Summary: In this study, a 100 mu m thick Zinc coating was deposited on steel structures using arc and plasma arc thermal spray coating processes. The corrosion resistance performance of both coatings significantly increased over time, with plasma arc spraying showing a more uniform and dense morphology. This improvement is attributed to the blocking characteristics of stable hydrozincite on defects.

Summary: To accurately and comprehensively analyze the properties of organic nanopores in marine shale, an integration method using helium ion microscope (HIM), scanning electron microscope (SEM), focused ion beam-HIM (FIB-HIM), and FIB-SEM was proposed. Results showed that organic pores below 10 nm significantly impact shale gas storage and productivity evaluation by affecting porosity, surface area, pore size distribution, and connectivity characteristics. The integration method revealed an increase in surface porosity by 10.73% and an increase in specific surface area by 76%. It also showed that the formation of organic nanopores occurs in multiple stages, with larger bubble pores appearing during oil generation and smaller spongy pores appearing during gas generation. The organic pores revealed by FIB-HIM exhibited higher coordination numbers and a higher proportion of inner-connected volume, indicating more complex connectivity characteristics. Despite limitations, these novel insights highlight the importance of exploring organic nanopores at the nanoscale and have the potential to inform further research in this field.

Summary: In this study, we demonstrate an electron beam direct-write process in an aberration-corrected scanning transmission electron microscope. This process differs from conventional electron-beam-induced deposition techniques as it uses a different mechanism and elemental tin (Sn) as a precursor to enable atom-by-atom direct writing. The atomic-sized electron beam is used to generate chemically reactive point defects in a graphene substrate, allowing the precursor atoms to migrate and bond to the defect sites for deposition.

Summary: The Paris Agreement and the United Nation's 2030 Agenda for Sustainable Development are driving a global transition towards more sustainable, affordable, and reliable energy systems. This poses a challenge for the corrosion industry, as the development of climate-resilient energy systems and infrastructures requires considering the long-term behavior of structural materials, particularly metals and alloys. "Corrosion Challenges Towards a Sustainable Society" presents a series of cases that emphasize the importance of corrosion protection for metals and alloys in energy production, aiming to promote the understanding of corrosion science and raise awareness of the need for research and the consequences of corrosion in the public and political arenas.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.

Summary: In this study, 2-amino-5 mercapto-1,3,4-thiadiazole (ATT) was used as an intercalating agent to prepare ATT/BNNS nanofillers via a liquid-phase assisted ultrasound method. TEM results showed that ATT successfully exfoliated BNNS and reduced agglomeration. The WEP ATT/BNNS coating exhibited the best protective performance under saline immersion due to the combined action of ATT inhibitor and BNNS physical barrier.
