Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Purification of Li2CO3 Obtained through Pyrometallurgical Treatment of NMC Black Mass from Electric Vehicle Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

Thermal Conduction in Laser‐Driven Tin Plasmas and the Sensitivity of Plasma Properties to the Flux Limiter

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We study the role of thermal conduction in laser‐produced tin plasma sources of extreme ultraviolet (EUV) light using radiation‐hydrodynamic simulations. Adopting the flux‐limited Spitzer–Härm approach, we investigate the sensitivity of the electron temperature, electron density, net in‐band emissivity, and conversion efficiency to the choice ...

Beyond BMI: Unsupervised Machine Learning Clustering of Bioelectrical Impedance Phenotypes Is Associated With Weight‐Recovery Trajectories in Anorexia Nervosa

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective To identify data‐driven body composition phenotypes in patients with moderate‐to‐extreme anorexia nervosa (AN) using machine learning (ML) clustering of bioelectrical impedance analysis (BIA) parameters, and to test whether these phenotypes have specific psychopathological and childhood trauma profiles while correlating with early ...

Constructed Red Phosphorus/BiVO4 S‐Scheme Heterojunction for Efficient Photocatalytic Overall Water Splitting

open access: yesEcoEnergy, EarlyView.
An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.

Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

open access: yesEcography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Climatic thresholds and temporal decoupling drive reproductive phenology in Neotropical cloud forests: a 36‐year analysis

open access: yesEcography, EarlyView.
Reproductive phenology influences ecosystem functioning and climate sensitivity in tropical montane cloud forests, but phase‑specific climatic thresholds and the temporal coupling between flowering and fruiting remain poorly quantified over decadal scales. We analyzed a 36‑year monthly record (1983–2018) from a Venezuelan cloud forest (15 focal species)

Global patterns of treeline predictability and the gap between the forest and the treeline

open access: yesEcography, EarlyView.
The alpine treeline is the highest elevation at which trees can grow, which is assumed to be controlled by temperature and globally predictable. However, many upper forest limits (UFLs) do not reach this elevation, due natural factors and human disturbance.
