A fused hybrid enzyme of 8-hydroxygeraniol oxidoreductase (8HGO) from Gardenia jasminoides and iridoid synthase (ISY) from Catharanthus roseus significantly enhances nepetalactol and iridoid production.

The operation of 8HGO-ISY fusion enzymes can increase nepetalactol flux to iridoid biosynthesis, and the Gj8HGO-CrISY expression in Gardenia jasminoides indicates that seco-iridoids and closed-ring iridoids share a nepetalactol pool. Nepetalactol is a common precursor of (seco)iridoids and their derivatives, which are a group of noncanonical monoterpenes. Functional characterization of an 8HGO (8-hydroxygeraniol oxidoreductase) from Catharanthus roseus, a seco-iridoids producing plant, has been reported; however, the 8HGO from G.

Recent Advances in Mechanical Vibration Energy Harvesters Based on Triboelectric Nanogenerators.

With the development of autonomous/smart technologies and the Internet of Things (IoT), tremendous wireless sensor nodes (WSNs) are of great importance to realize intelligent mechanical engineering, which is significant in the industrial and social fields. However, current power supply methods, cable and battery for instance, face challenges such as layout difficulties, high cost, short life, and environmental pollution. Meanwhile, vibration is ubiquitous in machinery, vehicles, structures, etc.
