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.

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

A DNP‐Supported Solid‐State NMR Approach to Study Nucleic Acids In Situ Reveals Berberine‐Stabilized Hoogsteen Structures in Mitochondria

open access: yesAngewandte Chemie, EarlyView.
Mitochondria are vital for energy production and rely on intricate nucleic acid structures to regulate gene expression. Using DNP‐ssNMR (dynamic nuclear polarization solid‐state NMR), we observed G‐quadruplex formation in intact mitochondria treated with berberine.

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.

New data on the mammalian fauna from the late middle Eocene (MP 15–16) of Mazaterón (Soria, Spain): The youngest presence of the genus Prodissopsalis (Hyaenodonta, Hyaenodontidae) in Europe

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The Hyaenodonta were the most diverse carnivorous mammals in the European Eocene and were classically divided into three subfamilies: Sinopaninae, Arfianinae, and Proviverrinae, with this latter being the most successful of the three, as it exhibited a much larger geographic and temporal range.

Highly Stable Sn─Pb Perovskite Solar Cells Enabled by Phenol‐Functionalized Hole Transporting Material

open access: yesAngewandte Chemie, EarlyView.
Stability is the key challenge for Sn─Pb perovskites. This work tackles the critical stability issue by introducing phenol hydroxylation in the hole transporting material (HTM). The phenol group enhances oxidation resistance and regulates crystallization kinetics, while fluorine improves energy alignment.
