Amphiphilic Motif Triggers Microheterogeneity in Low‐Melting Mixtures

Microheterogeneity in low‐melting mixtures of ethylene glycol and chemically modified choline derivatives synthesized on purpose is here proposed. Novel cholinium ions with one or two N ‐butyl substituents or an N ‐hydroxybutyl chain are synthesized for the first time. Synthesis...

Strontium isotopic signatures and source apportionment in urban soils of Salgótarján: unraveling the impact of industrial emissions

Abstract Urban soil contamination is primarily associated with human activities, especially industrial by-products, which have introduced high concentrations of heavy metal(loid)s from diverse sources over centuries of city development. This study investigated the distribution of...

Ultrastrong Au–Te bonding drives disorder in monolayer ZrTe5 on gold

Abstract Monolayer ZrTe $$_5$$ is predicted to host a large-gap quantum spin Hall phase, motivating efforts to isolate single layers of the material. Gold-assisted exfoliation produces clean monolayers of many chalcogen-terminated van der Waals crystals, but the strong Te–Au bond...

Glass Surfaces Rendered Hydrophobic by Silylation and Sol–Gel Coatings: Optical, Wetting, and Chemical Stability

Abstract This study presents a comparative evaluation of three strategies for hydrophobizing glass surfaces: direct surface silanization with dimethyldichlorosilane (DMDClSi), the application of a hybrid silica coating (H-SiO2), and the use of a hexamethyldisilazane (HMDS)-modifi...

Fluctuation–dissipation of the Kuramoto model on fruit-fly connectomes

We investigate the distance from equilibrium using the Kuramoto model via the degree of fluctuation–dissipation violation as the consequence of different levels of edge weight anisotropies. This is achieved by solving the synchronization equations on the raw, homeostatic weighted...

Epitaxial MgSnN 2 on 4H‐SiC (0001): An Earth‐Abundant Nitride for Green Optoelectronics and Photovoltaics

ABSTRACT Group II–IV‐Nitrides has emerged as a novel class of Earth‐abundant semiconductors. Owing to their tunable bandgaps these materials are attractive candidates for replacing expensive Ga‐based alloys in photovoltaics and green‐gap optoelectronics. In this work, epitaxial g...

Influence of soil physicochemical properties on the distribution and variability of 137Cs activity concentrations in urban soils of Ózd, Hungary

Abstract Urban soils exhibit substantial heterogeneity in their physicochemical properties influencing the sequestration of 137 Cs. This study investigates the distribution of 137 Cs in urban soils from Ózd, Hungary, and its relationship with soil properties using multivariate st...

Development and Application of Computational Chemistry Methods

Computational chemistry has become an essential bridge between microscopic theory and measurable chemical behaviour [...]

Heterogeneity in trustworthiness reshapes the spatial evolution of trust

Trust is fundamental to cooperation in social and economic interactions, yet its emergence is difficult to explain when individuals occupy asymmetric roles and differ in trustworthiness. How heterogeneous trustee behaviours interact with their spatial organisation to shape popula...

Electrical Properties and Interfacial Strain in Thermally Oxidized 4H‐SiC MOS Structures Under Different Post‐Oxidation Annealing

ABSTRACT The electrical behavior of SiO 2 /4H‐SiC interfaces is a central challenge for the development of high‐efficiency MOSFETs, where trap states and interfacial structural distortions can affect carrier mobility and device reliability. In this work, we investigate thermally...

Machine learning enhanced prediction of optical properties via reverse Monte Carlo method

We present a machine learning (ML) approach for the accelerated extraction of optical properties from the experimental reflection electron energy loss spectroscopy (REELS) spectra by the reverse Monte Carlo (RMC) method. Taking platinum (Pt) as an example, experimental REELS spec...

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

ABSTRACT Narrow‐bandgap perovskite solar cells (PSCs) are promising absorbers for tandem photovoltaics; however, their performance remains limited by interfacial recombination and instability, particularly Sn 2+ oxidation and halide‐related degradation. Although fullerene derivat...

Fusion at scale: Critical enablers in global energy transitions

Fusion is a promising sustainable energy source that can potentially contribute to achieving the most ambitious climate goals with firm carbon-free baseload electricity. Due to recent advancements, fusion is transitioning from a purely research stage to a pre-commercialisation ph...
