Summary: The high surface resistance of PMMA leads to poor antistatic performance. By modifying PMMA with the ionic antistatic agent TMA and using acrylic acid as a compatibilizer, the surface resistance of PMMA can be significantly reduced. In addition to the improved antistatic effect, the modified PMMA also maintains high transmittance and enhances mechanical properties and thermal stability.

Summary: Enhancing hydrophilicity of polymeric materials is crucial for achieving anti-adhesiveness. This study combined atmospheric plasma pre-treatment with UV grafting process to achieve durable surface modification on PET. The most effective conditions for atmospheric plasma process were found to be 15 kW power and 4 m/min speed, resulting in a reduction in contact angle from 70 +/- 6 degrees to approximately 30 degrees. However, the contact angle increased over time due to ageing and washing of the PET surface. Therefore, the plasma-pre-treated PET samples were further modified through a UV grafting process using NaAc and KAc, which exhibited contact angles of 8 +/- 3 degrees and 28 +/- 13 degrees respectively, and showed durability in ageing and washing tests. The anti-adhesive properties of the modified PET surfaces were evaluated using Escherichia coli expressing YadA, showing a reduction in bacterial adhesion by more than 90%.

Summary: This article describes a modified intrascleral fixation technique for repositioning single-piece rigid polymethyl methacrylate intraocular lenses (IOLs). The technique involves a small scleral incision for haptic externalization, placement of the IOL haptic in scleral tunnels, and the use of absorbable sutures. Follow-up examinations showed well-centered IOLs, improved spherical refraction, and unchanged intraocular pressure, corneal endothelium density, and total astigmatism.

Summary: This paper describes the surface modification of polytetrafluoroethylene (PTFE) through plasma treatment. By optimizing various parameters, such as active gases, RF power, distance between the plasma source and sample, and plasma duration, the hydrophobic nature of PTFE was successfully reduced. The results showed that using N-2 as an active gas in plasma treatment significantly improved the wettability of the PTFE membrane. Various surface characterizations were used to verify the modified PTFE surface, which revealed significant surface modifications but non-uniform fiber alignment and torn fibers in some areas.

Summary: In this study, we investigated the hydrophilic surface modification of SiOx containing amorphous hydrogenated carbon nanocomposite films (DLC:SiOx) through atmospheric oxygen plasma treatment. The modified films showed effective hydrophilic properties with complete surface wetting. The treatment process increased the surface roughness and changed the surface chemical states, leading to the enrichment of hydrophilic chemical bonds and removal of hydrophobic functional groups.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
