Maneuvering Charge Transport via Insulating Polymer Interface for Steering Photoredox Catalysis

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
Non‐conjugated insulating polymer functions as an electron‐capturing mediator to boost interfacial charge transfer and separation, contributing to considerably enhanced photocatalytic selective organic transformation and solar CO2 conversion under visible light irradiation. Abstract Maneuvering precise and tunable charge transportation has remained the

Hard Machining of Inconel 690 Using Minimum Quantity Nanoparticle‐Enriched Vegetable Oils: A Sustainable Approach

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
This study explores alumina and silica nanoparticle‐enriched soybean oil for sustainable machining of Inconel 690. Alumina‐based nanofluid reduced surface roughness, force, temperature, and tool wear significantly. RSM‐GA optimization validated with 3.04% error highlights its eco‐efficiency, tool life enhancement, and potential for greener ...

Spectroscopy of $z=0$ Lifshitz Black Hole

open access: yes, 2018
We studied the thermodynamics and spectroscopy of a $4$-dimensional, $z=0$ Lifshitz black hole ($Z0$LBH). Using the Wald's entropy formula and the Hawking temperature, we derived the quasilocal mass of the $Z0$LBH. Based on the exact solution to the near-

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

open access: yesJournal 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‐

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

open access: yesComprehensive 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
