Comparison of Extremely Low Frequency Electromagnetic Waves in Different Parts of Residential Houses in Yazd City [PDF]

Journal of Environmental Health and Sustainable Development
Introduction: Extremely low frequency (ELF) waves are less than 300 Hz. Electrical devices with city electricity are one of the most important sources of generating ELF waves.

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

N‐Doped Carbon Encapsulated FeV2S4/Fe Nanorods as Fast‐Charging Anodes for All‐Climate Sodium‐Ion Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The well‐chosen N‐doped carbon encapsulated FeV2S4/Fe nanorods as new anode materials exhibit remarkable all‐climate fast‐charging sodium storage properties. Various in‐situ/ex‐situ experimental characterizations and DFT calculations confirm the high electronic conductivity, fast Na+ diffusion and complex conversion‐based reaction mechanism.

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the

Directed Hole Localization Stabilizing Interfacial Sulfur Species to Boost α‐C–H Activation for Selective Biomass Photo‐oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Efficient α‐C–H bond activation and directional conversion for selective biomass photo‐oxidation are achieved by integrating polarization and interface engineering strategies in P‐doped ZnIn2S4 polar photocatalysts, which leverage hole localization and stable interfacial sulfur species, endowing bio‐based HMF at 94.4% conversion with 94.5% selectivity ...

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.
