Bioactive glasses have been synthesized through methods such as conventional melting, quenching, the sol–gel process, flame synthesis, and microwave irradiation.The synthesis of bioglass has been reviewed by various groups, with sol-gel synthesis being one of the most frequently used methods for producing bioglass composites, particularly for tissue engineering applications.
In wet habitats, there is typically a drainage layer beneath the substrate to allow water to pool without saturating the substrate. [ 10 ] [ 2 ] The drainage layer may be constructed via coarse gravel, stones, expanded clay aggregate, or may be wholly synthetic; the drainage layer is typically separated from the overlying substrate with a fine ...
Bioactive metallic glass is a subset of bioactive glass, wherein the bulk material is composed of a metal-glass substrate and is coated with bioactive glass in order to make the material bioactive. The reasoning behind the introduction of the metallic base is to create a less brittle, stronger material that will be permanently implanted within ...
An aquarium (aqua = water) is a water-filled enclosure housing aquatic plants and/or animals such as fish. A bioactive aquarium would additionally house micro-organisms such as beneficial bacteria, and janitor animal species such as caridean shrimp, boxer shrimp, algae-eating snails and burrowing snails. At least one side of an aquarium is ...
The formation of neocartilage can also be induced with bioactive glass by using an in vitro culture of chondrocyte-seeded hydrogels and can serve as a subchondral substrate for tissue-engineered osteochondral constructs. [1] The borate-based bioactive glass has controllable degradation rates in order to match the rate at which actual bone is ...
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
Salter Science was a brand of science kits sold by Thomas Salter Ltd., a Scotland-based company which manufactured toys and science activity kits for children. [1] Kits included activities with electricity, microscopy, magnetism and crystal gardens, but the company is probably best known for their chemistry sets. The company also produced other ...
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
