3+ mon, 1+ week ago  (171+ words) This schematic illustrates how in situ electrochemical surface-enhanced Raman spectroscopy (EC-SERS) provides fingerprint vibrational information that bridges catalyst design, theoretical simulations, interfacial intermediate identification, and reaction-mechanism elucidation. By correlating surface states, solvent interactions, and structure'performance relationships, EC-SERS enables a closed-loop…...

1+ hour, 45+ min ago  (1316+ words) APS staff members Suresh Narayanan, Dana Capatina and Matt Spilker monitor live data from the XPCS beamline. ALCF's Polaris supercomputer is closely integrated with the APS, enabling near real-time data analysis during live experiments. Using the XPCS beamline and rapid…...

2+ hour, 20+ min ago  (528+ words) To charge and discharge batteries, electrodes accept and release electrons. Because techniques that scientists can use to study these surfaces require conditions that don't reflect real-world environments, scientists developed a method called modulation-excitation X-ray spectroscopy (ME-XAS). DOE SCIENCE NEWS SOURCE…...

1+ week, 9+ hour ago  (1168+ words) Beyond visible machinery risks, small leaks and poor waste habits often go unnoticed, leading to major regulatory and contamination issues. Workplace safety programs often focus on visible risks such as machinery, fall hazards and chemical handling. While these areas matter,…...

1+ mon, 3+ week ago  (461+ words) For centuries, it was believed that the production of oxygen relied on one component: photosynthesis (the conversion of light energy into chemical energy). Plants and algae use sunlight to convert carbon dioxide into oxygen, providing the foundation of life on…...

3+ week, 5+ day ago  (834+ words) In a recent opinion article, marine scientists and electrochemists listed a number of reasons why it's unlikely that metallic nodules on the deep seafloor could produce oxygen in total darkness. A 2024 study that claimed to have discovered an entirely new…...

15+ hour ago  (721+ words) HONG KONG, April 13, 2026 /PRNewswire/ -- Lingnan University today, 13 April, hosted its University Assembly with guest of honour Prof Arieh Warshel, Nobel Laureate in Chemistry in 2013 and widely recognised as one of the founding figures of computational chemistry. In his lecture Electrostatic…...

4+ hour, 10+ min ago  (207+ words) Kinetic evaluation demonstrated that hydrophobic tuning could enhance enzymatic turnover rates significantly, sometimes by factors exceeding twofold, while in other instances, it served to selectively slow reactions, thereby improving substrate specificity. This dual capability showcases the potential for tailored catalytic…...
