Summary: Argon (Ar) plasma surface modification and highly (1 1 1)-oriented nanotwinned copper (nt-Cu) were combined to lower the bonding temperature of Cu/SiO2 hybrid joints. The contact angle of water on SiO2 could be reduced from 22.6 degrees to 3.3 degrees after the plasma treatment. X-ray photoelectron spectroscopy (XPS) was used to analyze the SiO2 surfaces and the bonding strength of the joints was characterized through shear tests, achieving an excellent bonding strength > 35 MPa.

Summary: Etching of SiO2 is important in the production of silica glass components and semiconductor devices. Wet-etching with hydrogen fluoride (HF) solutions is commonly used, but faces issues with microstructure sticking during solution drying. To overcome this, a dry-etching technique with gaseous HF at high temperatures was developed. Interesting results showed that silicon thermal oxides were less etched than vitreous silica by gaseous HF, indicating a difference in surface species affecting the reaction rate.

Summary: Blending polymers with a high concentration of bio-based fillers can reduce dependency on petroleum-based feedstocks and decrease the carbon footprint. In this study, n-octadecyl isocyanate (ODI) molecules were grafted onto lignin particles to make them compatible with a copolyamide matrix. Different concentrations of the surface-modified particles were blended with a low-melting point copolyimide, resulting in improved mechanical properties of the biocomposites. The findings suggest that these newly developed biocomposites with a green content of up to 80% are attractive alternatives to petroleum-based plastics.

Summary: In this study, a high-strength oil-well cement was prepared with hybrid nanosilica (NS) and nanohexagonal boron nitride (h-BN) additives to reduce environmental pollution and extend the lifetimes of oil wells. The addition of NS/h-BN was found to enhance the mechanical strength of the cement. The optimal ratio of nanomaterials was determined to be 2.5 wt% NS and 0.5 wt% h-BN, resulting in increased compressive, flexural, and splitting tensile strengths compared to the blank group.

Summary: This paper presents a polymer/SiO2 hybrid waveguide micro-ring filter based on a short carbon nanotube (CNT) nano-film. The nano-film is coated on the top surface of the polymer waveguide, and both the nano-film and polymer waveguide serve as the core of the device. The nano-film effectively improves the coherent depth and quality factor values of the filter. The filter shows good all-optical tunable performance due to the excellent light absorption characteristic and large thermo-optic effect of the CNT nano-film.

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.
