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.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Reengineering the Baldree Traffic Simulator for turfgrass wear and traffic research

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Historically, turfgrass researchers utilized the Baldree Traffic Simulator (BTS) to imitate foot traffic for the evaluation of athletic field wear tolerance and performance. Research was conducted to reengineer the BTS “feet” to improve adaptability and compatibility with other aerification units and determine biophysical effects on two native

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Low‐Dose Electron Total Scattering Analysis Resolves Non‐Crystalline Phase Separation in Polymer Semiconductors and Device Multilayers

Small Methods, Volume 10, Issue 11, 8 June 2026.
The performance of polymer blend semiconductors is governed by both the degree of phase separation and crystallization, but these two aspects have remained unresolved. We report methods for mapping amorphous‐amorphous as well as amorphous‐crystalline phase separation in polyfluorene‐based polymer blends using spatially resolved nanobeam electron total ...
