Enhanced Photocatalytic Antibiotic Micropollutants Removal Resulting From a Synergism Between Cu Single Atoms and Carbon Vacancies on Graphitic Carbon Nitride

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Scheme of the synergistic degradation for antibiotic micropollutants in the Cu/ag‐C3N4 system. Photocatalytic processes driven by visible‐light irradiation offer a sustainable means of micropollutants removal from aquatic environments without the addition of reagents.

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

Derivation of the Relativistic Doppler Effect from the

open access: yes, 2008
This paper demonstrates that calculation and interpretation of the relativistic Doppler effect is possible using only the Lorentz force and relativity theory. This method eliminates the need for the Lorentz transformation and time dilation.

Phase Engineering Enabled Excellent Power Factor and Reduced Thermal Conductivity in ZrCoSb‐Based Half‐Heusler Compounds

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In situ precipitation of Zr6Co16Si7 in ZrCoSb‐based half‐Heusler enables Fermi level optimization and enhanced phonon scattering. Electrical conductivity is significantly improved while the power factor continuously increases, reaching ~3.36 mW m−1 K−2.

Cation Distribution in Li2CaSiO4:Gd, Pr, Na Uncovered Through Anomalous Diffraction

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Li2CaSiO4 co‐doped with Gd3+ and Pr3+ shows strong blue‐to‐UV‐B up‐conversion. Herein, we explore the doping element distribution in order to discern the reason for the strongly supportive co‐doping effect using high‐resolution Rietveld refinement and multiple‐edge anomalous dispersion measurements.

Dilithium Enediamide Derived From a 1,4‐Diaza‐1,3‐diene: Reactivity of a Strongly N‐Basic, Highly C‐Nucleophilic Compound Toward C–H Acids

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The lithium enediamide complex 2 with intrinsically inverted C–N bond polarity combines strong basicity with unusual reactivity: deprotonation of malonates enables C–C bond formation without electron transfer. Depending on malonate substitution, electrophilic substitution or addition occurs at the enediamide CC bond.

Electroweak Interaction Model with an Undegenerate Double Symmetry

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
The initial P-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.

Characterisations of Lorentz transformations

open access: yes, 1985
A.D. Alexandrov in 1953, and E.C. Zeeman in 1964 independently published papers proving that the assumption of linearity is unnecessary for characterising Lorentz Transformations.

Dilithium Enediamide Derived From 1,4‐Diaza‐1,3‐Diene: An Electron Reservoir Enabling Variable Reactivity Toward Carbonyl Compounds

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Upon reduction of 1,4‐diaza‐1,3‐diene 1 to the dilithium enediamide 2, the polarity of the C = N bonds is reversed ‐ a classic case of umpolung. This behavior is particularly evident in reactions of the dianion 2 with carbonyl compounds and also explains why 1,4‐diaza‐1,3‐diene ligands do not always act merely as spectator ligands. 1,4‐Diaza‐1,3‐dienes

Magneto‐Electrochemical Effect on La‐Doped GaFeO3 as a Supercapacitor Electrode for Energy Storage

open access: yesElectron, EarlyView.
The electrochemical performance of La‐doped Gallium Ferrite (La‐doped GaFeO3 ${\text{GaFeO}}_{3}$) synthesizes via a conventional solid‐state reaction method; this has been studied by the application of an external magnetic fields. ABSTRACT The electrochemical performance of La‐doped GaFeO3 ${\text{GaFeO}}_{3}$ synthesizes via a conventional solid ...
