Summary: The research utilized supercritical CO2 (SCCO2) fluid treatment to enhance the performance of carbon nanotube thin-film transistor (A-CNT-TFT) memory elements, achieving significant results. The treatment led to a hysteresis window larger than 50% of the sweeping-voltage range in the transfer characteristics of A-CNT-TFTs, with the disappearance of hump effect and improved switching characteristics. SCCO2 treatment reduced defects in the dielectric layer and strengthened the connection between channel and gate dielectric, enhancing charge storage capacity.

Summary: This study investigates the effect of an additional floating electrode on the properties of an atmospheric pressure plasma jet with a cross-field electrode configuration. The experiments show that the presence of an additional floating electrode reduces the power required for the plasma jet to cross the nozzle and increases the jet length. The threshold power and maximum jet length depend on the width of the electrode. The analysis also reveals an improvement in the reactivity of the plasma plume due to the increased optical emission intensity and relative yield of ions in the presence of the additional floating electrode.

Summary: In this study, amino functionalized magnetic multi-walled carbon nanotubes (MMWCNT-NH2) were prepared via a facile one-pot solvothermal method, and their sorptive removal efficiency of the anionic dye Congo red (CR) from water was investigated. The composite with triethylenetetramine showed higher removal efficiency due to its higher content of amino groups. Characterization analyses confirmed its excellent magnetic separation property and successful introduction of amino groups on MMWCNTs. The adsorption process followed the pseudo-second-order kinetic model and a three-stage diffusion mechanism was observed. The adsorption performance of MMWCNT-NH2-3 showed significant improvement after amino functionalization, with a maximum adsorption capacity of 322.7 mg/g. Selective adsorption of anionic dye was achieved due to electrostatic attraction and electron donor-acceptor interaction. The prepared MMWCNT-NH2-3 exhibited excellent reusability performance and could be a promising adsorbent for the removal of anionic dye from wastewater.

Summary: Carbon nanotubes (CNTs) have attracted significant interest as functional materials due to their exceptional mechanical, electrical, thermal, and photoelectric properties. However, the strong Van der Waals force causes CNTs to agglomerate into crystalline bundles, hindering their potential applications. Effective dispersion strategies, such as covalent and non-covalent functionalization, have been proposed to overcome this challenge and improve the self-assembling characteristics of CNTs. Non-covalent modifications, including electrostatic interaction, 7C-7C stacking interaction, dipole interactions, Van der Waals interactions, hydrogen bond, and coordination, are particularly attractive for CNTs dispersion without disturbing their internal electronic structure.

Summary: The dispersion of carbon nanotubes and carbon nanofibers is a crucial step in the production of polymer-based nanocomposites, and it is a challenge due to the tendency of nanofillers to agglomerate. While the three-roll mill is an effective method for dispersion, it is time-consuming and limits industrial applications. The study aimed to establish an efficient ultrasonic dispersion process and compare it with the three-roll mill method, using rheological tests and image analysis to characterize dispersion quality and improve the process.

Summary: The relationship between swelling, theoretical Hansen solubility parameters (HSP), and membrane mass transfer channel has been a subject of controversy. A new parameter, Swell-Cavity Ratio (SCR), was introduced to characterize the changes in mass transfer channels before and after membrane swelling. Models of the relationship between SCR and HSP were successfully constructed for nanoporous glassy and rubbery membranes. Theoretical calculations accurately determine the influence of solvent on membrane mass transfer channel, enabling the selection of optimal membrane materials and pretreatment processes.

Summary: Membrane gas separation processes play a crucial role in achieving carbon neutral climate goals. CO2philic membranes offer excellent selectivity for separating gases with similar or smaller molecular sizes than CO2. However, the gas permeability of PEO membranes is often hindered by dense chain packing and crystallization. To overcome this, a molecular engineering approach was used to develop a unique PEO membrane with a hyperbranched chemical topology connection. This strategy effectively regulated the packing density of polymer chains and reinforced the free volume fraction, resulting in a PEO membrane with superior performance.

Summary: This study presents a proactive fouling prevention mechanism by decorating a membrane surface with wrinkled-pattern microparticles, which can effectively prevent fouling caused by migratory viscous crude oil. The microparticles create nanoscale wrinkled patterns that increase the contact area between the membrane surface and water molecules, expanding the steric hindrance between the oil molecules and membrane surface. This concept successfully inhibits the initial adhesion, migration, and deposition of oil, achieving efficient migratory viscous crude oil antifouling. This research opens pathways for the development of superwettable materials with diverse applications in the environment, energy, health, and other fields.
