Summary: The study found that both annealing and solution aging can improve the mechanical properties of CSAMed AA2024/Al2O3 composite, with solution aging slightly better than annealing. After heat treatment, the fracture mechanism between adjacent particles changed, but the interfacial bonding between AA2024 and Al2O3 particles could not be improved.

Summary: Dense and thick 7075 Al deposits were prepared using cold spray additive manufacturing (CSAM). Different heat treatments were applied to investigate the inherent anisotropy of the deposits. Microstructural and mechanical anisotropy was characterized using SEM, EBSD, Vickers micro-hardness tests, and tensile tests. The results showed that heat treatments did not eliminate microstructural anisotropy, although secondary phases preferentially nucleated at particle-particle interfaces. Mechanical anisotropy could be alleviated but not completely eliminated. The T6 sample exhibited the highest ultimate tensile strength and microhardness due to precipitation hardening. Sintering treatment greatly improved the elongation of CSAMed Al deposits.

Summary: In this study, NiCoCrAlTaY coatings were prepared on cobalt-based superalloy substrates by high pressure cold spray technology, and their microstructure, mechanical property, and tribological behaviors were systematically studied before and after thermal exposure at 1050 degrees C. The results showed that NiCoCrAlTaY coatings with a very dense structure could be obtained by high-pressure cold spraying. The coating remained completely intact without any cracking and spalling after thermal exposure. However, the wear resistance of the coating significantly decreased after thermal exposure with a decrease in hardness and an increase in friction coefficient and volume wear rate.

Summary: In this study, PLA/P(3HB-co-4HB) blends were successfully prepared using a melt plasticization equipment based on elongational flow field (EFF), and MWCNT was introduced to obtain PLA/P(3HB-co-4HB)/MWCNT high-performance alloy. EFF greatly enhanced the mechanical properties, HDT, thermal stability, and crystallization perfection of PLA. Additionally, EFF promoted the dispersion of MWCNT and played a "bridge" role between PLA and P(3HB-co-4HB).

Summary: Hybrid composites of glass fiber-reinforced composite (GFRC) and carbon fiber-reinforced composite (CFRC) provide lightweight construction and improved mechanical properties, but delamination at the interface due to thermal strain difference between materials is a concern. This study addresses the issue by using multi-walled carbon nanotubes (MWCNT) to optimize thermal strain and provide buffering effect. Experimental results show that the epoxy adhesive with 0.3 wt% MWCNT exhibits the best performance.

Summary: This study examines the formation mechanism of residual stresses in cold spray printing by investigating four major factors. It is found that heat input and heat transfer rate are key factors in controlling the sign of the residual stress. Experimental results show that desirable patterns of residual stress can be achieved by controlling parameters, leading to higher density and hardness, and lower roughness in compressive samples compared to tensile ones.

Summary: In this study, equiatomic CoCrFeNi high-entropy alloy was manufactured using solid-state cold spray additive manufacturing technology and then post-spray annealed at temperatures ranging from 500 to 1000 degrees C. Different types of deposits were obtained by adjusting the annealing temperature, and their microstructure and mechanical properties were examined. The as-sprayed deposit showed high compressive yield strength but fractured in the tensile test, indicating tension-compression asymmetry. Recrystallization annealing improved the deposit density and reduced interparticle interfaces, leading to enhanced compressive strength and ductility. Fully recrystallized deposit exhibited weakened tension-compression asymmetry and the best recovery of tensile ductility.

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: 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.
