Reversible Phase‐Change‐Induced Transparency Switching and Dynamic Thermal Regulation Gel for Energy‐Efficient Smart Windows

open access: yesEcoEnergy, EarlyView.
The phase transition process imparts shape‐stable gels with the capability of reversible transparency modulation and temperature‐responsive heat storage and release. When applied to smart windows, this property ensures the maintenance of thermal energy within the human thermal comfort zone, thereby facilitating indoor energy conservation.

A flight experiment to determine GPS photochemical contamination accumulation rates [PDF]

open access: yes
It was recently suggested that photochemically deposited contamination, originating from volatiles outgassed by a spacecraft, may be responsible for the anomalous degradation in power seen on the GPS Block 1 vehicles.

Optimal Nanoparticle Size in SiO₂/Al₂O₃‐Water Nanofluids for Enhancing Intercooler Thermal Enhancement: A Conjugate Heat Transfer Study

open access: yesEnergy Science &Engineering, EarlyView.
The simulation shows that the comprehensive heat transfer effect of using nanofluids as cooling liquid is greater than 1.30 nm SiO2/water and 40 nmAl2O3/water nanofluids have the best heat transfer enhancement effect, while all nanofluids of 30 nm Al2O3/water have the best heat transfer enhancement effect.

Effects of Concentrations of Water‐Based MgO Nanofluid on Heat Transfer Performance in Shell‐and‐Tube Heat Exchanger

open access: yesEnergy Science &Engineering, EarlyView.
This figure shows the variation of the total heat transfer coefficient of a shell and tube heat exchanger with different concentrations of water‐based MgO nanofluids at different inlet flow rates. The results indicate that the total heat transfer coefficient increases with increasing flow velocity, and at different volume fraction settings, the ...

Desorption Kinetics of O and CO from Graphitic Carbon Surfaces [PDF]

open access: yes
The desorption of O/CO from graphitic carbon surfaces is investigated using a one-dimensional model describing the adsorbate interactions with the surface phonon bath. The kinetics of desorption are described through the solution of a master equation for
