The Au and C signals appear because the sample was fixed in resin and covered in gold.
Gel type resins are homogenous, have no discrete pores, the channels act as pores while macroporous resins are referred to as fixed pore resins.
Unfortunately, the comparison of in vitro cryo-electron microscopy data with cellular electron microscopy was done with chemically fixed and resin-embedded samples.
When fixing a sample, synthetic resin may be substituted by halide salts (i.e. potassium bromide, sodium chloride or silver chloride etc).
A silane coupling agent specific for each cement system was applied on resin-composite and porcelain surfaces before fixing on dentin slabs with resin cements.
This article describes a method of fabricating a metal-resin fixed complete denture using a cemented acrylic resin superstructure over a metal bar that is screw-retained.
First, samples were fixed into the resin without any protective layers to verify the infiltration of embedding resins into the layers of analysed sample.
Typical ion-exchange reactions can be written as follows: in which Res− stands for an ion fixed in the resin or other type of exchanger and A+ and B+ are univalent cations (monopositive ions) while C2+ is a divalent cation.
Smaller accessories are simple to makeover, too: picture frames, mirrors or candlesticks can be painted, gilded or decoupaged; chips in crockery fixed with epoxy resin; lampshades recovered... Shops won't take furniture that's in poor condition (or without a fire label, for example), so you can rely on a certain level of quality.
The annealed powders were then fixed in epoxy resin.
Implant was embedded into steel mold and fixed with epoxy resin (Araldite®, Nichiban, Tokyo, Japan).
