Article Abstract

We investigate the scaling form of appropriate timescales extracted from time-dependent correlation functions in rotating turbulent flows. In particular, we obtain precise estimates of the dynamic exponents z_{p}, associated with the timescales, and their relation with the more commonly measured equal-time exponents ζ_{p}. These theoretical predictions, obtained by using the multifractal formalism, are validated through extensive numerical simulations of a shell model for such rotating flows.

Lignin-intercalated WS with synergistic adsorption for efficiency lead removal.

Bioresour Technol

Tungsten disulfide (WS), a two-dimensional adsorbent material, has garnered great attention in removing lead ions (Pb) from water due to their extensive exposed adsorption sites. However, WS nanosheets inevitably agglomerated and stacked during the preparation and adsorption process, leading to reduced adsorption efficiency. Current method of enhancing WS dispersion is mainly blending with synthetic polymers, but these synthetic polymers themselves do not possess adsorption properties, resulting adsorption effect enhancement poorly.

Dual-functional hydrochar via hydrothermal carbonization for norfloxacin removal: Fractal adsorption kinetics and mechanism elucidation.

Sci Total Environ

September 2025

Laboratoire Physico-Chimie des Matériaux, Substances Naturelles et Environnement, Faculty of Sciences and Techniques, Abdelmalek Essaâdi University, Tangier, Morocco.

Escalating concentrations of norfloxacin (NFX) in surface and wastewaters demand sustainable remediation strategies. In this study, dual-functional hydrochars were synthesized from argan nut shells (ArNS) via hydrothermal carbonization (HTC), with process conditions optimized by varying temperature (150-200 °C) and residence time (2-6 h). Among the materials, H1:5@150-4-prepared at 150 °C for 4 h with a biomass-to-water ratio of 1:5-exhibited the best performance, achieving a monolayer NFX adsorption capacity of 27.

Solvation Structure of Np in a Noncomplexing Environment.

Inorg Chem

September 2025

Pacific Northwest National Laboratory, Richland, Washington 99352, United States.

The solvation structure of an Np ion in an aqueous, noncomplexing and nonoxidizing environment of trifluoromethanesulfonic (triflic) acid was investigated with X-ray absorption spectroscopy (XAS) combined with ab initio molecular dynamics (AIMD) and time-dependent density functional theory (TDDFT) calculations. Np L-edge X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) data were collected for Np in 1, 3, and 7 M triflic acid using a laboratory-scale spectrometer and separately at a synchrotron facility, producing data sets in excellent agreement. TDDFT calculations revealed a weak pre-edge feature not previously reported for Np L-edge XANES.

Wrist biomechanics remain incompletely understood due to the complexity of experimental measurements in this multi-bone joint system. Finite element analysis provides a powerful alternative for investigating internal variables such as carpal kinematics and displacement patterns. This technical brief compares two bone representation approaches, all-cortical versus cortical-trabecular, using two distinct finite element models developed from the same wrist CT dataset.

We model Auger spectra using second-order Møller-Plesset perturbation (MP2) theory combined with complex-scaled basis functions. For this purpose, we decompose the complex MP2 energy of the core-hole state into contributions from specific decay channels and propose a corresponding equation-of-motion (EOM) method for computing the doubly ionized final states of Auger decay. These methods lead to significant savings in computational cost compared to our recently developed approaches based on coupled-cluster theory [F.
