Heteroaromatic π-stacking engineered near-infrared absorption for highly stable near-zero transmittance electrochromic window

open access: yesNature Communications
Electrochromic (EC) devices based on structurally designable and color-tunable EC molecules can dynamically regulate light-heat transmittance via the charge-transfer mechanism, yet face challenges of limited near-infrared (NIR) absorption, long-term ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

Wideband and flat gain series erbium doped fiber amplifier using hybrid active fiber with backward pumping distribution technique

open access: yesResults in Physics, 2019
A modern wideband and flat gain erbium-doped fiber amplifier (EDFA) is suggested and accomplished, by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-erbium doped fiber (Zr-EDF) as a hybrid active fiber.
