Thermal driven water desalination system using forward osmosis
Patent published on the 2025-03-06 in WO under Ref WO2025049562 by CANTRELL BOB I [US] (Cantrell Bob [us])
Abstract: A system and method for water desalination using forward osmosis to address problems associated with scarcity of freshwater around the world. The system uses ammonium bicarbonate as the draw solution to draw out freshwater through a forward osmosis (FO) membrane from an amount of saltwater or other contaminated water initially directed through one side of the FO membrane. The ammonium bicarbonate draws the desalinated water through the membrane of the FO membrane. Brine or other solutes are dire[...]
Our summary: System using forward osmosis and ammonium bicarbonate to desalinate water efficiently and cost-effectively. Ammonium bicarbonate draws out freshwater through a forward osmosis membrane, while brine is directed away. Recycled for multiple batches of desalination.

Optimal Placement of Leakage Sensors in Urban Gas Networks Based on an Ant Colony Algorithm and System Clustering
Published on 2025-02-28 by Zhewen Sui, Xiaobing Yuan, Baoping Cai, Fangqi Ye, Qingqing Duan, Zhiqiang Zhao, Xiaoyan Shao, Xin Zhou, Zhiming Hu @MDPI
Abstract: In urban gas network leakage monitoring, the optimized placement of sensors plays a pivotal role in ensuring public safety and minimizing system maintenance costs. This study introduces an innovative approach that integrates hierarchical clustering with ant colony optimization (ACO) to optimize sensor layouts in urban gas networks. The hierarchical clustering technique is first employed to evaluate the strategic importance of each monitoring node, which subsequently influences the pheromone impo[...]

Performance and Mechanism of UV/H2O2 Oxidation of Aminotris(Methylphosphonic Acid) Antiscalant of the Reverse Osmosis Concentrate
Published on 2025-02-27 by Wenfang Liu, Feng Qian, Yaru Lei, Yihai Chen, Yonghui Song @MDPI
Abstract: In wastewater treatment, reverse osmosis (RO) technology is gaining significance. However, antiscalants in RO systems harm the environment by hindering hardness removal and causing phosphorus pollution in receiving waters. This research employed the UV/H2O2 process to degrade a typical phosphoric-based antiscalant, aminotris(methylphosphonic acid) (ATMP). Compared to using UV light or H2O2 alone, the UV/ H2O2 technique significantly enhanced the degradation and conversion of ATMP. With UV irradi[...]
Our summary: Performance of UV/H2O2 oxidation of ATMP antiscalant in RO concentrate. UV/H2O2 process significantly enhances degradation and conversion of ATMP. Optimal H2O2 dosage is 4 mM for efficient conversion to orthophosphate.

Rotenone Induces Parkinsonism with Constipation Symptoms in Mice by Disrupting the Gut Microecosystem, Inhibiting the PI3K-AKT Signaling Pathway and Gastrointestinal Motility
Published on 2025-02-27 by Li Liu, Yan Zhao, Weixing Yang, Yuqin Fan, Lixiang Han, Jun Sheng, Yang Tian, Xiaoyu Gao @MDPI
Abstract: Parkinson’s disease (PD) is one of the most common neurodegenerative diseases. Constipation is a prodromal symptom of PD. It is important to investigate the pathogenesis of constipation symptoms in PD. Rotenone has been successfully used to establish PD animal models. However, the specific mechanism of rotenone-induced constipation symptoms is not well understood. In this work, we found that constipation symptoms appeared earlier than motor impairment in mice gavaged with a low dos[...]
Our summary: Rotenone induces Parkinsonism with constipation symptoms in mice by disrupting the gut microecosystem, inhibiting the PI3K-AKT signaling pathway, and gastrointestinal motility. Low-dose rotenone causes parkinsonism with constipation symptoms in mice by disrupting the intestinal microecosystem and inhibiting the PI3K-AKT pathway and gastrointestinal motility. Specific gut microbiota taxa are associated with motor and constipation symptoms, inflammation, and gut and brain barrier status in PD mice.

Transient Gel Diffusiophoresis of a Spherical Colloidal Particle
Published on 2025-02-26 by Hiroyuki Ohshima @MDPI
Abstract: A general theory is presented to analyze the time-dependent, transient diffusiophoresis of a charged spherical colloidal particle in an uncharged gel medium containing a symmetrical electrolyte when an electrolyte concentration gradient is suddenly applied. We derive the inverse Laplace transform of an approximate expression for the relaxation function R(t), which describes the time-course of the ratio of the diffusiophoretic mobility of a weakly charged spherical colloidal particle, possessing [...]
