Polyoxometalate as Hydrogen–Electron Hub in Metal–Organic Complex for Electrocatalytic Nitrate Reduction to Ammonia

open access: yesAdvanced Science, EarlyView.
To tackle low electrocatalytic nitrate reduction to ammonia efficiency in neutral media, this work designs chain‐like dinuclear/trinuclear polyoxometalate‐based metal‐organic complexes. Metal clusters provide nitrate adsorption/activation sites, while polyoxometalates (POMs) drive water dissociation to generate active hydrogen (*H) that migrates to ...

Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

open access: yesCivil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.
Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized

Reduced auger recombination in mid-infrared semiconductor lasers [PDF]

open access: yes, 2011
A quantum-design approach to reduce the Auger losses in two micron InGaSb type-I quantum well edge-emitting lasers is reported. Experimentally realized structures show a 3X reduction in the threshold, which results in 4.6 lower Auger current loss at room

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

open access: yesChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.
