Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

Advanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Unusual Temperature‐Enhanced Bulk Photovoltaic Effect Beyond the Centrosymmetric Phase in CuCrP2S6 van der Waals Crystals

Advanced Functional Materials, EarlyView.
Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...

The sulphur and chlorine contents of grass and maize silage

Acta Agriculturae Slovenica, 2001
In seven defined samples of grass and in six samples of maize silage the contents of sulphur and chlorine were determined by two analytical procedures: both elements with X-ray fluorescence spectrometry (XRF), sulphur separately with inductively coupled ...

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

Advanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a
