There are various kinds of cutting fluids, which include oils, oil-water emulsions, pastes, gels, aerosols (mists), and air or ...
The cost is similar to composite resin. It holds up better than GIC, but not as well as composite resin, and is not recommended for biting surfaces of adult teeth, [22] or when control of moisture cannot be achieved. [23] [24] Generally, RMGICs can achieve a better aesthetic result than conventional GICs, but not as good as pure composites.

As a result, full crowns and even bridges (replacing multiple teeth) can be fabricated with these systems.

In water purification, chalcogels have shown promise in absorbing the heavy metal pollutants mercury, lead, and cadmium from water. [103] Aerogels may be used to separate oil from water, which could for example be used to respond to oil spills. [104] [81] [76] Aerogels may be used to disinfect water, killing bacteria. [105] [106]
