Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.

Analyzing individual rent price ratios in eastern German agricultural land markets: A GAMLSS approach

open access: yesAgribusiness, EarlyView.
Abstract This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results.

Nature of Anti‐Dissipative High‐Energy Excited States in Quaterpyridine‐Bridged Ruthenium Complexes

open access: yesAngewandte Chemie, EarlyView.
Upon photoexcitation, meta‐connected quaterpyridine‐bridged Ru complexes undergo fast inter‐ligand electron transfer like typical chromophores, but unusually slow intra‐ligand electron transfer within bridge‐centered MLCT states. The energy saved was exploited for photoreductions and photooxidations with model electron donors and acceptors ...

Adapting Image‐Based Models for 1D Data via Spider Plot Transformation and Transfer Learning

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel method enables the use of pretrained image‐based neural networks for complex 1D data, including Raman and mid‐infrared spectra, electrocardiograms, and mass spectrometry. 2D spider plots with false‐color fill enable transfer lerning, therefore enhancing data augmentation and model explainability across diverse spectral and time series datasets.

Light‐Driven Ratchet Mechanism Accelerates Regioselective Metal‐Cation Exchange in a Heterobimetallic Helicate

open access: yesAngewandte Chemie, EarlyView.
Photoswitchable homo‐ and heterobimetallic helicates form with high diastereo‐ and regioselectivity via single‐step self‐assembly or self‐sorting. White‐light exposure autonomously operates one helicate as a molecular ratchet, promoting the selective formation of an out‐of‐equilibrium structure.
