Ionic liquidAn ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below a specific temperature, such as . While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions. These substances are variously called liquid electrolytes, ionic melts, ionic fluids, fused salts, liquid salts, or ionic glasses. Ionic liquids have many potential applications.
Smooth morphismIn algebraic geometry, a morphism between schemes is said to be smooth if (i) it is locally of finite presentation (ii) it is flat, and (iii) for every geometric point the fiber is regular. (iii) means that each geometric fiber of f is a nonsingular variety (if it is separated). Thus, intuitively speaking, a smooth morphism gives a flat family of nonsingular varieties. If S is the spectrum of an algebraically closed field and f is of finite type, then one recovers the definition of a nonsingular variety.
Superhero filmA superhero film is a film that focuses on superheroes and their actions. Superheroes are individuals who possess superhuman abilities and are dedicated to protecting the public. These films typically feature action, adventure, fantasy, or science fiction elements. The first film about a particular character often focuses on the hero's origin story. It also frequently introduces the hero's nemesis. (See also: supervillain or archnemesis.) Many superhero films are based on superhero comics.
Comedy filmA comedy film is a category of film which emphasizes on humor. These films are designed to make the audience laugh in amusement. Films in this style traditionally have a happy ending (dark comedy being an exception to this rule). Comedy is one of the oldest genres in the film and it is derived from classical comedy in theatre. Some of the earliest silent films were comedies such as slapstick comedy which often relies on visual depictions, such as sight gags and pratfalls, so they can be enjoyed without requiring sound.
