Summary: A novel thermoplastic polyurethane (TPU) matrix composite was prepared by incorporating tetra-needle zinc oxide whisker (T-ZnOw) and molybdenum disulfide (MoS2) particles. The effect of T-ZnOw and MoS2 on frictional vibration behaviors was investigated through frictional vibration experiments. The results showed that T-ZnOw improved the anti-deformation property of the composite, while MoS2 reduced the friction excitation force, resulting in a lower coefficient of friction and eliminated high-frequency vibrations. The optimum particle composition of 6% T-ZnOw and 9% MoS2 provided a low coefficient of friction and excellent vibration reduction properties.

Summary: This study systematically analyzed the damage behavior of unidirectional fiber-reinforced shape memory polymer composites (SMPCs) and revealed the bending damage behavior through theoretical analysis, parameter expressions, and evolution laws. The results showed that decreasing fiber volume content and increasing thickness were more likely to cause matrix cracking damage, while fiber fracture would occur in the stretching region if the fiber volume content was below a certain value. The validity of the theoretical method was demonstrated through experiments, highlighting the significance of this work for the design and optimization of SMPC-based structures.

Summary: Poly-(n-butyl methacrylate) (PnBMA) is an important polymer in biomedical applications. This study investigates the stability of PnBMA thin films on silicon substrates immersed in nonsolvent aqueous incubation media, such as water and phosphate-buffered saline (PBS), at biologically relevant temperatures. Dewetting hole growth experiments indicate that the stability of PnBMA films decreases with the duration and temperature of incubation, and water incubation leads to greater instability than PBS incubation. The observations are explained by the increase in surface energy, the dominant polar interactions, and the plasticization effect of the incubation media on the PnBMA films.

Summary: This study investigates the impact of loading rate on the mechanical properties of HKUST-1 MOF crystals. It is found that the Young's modulus and hardness of HKUST-1 remain stable or decline with decreasing loading rate, but significantly decrease with increasing loading rate. Molecular dynamics simulations reveal that this anomalous loading rate dependence is due to the competition between the release and transfer of latent heat in the amorphous HKUST-1.

Summary: Austenite and duplex stainless steels are widely used in engineering due to their excellent combination of mechanical properties and corrosion resistance. However, fatigue failure still poses a threat to their structural integrity. This study compared the cyclic deformation behavior of fully-austenitic stainless steel 316L and duplex stainless steel 2205, revealing that 2205 primarily exhibited cyclic hardening, while 316L showed additional secondary hardening at larger strain amplitudes.

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.
