Chemicals such as dyes, stains, or fixatives are commonly used in specimen preparation to make them more visible under a microscope. Dyes bind to specific cellular components, stains highlight certain structures, and fixatives preserve the specimen's morphology for observation.
Crosslinking is the process by which adjacent chains in a polymer are joined together, forming a network of interconnected chains. This crosslinking enhances the strength and durability of the polymer by reducing flexibility and increasing resistance to breakage.
Some common fixatives in cosmetics include cyclomethicone, glyceryl stearate, and dimethicone. These ingredients help to improve the longevity and wear of makeup products by creating a barrier on the skin to prevent fading or smudging.
Gels can be classified based on their composition (organic or inorganic), structure (physical or chemical crosslinking), and origin (natural or synthetic). They can also be classified as hydrogels (water-based) or organogels (organic solvent-based).
PEX stands for Performance Excellence, which is a measurement of how well a student performs in their academic courses. It is often used as a grade in discussions around student performance and academic achievement.
Carnoy's fixative is a solution used in histology to preserve tissue samples for microscopy. It is a mixture of ethanol, chloroform, and acetic acid that helps to prevent decay and maintain the structural integrity of cells. Carnoy's fixative is particularly useful for preserving certain structures like chromosomes.
Hydrogels are made by crosslinking water-soluble polymer chains to create a three-dimensional network that can absorb water. This crosslinking can be achieved through physical or chemical methods. Physical methods include temperature changes or radiation, while chemical methods involve the use of crosslinking agents such as glutaraldehyde or ethylene glycol dimethacrylate.
Yes, some dyes require fixatives to help the color adhere to the fabric or material. Additionally, certain dyes may need binding agents to help the dye molecules bond to the material being dyed. Fixatives and binding agents can improve color fastness and overall durability of the dye.

Borax acts as a crosslinking agent in the slime-making process. When borax is added to glue, it creates a chemical reaction that links the glue molecules together, forming a slime-like consistency. This crosslinking process changes the glue's properties, transforming it into slime.
Crosslinking is the process by which adjacent chains in a polymer are joined together, forming a network of interconnected chains. This crosslinking enhances the strength and durability of the polymer by reducing flexibility and increasing resistance to breakage.

There are a number of spray fixatives available from your local art supply store. Speak with a staff member for their best suggestions.
No, baking soda cannot be used as a fixative for dyeing. A fixative is a substance used to set or bind dyes to the fabric, and baking soda does not have this property. Common fixatives for dyeing include vinegar, salt, and commercial fixatives.
Penicillin, ampicillian and the like.
