Energized dispersive guided extraction (EDGE): a promising tool for analytical chemistry applications.
Anal Methods

Analytical chemistry demands precise sample preparation methods to ensure accurate qualitative and quantitative determinations, especially those capable of clean-up and preconcentration of target analytes. Extraction plays a crucial role in enhancing the selectivity and sensitivity of analytical procedures. Thus, Energized Dispersive Guided Extraction (EDGE) has emerged as an innovative alternative to traditional methods, such as Soxhlet, maceration, and percolation, as well as modern techniques like Accelerated Solvent Extraction (ASE), Supercritical Fluid Extraction (SFE), and Microwave or Ultrasound Assisted Extraction (MAE and UAE).

Objective: This study aims to investigate the monthly variation patterns of bioelectrical impedance (BEI) along 24 meridian pathways in healthy individuals.
Methods: A cohort of 684 healthy middle-aged participants from North China was enrolled between July 1, 2017, and September 5, 2020. BEI measurements were consistently recorded along the 24 meridian pathways over the study period.
Polariton lattices as binarized neuromorphic networks.

Spin-Optics laboratory, St. Petersburg State University, St. Petersburg, 198504, Russia.
We introduce a novel neuromorphic network architecture based on a lattice of exciton-polariton condensates, intricately interconnected and energized through nonresonant optical pumping. The network employs a binary framework, where each neuron, facilitated by the spatial coherence of pairwise coupled condensates, performs binary operations. This coherence, emerging from the ballistic propagation of polaritons, ensures efficient, network-wide communication.

Electromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth's magnetosphere through the wave-particle interaction. Traditionally understood as a diffusive process, these interactions account for long-term electron flux variations (> several minutes). However, theories suggest that chorus waves can also cause rapid (< 1 s) electron acceleration and significant flux variations within less than a second through a nonlinear wave-particle interaction.

Based on the bidirectional electromigration (BIEM) technique, a corrosion inhibitor solution was prepared by mixing 1 mol/L triethylene tetramine with deionized water. The effects of current density, charging time, and corrosion inhibitor on critical current density and hydrogen content of rebar were investigated. Subsequently, the hydrogen embrittlement risk of rebar was further characterized by mechanical property tests.
