Summary: In this study, near-fully dense CrCoNi medium-entropy alloy coatings were successfully deposited on an AISI 1045 steel substrate via laser cladding. The microstructure formation, corrosion properties, and tribological properties were investigated. The CrCoNi coating exhibited a single-phase face-centered cubic structure with columnar grains, and achieved cellular substructures and elemental segregation. Moreover, it showed enhanced corrosion resistance and tribological properties due to the multi-stage potentiodynamic polarization behavior and the ultrafine microstructures as well as high hardness.

Summary: TiC-graphene dual-reinforced Al matrix hybrid nanocomposites (AMHNs) were synthesized using powder metallurgy. The microstructures, compressive properties, and tribological properties of the AMHNs with varying fractions of graphene nanoplatelets (GNPs) were investigated. The results showed that the addition of GNPs homogenized the microstructures and distributions of TiC and GNPs, resulting in improved compressive and wear resistance properties. The composite with 5.0 wt% TiC and 1.0 wt% GNPs exhibited the highest wear resistance with a wear rate reduction of 94.4% compared to the unreinforced Al alloy.

Summary: CuAlFeNi alloys are commercially important due to their different phase transitions and properties. The stability of phases in the Cu-10.79 wt%Al-4.42 wt%Ni-3.67 wt%Fe alloy was investigated after slow cooling and unidirectional solidification. It was found that Ni and Fe increased the stability of the b phase, and the alloy showed a higher fraction of the a phase after unidirectional solidification compared to slow cooling. The corrosion resistance of the alloy was also found to depend on the position of the sample relative to the heat exchange surface.

Summary: The effect of doping ceramic reinforcing particles during laser cladding technology has been rarely studied for amorphous alloy coatings. A crack-free Fe-based amorphous/crystalline composite coating with good tribological properties was successfully prepared on the surface of 40Cr steel by varying the content of WC-14Co addition. The addition of WC-14Co particles led to the suppression, disappearance, and reformation of cracks, ultimately achieving a crack-free state at 5 wt% addition.

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.

Different levels of nanoporosity were prepared and tested to investigate the sensing properties, and it was found that nanoporous black gold is suitable for hydrogen sensing. The sensitivity of the film depends on its nanoporosity.

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.
