Summary: This study explores the impact of several wet etchants commonly encountered in the microelectronic industry on the surface chemistry of GaN on silicon. Phosphoric acid treatment is found to significantly modify the surface and enable the recovery of the surface morphology. The study proposes a promising treatment method for the recovery of good quality GaN surfaces after dry etching.

Summary: A micro-airflow array pressurization method is proposed to achieve high-precision laser etching of ITO glass. By using airflow positioning, the method can induce micro-deformation of the glass. The study shows that positive airflow pressure can form a uniform flow pressure distribution and central micro-deformation, leading to improved surface flatness.

Summary: Acids have been commonly used to treat glass surfaces for functional advantage, but detailed studies on the subtle changes in glass surface properties after treatment are rare. This study investigated the intrinsic surface properties of an alkaline-earth boroaluminosilicate glass immediately after exposure to different chemical formulations. The results showed that the properties of the topmost surface of the treated glass are highly dependent on the type and strength of the formulation used.

Summary: The research aimed to select components for a matting mixture to give glass a frosted effect. Cluster analysis and Pareto diagrams showed parameters affecting the chemical etching of glass, with profiles of approximated values and the usefulness of the analysis presented. HCl and NH4F were found to mat glass evenly, while Na2CO3 had little impact and higher BaSO4 concentration caused crystal formation.

Summary: Synthetic diamond crystallites were successfully etched by MnO2 powder, leading to changes in surface morphology and properties. The etching intensity of {100} and {111} planes increased with temperature, with {111} plane being more significantly etched. The etching mechanism involved a reaction between MnO2 and the C atom on the diamond surface.

Summary: The microstructure evolution and formation mechanism of lighting etched region (LER) during rolling contact fatigue (RCF) in M50 steel were systematically investigated. LER was found to be a type of microstructure degeneration caused by the accumulation of plastic strain. The study identified four stages of microstructure evolution during RCF in LER, with changes in dislocation density, grain boundaries, and micro-hardness.

Summary: The study investigates how a nanocavity titanium surface affects the viability and adhesion of human gingival fibroblasts (HGF-1) and its response to Porphyromonas gingivalis. The results showed that the nanocavity titanium surface inhibits adhesion of P. gingivalis and promotes the adhesion of gingival fibroblasts, demonstrating its potential as an effective antibacterial surface for dental implants.

Summary: By etching silver nanowires with different amounts of aqua regia, more hot spots can be formed, resulting in higher sensitivity and uniformity in SERS signals. The limit of detection and maximum enhancement factor obtained on the optimized substrate are both higher than those of smooth silver nanowires.

Summary: The study introduces chelating agents into the alkaline treatment of ZSM-5 zeolite, resulting in a shift in mesopore distribution to smaller dimensions. The chelating agents participate in the transition by complexing with OH- anions and released aluminum cations, expanding the shielding scope on the etched surface/interface of the zeolite.

Summary: This study investigates the effects of etching temperature and hydrofluoric acid concentration on the surface and mechanical properties of etched fiber surface. It is found that higher temperature and concentration result in rougher surface and lower mechanical properties. Under optimized etching conditions, the sensitivity of EFBGs is improved by reducing the fiber diameter, with smaller diameters demonstrating higher strain sensing performance.

Summary: We report on the growth of zinc oxide (ZnO) nanorods on plain zinc plates using a simple and environment-friendly hot water treatment technique. The chemically etched zinc surface resulted in thicker and more uniform ZnO nanorods compared to the non-etched zinc surface, making it suitable for the development of high-conversion-efficiency PSCs.

Summary: Sinter pastes for rapid and low-temperature die-attach bonding have been developed to enable sintering under a nitrogen atmosphere. The surface modifications in the paste formulation provide accelerated material transport, leading to improved sintering capabilities and achieving a bulk-like sintered microstructure with low porosity. The use of PEG600 during the sinter process effectively reduces copper oxides and results in a shear strength of 30 MPa at 275 degrees C for 1 minute.
