Water Droplet Hammer: Piezoelectric Sensing of Ultrafast Mechanical Transients During Droplet Impact

Small, EarlyView.
Droplet impact on solid surfaces produces an ultrafast substrate‐coupled mechanical response that is resolved by PVDF piezoelectric sensing. An initial impulsive strain pulse is followed by interfacial oscillations before rebound. Weber‐number and timescale analyses reveal how droplet inertia, surface wettability, impact regime, and liquid viscosity ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Concurrent Validity of the Modified Oral Status Survey Tool

Gerodontology, EarlyView.
ABSTRACT Background The Modified Oral Status Survey Tool (MOSST) is a novel instrument designed to assess oral health and function in older adults for whom traditional dental indices are unsuitable. Originally developed for older adults with intellectual disabilities (ID), its reliability and content validity are established, but its concurrent ...
