Effect of Alkyl Chain Length on the Bandgap, Ferroelectric, and Photoelectric Properties of Lead‐Based Molecular Ferroelectrics

Advanced Science, EarlyView.
This study develops a novel 2D molecular ferroelectric [C6N2H18]PbI4 with polarization enhanced photovoltaics. It systematically investigates the effect of alkylamine spacer cation chain lengths on the band gap, ferroelectric, and photoelectric properties, offering new design strategies.

Thermoelectric-cooled terahertz quantum cascade lasers

Optics Express, 2019
We demonstrate the first lasing emission of a thermo-electrically cooled terahertz quantum cascade laser (THz QCL). A high temperature three-well THz QCL emitting at 3.8 THz is mounted to a novel five-stage thermoelectric cooler reaching a temperature difference of ΔT = 124 K.

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

Advanced Science, EarlyView.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.

Volcano‐Inspired Dual‐Carbon Network Aerogel for High‐Performance Solar Evaporation With Edge‐Directed Salt Crystallization and Recovery

Advanced Science, EarlyView.
A volcano‐inspired dual‐carbon aerogel featuring hierarchical conduits and an outer carbon‐fiber shell directs rapid water transport, confines heat, and enables directional salt migration. Radial temperature gradients in the conical structure trigger Marangoni‐driven edge‐localized salt crystallization while maintaining an unobstructed photothermal ...

A Wood Plasticine With Controlled Phase‐Change Behavior and Malleability for Energy‐Closed‐Loop and Conformally Adaptive Thermal Management

Advanced Science, EarlyView.
A photothermal wood plasticine exhibiting controlled phase‐change behavior and malleable property is developed. The developed wood plasticine can provide all‐day, on‐demand, and low‐loss solar heating for geometrically diverse objects, including thermoelectric generator, human body, and battery, through its controlled crystallization‐melting ...

Experimental Investigation of Using Thermoelectric Coolers under Different Cooling Methods as An Alternative Air Conditioning System for Car Cabin

Automotive Experiences
The cabin car temperature will increase when parked in direct sunlight, so the energy required to cool cabin space by the air conditioner will be higher. This study aims to investigate using a thermoelectric cooling system as an alternative to a chiller
