Summary: A hydrophilic konjac glucomannan (KGM)/ hydrophobic ethyl cellulose (EC) film was prepared in an ethanol/water environment. The study found that higher ethanol usage enhanced the stability of the film-forming solution but did not improve the film properties. The ethanol content and evaporation affected the molecular interaction during film formation.

Summary: Magnetite is an iron-rich carrier that can enhance the activity and aggregation of anammox bacteria. In this study, different-sized samples from a granulation reactor were used, and it was found that larger granules had higher iron content and improved microbial cell density. The specific anammox activity increased with granule size, and the heme c content was also higher in larger granules. The extracellular polymeric substances (EPS) analysis showed differences in secretion intensity and protein structures among the different sizes. The relative abundance of Brocadia Sinica also increased with granule size. This study highlights the importance of in-depth EPS analysis beyond traditional yield and major content analysis.

Summary: A series of novel comb-like polymers were designed and successfully synthesized with different side chain lengths, showing significant internal hydrophobic effects in cement-based materials. These polymers can reduce water absorption and dry shrinkage rate, slow down the exothermic rate of cement hydration, and delay the exothermic peak, providing a promising alternative for enhancing durability and service life of cement-based materials.

Summary: This study investigates the wettability properties of two types of titanium surfaces structured by femtosecond laser. It is found that samples textured in air show superhydrophilic properties, while samples processed in vacuum exhibit an increase in water contact angle. The observed difference can be attributed to the partial oxidation of the titanium surface during laser structuring in air. High temperature annealing of vacuum-processed samples results in complete oxidation of the titanium surface, leading to the formation of a permanent hydrophilic surface.

Summary: This study investigated the performance and sulfur poisoning of different Pd-Pt catalysts in the selective hydrogenation of soybean oil-derived fatty acid methyl esters (FAMEs). The results showed that catalysts with larger Pd-Pt alloy particles and weaker acidity favored the selective hydrogenation to produce monounsaturated esters, while catalysts with smaller Pd-Pt alloy particles and stronger acidity favored the formation of saturated esters. The performance of the catalyst physically mixed with acidic support γ-Al2O3 did not deteriorate when using a feedstock containing sulfur.

Summary: This study used atomic force microscopy to investigate the morphology and interactions of interfacial nanobubbles (INBs) with different surfaces. It was found that the hydrophilic probe is essential for scanning the complete morphology of INBs, and a positive correlation between INB vertical height and applied force was observed. Additionally, the interaction between INBs and hydrophobic surfaces was significantly stronger compared to hydrophilic surfaces.

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: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

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.
