The application of commercially available carbonate-based electrolytes to Li-metal batteries (LMBs) is challenging because the uncontrollable side reactions with Li anodes. Herein, a practical carbonate-electrolyte-based LMB high areal capacity and long cycle life proposed. cycling stability proposed established by applying an external compressive pressure (1200 kPa) boehmite-coated separator prevent short circuit electrodes. drives growth metal as dense uniform layer instead dendrites...
Hemispherical image sensors simplify lens designs, reduce optical aberrations, and improve resolution for compact wide-field-of-view cameras. To achieve hemispherical sensors, organic materials are promising candidates due to the following advantages: tunability of optoelectronic/spectral response low-temperature low-cost processes. Here, a photolithographic process is developed prepare sensor array using thin film photomemory transistors with density 308 pixels per square centimeter. This...

A new hybrid modeling method is proposed for the chip-package co-modeling and co-analysis. This designed to investigate simultaneous switching noise (SSN) coupling paths effects on dc output voltage offset of operational amplifier (OpAmp). It combines an analytical model circuit with a power distributed network (PDN) interconnection models at chip package substrate. In order validate model, CMOS OpAmp was fabricated using TSMC 0.25 mum. Then measured by sweeping SSN frequency from 10 MHz up...
Solution processing is an attractive alternative to standard vacuum fabrication techniques for the large-area manufacturing of metal oxide (MOx)-based electron devices.
