Preliminary Study of a Ninj1‐Loaded Bimodal Ultrasound/NIR Fluorescence Targeted Molecular Probe for Diagnosing Early‐Stage Inflammation in Coronary Microvascular Dysfunction

Advanced Healthcare Materials, EarlyView.
Coronary microvascular dysfunction (CMD) targeting remains a challenge for precise diagnosis. This work presents a dual‐modal nanoprobe (T‐IR780‐NBs) that combines ultrasound contrast with near‐infrared fluorescence. This technology utilizes proteomics‐derived antibodies that specifically localize to inflamed and injured cardiac tissue, enabling ...

Colloid‐Mediated Synthesis of Hierarchically Porous Amorphous Catalyst for Durable Industrial‐Scale Water Electrolysis

Advanced Materials, EarlyView.
A colloid‐mediated electroless plating (CMEP) strategy is proposed to fabricate hierarchically porous, amorphous Fe‐doped NiWB electrocatalysts under ambient conditions. The in situ formation of Fe‐W‐O colloidal species guides the formation of robust, porous catalyst layers with excellent mass transfer and durability, sustaining 500 mA cm−2 for 2000 h,

Improvement of Detection Sensitivity of Microbubbles as Sensors to Detect Ambient Pressure

Sensors, 2018
Microbubbles are considered a promising tool for noninvasive estimation of local blood pressure. It is reported that the subharmonic scattering amplitude of microbubbles decreases by 9 to 12 dB when immersed in the media under an ambient pressure ...

Interfacial Behavior of Methane in Methane/p‐Xylene/Water Systems: First Principles Inspected Using Neutron Imaging and Molecular Dynamics Simulations

Advanced Materials Interfaces, EarlyView.
Pressurized gases reduce interfacial tension (IFT) at the gas‐liquid interfaces, their influence on the liquid–liquid interfaces remains unclear. For model compounds methane, water, and p‐xylene, neutron imaging observation of pressurized three‐phase systems is combined with Molecular Dynamics simulations.

Xylem surfactants introduce a new element to the cohesion-tension theory [PDF]

, 2016
Vascular plants transport water under negative pressure without constantly creating gas bubbles that would disable their hydraulic systems. Attempts to replicate this feat in artificial systems almost invariably result in bubble formation, except under ...
