Summary: This study investigates the influence of micro-region structural characteristic on the corrosion behavior of the dilute extruded Mg-0.5Bi-0.5Sn-0.5In alloy. The results show that the corrosion mode is determined by the presence of local crystallographic defects, while the long-term corrosion rate is controlled by grain orientation variation.

Summary: Cryo-electron microscopy (cryo-EM) is used to visualize the atomic structure of macromolecules in their native state by embedding them in thin ice. However, controlling the uniformity of ice thickness is a challenge in high-resolution cryo-EM. In this study, we found that using ultraflat graphene (UFG) as the supporting film improves control over vitreous ice thickness. We successfully determined the 3D structures of hemoglobin, alpha-fetoprotein, and streptavidin using this method.

Summary: Creep ageing of Al-Cu-Li alloys leads to precipitation of T1 and a high fraction of low-angle grain boundaries and dislocations which contributes to corrosion. Stress-induced fine dense precipitation of T-1 in grain interior and suppressed precipitation along grain/subgrain-boundary shift corrosion mode from intergranular to intragranular.

Summary: Orientation rotation at grain boundary regions in Fe-3.0 wt.% Si non-oriented silicon steel is investigated using crystal plastic simulation. The study reveals that the rotation tendency and rotation velocity field at grain boundary regions are significantly influenced by neighboring orientations. Control over deformation texture at grain boundary regions can be achieved by designing the initial texture based on the rotation influenced by neighboring orientations.

Summary: This study presents the results of deuterium permeation experiments through chemical vapor deposited graphene on copper, revealing the impact of intrinsic defects on permeation. The findings suggest that grain boundaries are not the main diffusion pathways in graphene, and other intrinsic defects exhibit less resistance to permeation.

Summary: The study investigates the growth of ultrathin Mo2C on an In-Cu alloy substrate using chemical vapor deposition and how synthesis parameters and substrate composition can affect the process. Increasing methane flow rates results in larger Mo2C flake sizes and the formation of graphene/Mo2C heterostructures. Higher In composition reduces surface coverage and coalescence but does not significantly impact Mo2C flake size.

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.
