Oxidization of diamond grits in diamond/borosilicate glass composites

open access: yesJin'gangshi yu moliao moju gongcheng, 2022
The oxidation reaction mechanism of diamond grits in diamond/borosilicate glass composites was studied. The composites were sintered at different conditions and the samples were analyzed through TG–DSC, XRD and Raman.

Reaction of quartz glass in lithium-containing alkaline solutions with or without Ca [PDF]

open access: yesRoyal Society Open Science, 2018
The exact role of lithium ions (Li+) in controlling alkali–silica reaction is still unclear. Thus, the effects of Li+ on the reaction between reactive silica (quartz glass) and hydroxyl in alkaline solution with or without Ca were investigated by quartz ...

A new strategy to fabricate YIG ferrite joint with novel magnetic Bi2O3-CoO-Fe2O3-B2O3 glass

open access: yesMaterials & Design, 2022
A new low-temperature magnetic Bi2O3-CoO-Fe2O3-B2O3 (BCFB) glass was designed to acquire magnetic yttrium iron garnet (YIG/YIG) joint. This paper investigated the thermal behavior of BCFB glass and its wettability on YIG.

Integrated assessment procedure for determining the fracture strength of glass components in CSP systems [PDF]

open access: yesFracture and Structural Integrity, 2014
The structural integrity and reliability of glass components are key issues for concentrated solar power (CSP) systems. For example, the glass windows in a solar furnace may suffer catastrophic fracture due to thermal and structural loadings, including ...

Thin film diffusion barrier formation in PDMS microcavities [PDF]

open access: yes, 2009
We describe a method to form glass like thin film barrier in polydimethylsiloxane (PDMS) microcavities. The reactive fragments for the surface reaction were created from O2 and hexamethyldisiloxane (HMDS) in RF plasma environment.

An all-glass microfluidic network with integrated amorphous silicon photosensors for on-chip monitoring of enzymatic biochemical assay [PDF]

open access: yes, 2017
A lab-on-chip system, integrating an all-glass microfluidics and on-chip optical detection, was developed and tested. The microfluidic network is etched in a glass substrate, which is then sealed with a glass cover by direct bonding.
