Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Research on the interpretation method of channel waves for various abnormal bodies in geologically transparent working faces

Meitan kexue jishu, 2023
The transparency of mine geology is a new requirement for safe and efficient mining of coal mines. For working faces with complex geological conditions, channel wave detection technology is one of the commonly used geophysical prospecting methods.

Enhancing the CPT correlation with the small strain shear stiffness of sands

Ain Shams Engineering Journal, 2017
The cone penetration test (CPT) is a valuable geotechnical insitu test. Yet, the CPT correlations with the small strain shear modulus and seismic shear wave velocity still need more research to enhance their accuracy.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

Advanced Materials, EarlyView.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

The application of seismic surveys to the evaluation of shallow coal deposits [PDF]

, 1986
The viability of using surface seismic techniques in the exploration of shallow coal deposits in the UK is investigated. The geological factors that affect the economic viability of a prospective site are the overburden ratio and the presence of faulting,
