Commissioning of a precision preclinical 200 kV x‐ray irradiator based on modular adaptations

Medical Physics, EarlyView.
Abstract Background Preclinical research in radiation oncology encompasses a range of methodologies, including in vitro cell studies and in vivo small animal experiments, as well as in silico studies to evaluate radiation‐induced side effects and tumor responses.

Optical surface information‐based respiratory phase‐sorting and motion‐incorporated reconstruction for SPECT imaging

Medical Physics, EarlyView.
Abstract Background Respiratory motion during the single photon emission computed tomography (SPECT) acquisition can cause blurring artifacts in the reconstructed images, leading to inaccurate estimates for activity and absorbed doses. Purpose To address the impact of respiratory motion, we utilized a new optical surface imaging (OSI) system to extract

Verification of dose and dose rate for quality assurance of spread‐out‐Bragg‐peak proton FLASH radiotherapy using machine log files

Medical Physics, EarlyView.
Abstract Background Ultra‐high dose rate radiotherapy elicits a biological effect (FLASH), which has been shown to reduce toxicity while maintaining tumor control in preclinical radiobiology experiments. FLASH depends on the dose rate, with evidence that higher dose rates drive increased normal tissue sparing.

Aqueous and Non‐Aqueous Synthesis of 2‐(Dimethylamino)ethyl Methacrylate (Co)Polymers by Solution Radical Polymerization: Modeling and Experimental Study

Macromolecular Reaction Engineering, EarlyView.
The radical polymerization kinetics of DMAEMA is studied in both aqueous and nonaqueous solution. Solvolysis of the nonionized monomer occurs in aqueous and aqueous‐alcohol systems, leading to the formation of copolymer or terpolymer; this complexity does not arise when DMAEMA is in its ionized form.

Heat Sterilizable Coatings Based on Nafion and Graphene Quantum Dots With Advanced Antibacterial Performance

Nano Select, EarlyView.
Electrostatically assembled layer‐by‐layer waterborne nanocoatings comprising negatively charged Nafion and positively charged imidazole modified‐graphene quantum dots can inhibit the growth of bacteria and can withstand dry heat sterilization without any decline in their activity.
