Low-voltage and high-performance field-effect transistors based on ZnSnO nanofibers with a ZrO dielectric.

One-dimensional (1D) nanofibers have been considered to be important building blocks for nano-electronics due to their superior physical and chemical properties. In this report, high-performance zinc tin oxide (ZnSnO) nanofibers with various composition ratios were prepared by electrospinning. The surface morphology, crystallinity, grain size distribution, and chemical composition of the nanofibers were investigated.

Nature-Inspired Capillary-Driven Welding Process for Boosting Metal-Oxide Nanofiber Electronics.

Recently, semiconducting nanofiber networks (NFNs) have been considered as one of the most promising platforms for large-area and low-cost electronics applications. However, the high contact resistance among stacking nanofibers remained to be a major challenge, leading to poor device performance and parasitic energy consumption. In this report, a controllable welding technique for NFNs was successfully demonstrated via a bioinspired capillary-driven process.

Electronic Devices Based on Oxide Thin Films Fabricated by Fiber-to-Film Process.

Technical development for thin-film fabrication is essential for emerging metal-oxide (MO) electronics. Although impressive progress has been achieved in fabricating MO thin films, the challenges still remain. Here, we report a versatile and general thermal-induced nanomelting technique for fabricating MO thin films from the fiber networks, briefly called fiber-to-film (FTF) process.

Production of herbicide-resistant sweet potato plants transformed with the bar gene.

Herbicide-resistant sweet potato plants were produced through biolistics of embryogenic calli derived from shoot apical meristems. Plant materials were bombarded with the vectors containing the beta-glucuronidase gene (gusA) and the herbicide-resistant gene (bar). Selection was carried out using phosphinothricin (PPT).

A possible role for NDPK2 in the regulation of auxin-mediated responses for plant growth and development.

Auxin plays many crucial roles in the course of plant growth and development, such as hook opening, leaf expansion and inhibition of mesocotyl elongation. Although its mechanism of action has not been clarified at the molecular level, recent studies have indicated that auxin triggers the induction of a number of genes known as primary auxin-responsive genes. Hence, the identification of the regulatory components in auxin-mediated cellular responses would help to elucidate the mechanism of the action of this hormone in plant growth and development.
