Experimental and Theoretical Investigations on Magneto‐Electrochemical Oxygen Evolution Reaction of CoFeP Nanorods

open access: yesAdvanced Materials Interfaces, EarlyView.
CoFeP exhibits an overpotential of 335 mV at 50 mA cm−2 and a Tafel slope of 116 mV dec−1 without a magnetic field, whereas under the magnetic field of 2000 G, these values lowered to 235 mV and 93 mV dec−1, respectively. The enhancement is attributed to magnetic‐field‐induced spin polarization, surface reconstruction, and increased ECSA from 70 to 110

Calculation of the same Lorentz factor using the opposite approach

open access: yesAIP Advances
This article extends the law of electromagnetic oscillation to form a theoretical system of spatial particles. According to this theory, the speed of light is variable and motion is absolute.

Nitrogen‐Doped Amorphous Carbon Film for Enhanced Cu2+ Electrochemical Sensing in Marine Environments

open access: yesAdvanced Materials Interfaces, EarlyView.
Large‐area N‐doped amorphous carbon films are synthesized at room temperature via hybrid linear ion source technique. Nitrogen doping promotes the formation of sp2−C and C‐N bonds, thus enhancing the electrode's sensitivity. These electrodes achieve ultra‐low Cu2+ detection (8 × 10−3 mM) in 3.5 wt% NaCl and exhibit excellent stability/repeatability for

Raman Marker Bands for In Situ Quality Control During Synthesis of 2D Conjugated Metal–Organic Frameworks

open access: yesAdvanced Materials Interfaces, EarlyView.
The properties of 2D conjugated metal–organic frameworks (2D c‐MOFs) are related to their structure and are influenced by the synthesis conditions. Here, in situ, Raman and transmission electron microscopy (TEM) are used to determine Raman marker bands that characterise the reaction progress and yield of phthalocyanine‐based 2D Cu2[ZnPc‐O8] MOFs. Thus,

Unified evolution of electromagnetic sources in homogeneous fields

open access: yesPhysical Review Research
In this work, we study the behavior of elementary electromagnetic sources, i.e., pointlike electric charges and intrinsic magnetic dipoles, in the presence of homogeneous electromagnetic fields in a classical and covariant setting.

Dual Resonant Plasmonic Infrared Pixels for Selective Optical Encoding

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents dual‐resonant plasmonic nanostructures for advanced optical encoding in the mid‐infrared. By optimizing plasmonic resonances in nano‐antennas within ring cavities, selective and simultaneous tunability in both the MWIR and LWIR regions is achieved.

Functional Forms for Lorentz Invariant Velocities

open access: yesMathematics
Lorentz invariance lies at the very heart of Einstein’s special relativity, and both the energy formula and the relative velocity formula are well-known to be invariant under a Lorentz transformation.
