Iron‐modified natural sand as a heterogeneous Fenton catalyst for methylene blue and textile wastewater treatment

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The continuous discharge of organic dyes into freshwater poses long‐term environmental risks. Heterogeneous Fenton‐like processes using iron (Fe)‐modified silica (SiO2) supports are promising for dye removal; however, catalysts derived from natural sand and operating under near‐neutral conditions remain relatively underexplored ...

Contrasts or Carryover? Demands–Capabilities Fit and Task‐Level Intrinsic Motivation Across the Workday

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT In the course of a workday, employees attend to various tasks whose challenge might be equal to, higher than, or lower than employees' present level of capabilities. Moreover, employees encounter these tasks sequentially throughout the day with different levels of prior motivation. Investigating carryover effects in motivation from one task to

Assessment of Human Thermal Stress Dynamics and Regional Drivers Across the Arabian Peninsula During 1990–2022 From Observations

open access: yesInternational Journal of Climatology, EarlyView.
The results reveal that thermal stress varies substantially across the four AP regions, with winter cold stress in Region I, year‐round heat stress in Region II, pronounced summer heat stress in Region III, and persistent strong to very strong heat stress from late spring to early autumn in Region IV.

Settlement preferences and population dynamics in early farming societies of Central Europe (5400−4950 BCE)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The expansion of the Linearbandkeramik (LBK; ca. 5400–4950 BCE) represents one of the most significant episodes of prehistoric population movement during the Neolithisation of Europe. Although migration is widely accepted as the principal mechanism of this expansion, the roles of ecological adaptation, population pressure and environmental ...

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

open access: yesJournal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.
