Abiotic stresses, such as drought and high salinity, are major factors that limit plant growth and productivity. Late embryogenesis abundant (LEA) proteins are members of a diverse, multigene family closely associated with tolerance to abiotic stresses in numerous organisms. We examined the function of SmLEA2, previously isolated from Salvia miltiorrhiza, in defense responses to drought and high salinity...
In this work, single-walled carbon nanotube/amorphous indium gallium zinc oxide (SWNT/a-IGZO) composite thin film transistors (TFTs) have been realized by a simple sputtering method for the first time. Effect of the embedded single-walled carbon nanotube (SWNT) concentration on the electrical properties of the composite TFTs has also been investigated. The composite TFTs show better electrical performance...
The effect of annealing treatment on the device performance of carbon nanotube thin film transistors (CNT-TFTs) have been investigated systematically. The optimized annealing temperature has been found out from the tradeoff between source-drain total resistance and on-off current ratio, resulting in high-performance CNT-TFTs with a typical Ion/Ioff larger than 106, a subthreshold swing as low as 140...
A type of half-embedded cone grating nanostructure is proposed for antireflection (AR). It can achieve reflectance of down to 0.5% under normal incidence and 6% under incidence angle as large as 40 degrees in the 300–1100 nm wavelength range. Besides, it can maintain good performance in a large dimension range with a fixed period or vertex angle. Furthermore, the refractive index of the grating can...
A simple and effective method to control the growth of carbon nanotubes (CNTs) by introducing 0-dimensional silica particles has been proposed and demonstrated. After being processed with dip-coating and self-assembly of the specific silica nanoparticles, the substrate surface with nano-scale morphology was obtained, and which helped to control the diameters and density during the CNTs growth in a...
One type of nanoring reflectarray metasurface is demonstrated to achieve high-efficiency beam steering in anomalous reflections. Rings with varied inner radius are designed to manipulate the phase front of the incident wave. The efficiency of anomalous reflections achieves more than 80% at the reflection angle of 53° under normal incidence. The light reflects along the surface of structure when the...
We fabricated indium gallium zinc oxide - carbon nanotube composite thin film transistors (IGZO - CNT TFTs) by a simple sputter method. The device performed comparable electrical properties with an on current of 95µA under the drain voltage of 20V. The on/off ratio reached 105. With the CNT embedded into IGZO, the threshold voltage has been improved to 3.4V from 10.8V of IGZO TFT fabricated under...
Salinity and drought are important abiotic stresses limiting plant growth and development. Late embryogenesis abundant (LEA) proteins are a group of proteins associated with tolerance to water-related stress. We previously cloned an LEA gene, SmLEA, from Salvia miltiorrhiza Bunge. Phylogenetic analysis indicated that SmLEA belongs to Group LEA14, which is involved in the dehydration response. To determine...
