Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Compatible metasurface for ultra-wideband radar and switchable infrared stealth

Optics Express
In response to the rapid advancements in radar detection technology and the widespread deployment of infrared sensors, single-function stealth materials are increasingly challenged to meet the sophisticated demands of concealment within complex electromagnetic environments. As a result, there is a pressing need for research into metamaterial structures

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

Small Structures, EarlyView.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...

Citizen science project on urban canids provides different results from camera traps but generates interest and revenue

Wildlife Biology, EarlyView.
As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...

Imposed expiratory resistance, dynamic hyperinflation and locomotor power and fatigue

Experimental Physiology, EarlyView.
Abstract Expiratory flow limitation results in dynamic hyperinflation, dyspnoea and premature exercise intolerance. We aimed to measure whether expiratory resistance reduces locomotor power via limiting maximal voluntary motor activity, exacerbating muscle fatigue, or both.
