Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Characterization of a Modified Clinical Linear Accelerator for Ultra-High Dose Rate Beam Delivery

Applied Sciences
Irradiations at Ultra-High Dose Rate (UHDR) regimes, exceeding 40 Gy/s in single fractions lasting less than 200 ms, have shown an equivalent antitumor effect compared to conventional radiotherapy with reduced harm to normal tissues.

Glucose Deprivation‐Driven Concurrent Induction of Apoptosis/Disulfidptosis/Ferroptosis by Tumor Targeting Nanoassemblies in Triple‐Negative Breast Cancer Therapy

Advanced Functional Materials, EarlyView.
Innovative hybrid nanoassemblies installed with ferrocene, D‐α‐tocopherol succinate, and phloretin exploit the metabolic vulnerability of triple‐negative breast cancer under glucose starvation. By blocking glucose uptake, this single nanoplatform simultaneously orchestrates apoptosis, disulfidptosis, and ferroptosis to achieve synergistic and ...

Preclinical Ultra-High Dose Rate (FLASH) Proton Radiation Therapy System for Small Animal Studies

Advances in Radiation Oncology
Purpose: Animal studies with ultrahigh dose-rate radiation therapy (FLASH, >40 Gy/s) preferentially spare normal tissues without sacrificing antitumor efficacy compared with conventional dose-rate radiation therapy (CONV). At the University of Washington,

Radiation safety of ultra‐high dose rate electron accelerators for FLASH radiotherapy

Medical Physics
AbstractBackgroundAn ultra‐high dose rate (UHDR) electron accelerator for FLASH radiotherapy (RT) produces very intense bremsstrahlung by the interaction of the electron beam with objects both inside and outside of the accelerator. The bremsstrahlung dose per pulse is typically 1–2 orders of magnitude larger than that of conventional RT x‐ray treatment

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

IN VITRO FLASH EFFECT AS A FUNCTION OF ULTRA-HIGH DOSE RATES WITH PROTON BEAM

International Journal of Particle Therapy
Radiotherapy at ultra-high dose rates (UHDR, >50 Gy/s) is rapidly gaining attention thanks to its sparing of healthy tissues and unaltered tumor control (FLASH effect). However, the mechanisms of FLASH remain unclear. In particular, little data is available at even higher dose rates and thus its potential therapeutic benefits remain unknown. In this
