A yield enhanced layout method for maximizing yield of integrated resistor networks with a fixed total area is discussed. This approach incorporates both random variations in the sheet resistance and random variations in the contact resistances. The concept of contact/sheet resistance crossover which gives the crossover between contact-resistance dominance and sheet resistance dominance is deve...

Micro-pattern gas detectors, such as the Gas Electron Multiplier (GEM) and the Micromegas need narrow high density anode readout elements to achieve good spatial resolution. A high-density anode readout would require an unmanageable number of electronics channels for certain potential micro-detector applications such as the Time Projection Chamber. We describe below a new technique to achieve g...

We have investigated Mn, Co and Ni substitution effects on polycrystalline samples of LaFePO0.95F0.05 by resistivity and magnetoresistance measurements. In LaFe1-xMxPO0.95F0.05 (M = Mn, Co and Ni), the superconducting transition temperature (Tc) monotonously decreases with increasing the impurity doping level of x. There is a clear difference of Tc suppression rates among Mn, Co and Ni doping c...

this study is considering a micropolar fluid flow over a porous stretching sheet in the presence of thermal radiation and uniform magnetic field. the effects of local variation in thermal conductivity of micropolar fluid on heat transfer rate from the sheet are investigated; besides, the impacts of radiation, magnetic field and porous sheet on variations of thermal boundary layer thickness are ...

Abstract Polytetrafluoroethylene (PTFE) polymer is used extensively in industry as a solid lubricant because of its lack reactivity with most industrial materials. However, PTFE has low abrasive resistance, limiting application. In this study, the mechanical and tribological characteristics PTFE-based composites addition clay nano-sheets (CNSs) were investigated. Clay nano-sheet-PTFE (CNSTCs) c...

Environmental, health, and safety (EHS) concerns are receiving considerable attention in nanoscience and nanotechnology (nano) research and development (R&D). Policymakers and others have urged that research on nano's EHS implications be developed alongside scientific research in the nano domain rather than subsequent to applications. This concurrent perspective suggests the importance of early...

because of production process and constrains conditions, circular graphene sheet may be opposed to structural defect and pin hole, respectively. some of the defects and pin hole on a circular graphene sheet can be considered as an eccentric hole on the sheet. hence, analyzing behavior of circular graphene sheet with an eccentric hole is important. free vibration of an eccentric annular graphene...

This paper describes the main results obtained from a detailed experimental investigation into dislocation and twinned structures that develop in dual phase (DP) steel sheets. In particular, morphology defect-structures present DP 1180 having 55% ferrite 45% martensite, were examined using transmission electron microscopy (TEM). Microstructure of as-received consists twin-free martensite form l...

Artificial confinement of electrons by tailoring the layer thickness has turned out to be a powerful tool harness control over competing phases in nano-layers complex oxides. We investigate effect dimensionality on transport properties $d$-electron based heavy-fermion metal CaCu$_{3}$Ru$_{4}$O$_{12}$. Transport behavior evolves from metallic localized regime upon reducing and insulator transiti...
