticated tools and approaches in heat management and control has triggered the fast development of fields that include conductive thermal metamaterials, nanophononics, and far-field and near-field radiative thermal management. In this
PURPOSE:To accurately evaluate the thermal time constant of many elements in a short time by modulating a semiconductor laser applied with a constant current bias to measure the value when the phase difference in the transmitting characteristic from the current input to the light output becomes ...
Thermal management for high-end portable devices requires actions in three primary areas: power management, thermal management in the traditional sense and battery management from a thermal perspective [38]. The majority of power-related thermal problems can be linked to these causes: (1) use of ...
which is referred to as positive thermal quenching1,2,3,4. This phenomenon has been frequently observed in most phosphors due to the vibration aggravation with temperature to promote the domination of nonradiative multiphonon transition probability (Fig.1a). Such a phenomenon greatly...
as well as on the time derivative of the change of measured temperature difference, ΔT/dt. Showing relations between thermal inertia and the termcp·ΔT/dt, where ΔTis the experimentally detected difference between the sample and reference temperatures, this concept has been justified in various...

I use a small table fan set to the low setting which helps cool my external hard drives, and at the same time the small amount of air that blows over the laptop also helps in cooling it off. It's a price you have to pay when wanting desktop power performance in a small enclosed ...
Reliability and Safety: Equipped with GS certification and a 3-year warranty, the TGA 1550C ensures reliability and safety in its operation, providing peace of mind for users in high-stakes applications. User-Friendly Operation: With a constant temperature time setting of 0~300min and an arbitr...
of the full-orbit phase curve observed by the Transiting Exoplanet Survey Satellite (TESS; seeMethods). We imposed a uniform prior on the mid-eclipse time and assumed a circular orbit. Those parameters were subsequently fixed when fitting the spectrophotometric bins (seeMethods). The maximum star...
Most of the existing thermal metamaterials are mainly based on metal, which makes their fabrication complex and time-consuming, and limits their flexibility. Here, we show a strategy to simplify the fabrication process, improve machining accuracy, and realize flexibility in thermal metasurfaces. Our ...
