Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

open access: yesAdvanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Investigation into moisture desorption in concrete constructions

open access: yesEngineering Structures and Technologies, 2011
The article investigates the moisture desorption of concrete constructions. Three concrete mixtures with different V/C ratio were tested. In one of the mixtures, a plasticizer was used. The test revealed changes in bulk humidity and weight.

Enhanced Tantalum Superconducting Resonator Performance via All‐Surface Organic Monolayer Passivation

open access: yesAdvanced Functional Materials, EarlyView.
The internal quality factor of tantalum superconducting resonators is significantly increased by ∼140% in the low photon regime by passivating their surfaces with a high‐quality alkene self‐assembled monolayer. Our methodology promises to enhance the performance of superconducting quantum circuits.

Extraordinary n‐type Tellurium‐Free Thermoelectric Performance of Y‐Doped BiSe via Synergistic Effect of Vacancies and Band Engineering

open access: yesAdvanced Functional Materials, EarlyView.
Yttrium doping in Sb‐alloyed BiSe synergistically induces Bi vacancies and flattens conduction bands, simultaneously slashing lattice thermal conductivity by 50% and boosting the power factor. The optimized n‐type Bi0.64Sb0.3Y0.06Se delivers a peak zT of 0.91 at 393 K (average zT 0.76, 300–523 K) and an 8‐pair module with 4.6% conversion efficiency ...

Desorption Behaviors and Adsorption Behaviors after Desorption of Trivalent Metal Ions Adsorbed on Chelating Resin: Comparison between Scandium(III) and Other Metal Ions

open access: yesJournal of MMIJ
Scandium (Sc) generally lacks independent deposits and is mainly recovered as a by-product of the smelting of other ores. Scandium is present in laterite ores in concentrations ranging from tens to hundreds of ppm.

Heat-Integrated Liquid–Desorption Exchanger (HILDE) for CO2 Desorption

open access: yesEnergy Procedia, 2016
AbstractA novel type of separating heat exchanger, called a heat-integrated liquid−desorption exchanger (HILDE), applied to a typical CO2 desorption process, has been investigated both numerically and experimentally. Process simulations, hydrodynamic and mass transfer experiments, and a preliminary cost evaluation have been used to compare HILDE to the

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

open access: yesAdvanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...
