Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

High Voltage, EarlyView.
ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.

Image Restoration Algorithm and Propagation Mechanism of Partial Discharge Streamer in Oil–Pressboard Insulation Needle–Plate Electrode

High Voltage, EarlyView.
ABSTRACT Oil–pressboard system is the main insulation form of oil‐immersed transformers, which is prone to partial discharge (PD) and subsequent faults due to contamination or moisture ingress. To investigate the evolutionary characteristics of PD streamers under varying voltages and insulation dimensions, streamer images were captured using a high ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

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

International Journal of Cancer, Volume 159, Issue 4, Page 1005-1016, 15 August 2026.
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 ...

Zinc Oxide Nanoparticles for Food Applications: From Synthesis and Functional Properties to Safety and Sustainability

Food Frontiers, Volume 7, Issue 4, July 2026.
Green and conventional synthesis routes produce ZnO nanoparticles with tunable physicochemical properties for food applications, ZnO‐NPs enhance antimicrobial activity, UV protection, and food preservation through ROS generation and ZN2+ release. However, particle dissolution, migration, cytotoxicity, and environmental concerns highlight the need for ...

Numerical investigation of acoustic cavitation characteristics of a single gas–vapor bubble in soft tissue under dual-frequency ultrasound

Ultrasonics Sonochemistry
The viscoelastic tissue under dual-frequency ultrasound excitation affects the acoustic cavitation of a single gas–vapor bubble. To investigate the effect of the cavitation dynamics, the Gilmore-Akulichev-Zener (GAZ) model is coupled with the Peng ...

A new in silico model to precisely design focused ultrasound brain therapies

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Focused ultrasound (FUS) combined with microbubbles enables transient and noninvasive blood–brain barrier (BBB) opening, facilitating targeted drug delivery. However, accurate treatment planning remains difficult due to inter‐patient anatomical variability and the common assumption in simulations that brain tissues behave like water.
