Abstract

Litchi exhibits a large number of flowers, many flowering batches, and an inconsistent ratio of male and female flowers, frequently leading to a low fruit-setting rate. Floral sexual differentiation is a crucial phase in perennial trees to ensure optimal fruit production. However, the mechanism behind floral differentiation remains unclear. The objective of the study was to identify the role of auxin in floral differentiation at the transcriptional level. The results showed that the ratio of female flowers treated with naphthalene acetic acid (NAA) was significantly lower than that of the control stage (M0/F0). The levels of endogenous auxin and auxin metabolites were measured in male and female flowers at different stages of development. It was found that the levels of IAA, IAA-Glu, IAA-Asp, and IAA-Ala were significantly higher in male flowers compared to female flowers. Next-generation sequencing and modeling were employed to perform an in-depth transcriptome analysis on all flower buds in litchi 'Feizixiao' cultivars (Litchi chinensis Sonn.). Plant hormones were found to exert a significant impact on the litchi flowering process and flower proliferation. Specifically, a majority of differentially expressed genes (DEGs) related to the auxin pathway were noticeably increased during male flower bud differentiation. The current findings will enhance our comprehension of the process and control mechanism of litchi floral sexual differentiation. It also offers a theoretical foundation for implementing strategies to regulate flowering and enhance fruit production in litchi cultivation. [ABSTRACT FROM AUTHOR]

Abstract

For 4H-SiC mosfets, the parasitic PiN body diode causes problems such as significant forward voltage drop of body diode and poor reverse recovery characteristics during high-temperature operation. A reasonable solution is a mosfet with an integrated Schottky barrier diode to deactivate the PiN body diode. Since SiC mosfets can operate at extremely high temperatures, the characterization of electrical parameters at high temperatures and changing with the temperature are very important for high power applications and system reliability. However, there is a lack of comparison and analysis of the two devices on electrical properties at ultrahigh temperatures. In this article, a 1.2 kV conventional mosfet and a mosfet integrated with a junction barrier Schottky diode (JBSFET) were fabricated with a consistent process flow. In the temperature range from 300 to 575 K, analytical models of the temperature-dependent electrical parameters of these two devices were established and compared, which were successfully verified by the measurements. These models can provide guidance for ultrahigh temperature applications of JBSFETs. Temperature-related expressions can also be used for junction temperature monitoring of temperature-sensitive electrical parameters. Experimental results show that JBSFET has better third quadrant conduction characteristics and higher temperature stability below 450 K, but loses obvious performance advantages at 575 K. So, the recommended operating temperature range of JBSFET is from 300 to 450 K. Finally, the continuous operation performance of the body diodes in buck converters is analyzed. The higher efficiency of buck converter based on JBSFET's body diode indicates its great application potential in compact converters, especially in the recommended temperature range.

Abstract

Superhydrophobic surfaces are of great interest because of their remarkable properties. Due to its maximal hardness and chemical inertness, diamond film has great potential in fabricating robust superhydrophobic surfaces. In the present study, an oxygen-terminated polycrystalline boron-doped diamond (O-PBDD) superhydrophobic surface with micro/nano-hierarchical porous structures is developed. The preparation method is very simple, requiring only sputtering and dewetting procedures. The former involves sputtering gold and copper particles onto the hydrogen-terminated polycrystalline boron-doped diamond (H-PBDD) to form gold/copper films, whereas the latter involves placing the samples in an atmospheric tube furnace to form hierarchical pores. By controlling the etching parameters, the wettability of the O-PBDD surface can be adjusted from hydrophilic to superhydrophobic, which is significantly different to the normal hydrophilicity feature of O-termination diamonds. The water contact angle of the obtained O-PBDD surface can reach 165 ± 5°, which is higher than the superhydrophobic diamond surfaces that are reported in the literature. In addition, the O-PBDD surface exhibits excellent durability; it can maintain satisfactory superhydrophobicity even after high-pressure, high-temperature, and sandpaper friction tests. This work provides a new research direction for fabricating robust superhydrophobic materials with diamond film., (© 2024 Wiley‐VCH GmbH.)
