Flow systems for precise and accurate coulometric determinations of ions that were developed on the basis of electrolytic ion transfer at the aqueous|organic solution (W|O) interface are reviewed. The electrolysis cell in the system is composed of a porous poly(tetrafluoroethylene) tube (1.0 mm inner diameter), a metal wire (0.8 mm diameter) inserted into the tube, O into which the tube is imme...

We present techniques to analyze and alleviate cross-talk in on-chip buses. With rapidly shrinking process feature sizes, wire delay is becoming a large fraction of the overall delay of a circuit. Additionally, the increasing crosscoupling capacitances between wires on the same metal layer create a situation where the delay of a wire is strongly dependent on the electrical state of its neighbor...

The emission of dusts and gases, which are generated during tubular cored wire welding and which are hazardous to health and the environment, were studied. Tests included various kinds of tubular electrode wires used for welding steel, that is, rutile flux cored wires, basic flux cored wires, and metal cored wires for welding unalloyed, low-alloy, and high-alloy steels as well as self-shielded ...

Motivated by the need for understanding the boiling processes in three-phase microscopic systems, the present work aims to uncover the physics of forced dewetting of a liquid film initially attached to a metal wire frame, which is heated with a rate up to O(108) K s−1 by discharging a capacitor impulsively. Depending on the corresponding heat flux O(1011) J m−2, there are several key dewetting ...

Energetics and conductance in jellium-modeled nanowires are investigated using the local-density-functionalbased shell correction method. In analogy with studies of other finite-size fermion systems, e.g., simple metal clusters or 3He clusters, we find that the energetics of the wire as a function of its radius (transverse reduced dimension) leads to formation of self-selecting magic wire confi...

Unconstrained metal powders of chromium and nickel, in combination with aluminium, were used the submerged arc welding (SAW) process to simplify weld alloying. refer non-alloyed that are not constrained tubular wire, such as fluxed-cored metal-cored wire. Aluminium powder is control oxygen potential at molten flux–weld pool interface. The results presented here show addition aluminium enhances ...

BACKGROUND To compare in a prospective randomized study Mersilene tape and standard metal wire for complications and pain upon sternal wound closure. METHODS Sixty-four patients scheduled for cardiac surgery were prospectively randomized to undergo sternal closure using either Mersilene tape (n=30) or standard metal wire (n=34). The intensity of postoperative pain from the chest wound was ass...

Using density functional theory we perform theoretical investigations of the electronic properties of a freestanding one-dimensional organometallic vanadium-benzene wire. This system represents the limiting case of multidecker Vn(C6H6)(n+1) clusters which can be synthesized with established methods. We predict that the ground state of the wire is a 100% spin-polarized ferromagnet (half-metal). ...

Except for heating losses in metal, propagating plasmons also suffer a lot from radiation losses. In this paper, electron beams are proposed as a way to excite higher-order, multipolar plasmons, which would otherwise not be excited by light, as a way to reduce radiation losses. Specifically, electron excited guided plasmons in a coupled nanoparticle chain and a symmetrical four-wire waveguide a...

Novel metal oxide semiconductor field effect transistor (MOSFET) architectures aimed at sub IV operation with enhanced current driving capability are reported. In our design, the planar channel region in a conventional MOSFET is replaced by an array of isolated Si wires. Directional metal coverage of the two sidewalls and the top surface of each Si wire help achieve enhanced gate control. Sub I...
