Lithium-ion batteries are widely used in portable devices and electric vehicles, and their production grows continuously. Aging is the main reason for battery retirement, which causes substantial waste production and can potentially result in water or soil pollution. Capacity recovery of aged cells could become a great alternative to their recycling. In this work, we found that electrolyte refilling restores the capacity of Li-ion pouch cells due to a decrease in internal impedance. The capacity increment depends on the battery State-of-Health (SoH) prior to refilling (20–100%) and is insignificantly affected by the electrolyte extraction method employed (supercritical and normal-pressure electrolyte extraction). The electrolyte extraction does not influence either composition or electrochemical characteristics of the active materials. The obtained results pave the way for enhanced second life applications of lithium-ion batteries.

Abstract
Safety-aligned language models often encode that a request is harmful yet still comply with it. We turn this gap between internal recognition and observable behavior into an inference-time defense. The proposed activation-steering method uses a multiplicative operator that amplifies the residual-stream component along a harm-recognition direction. Intervention strength scales with the model’s own assessment of ...

Camera traps are a key tool for non-invasive wildlife monitoring, yet models trained on existing benchmarks often generalize poorly to new regions due to domain shift, class imbalance, and natural variability in illumination, season, and background. We introduce PACTraD, a benchmark of 116,973 annotated camera trap images collected in a protected area of the Baikal ...

We study the density-matrix kinetics of a charged test particle in two types of Coulomb environment. For a prescribed Gaussian potential, averaging the random-unitary dynamics leads to a Born–Novikov memory equation; Novikov’s identity is exact, but its closure requires a second-order approximation. An equilibrium quantum bath instead yields a Born–Redfield equation with ordered correlators and ...

In this paper, we study a new class of wave solutions to the SU(2) Yang-Mills equations in the
region outside field sources. They represent a significant addition to the wave solutions obtained
in our previous publications describing non-Abelian transverse progressive waves propagating
in the direction of the Cartesian z-axis. In the new paper, wave solutions to the considered
system ...

We addressed the task of chemical characterization of the aerosol emitted by heated tobacco products (HTPs) and of the smoke emitted by conventional/commercial cigarettes, usually adopted as a reference. Emphasis was placed on quantifying constituents for enabling the identification of novel compounds through targeted and untargeted analyses, and the evaluation of reductions in toxicant exposure under ...

We study coherent electric manipulation of magnetic field induced localized states at a double kink of a helical edge in a HgTe/CdHgTe quantum well. An in-plane magnetic field opens a gap in the one-dimensional (1D) edge spectrum, while changes in the edge orientation generate localized in-gap states at the kinks. We show that, for suitable ...

New dichloro-chlorobismuthate supramolecular hybrid, (Me3NH)2{[BiCl5](Cl2)}, has been prepared and characterized by X-ray diffractometry as well as Raman spectroscopy. The self-assembly of 2D dihalogen-halometalate architecture succeeds via Cl⋯Cl halogen bonds (3.066 and 3.543 Å). These features were assessed with DFT calculations and Interaction region indicator analysis. ...

We derive the local pressure tensor generated by the original Rosenfeld fundamental measure theory (FMT) for hard-sphere fluids from an arbitrary infinitesimal deformation. The variation of a finite-distance FMT kernel is written via the line integrals of the local deformation gradient along the straight segment connecting its end points. The resulting symmetric pressure tensor consists ...

Maintaining plant health is crucial for crop quality, food security, and agricultural productivity. Although deep learning methods have shown strong potential for species, disease, and severity classification, most existing approaches tackle these tasks separately, failing to exploit shared representations and interdependencies among them. Furthermore, the variability of disease symptoms, such as subtle differences in size, ...

A series of new coumarin-azine fluorophores based on 1,2,4-triazinyl and pyridinyl substituted derivatives of 7-aminocoumarin was synthesized via a nucleophilic substitution of hydrogen (SNH) reaction followed by an inverse electron-demand Diels–Alder transformation. The primary photophysical properties of 3-triazinyl coumarins and their pyridine analogs was investigated in toluene and acetonitrile solutions. Thus, the emission of the fluorophores in ...
