High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

Advanced Science, EarlyView.
An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Flame Suppression in Lithium‐Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility–Flammability Relationship

Advanced Science, EarlyView.
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...

Accuracy of a Priority Medical Dispatch System in Dispatching Cardiac Emergencies in a Suburban Community

Prehospital and Disaster Medicine, 2006
AbstractIntroduction:Over-triage of patients by emergency medical services (EMS) dispatch is thought to be an acceptable alternative to under-triage, which may delay how quickly life-saving care reaches a patient. Previous studies have looked at advanced life support (ALS) misutilization in urban- and county-based EMS systems and have attempted to ...

When time counts: Emergency medical dispatch. Exploring, understanding and addressing issues that impact upon timely and adequate allocation of prehospital medical assistance and resources to cardiac arrest patients

, 2018
When an out-of-hospital cardiac arrest (OHCA) occurs, patient outcome can be influenced by bystanders ability to start cardiopulmonary resuscitation (CPR) before ambulance arrival.
