Polarization‐Reoriented Piezocatalysis Enables Plastic Upcycling with Mechanical Energy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mixed plastic waste remains difficult to upcycle selectively under mild conditions, and piezocatalysis has been constrained by a persistent see‐saw effect: Stronger piezoelectric polarization tends to divert charge carriers away from the very active sites that drive catalysis. Sha et al.

Acoustic cavitation mechanism: A nonlinear model

Ultrasonics Sonochemistry, 2012
During acoustic cavitation process, bubbles appear when acoustic pressure reaches a threshold value in the liquid. The ultrasonic field is then submitted to the action of the bubbles. In this paper we develop a model to analyze the cavitation phenomenon in one-dimensional standing waves, based on the nonlinear code SNOW-BL.

“Effects of High‐Intensity Ultrasound on the Structural, Technofunctional, and Allergenic Properties of Groundnut (Arachis hypogaea L.) Protein Isolates: A Review”

Food Chemistry International, EarlyView.
ABSTRACT The growing global demand for sustainable, nutritionally balanced protein sources has intensified interest in plant‐derived proteins, particularly those derived from oilseeds such as groundnut (Arachis hypogaea L.). However, although groundnut protein isolates (GPIs) have high nutritional quality, they exhibit limitations in technofunctional ...

Acoustic cavitation and sonochemistry [PDF]

, 2012
Sonochemistry is the use of cavitation for achieving a chemical conversion. When microbubbles are driven in the nonlinear regime, localized extreme temperatures (up to 10000 K) and pressures (up to 1000 bar) can be reached upon collapse, the surrounding liquid remaining ambient,thus giving origin to intriguing phenomena, such as light emission ...
