Brown planthopper(BPH) is one of the most serious and destructive insect pests of rice in most rice growing regions of the world. In this study, two major resistance genes against BPH have been identified in an Oryza rufipogon (Griff.) introgression rice line, RBPH54. Inheritance of the BPH resistance in RBPH54 was studied by screening the resistance in(More)
An improved hydrothermal process is developed to fabricate macroporous graphene monoliths (MGMs) using a soft template of organic droplets. The MGMs are constructed from closed-cell distorted spherical pores. This unique microstructure makes MGMs that have low weight densities, good electrical conductivities, and excellent elasticity with rapid recovery(More)
Graphene has a unique atom-thick two-dimensional structure and excellent properties, making it attractive for a variety of electrochemical applications, including electrosynthesis, electrochemical sensors or electrocatalysis, and energy conversion and storage. However, the electrochemistry of single-layer graphene has not yet been well understood, possibly(More)
Glutamate dehydrogenase (GDH) is a key enzyme that catalyzes the final reaction of the glutamine metabolic pathway, and has been reported implicated in tumor growth and metastasis. However, it’s clinical significance and role in colorectal cancer (CRC) pathogenesis is largely unknown. The expression of GDH was determined by qPCR, western blot and(More)
Reduced graphene oxide (rGO) ribbons with arbitrary lengths were prepared by dry spinning of the hydrogels of graphene oxide (GO) formed via thermal annealing GO dispersions, and followed by chemical reduction. These rGO ribbons are flexible, having ultrahigh tensile strengths of 582 ± 17 MPa, ultrahigh fracture energies of 18.29 ± 2.47 MJ m(-3), high(More)
Strain sensors with large stretchability, broad sensing range, and high sensitivity are highly desirable because of their potential applications in electronic skins and health monitoring systems. In this paper, we report a high-performance strain sensor with a fish-scale-like graphene-sensing layer. This strain sensor can be fabricated via(More)
We report an efficient and cheap strategy to construct strain sensors by assembling reduced graphene oxide (rGO) sheets onto human hairs. These sensors are small, light and robust, and can be shaped into different structures such as fibre, spring and network. They can be used to detect various deformations including stretching, bending and compression with(More)
