In the injection moulding process the manufactured plastic components may carry asignificant amount of charge which has undesirable consequences in some applications e.g.in dry powder inhalers (DPI's). In high resistivity polymers, the charge may lie in the bulk ofthe material which prevents typical neutralizing procedures such as use of ionizers. Insteadof neutralizing the ...

This paper proposes compensated methods to cancel the effects of charge injection error on switched-current Divider Circuits. Algorithmic structures of current dividers are presented and the final charge injection error is evaluated for each Algorithm. So, compensated methods to cancel this error are proposed.

The effects of an artificial cyclohexyl base pair on the quantum yields of fluorescence and dynamics of charge separation and charge recombination have been investigated for several synthetic DNA hairpins. The hairpins possess stilbenedicarboxamide, perylenediimide, or naphthalenediimide linkers and base-paired stems. In the absence of the artificial base pair hole injection into both adenine a...

In this work, we investigate the charging and reliability of interlayer dielectric materials that are used in the fabrication process of advanced RF-MEMS switches. In particular, the charge stored on the surface of a dielectric and the dynamic of this charge at Nanometric scale are studied. More attention is given to the decay of the deposited charge by a variety of means: (1) surface conductio...

Efficient charge injection is critical for flexible organic electronic devices such as organic light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Here, we investigated conjugated polymer-wrapped semiconducting single-walled carbon nanotubes (s-SWNTs) as solution-processable charge-injection layers in ambipolar organic field-effect transistors with poly(thienylenevinylene-co-pht...

For high current synchrotron SIS it is crucial to improve the multiturn injection efficiency. We study active emittance exchange due to a second order (skew quadrupole) difference resonance which is modified by the presence of space charge. We start from an analytical expression for the coherent tune shift of this resonance and compared it with computer simulation for the SIS synchrotron lattic...

Privacy is a much discussed and politically charged topic in contemporary healthcare. Yet, studying the actual privacy practices of healthcare professionals and patients remains extremely challenging. In this paper we reflect on our experiences using qualitative methods in two projects on HIV care, the first researching internet use by a particular group of patients, and the second looking at i...

Spin injection in silicon and other semiconductors by purely electrical means is paramount for building spintronic devices. One of the methods is to inject spins from a ferromagnetic electrode. Recently, a robust spin injection from a ferromagnetic metal contact into a semiconductor has been performed at room temperature [1]. However, the magnitude of the spin accumulation signal obtained with ...

Charge injection/blocking layers play important roles in the performances of organic electronic devices. Their incorporation into light emitting transistors has been limitted, due to generally high operating voltages (above 60 V) these In this work, two hole blocking molecules are integrated tris-(8-hydroxyquinoline) aluminum (Alq3) based under voltage as low 5 V. The effects and electron injec...
