Construction of Carbon Nanotube-based Composite Membrane with Electron-ion Double Transfer Function and its Electrically Driven Ion Separation Performance

The construction of electroactive ion separation membranes with dual functions of electron and ion transfer is a key technology in the field of electronchemically switched ion permselectivity membrane (ESIPM) separation. In this paper, CNT/CNF composite membranes with three-dimensional porous structure in submicron scale were prepared by blending and filtration of conducting carbon nanotubes (CNT) and cellulose nanofibers (CNF). Using CNT/CNF composite membranes as conductive base membrane, the S...

Research and Progress of Artificial Intelligence in Medical CT Image Reconstruction

Computed tomography (CT) is a medical image widely used in clinical medicine that visualizes the fine structural details inside human body. In clinical practice, to prevent the tissue damage caused by patient exposure to high-radiation X-ray beams, X-rays are usually minimized to obtain CT images, which results in a severe deterioration in imaging quality. To solve the above contradictions, how to reconstruct CT images that meet clinical needs has become a challenging problem widely concerned by ...

Fenton-like Degradation of Phenol over Fe3O4-CGGP

Magnetic geopolymer (Fe3O4-CGGP) was prepared from coal gangue, and evaluated by Fenton-like degradation of phenol. It was found that Fe3O4 with a particle size of 10-20 nm was uniformly dispersed on the surface of coal gangue geopolymer (CGGP). The saturation magnetization of Fe3O4-CGGP reached 35.68 emu/g. These indicated that Fe3O4-CGGP had a good catalytic activity and magnetic responsiveness. The effects of pH value, catalyst dosage, H2O2 dosage, and initial phenol concentration were investi...
