Abstract Exploring solid propellants for electric thrusters can simplify the propellant storage and supply units in propulsion systems. In this study, polytetrafluoroethylene (PTFE), commonly used as a pulsed plasma thrusters, was embedded discharge chamber of radio frequency ion thruster (RIT-4) to investigate performance an ablation-type RIT. Experimental results indicate that PTFE decompose ionize stably under ablation within chamber, producing –C–F– F– clusters form stable plasma. By...
Effective segmentation of cervical cancer tissue from magnetic resonance (MR) images is crucial for automatic detection, staging, and treatment planning cancer. This study develops an innovative deep learning model to enhance the lesions. We obtained 4063 T2WI small-field sagittal, coronal, oblique axial 222 patients with pathologically confirmed Using this dataset, we employed a convolutional neural network (CNN) along TransUnet models training evaluation tissues.

It is of great significance for fluid management under microgravity to explore the morphological characteristics annular bubbles in a tank with central column. The propellant residue can be evaluated by measuring bubble's volume, and estimation mass center tanks also needs know liquid distribution. An experiment cabin designed experiments filling emptying model are carried out aboard Chinese Space Station. Two kinds surrounding column observed experimentally first time, which appear during...
Aqueous supercapacitors (SCs) are highly desirable as the next generation of energy storage devices, holding promise being environmentally friendly and free safety concerns. However, their low water-splitting voltage prevents practical applications. Here, we utilize a dielectric-polymer-coated, hierarchically structured carbon electrode to prepare dielectric-electrolyte SC (DESC), which exhibits an ultra-high stable operating 3 V. The facile design polymeric superstructure, covalently bonded...
