Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Dirac‐Source Linear X‐Ray Detection Diode

Advanced Functional Materials, EarlyView.
Monolayer graphene imparts near linear current‐voltage behavior to a perovskite X‐ray detection diode, contrasting with conventional diode‐like responses. Exploiting graphene's Dirac dispersion and a Schottky‐like back‐to‐back junction, the device achieves six‐orders‐of‐magnitude dark current suppression while retaining linearity over 200 V, enabling ...

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

Metrology for advanced radiotherapy using particle beams with ultra-high dose rates

Physics in Medicine & Biology
Abstract Dosimetry of ultra-high dose rate beams is one of the critical components which is required for safe implementation of FLASH radiotherapy (RT) into clinical practice. In the past years several national and international programmes have emerged with the aim to address some of the needs that are required for translation of this ...
