Glassy States refer to the amorphous state of a material where it behaves like a solid but has a disordered atomic structure like a liquid. Characteristics of Glassy States: Non-crystalline: Lacks long-range order typical of crystals. Transition: Forms when a liquid is cooled rapidly, bypassing the crystalline state, resulting in a solid without a defined … Read more

It consists of four carbon atoms, six hydrogen atoms, and four oxygen atoms, and structurally, it contains two carboxyl (-COOH) groups. It occurs naturally in plants, animals, and microorganisms, and plays a role in the citric acid (Krebs) cycle as an … Read more
Liquid Crystals are substances that exhibit properties between those of conventional liquids and solid crystals. They flow like a liquid but have some degree of ordered structure. They are most well-known for their use in liquid crystal displays (LCDs). Types of Liquid Crystals: Thermotropic: Change their phase in response to temperature. Nematic Phase: Molecules are … Read more
