Waste Adsorbent Valorization of Biopolymer‐Modified Zn–Fe Layered Double Hydroxides for Crystal Violet Removal and Enhanced Nonenzymatic Urea Detection

open access: yesChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This graphical abstract illustrates the synthesis of Zn–Fe LDH composites with biopolymers (chitosan, cellulose, and carrageenan) for the efficient removal of crystal violet dye. The resulting spent adsorbents are subsequently repurposed for electrocatalytic urea detection, demonstrating a sustainable, circular approach to wastewater treatment and ...

Neural Assimilation and Accommodation in Trilinguals: An fMRI Study at 7 T

open access: yesHuman Brain Mapping, Volume 47, Issue 11, 01 August 2026.
Using brain activation and representational similarity analysis at 7 T‐MRI, this study demonstrated that the trilingual brain flexibly modulated neural assimilation and accommodation. While Chinese and English shared highly similar neural representations, Japanese engaged distinct patterns, highlighting script‐driven effects on multilingual neural ...

Utilizing Lighting Design Software for Simulation and Planning of Machine Learning Based Angle-of-Arrival (AOA) Visible Light Positioning (VLP) Systems

open access: yesIEEE Photonics Journal, 2022
We propose to utilize a commercially available DIALux lighting design software for simulation and planning of machine learning (ML) based angle-of-arrival (AOA) visible light positioning (VLP) systems. Here, different ML models, for example, second order linear regression (LR), artificial neural-network (ANN), and convolutional neural-network (CNN) are

Mineralogy, mineral chemistry, and redox equilibria in ten aggregate particles from asteroid Bennu

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1905-1927, August 2026.
Abstract Examination of 10 Bennu aggregate particles has revealed the presence of many phases which taken together can provide constraints on the oxygen fugacity (fO2) of Bennu samples. Phyllosilicates (saponite and serpentine), carbonates, oxides (magnetite, chromite), sulfides (pyrrhotite, pentlandite), phosphate (hydroxyapatite, Na‐Mg‐phosphate ...

Direct Observations of Large‐Scale Wave Structure and Post‐Sunset Rise of the Ionosphere in the Generation of Equatorial Spread F

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large‐scale wave structure (LSWS) and the post‐sunset rise (PSSR) are two key factors in the generation of equatorial spread F (ESF). In this study, we reported continuous and direct observations of LSWS and PSSR and their effects on seeding ESF by Sanya incoherent scatter radar (SYISR) and ionosonde in September–October 2024.

Osteoarthritis: Epidemiology, Diagnosis, and Treatment

open access: yesMedComm, Volume 7, Issue 7, July 2026.
Osteoarthritis (OA) is a multifactorial degenerative joint disease and a leading cause of disability worldwide. This graphical abstract summarizes the epidemiology, diagnostic strategies, and therapeutic approaches of OA. OA development is driven by aging, metabolic dysregulation, and mechanical stress, leading to progressive joint degeneration ...
