Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

Advanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...

Excited State Modulation in Carbene‐Metal‐Amides to Design Fast and Bright Blue Delayed Fluorescence

Advanced Functional Materials, EarlyView.
Gold‐centered carbene‐metal amide (CMA) materials with carbonyl‐group substitution on the amide donor ligand. Molecular design ensures that the charge transfer (CT) state is lower in energy than the locally excited (3LE) states. The energy difference between CT and LE states controls the rate of the delayed fluorescence.

Importance of boundary effects in diffusion of hydrocarbon molecules in a one-dimensional zeolite channel

, 2010
Single-file diffusion of propane and toluene molecules inside a narrow, effectively one-dimensional zeolite pore was experimentally studied by Czaplewski {\sl et al.} Using a stochastic lattice gas approach, we obtain an analytical description of this ...
