An Introduction to Contrast-Enhanced Ultrasound for Nephrologists [PDF]

Nephron, 2017
Contrast-enhanced ultrasound (CEUS) is an emerging technology with no known nephrotoxicity. CEUS has been utilized in cardiac and abdominal imaging for decades in Asia and Europe and has recently received greater attention in the United States with its approval for characterization of indeterminate liver lesions.

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Contrast Enhanced Ultrasound

Radiologic Clinics of North America
Per dešimtmečius kontrastinis ultragarsinis tyrimas tobulėjo tiek per aplikavimo vietą, tiek per pačias kontrastines medžiagas. Kontrastinis ultragarsinis tyrimas padarė revoliuciją diagnostiniam vaizdų fiksavimui, kur jis konkuruoja su kitais diagnostikos būdais, tokiais kaip magnetinis rezonansas ar kompiuterinė tomografija.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...
