GENERAL LORENTZ TRANSFORMATIONS AND APPLICATIONS

, 2014
In this paper, we solve a formidable nonlinear problem presented by a veteran Physicist C.B.van Wyk in his paper on General Lorentz Transformations and applications [1].We arrived at the solution by first examining the problem in a non-invariant manner ...

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

ENERGY &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

Superluminal quantum reference frames

New Journal of Physics
Particles cannot travel faster than the speed of light, nor can information. Nonetheless, this assumption has been frequently questioned over the years.

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

European 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.

Lorentz transformations and reflection operators in Minkowsky space-time

, 1990
A geometric approach to the study of pure Lorentz transformations is presented, through a systematic use of suitable reflection operators in space-time.

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

European 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.

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

European 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

The spin-statistics connection: Some pedagogical remarks in response to Neuenschwander's question

Electronic Journal of Differential Equations, 2000
Q: Is there a simple proof of the Spin-Statistics Theorem? A: Not if all that is assumed is invariance under the Euclidean Group. When this hypothesis is supplemented by invariance under restricted Lorentz transformations, the key move is to disregard ...

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

Electron, 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 ...
