This article presents a method for preparing stable and reproducible fatty acid (FA) stock solutions, which are essential for studying lipid signaling, metabolism, and lipid droplets (LDs). The authors developed a technique using ultrasonication and ethanol to create FA micelles, which can be used in both in vivo and in vitro studies. The method eliminates the need for albumin, avoids FA degradation, and allows for precise control over FA concentrations. The authors also compare their method with existing techniques and demonstrate its effectiveness in various biological studies, including the investigation of LD dynamics and lipid metabolism.

A recent review provides a detailed comparison of gypsum and silica scaling in membrane desalination, shedding light on their unique formation mechanisms and behaviors. The research identifies the challenges each scaling type poses to desalination efficiency and highlights critical differences in how they interact with organic foulants. By understanding these distinct behaviors, the study offers valuable insights that can inform targeted strategies for improving desalination processes and their sustainability.

"AI Finally Cracks Human-Level Spatial Reasoning: New Model Beats GPS at Understanding 'Behind the Starbucks, Near the Broken Sign'"

A groundbreaking study led by Dr. Feng Wang reveals why current AI fails to grasp real-world spatial language—and unveils the DPEC model that closes the gap.

The core of this article is to explore the mechanism by which the ruthenium (Ru) integration effect influences ruthenium-cobalt (RuCo) bimetallic nanoparticles in enhancing water-splitting properties. The research team synthesized RuCo bimetallic nanoparticles (RuCo@NC) with atomically dispersed Ru on nitrogen-doped carbon. They found that atomically dispersed Ru not only serves as the primary active site for the hydrogen evolution reaction (HER) but also promotes the oxidation of the Co surface to CoOOH*, thereby becoming a highly active site for the oxygen evolution reaction (OER). The optimized catalyst, RuCo@NC-1, exhibited outstanding performance. In alkaline conditions, it required only 217 and 96 mV of overpotential to reach a current density of 10 mA‧cm⁻² for OER and HER, respectively. This study offers valuable insights into the design of Ru-based electrocatalysts for water splitting.

In this study, the controllable synthesis of highly stable Ag₅₆ clusters was achieved using 4-vinylbenzoic acid (abbreviated as p-VBA) and tert-butyl mercaptan as ligands by precisely regulating reaction parameters such as temperature and solvent. Furthermore, the intermediates Ag₂₀, Ag₃₁, Ag₃₂ and the dimers of the intermediate Ag₃₁/Ag₃₂, Ag₃₀-bpbenz (bpbenz, 1,4-di(4-pyridyl)benzene) and Ag₃₁-bpe (bpe, 1,2-bis(4-pyridyl)) were successfully captured. This series of nanoclusters exhibited a unique fluorescence aggregation-induced redshift phenomenon as the π–π interaction of the ligand. In addition, the Ag₅₆ nanocluster can be used as near infrared fluorescence sensors for Br⁻/I⁻ and their detection limits were as low as 85 and 105 nM, respectively. The results of this study provide new ideas and methods for the synthesis of metal clusters and their applications in the field of ion sensing.
