It is certain that, at the temperature of 900掳, silver does give off some vapour, but we are convinced that no silver left the weighed tube. The silica tube was 17 cm. in length, not more than half of which was heated in the furnace. The rest, shielded from the heat of the ...

The first direct f–2f carrier envelope offset frequency measurement of a micro-comb was demonstrated using a fused silica micro-disc with an externally-broadened spectrum in a nonlinear fibre [285]. This result was achieved with a micro-comb with a 16 GHz repetition-rate. Both carrier ...
Chalk, magnesia, barytes, alumina and silica are highly stable oxygen-containing compounds; the high temperatures required to break them down could not be achieved in Lavoisier's time. (Magnesia, after all, is what fire brick is made of!) The proper classification of these substances was ...
A radiating plasma (equivalent black-body temperature of 6,000° K) consisting of argon and UF6 (uranium hexafluoride) has been successfully contained within a container of cooled fused silica without causing coating of the walls and transmitting over 90 per cent of the source radiation through ...

the at least one silicon precursor of Formula I or Formula II described herein comprise less than 2% by weight, or less than 1% by weight, or less than 0.5% by weight of one or more of the following impurities: free amines, free halides or halogen ions, and higher molecular weight speci...
which forms a self-assembled monolayer (SAM) with siloxane bonds to the silicon surface. The amine groups of APTES in these functionalized systems then present a positively charged surface for attachment of sample molecules such as silica nanoparticles or carboxylated carbon nanotubes that are ...
Memristive devices are an emerging new type of devices operating at the scale of a few or even single atoms. They are currently used as storage elements and are investigated for performing in-memory and neuromorphic computing. Amongst these devices, Ag/a
