θ‐Metallacarboranes as Sustainable Photoredox Oxidation Catalysts of Unsaturated Fatty Acids From Oil and Pork Lard

The sustainable management and valorization of unsaturated fatty acid‐rich lipid streams is a key challenge within circular economy strategies. Herein, we present a proof of concept for the photoredox oxidation of unsaturated fatty acids using θ‐metallacarborane complexes Na[Co(1...

Unexpected 4 × 4 Charge Density Wave in 1 H -NbTe2 Monolayer

Abstract Transition metal ditellurides exhibit structural and electronic properties distinct from their selenide and sulfide counterparts, including the stabilization of multiple charge density wave (CDW) phases. Within the niobium compound family, notable differences in structur...

Introducing 2-Thioxocoumarins as a New Class of Photosensitizers for Antimicrobial Photodynamic Therapy

Abstract Antimicrobial photodynamic therapy (aPDT) has gained increasing attention as an alternative approach to combat bacterial resistance, although the development of efficient visible-light photosensitizers (PSs) remains a major challenge. Despite the extensive investigation...

Orientation-Dependent Domain Structure and Buffer Layer Functionality of Epitaxial Bixbyite Sc2O3 Thin Films

Abstract We report the epitaxial growth of high-quality bixbyite-structured Sc2O3 thin films on differently oriented Yttria-stabilized Zirconia (YSZ) substrates by radio-frequency magnetron sputtering. Films grown along the ⟨111⟩ orientation exhibit atomically flat surfaces, full...

Surface Termination Unlocks Photocatalytic Potential: Reshaping Structure and Electronics in Ultrathin MoS 2 /TiO 2 Heterojunctions

Anatase TiO 2 stands out for its exceptional chemical stability, nontoxicity, and robust photocatalytic capabilities; however, its intrinsically wide bandgap severely restricts its activity to the ultraviolet spectrum, limiting practical efficiency under solar illumination. To ci...

Laser‐Induced Local De‐Doping in Organic Semiconductors

ABSTRACT This study explores control of the doping level in organic semiconductor films using scanning continuous wave laser radiation. The feasibility of this one‐step non‐contact post‐deposition approach is explored for a benchmark material system comprising the high‐mobility p...

Measuring masses of transiting Earth-like planets: first insights from the PLATO RV Data Challenge

Abstract The PLATO Stellar Variability Mitigation Working Group designed a radial-velocity (RV) data challenge to assess the precision and accuracy achievable on RV semi-amplitudes in the context of the future PLATO follow-up. Using Sun-as-a-star observations obtained with HARPS-...

Acox2 deficiency induces cardiac dysfunction via cross-organ metabolic reprogramming in mice

Abstract Background Secondary cardiomyopathies are a major cause of heart failure (HF) with diverse etiologies and high mortality rates. For example, over 50% of patients with end-stage liver disease develop cardiac dysfunction, clinically termed cirrhotic cardiomyopathy (CCM). W...
