Alicyclic segments upgrade hydrogen separation performance of intrinsically microporous polyimide membranes
Even with high permeability, insufficient selectivity of intrinsically microporous polyimides is a major obstacle for large-scale membrane-based separation applications. The present work proposes to increase hydrogen separation performance by incorporating deliberately chosen alicyclic segments into Troger's Base (TB)-based polyimide backbones via ...
Broadband infrared LEDs based on europium-to-terbium charge transfer luminescence
Published in Nature Communications
Broadband near-infrared (IR) light-emitting diodes (LEDs) are desirable for smart devices and bio-imaging applications, but the efficiency is limited by the phosphor materials. The authors report broadband emission in Eu-Tb co-doped CaS due to metal-to-metal charge transfer between dopants, and build a broadband near-IR LED with output surpassing t...
The role of vector trait variation in vector-borne disease dynamics
...
Many important endemic and emerging diseases are transmitted by vectorsthat are biting arthropods. The functional traits of vectors can affect pathogen transmission ratesdirectly andalso through their effect on vector population dynamics. Increasing empirical evidence shows that vector traits vary significantlyacross individuals, populations, and e...
Effects of Cr addition on Charpy impact energy in austenitic 0.45C-24Mn-(0,3,6)Cr steels
Effects of Cr addition (0,3, and 6 wt%) on Charpy impact properties of Fe-C-Mn-Cr-based steels were studied by conducting dynamic compression tests at room and cryogenic temperatures. At room temperature, deformation mechanisms of Charpy impacted specimens were observed as twinning induced plasticity (TWIP) without any transformation induced plasti...
Phytoplankton thermal responses adapt in the absence of hard thermodynamic constraints
To better predict how populations and communities respond to climatic temperature variation, it is necessary to understand how the shape of the response of fitness‐related rates to temperature evolves (the thermal performance curve). Currently, there is disagreement about the extent to which the evolution of thermal performance curves is constraine...
Database for the kinetics of the gas-phase atmospheric reactions of organic compounds
We present a digital, freely available, searchable, and evaluated compilation of rate coefficients for the gas-phase reactions of organic compounds with OH, Cl, and NO3 radicals and with O-3. Although other compilations of many of these data exist, many are out of date, most have limited scope, and all are difficult to search and to load completely...
New understandings of how dielectric properties of fruits and vegetables are affected by heat-induced dehydration: A rev...
Dielectric heating (DH) is an alternative to traditional conductive heating. Preservation of fruits and vegetables through drying based on DH is faster than conventional heating systems, needing less processing time, and delivering a better dehydrated product as well as reduced treatment costs. Dielectric properties (DPs) are significant physical q...

Ultrastrong duplex high-entropy alloy with 2 GPa cryogenic strength enabled by an accelerated martensitic transformation...
The existing deformation-induced martensitic transformation mostly focuses on overcoming the trade-off of cryogenic strength-ductility; however, an enhancement of cryogenic strength further is still challenging. We present a concept to yield a cryogenic strength of 2 GPa in a duplex V10Cr10Co30Fe50 alloy. We adopt a thermodynamic calculation to red...
