Precipitation hardening is a technique that strengthens malleable materials by creating solid impurities that halt dislocation movement. Alloys such as aluminum, magnesium, nickel, and titanium are used. The process involves heating the material, quenching it, and aging it. Impurities disrupt the crystal lattice structure, increasing yield strength. Alloys produced through precipitation hardening are used in […]
Sulfate precipitation involves adding a sulfate salt to a solution to extract proteins, using either “salting” or cold saline solutions. Precipitation is the opposite of dissolution, where solids form from a solution. More reactive materials displace less reactive ones, causing the protein to solidify. Two sulfate precipitation methods are used, salting and cold ammonium sulfate […]
Ethanol precipitation is a method of DNA extraction from a saline solution. DNA is attracted to positively charged ions in salt, which allows it to easily move away from water when ethanol is added. This method is important for genetic studies. Ethanol precipitation is a DNA extraction process in which this material is extracted from […]
DNA precipitation is a crucial step in isolating and purifying genetic material. Common methods involve adding ethanol, isopropanol, or glycogen to the liquid sample, causing the DNA to solidify and fall to the bottom. A centrifuge is used to separate components, leaving a clear liquid containing genetic material. Chemicals are added to perform DNA precipitation, […]
Precipitation occurs when water vapor in the atmosphere condenses into droplets and falls to the ground as rain, snow, sleet, hail, or graupel. It is part of the planet’s water cycle and can be caused by various factors such as turbulence, mountain winds, and the lake effect. Precipitation can also have harmful effects, such as […]
Protein precipitation is a method to extract and purify proteins. Adding salt, organic solvents, or acid can reduce solubility and cause precipitation. Metal ions and nonionic hydrophilic polymers can also be used. Protein precipitation is a method used to extract and purify proteins contained in a solution. Large and complex molecules, proteins generally have parts […]
