Nonthermal Food Processing Technologies: A Comprehensive Review

Future Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Origin of broadband acoustic emission from a dancing cavitation bubble

Applied Physics Express
Acoustic cavitation generates bubbles exhibiting violent expansion and contraction under intense ultrasound in liquids. The acoustic emissions (AE) spectrum from cavitation bubbles contains harmonics, subharmonics, ultraharmonics, and broadband noise ...

Focused Ultrasound‐Induced Mechanical Ablation Affects the Carbohydrate Metabolism of Residual/Peri‐Focally Localized Glioblastoma Cells

International Journal of Cancer, EarlyView.
Glioblastoma (GBM) is highly aggressive and therapy‐resistant, warranting exploration of novel treatment strategies, among them mechanical high‐intensity focused ultrasound (mFUS), which holds significant promise for tumor ablation. The present study examined mFUS‐induced changes specifically in carbohydrate metabolism, which affects vulnerability to ...

Acoustic cavitation, bubble dynamics and sonoluminescence

Ultrasonics Sonochemistry, 2007
Basic facts on the dynamics of bubbles in water are presented. Measurements on the free and forced radial oscillations of single spherical bubbles and their acoustic (shock waves) and optic (luminescence) emissions are given in photographic series and diagrams.

Histological characterization of HIFU lesions

International Journal of Hyperthermia
Background: High intensity focused ultrasound (HIFU) can destroy tissue by thermal ablation which may be accompanied by acoustic cavitation and/or tissue water boiling, but the biological and histological effects of these treatments have not been fully ...

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 ...

Comparison of the SMI Technique and CEUS for the Assessment of Microvasculature in Leiomyosarcoma and Its Clinical Value for Application

Journal of Clinical Ultrasound, EarlyView.
SMI and CEUS can clearly reflect the microvascular situation in fibroids and effectively guide the clinical treatment of patients with uterine fibroids, but the effect of SMI is better than that of CEUS in guiding the treatment of patients, which can provide a reference for the selection of clinical treatment programs.
