Preparation of Zwitterionic Silica‐Based Sorbents for Simultaneous Extraction of Acidic and Basic Pharmaceuticals From Water Samples

Journal of Separation Science, Volume 48, Issue 9, September 2025.
ABSTRACT The sol‐gel approach was applied to develop three homemade silica sorbents. These sorbents where functionalized with mixed‐mode zwitterionic exchange groups using only one additive to introduce at once the strong cation‐ (sulfonic groups) and strong anion‐exchange (quaternary amines) moieties. The developed materials were applied for the solid‐

"Weakly" Elliptic Gorenstein Singularities of Surfaces

, 1998
The main message of the paper is that for Gorenstein singularities, whose (real) link is rational homology sphere, the Artin--Laufer program can be continued. Here we give the complete answer in the case of elliptic singularities.

Update on Opium Alkaloids in Food: Exploring Their Occurrence, Effect of Culinary Processing and Advances in Analytical Methodologies

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Following the implementation of the new European legislation on opium alkaloids (OAs) in food in 2023, scientific research has focused on developing analytical methodologies to determine the presence of these compounds in different foods. However, health authorities continue to suggest further studies to evaluate the occurrence of main OAs and

Reinforcement learning–based task allocation and path‐finding in multi‐robot systems under environment uncertainty

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 22, Page 3408-3429, 9 September 2025.
Abstract Autonomous robots have the potential to significantly improve the operational efficiency of multi‐robot systems (MRSs) under environment uncertainties. Achieving robust performance in these settings requires effective task allocation and adaptive path‐finding.

Fish Acellular Dermal Matrix Promotes Repair of Full‐Thickness Skin Defects in Mice and Bama Pigs

Wound Repair and Regeneration, Volume 33, Issue 5, September/October 2025.
ABSTRACT This study aimed to develop an acellular dermal matrix derived from tilapia skin and evaluate its potential as a bioscaffold for skin wound repair. Structural and compositional changes before and after decellularisation were assessed through histological staining, electron microscopy and immunological analysis.

Spline‐Based Framework for Microscopic Contact Zone Modeling in Lubricated Orthogonal Cutting

International Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.
ABSTRACT Accurately predicting the coefficient of friction between tool, chip, and workpiece during machining is essential for a reliable and cost‐effective process. In this context, current numerical methods are often based on homogenized approaches with friction models that use constant friction coefficients; thus, failing to capture local effects ...
