Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

Deep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Inverting Singlet and Triplet Excited States using Strong Light-Matter Coupling

, 2019
In organic microcavities, hybrid light-matter states can form with energies that differ from the bare molecular excitation energies by nearly 1 eV. A timely question, given recent advances in the development of thermally activated delayed fluorescence ...

Thermochromic Radiative Cooling Coatings with Robust Superhydrophobicity for Energy‐Efficient Buildings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Statistical properties of chaotic microcavities in small and large opening cases

, 2019
We study the crossover behavior of statistical properties of eigenvalues in a chaotic microcavity with different refractive indices. The level spacing distributions change from Wigner to Poisson distributions as the refractive index of a microcavity ...

Solution processed optical modulated silver nanowire top electrode for high performance semi‐transparent organic solar cells

FlexMat, EarlyView.
Abstract Silver nanowire (AgNW) top electrodes are pivotal candidates for solution‐processed, semi‐transparent organic solar cells (ST‐OPVs). However, their light utilization efficiency (LUE) typically lags behind that of devices using evaporated metal electrodes, primarily due to the lack of effective optical modulation strategies compatible with ...
