Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

A Single‐Aliquot Strategy for Simultaneous Carbon Isotope Confirmation of 6‐Oxo‐Androstenedione and Testosterone Misuse in Doping Control

open access: yesDrug Testing and Analysis, EarlyView.
This method enables simultaneous carbon isotope confirmation of 6‐oxo‐androstenedione and testosterone markers from a single urine aliquot, using bench‐top extraction, two preparative HPLC steps with intermediate acetylation, and GC/C/IRMS analysis. It was fully validated according to WADA requirements, and real samples demonstrated its fitness for ...

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

open access: yesEcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

A New Attempt On The F5 Criterion [PDF]

open access: yes, 2008
Faugère's criterion used in the F5 algorithm is still not understand and thus there are not many implementations of this algorithm. We state its proof using syzygies to explain the normalization condition of a polynomial.

Integrated Solvent‐Catalyst‐Dopant Strategy via Acidic DES for Synthesizing Lignin‐Derived Carbon Dots With High‐Quantum Yield to Achieve Efficient Photocatalytic Degradation of Tetracycline

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A deep eutectic solvent (ChCl/pTSA) platform enables integrated solvent, catalyst, and dopant functions, producing sulfur‐doped carbon quantum dots with a high sp2‐C content (82.8%) and a quantum yield of 56.9%. When combined with TiO2, the CQDs form TiOC and TiOS interfacial bridges, achieving 97.3% tetracycline photodegradation with excellent ...

Sulfonated‐TiO2 Nanorod–Reinforced PEO Composite Solid Electrolytes for High‐Voltage Solid‐State Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces a high‐performance composite solid electrolyte (CSE) utilizing actively sulfonated TiO2 (STiO2) nanorods within a PEO matrix. The 1D ceramic network chemically promotes LiTFSI dissociation and creates continuous fast‐hopping pathways for Li+ ions, delivering an ionic conductivity of 1.5 × 10−4 S cm−1 at room temperature, an ...

A Robust Densification Strategy Toward Ultrahigh Energy Density in All‐Organic Dielectric Polymer Films

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable densification strategy is proposed by incorporating sucrose into a fluoropolymer matrix to build a robust hydrogen‐bond crosslinking network. The intermolecular interactions effectively facilitate polar phase transformation and reduce free volume fraction.
