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.

Сyclocondensation of phenyl, ortho-bromophenyl, para-phenylphenyl, para-methoxycarbonylphenyl, para-tolyl and para-methoxyphenyl boronic acid with curcumin in the presence of K3PO4 upon refluxing in 1,4-dioxane for 24 h leads to the formation of curcumin-based 2,2-diaryl-1,3,2-dioxaborines in good yields. The absorption-emission spectra of the synthesized fluorescent conjugates and 1,3,2-dioxaborine with para-biphenyl boronic substituent demonstrated the highest quantum yield. Among the compounds studied, conjugate curcumin with para-methoxycarbonylphenyl boronic substituent ...

Text-to-image models use user-generated prompts to produce images. Such text-to-image models as DALL-E 2, Imagen, Stable Diffusion, and Midjourney can generate photorealistic or similar to human-drawn images. Apart from imitating human art, large text-to-image models have learned to produce combinations of pixels reminiscent of captions in natural languages. For example, a generated image might contain ...

Benzenoid hydrocarbons are structurally regular aromatic compounds, which makes them well suited for quantitative structure–property relationship (QSPR) studies. This study presents a QSPR analysis of nineteen benzenoid hydrocarbon species using degree-based topological co-indices. We developed a Python program to compute eleven degree-based topological co-indices from molecular graphs and evaluated their ability to explain variations in ...

In this work, we combine experimental characterization and molecular dynamics (MD) simulations to elucidate the molecular mechanisms governing the impregnation of mefenamic acid (MFA) into nanocrystalline cellulose (NCC) aerogels. NCC aerogels were impregnated with MFA in scCO2, and low-temperature nitrogen adsorption revealed a concentration-dependent decrease in surface area, pore volume, and pore size, with an ...

condensate. Specifically, at half-filling, the local pair potential is significantly enhanced
by up to 77.8% at edge centers and up to 148.9% at corners, subsequently boosting their
local critical temperatures by up to 13.5% and ...

We investigate the effect of weak interband impurity scattering on the intertype (IT) domain between type-I and type-II superconductivity in diffusive two-band superconductors. Our results show that the significant broadening of the IT domain with increasing band diffusivity ratio, previously established in the absence of interband scattering, persists under weak interband scattering. However, depending on ...
