Published on 2025-10-20 by Yuna Hachikubo, Hiryu Hayashi, Mano Ando, Mayu Morita, Misaki Oshima, Abdul Manaf Hashim, Nurul Hanis Azhan, Takayuki Ota, Satoshi Takei @MDPI
Abstract: Traditional lithography processes use resist materials that require organic solvents during the development step but also often contain components derived from PFASs (per- and polyfluoroalkyl substances), raising concerns about environmental pollution and sustainability. PFASs are difficult to degrade, and their long-term effects on ecosystems and human health are the subject of international concern, making the development of alternative technologies an urgent priority. Lithography is a fundame[...]
Our summary: This study presents a water-developable positive photoresist made from plant-derived sugar chains. It offers superior resolution and sensitivity while eliminating the need for PFAS and organic solvents. The findings suggest a sustainable alternative for photolithography processes in various applications.

Modeling and Optimization of Argon-Activated Electrohydraulic Plasma Discharge Process for p-Nitrophenol Remediation
Published on 2025-10-19 by Anilkumar Krosuri, Yunfei Zhou, Muhammad Aamir Bashir, Robinson Junior Ndeddy Aka, Sarah Wu @MDPI
Abstract: This study presents a statistical modelling and optimization of an argon-activated electrohydraulic plasma discharge (EHPD) process for the degradation and mineralization of p-nitrophenol (p-NP) in water. The EHPD reactor design incorporated dual dielectric plates to initiate plasma discharge through a central orifice. A fractional factorial design (FFD) was first employed to screen four operating variables, including argon flow rate, pH, applied power, and persulfate dosage, on the p-NP degrada[...]
Our summary: This study optimizes an argon-activated electrohydraulic plasma discharge process for p-nitrophenol degradation. Key factors influencing degradation efficiency were identified and optimized using statistical methods. The optimized process achieved high degradation efficiency and energy efficiency, demonstrating its potential for sustainable water treatment.

Wettability Alteration in Reservoir Rocks for Enhanced Oil Recovery and Field Application
Published on 2025-10-16 by Ruiyang Liu, Huabin Li, Zhe Li, Xudong Yu, Lide He, Xutong Guo, Feng Zhao, Huaqiang Shi, Wenzhao Sun @MDPI
Abstract: The peripheral reservoirs of the Daqing Oilfield exhibit low permeability and partial heterogeneity, resulting in a rapid injection pressure increase, limited sweep efficiency, and significant residual oil retention. To enhance recovery, this study synthesized a fluorocarbon siloxane (FHB) via free radical addition for rock surface wettability modification. At a concentration of 0.1 wt%, FHB increased water and oil contact angles to 136° and 117°, respectively, at 60 &[...]
Our summary: This study presents a method for enhancing oil recovery by modifying rock wettability using fluorocarbon siloxane (FHB). FHB increased contact angles and reduced interfacial tension, improving fluid transport and mobilizing residual oil. A field trial demonstrated a significant increase in oil output, validating the approach in real reservoir conditions.

Insights from a Roadside Rain Garden
Published on 2025-10-16 by Hadeer Saleh, Dibyendu Sarkar, Zhiming Zhang, Michel Boufadel, Rupali Datta @MDPI
Abstract: Urban stormwater runoff is increasingly recognized as a critical but underexplored pathway for per- and polyfluoroalkyl substances (PFAS) to enter aquatic environments. This work investigated the occurrence and behavior of 40 PFAS compounds in stormwater runoff entering a roadside rain garden in Secaucus, New Jersey, during six storm events between August 2023 and July 2024. Total PFAS concentrations (Σ40 PFAS) ranged from 1437 to 1615 ng/L, with perfluorobutane sulfonate (PFBS, 23[...]
Our summary: This study examines PFAS compounds in stormwater runoff entering a roadside rain garden. Total PFAS concentrations were consistently high, with specific compounds dominating. The rain garden showed limited effectiveness in reducing PFAS levels, indicating a need for improved urban water management strategies.

Abstract: In this study, to address the problems of fading and cracking of ancient architectural paintings caused by environmental aging, a weather-resistant nano-coating material was prepared using self-made nano-zinc oxide as the UV agent and water-based fluorocarbon coating as the binder. Taking slides and painted wooden boards as the coating objects, respectively, the transparency, ultraviolet absorption capacity, and weather resistance of the coating were detected by ultraviolet-visible spectrophotom[...]
Our summary: This study developed a weather-resistant nano-coating using nano-zinc oxide and water-based fluorocarbon. The coating demonstrated high transparency and effective protection against UV damage and cracking. It has been successfully applied to protect ancient painted cultural relics in specific museums.

Patent published on the 2025-08-28 in WO under Ref WO2025179186 by MACHACEK MARK THOMAS [US] (Galvan Anthony [us], Henderson Katie [us], Machacek Mark [us])
Abstract: PFAS (Per- and polyfluoroalkyl substances) contained in water are remediated by a process in which colloidal as aphrons (CGAs) are generated under shear and with surfactants, either added to the liquid or inherent in the PFAS. Preferably a pump is used to generate the CGAs, to move CGAs and liquid through the system, and to induce gas or air into the pump. The resulting foam that rises to the surface is comprised of various small bubbles, producing a very large surface area effective in attracti[...]
Our summary: This method generates colloidal gas aphrons (CGAs) to remove per- and polyfluoroalkyl substances (PFAS) from water.
