Selective Electrolysis of Water Under Artificial Seawater Conditions Using Transition Metal Borate Anodes

Advanced Energy Materials, EarlyView.
The borate‐based cobalt‐iron catalyst promotes selective oxidation of water rather than chlorine evolution reaction during electrolysis of seawater. When integrated into a zero‐gap electrolyzer prototype, this catalyst supports robust splitting of artificial seawater into oxygen and hydrogen on an extended timescale.

Serum PFAS in Aircraft Rescue and Firefighting (ARFF) Firefighters From Six U.S. Airport Fire Departments

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Use of aqueous film‐forming foam (AFFF) is a source of exposure to per‐ and polyfluoroalkyl substances (PFAS) for firefighters working in aircraft rescue and firefighting (ARFF) settings. However, data characterizing the association between serum PFAS concentrations and exposure risk factors for ARFF firefighters are limited ...

“It's Not Deterministic and It Will Never Be Deterministic”: A Qualitative Study on Stakeholder Perspectives of Polygenic Risk Score Testing for Post‐Traumatic Stress Disorder

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Post‐traumatic stress disorder (PTSD) causes significant mental and physical distress, yet only a small subset of individuals exposed to trauma develop the disorder. Scientists and clinicians are still unable to predict who will get the disorder or how it will manifest.

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Close Fire Support: Sexton Self-Propelled Guns of the 23rd Field Regiment, 1942–1945 [PDF]

, 2012
On the battlefields of the First World War, initially successful attacks all too often ended in failure because artillery weapons could not be moved up quickly enough to support assault infantry at the sharp end of the fight.
