Among anode materials for sodium ion batteries, red phosphorus is a very promising one due to its abundant reserves, low-cost and high theoretical capacity of 2600 mA h g-1. However, its huge volume expansion on sodiation (∼490%) and poor conductivity leads to dramatic capacity decay, restraining its practical application. To improve the electrochemical performance, here, we prepared a red phosphorus and graphene nanoplate composite using cheap red P and natural graphite as the starting materials via a simple and scalable ball-milling method. The phosphorus-carbon bond formed during the milling process improves the electrical connectivity between P particles and graphene nanoplates, …

PbTe-based thermoelectric materials are good candidates for harvesting waste heat at mid-range temperatures due to their high thermoelectric efficiencies. Excellent quality and reliability of the bonding between the thermoelectric material and the electrode at high temperatures are essential for manufacturing thermoelectric generators. Here, a technique has been developed to achieve high-quality bonding between PbTe and the electrode. We have successfully performed one-step sintering of nickel electrode to n-type PbTe powder using spark plasma sintering. The fabricated interphase, composed of nickel telluride, is continuous and homogeneous across the junction, without visible flaws on the electrode or in the interphase and PbTe. …

Photochemical tissue bonding (PTB) is a promising sutureless technique for tissue repair. PTB is often achieved by applying a solution of rose bengal (RB) between two tissue edges, which are irradiated by a green laser to crosslink collagen fibers with minimal heat production. In this study, RB has been incorporated in chitosan films to create a novel tissue adhesive that is laser-activated. Materials and Methods. Adhesive films, based on chitosan and containing ∼0.1wt% RB were manufactured and bonded to calf intestine by a solid state laser (wavelength =532nm, Fluence ∼110J/cm2, spot size ∼5 mm). A single-column tensiometer, interfaced with a …

The asymmetric unit of the title salt, 2NH4+_B10H102__1.5H2O or (NH4)2B10H10_1.5H2O, (I), contains two B10H102_ anions, four NH4+ cations and three water molecules. (I) was converted to the anhydrous compound (NH4)2B10H10, (II), by heating to 343 K and its X-ray powder pattern was obtained. The extended structure of (I) shows two types of hydrogen-bonding interactions (N-H_ _ _O and O-H_ _ _O) and two types of dihydrogen-bonding interactions (N- H_ _ _H-B and O-H_ _ _H-B). The N-H_ _ _H-B dihydrogen bonding forms a two-dimensional sheet structure, and hydrogen bonding (N-H_ _ _O and O-H_ _ _O) and O- H_ _ …

A world-first nation-wide community website scheme was established in Australia in 2006 to enhance existing, and build new, social networks within geographic communities. By doing so, it sought to promote geographic community engagement. Initially, this paper presents an overview of the scheme since its inception and review the current geographic community groups participating in the scheme. To date the scheme has had limited success in attracting a critical mass of communities that value the promoted benefits of social networks in this format, with only 154 community websites across Australia. While it has not achieved the expected level of uptake, the …

In the crystal structures of the two imidazole derivatives 5-chloro-1,2-dimethyl-4-nitro-1H-imidazole, C5H6ClN3O2, (I), and 2-chloro-1-methyl-4-nitro-1H-imidazole, C4H4ClN3O2, (II), C—Cl...O halogen bonds are the principal specific interactions responsible for the crystal packing. Two different halogen-bond modes are observed: in (I), there is one very short and directional C—Cl...O contact [Cl...O = 2.899 (1) Å], while in (II), the C—Cl group approaches two different O atoms from two different molecules, and the contacts are longer [3.285 (2) and 3.498 (2) Å] and less directional. …
