Purpose: Proton FLASH has been investigated using cyclotron and synchrocyclotron beamlines but not synchrotron beamlines. We evaluated the impact of dose rate (ultra-high [UHDR] vs. conventional [CONV]) and beam configuration (shoot-through [ST] vs.

The oceanic dissolved organic matter (DOM) reservoir is one of Earth's largest carbon pools, yet the factors contributing to its recalcitrance and persistence remain poorly understood. Here, we employed ultra-high resolution mass spectrometry (UHRMS) to examine the molecular dynamics of DOM from terrestrial, marine and mixed sources during bio-incubation over weekly, monthly, and one year time spans. Using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), we classified DOM into three distinct categories (Consumed, Resistant and Product) based on their presence or absence at the start and end of the incubation.

In radio frequency identification (RFID), differences in spectrum policies and tag misreading in different countries are the two main issues that limit its application. To solve these problems, this article proposes a composite right/left-handed transmission line (CRLH-TL)-based reconfigurable antenna for ultra-high frequency near-field and far-field RFID reader applications. The CRLH-TL is achieved using a periodically capacitive gap-loaded parallel plate line.

Vanadium-based materials exhibit a high theoretical capacity and diverse valence states, rendering them promising candidate anodes for lithium-ion batteries (LIBs). However, the cycling and rate performance are limited by their weak structural stability and electrical conductivity. Herein, a rational amorphization strategy has been developed to construct dual-anion vanadium oxysulfide nanoflowers (VSO NFs) with partial amorphous components and abundant oxygen vacancies as anode material for LIBs.

Fracture toughness is a critical indicator for the application of NiTi alloys in medical fields. We propose to enhance the fracture toughness of NiTi alloys by controlling the spatial grain size (GS) gradient. Utilizing rolling processes and heat treatment technology, three categories of NiTi alloys with distinct spatial GS distributions were fabricated and subsequently examined through multi-field synchronous fracture tests.
