Gallium ultramicroelectrodes for amperometric measurements in scanning electrochemical microscopy were fabricated by introduction of liquid Ga into drawn glass micropipets. Cyclic voltammetry of Ru(NH(3))(6)(3+) and the use of this species for SECM imaging is described. Double-barrel micropipet tips with a Ga amperometric electrode and an ion-selective (K(+)) potentiometric probe can also be co...
A high degree of target perfection is required to achieve optimum performance for inertial fusion implosions. Target design calculations indicate that nonuniformities in sphericity, concentricity, and layer thickness should be less than -5% and that rms surface roughness should be less than 1000 A.1 Typically, targets are supported using glass fibers or films, which constitute a significant dep...
The determination of gene expression patterns in three dimensions with cellular resolution is an important goal in developmental biology. However the most sensitive, efficient, and widely used staining technique for whole-mount in situ hybridization (WMISH), nitroblue tetrazolium (NBT)/5-bromo-4-chloro-3-indolyl phosphate (BCIP) precipitation by alkaline phosphatase, could not yet be combined w...
This report describes the construction of a 345 Gigahertz receiver system based on superconducting tunnel junctions. The junctions used are Niobium edge junctions, which are mounted in a waveguide mixer mount. Highest sensitivity occurs at 312 GHz with a measured receiver noise temperature of 275 K double sideband. Theoretical calculations and experimental results both indicate the likelihood o...
Methods: Following approval by the Icahn School of Medicine at Mount Sinai Institutional Review Board, a retrospective review was performed identifying patients who underwent unilateral breast reconstruction using a double pedicle DIEP flap by a single two-surgeon team. Data was collected on patient characteristics, pre-operative risk factors, and post-operative complications. Data was analyzed...
Use of plasticizers in the formulation of solid propellants especially double-base solid propellants is inevitable. Double base propellants are composed of nitrocellulose (NC) polymer. Plasticizers cause to increase flexibility, reduce viscosity and glass transition temperature. Energetic azido ester plasticizers are compatible with energetic binders in solid propellants. In this work, five dif...
Abstract Glass/steel adhesive joints are being used increasingly in the construction industry as they offer significant structural advantages over conventional mechanical fastener approaches. However, also known to be sensitive moisture diffusion into bondline, which reduces interfacial bonding strength for hybrid glass/steel substrates. The effect of on performance degradation has been success...
In this paper, a novel fracture mechanics test-setup was developed, implemented and applied for assessment of the fatigue delamination behavior glass/encapsulant laminates under superimposed mechanical stresses environmental influences. Double cantilever beam (DCB) specimens with glass substrates were prepared using ethylene vinyl-acetate copolymer (EVA) or polyolefin elastomer (POE) encapsulan...
Sediment cores from Carp Lake provide a pollen record of the last ca. 125,000 years that helps disclose vegetational and climatic conditions from the present day to the previous interglaciation (120–133 ka). The core also contained 15 tephra layers, which were characterised by electron-microprobe analysis of volcanic glass shards. Identified tephra include Mount St. Helens Ye, 3.69 ka; Mazama a...
