Summary: This study demonstrates the transformation of one type of superhydrophobic surfaces to another by changing surface topography alone, resulting in solid surfaces with tunable properties. The different surfaces, featuring gecko, petal, and lotus effects, were achieved by adjusting the roughness factor and length scale of roughness, while maintaining the same surface chemistry. The study investigates the behavior of water droplets on these surfaces, revealing similarities in spreading but differences in sliding, receding, jetting, and rebounding due to the variations in adhesive properties. The research also provides explanations for the different behaviors based on existing equations for surfaces with petal and lotus effects, while the surface with gecko effect is attributed to negative pressure generated by sealed air within its structure.

Summary: This study aims to produce a hydrophobic polymer film by mimicking the hierarchical micro/nanostructures found on the surface of rose petals. The presence of these structures on the polyurethane acrylate (PUA) film influenced its wettability behavior, leading to a highly hydrophobic surface.

Summary: In cut roses, auxin regulates flower opening by inducing the expression of RhMYB6, which controls petal cell expansion. RhARF2, an auxin response factor, interacts with the promoter of RhMYB6 to repress its transcription. Silencing of RhARF2 results in larger petals and delayed petal movement, with significant differences in ethylene-related gene expression. The study demonstrates that auxin-regulated RhARF2 plays a critical role in controlling flower opening through the regulation of RhMYB6 and the crosstalk between auxin and ethylene signaling.

Summary: Oxidative stress can lead to various pathological changes in cell and biological liquid properties, including cardiovascular and metabolic diseases. This study presents an effective, scalable, and inexpensive technique for manufacturing biomimetic SERS sensors to detect biomembrane oxidation. The technique utilizes rose petals as templates to create SERS substrates with a cavity structure, allowing for the capture and immobilization of blood cells. By covering the silicone replicas of rose petals with a thin Au film (100 nm) and spherical Au nanoparticles, SERS effect can be achieved in the microcavities, enabling the study of individual erythrocytes and early detection of membrane oxidation for diagnosis of blood and metabolic diseases.

Summary: In this study, a spraying pressure-tuning method was used to fabricate tunable adhesion superhydrophobic coating (TASC). The experiment demonstrated that by adjusting the spraying pressure, the surface morphology and roughness of TASCs could be controlled, thereby altering their wetting state towards water droplets. Additionally, the TASCs with different spraying pressure exhibited excellent anti-icing performance. This research holds significant importance in the design of materials with specific wetting and anti-icing properties.

Summary: This study focused on the formation of petal blotch in the rose cultivar 'Sunset Babylon Eyes' and found that only cyanidin 3,5-O-diglucoside (Cy3G5G) contributed to the blotch pigmentation. The amount of Cy3G5G varied at different developmental stages. Only flavonols but no flavone were found in blotch and non-blotch parts. Key enzyme genes and regulatory genes, such as RC7G0058400 (F3'H), RC6G0470600 (DFR), RC7G0212200 (ANS), RC7G0019000 (MYB), and RC1G0363600 (WRKY), were identified in the formation and color deepening of the blotch.

Summary: This paper investigates the effects of precession parameters on taper angle in microhole drilling of a nickel alloy. It shows that the incident angle, relative distance between the focuses of the precession and individual beams, and scanning speed all have significant impacts on the hole tapering. The optimal parameters to minimize tapering are suggested, and the mechanism is discussed. Precession laser machining offers advantages over conventional ultrashort pulse laser machining and has potential for various laser micromachining applications.

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.
