Electroforming and electron emission in metal-borosilicate glass-metal structures
… properties of thin co-evaporated SiO/B2C3 (borosilicate) films in the form of sandwich structures of M-SiO B203 –M (diode) and M-SiOx/B2O3-N-SiOx/B2O3-M (triode) have been studied. Diode and triode systems show electroforming effects and subsequently electron emission, voltage-controlled …

Phosphate-doped borosilicate enamel coating used to protect reinforcing steel from corrosion
<p>"Phosphate-doped sodium borosilicate glasses were developed for enamel coatings to provide corrosion protection for reinforcing steel in concrete. Phosphates have low solubilities in borosilicate glasses, generally less than about 4 mol%, and are incorporated mainly as isolated …

Process Characterization of the Reactive-Ion Etching of Borosilicate Glass for Microfluidic Channels
… characterize the process for the dry etching of borosilicate glass for microfluidic channels. Etch rate and surface roughness were studied, with partial pressure ratio (SF6:O2) and RF power as the factors. After formulating a DOE, the glass wafers were etched, with aluminum as the etching mask. …

Effects of radiation damage and composition on phase separation in borosilicate nuclear waste glasses
… and stability of $\textit{CaMoO4}$ in a borosilicate glass against the attack of internal radiation was investigated. It is a fundamental study that simplified the composition to known contributors of molybdate speciation, and further splits the com- ponents of α and β-decay into integral …

Dynamic response of glass under low-velocity impact and high strain-rate compression loading
… experimentally. Soda Lime, Starphire, Borosilicate, and Fused Silica were characterized using a Dynatup 8250 drop weight impact test system, and a modified Split Hopkinson Pressure Bar (SHPB). In the low-velocity punch-shear experiment, similar trend has been observed for all glass …

Immobilization of radioactive materials in iron phosphate glass
… radioactive wastes considered incompatible with borosilicate glass. Wastes may be incompatible with borosilicate glass due to high phosphorus content (Hanford tank sludges), the presence of halides (CsCl and SrF<sub>2</sub> capsules), or large amounts of uranium (SNF).</p> <p>Between 20 and 60 …
