Nanofibrous glass/ceramic porous structures using high-temperature interface bonding

Interface Characteristics of Sapphire Direct Bonding for High-Temperature Applications

In this letter, we present a sapphire direct bonding method using plasma surface activation, hydrophilic pre-bonding, and high temperature annealing. Through the combination of sapphire inductively coupled plasma etching and the direct bonding process, a vacuum-sealed cavity employable for high temperature applications is achieved. Cross-sectional scanning electron microscopy (SEM) research of ...

Interface high-temperature superconductivity

Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects being introduced into the latter, similar to modulationdoping in the semiconductor supe...

Interface structures in GaAs wafer bonding: Application to compliant substrates

A High-Temperature Embedded Network Interface using Software Thread Integration

This document describes an experimental implementation of a communication network protocol bridge for a high-temperature (200° C / 392° F) application. The software uses a novel compilation technique called Software Thread Integration (STI) to interleave multiple real-time program threads for efficient concurrent execution, allowing an off-the-shelf, high-temperature, low-speed 8 bit microcontr...

Room Temperature Crystallization of Hydroxyapatite in Porous Silicon Structures

Porous silicon (PS) substrates, with different pore sizes and morphology, have been used to crystallize hydroxyapatite (HA) nano-fibers by an easy and economical procedure using a co-precipitation method at room temperature. In situ formation of HA nanoparticles, within the meso- and macroporous silicon structure, resulted in the formation of nanometer-sized hydroxyapatite crystals on/within th...
