The effect of square corners on the ignition of solids [PDF]

open access: yes, 1993
the influence of square corners on the ignition of a solid exposed to a step in surface temperature is analyzed by means of large activation energy asymptotics. This study begins by considering the case of a semi-infinite square corner, applicable to the

Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Tramadol is frequently co‐prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid‐sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of the multicenter IGNITE ADOPT‐PGx pragmatic trial of patients undergoing ...

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...
