Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Integrated Flue‐Gas Heat Recovery for Optimized Steam and Power Generation Using Organic Rankine Cycle (ORC): A Technical and Economic Assessment

Energy Science &Engineering, EarlyView.
Integration of a steam cycle with an existing gas turbine increased efficiency from 32% to 51%, reducing fuel consumption by 21.4% and CO2 emissions by 18.6%. The modification generated USD 13.9 million annual savings and lowered the Levelized Cost of Energy to 38.7 USD/MWh, with a 3‐year payback.

A trade‐off between efficiency and stability in a class of sky‐blue organic light‐emitting diodes

FlexMat, EarlyView.
OLED efficiency and stability are correlated with device structure using combined experimental and simulation approach. Efficient, but less stable devices suffer mainly from exciton‐exciton annihilation, while their opposites have excitons predominantly quenched by polarons.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Synergetic defect passivation of high‐quality 1.83 eV perovskite for efficient flexible perovskite/organic tandem photovoltaics

InfoMat, EarlyView.
This study proposes an ionic additive, (R)‐(+)‐tetrahydro‐3‐furanmethanol p‐toluenesulfonate (T3FpT) salt, featuring rationally designed cations and anions that synergistically passivate various defects within the 1.83 eV perovskite. The incorporation of T3FpT effectively inhibits non‐radiative recombination and reduces the residual stress within the ...
