Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Determination of explosion limits - criterion for ignition under non-atmospheric conditions

, 2014
Many industrial processes are run at non-atmospheric conditions (elevated temperatures and pressures, other oxidizers than air). To judge whether and if yes to what extent explosive gas(vapour)/air mixtures will occur or may be generated during ...

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

Advanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Evaluating Ammonia's Flammability and Explosion Hazards in Air and Oxygen at Elevated Conditions: Data Generation and Review According to the New European Standard

Chemical Engineering Transactions
Many industrial processes operate under non-atmospheric conditions, involving high pressure and temperature in a variety of oxidising media. It is therefore essential to assess the potential for explosive atmospheres of (vapour)/oxidising gases under ...

Numerical simulation of hydrogen leakage diffusion in a small underground garage with different parking space modes

Emergency Management Science and Technology
In recent years, hydrogen energy has been widely applied in various industries, but it may also bring a series of safety concerns. Especially in confined spaces like underground garages, where high-pressure hydrogen leaks can potentially cause combustion

Nocturnal Intraocular Pressure Monitoring With a Soft Contact Lens Sensor for Glaucoma Management

Advanced Materials, EarlyView.
A soft contact lens sensor enables continuous, noninvasive monitoring of nocturnal intraocular pressure (IOP) under closed‐eye sleep conditions. By integrating a highly compliant inductive–capacitive circuit onto a commercial lens, the device achieves record sensitivity and stable performance.

Nonlocal Metaspire: A Scalable Elastic Material Platform With Decoupled Mechanical Modes

Advanced Materials, EarlyView.
Nonlocal Metaspire introduces sequential rotation to realize wider scalability in implementing complex nonlocal couplings in elastic metamaterials while suppressing unintended mode coupling. Numerical results clarify the underlying wave motions, demonstrate mode‐decoupled roton and maxon formation, and support a straightforward extension to higher ...
