The positive ∆H values, indicative of endothermic reactions, carry profound implications, suggesting the occurrence of heat absorption and revealing insights into the energy requirements and sources necessary for these processes. This becomes particularly pertinent when considering the anticipated relevance ...
For instance, in order to use it as a detector to measure the thermal effect induced by the absorption of a single photon, one must synchronize the photon source and readout detector. The SNS Josephson junction can also be operated as a threshold detector when biased close to \(I_c\) ...
During the last twenty years, heat management applications involve many industrial developments in HF materials. Thermal conductivity can Conclusions We have reviewed the current understanding of the rheology of highly filled systems. The filler shape, particle size distribution, orientation of the filler...
Zeolites are a family of microporous crystalline materials, which, since the 1940s, have had an indispensable role in the chemical industry as catalysts, adsorbents and ion exchangers. Advances in synthetic methodologies and characterization techniques have enabled the fabrication of new zeolitic materials...
So far, most studies on nanofluids have been conducted in the field of thermo-engineering, where nanofluids are mainly used to improve the thermal properties of refrigerants. Kim et al. [7] were the first to use nanofluids to promote heat transfer in an absorption-type refrigeration system; ...
Abstract The ever-increasing demand for efficient and sustainable catalytic systems has prompted a surge in the exploration of transition metal nanoparticles as catalysts for various chemical reactions. Among these, copper-based nanoparticles have emerged as promising contenders, offering a viable alternative...
Radiative sky cooling reduces the temperature of a system by promoting heat exchange with the sky; its key advantage is that no input energy is required. We will review the origins of radiative sky cooling from ancient times to the modern day, and illustrate how the fundamental physics of radi...
Here, we demonstrated a prototype to detect the intrinsic thermal conductivity of the single-wall carbon nanotube (SWCNT) and verify the significant non-resonant optical absorption behavior on tiny nanotubes by integrating the nanotube and ice into a new core-shell design. In particular, a ...
EPR spectrometers measure the transition of the unpaired electrons to the higher energy state; this is called resonant absorption of microwave energy. The EPR spectrum is in the form of the first derivative of the absorption spectrum in which the x-axis represents the magnetic field strength in ...
