Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

An 8‐bit digital‐to‐time converter with pre‐skewing and time interpolation

open access: yesIET Circuits, Devices and Systems, 2021
This study presents an 8‐bit delay line digital‐to‐time converter (DTC) with pre‐skewing and digital time interpolation. Pre‐skewing that lowers the per‐stage‐delay of delay lines beyond that set by the chosen technology is investigated.

Test-Signal Search for Mixed-Signal Cores in a System-on-Chip [PDF]

open access: yes, 2004
The well-known approach towards testing mixed-signal cores is functional testing and basically measuring key parameters of the core. However, especially if performance requirements increase, and embedded cores are considered, functional testing becomes ...

Analogue integrated-circuit design for sustainedneurons in a fly

open access: yesElectronics Letters, 2001
An analogue integrated-circuit design of a fly's sustained neurons is presented. Circuit simulation of the design shows that the output exhibits non-associative learning in agreement with electrophysiological studies of these neurons. The output is shown to encode the contrast of the input.
