Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light

Angewandte Chemie, EarlyView.
Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning

Hybrid Heterostructures of Nanostructured Si Membrane and MoS2 for Self‐Powered Photodetectors

Advanced Electronic Materials, EarlyView.
A scalable MoS2/Si nanomesh vertical heterostructure is developed for self‐powered photodetection. The nanostructured junction enhances conductivity, expands the active heterointerface, and enables a transition from photovoltaic to avalanche‐assisted operation, delivering markedly improved photoresponse over planar counterparts.

Light‐Induced Dispersion of Pd Single Atoms Provides Steady‐State‐Stabilized Activity for Photocatalytic H2 Generation

Angewandte Chemie, EarlyView.
High photon flux causes (re)distionpersion of atomic Pd species on TiO2 in photocatalytic experiments, whereas Pt SAs undergo continuous agglormation. This allows light‐driven stabilization of active Pd centers for sustained H2 evolution. ABSTRACT In recent years, the use of single atoms (SAs) has become increasingly significant in photocatalysis ...

Degradation Mechanisms of Rutile‐Type TiO2 Photoanodes during Photoelectrochemical Water Splitting

Advanced Energy Materials, EarlyView.
Combining operando dissolution measurements with microscopy and spectroscopy characterizations, we reveal different degradation mechanisms of rutile‐type TiO2 photoanodes during photoelectrochemical water splitting. In acidic electrolytes, degradation is inhibited once TiO2 reaches saturation.

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Long term spectral irradiance measurements of a 1000-watt xenon arc lamp [PDF]

Spectral irradiance measurements over the range of 200 to 1060 nm were made on a 1000-watt xenon arc lamp over a period of 1500 hours. Four sets of measurements were made after periods of 70, 525, 1000, and 1500 hours of operation.

Selective Electrolysis of Water Under Artificial Seawater Conditions Using Transition Metal Borate Anodes

Advanced Energy Materials, EarlyView.
The borate‐based cobalt‐iron catalyst promotes selective oxidation of water rather than chlorine evolution reaction during electrolysis of seawater. When integrated into a zero‐gap electrolyzer prototype, this catalyst supports robust splitting of artificial seawater into oxygen and hydrogen on an extended timescale.

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

Advanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...
