Towards multistep nanostructure synthesis: programmed enzymatic self-assembly of DNA/gold systems
No full textThe programmed self-assembly of nanostructures from well-defined units is an important aim in nanoscience.[1], [2] The use of gold nanoparticles stabilized by thiol-modified DNA is a promising approach towards this goal.[3]-[8] The specificity of DNA base-pairing provides a precise means of programming interactions between particles by hybridization with specifically designed linker strands. To introduce an additional level of control, we have developed a general method by which the reactivity of initially latent DNA linking sites can be switched on deliberately. We have adapted well-developed methods of molecular biology to produce a nanoscale analogue of protecting groups. We show that linking sites can be protected by hybridization with complementary strands and deprotected by cleaving these double strands at predetermined sites with restriction enzymes. This results in cohesive ends of single-stranded DNA, which can bind by hybridization to complementary sequences present in the system. In a second enzymatic step the DNA phosphodiester backbones at the hybridization sites are covalently joined using a DNA ligase. This approach represents a generic protocol that will enable multistep nanostructure syntheses

Intersubband Transition in GaN/InGaN Multiple Quantum Wells
No full textUtilizing the growth temperature controlled epitaxy, high quality GaN/In0.15Ga0.85N multiple quantum wells designed for intersubband transition (ISBT) as novel candidates in III-nitride infrared device applications have been experimentally realized for the first time. Photo-absorption originated from the ISBT has been successfully observed at infrared regime covering the 3-5 mu m atmosphere window, where the central absorption wavelength is modulated by adjusting the quantum well width. With increasing the quantum well thickness, the ISBT center wave length blue shifts at thickness less than 2.8 nm and then redshifts with further increase of the well thickness. The non-monotonic trend is most likely due to the polarization induced asymmetric shape of the quantum wells.National Basic Research Program of China [2012CB619300, 2013CB632800]; National Natural Science Foundation of China [61225019, 61376060, 61411130214]; National High Technology Research & Development Project of China [2014AA032606]; Beijing Municipal Science and Technology Project [Z131100005913001]SCI(E)[email protected]; [email protected]

Hahnia corticicola: 16 females, 17 males, CHINA: Sichuan: Jiuzhaigou County, Longkang Town (SWUC); 1 female, 1 male, Shaanxi: Zhouzhi County, Houzhenzi (SWUC). Etymology. The specific epithet refers to the species’ similarity to H. corticicola Bösenberg & Strand 1906. Diagnosis. The new species is similar to H. corticicola (Figs 3 A–I) in having similarly shaped patellar apophysis, RTA, median apophysis, tegulum, and long and deep cymbial furrow as well as a similarly positioned copulatory opening, but it can be distinguished by the pointed apex of the male palpal cymbium, the equally long cymbium and cymbial furrow, the presence of a small tegular apophysis near the base of the embolus, the extremely slender embolus with its tip embedded in a pocket (Figs 1 A–C, 2 E–G), the protruding median part of the posterior margin of the copulatory opening, the long, multi-coiled copulatory ducts and the distinct subspermathecae of the epigyne (1 D–E, 2 H–I). Description. Male holotype (Figs 2 A, C–D) total length 1.77. Prosoma 0.78 long, 0.68 wide; opisthosoma 1.09 long, 0.81 wide. Carapace pear-shaped with dark markings in radial furrows and cervical groove. Fovea longitudinal, brown. Cephalic area elevated. Eight eyes with distinct black rims. Eye sizes and interdistances: AME 0.03, ALE 0.06, PME 0.05, PLE 0.05; AME–AME 0.03, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.02, ALE–PLE 0.01. MOA 0.12 long, front width 0.09, back width 0.14. Clypeus height 0.12. Chelicerae yellowish with three promarginal and three retromarginal teeth. Gnathocoxae of equal length and width. Labium wider than long. Sternum cordiform with dark marginal markings. Legs yellow with some spines. Leg measurements: I 2.25 (0.66, 0.75, 0.48, 0.36); II 2.11 (0.63, 0.68, 0.44, 0.36); III 1.95 (0.55, 0.62, 0.44, 0.34); IV 2.41 (0.67, 0.79, 0.56, 0.39). Leg formula: 4123. Opisthosoma oval, greyish black with a light quadrate and five light chevrons dorsally. Tracheal spiracle equidistant between the epigastric furrow and the base of spinnerets. Male palp (Figs 1 A–C, 2 E–G) with a hook-like, relatively thin and long patellar apophysis. Distal part of RTA filiform extending dorsally and then proximally. Cymbium with a very deep, long and semi-transparent retrolateral furrow. Embolus originating retrolaterally, clockwise curved along the cymbial margin, then anticlockwise curved inside the cymbial furrow. End of embolus embedded in a transparent pocket. Median apophysis membranous, located near the base of embolus. One female paratype (collected with holotype, Fig. 2 B) total length 2.03. Prosoma 0.81 long, 0.59 wide; opisthosoma 1.26 long, 0.95 wide. Eye sizes and interdistances: AME 0.04, ALE 0.05, PME 0.05, PLE 0.05; AME– AME 0.02, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.03, ALE–PLE 0.01. MOA 0.13 long, front width 0.09, back width 0.13. Clypeus height 0.09. Leg measurements: I 1.96 (0.59, 0.66, 0.39, 0.32); II 1.83 (0.57, 0.59, 0.37, 0.30); III 1.72 (0.54, 0.54, 0.37, 0.27); IV 2.28 (0.66, 0.75, 0.50, 0.37). Leg formula: 4123. Epigyne (Figs 1 D–E, 2 H–I) with a pair of small copulatory openings medio-posteriorly with posterior margins visible. Copulatory ducts quite long and strongly convoluted as three coils. Subspermathecae located anteriorly, visible in the gap of copulatory duct loops. Spermathecae located centrally in the loops of copulatory ducts. Fertilization ducts extending posteriorly and curving medially. Distribution. China (Chongqing, Hubei, Anhui) (Fig. 4). Remark. The new species was collected in the leaf litter of an old-growth forest area, specifically, along the Yangtze River basin, close to the latitude 30 ° North.Published as part of Liu, Na, Huang, Gui-Qiang & Zhang, Zhi-Sheng, 2015, A new species of the genus Hahnia (Araneae: Hahniidae) from South China, pp. 295-300 in Zootaxa 3994 (2) on pages 295-299, DOI: 10.11646/zootaxa.3994.2.10, http://zenodo.org/record/24032
