Identification and comparative genomic analysis of endophytic fungi in Bletilla striata and its potential for promoting militarine bioaccumulation.

Bletilla striata (Thunb.) Reichb.f is renowned for its traditional medicinal applications and a spectrum of pharmacological activities, which is intricately linked to militarine.

Analysis of Plastic Improvement and Interference Behavior in Current-Assisted Riveting of CFRP Laminates.

In order to improve the joint performance of a titanium alloy rivet connecting aircraft CFRP structure and promote the wide application of ordinary titanium alloy rivets in the aviation field, the ductility of a Ti45Nb rivet was improved using a current-assisted method in this paper. Through experiments, the mechanical behavior and temperature during the riveting process were monitored, and the variation rules of interference and damage were studied in detail. The results show that a current within 16.

Study on the effects of transverse ultrasonic vibration on deformation mechanism and mechanical properties of riveted lap joints.

In this paper, a new and special transverse ultrasonic vibration-assisted riveting (TUVR) system is developed to improve the plasticity and qualification of titanium alloy rivets. Comparing with conventional riveting (CR), the formed driven heads by TUVR are not only suffered from the riveting force and hole boundary constrain, but also the acoustic softening and dragging friction force. Consequently, to disclose the deformation mechanism and mechanical properties in driven head, a series of studies were carried out.
