  2. Photoelectrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Photoelectrochemical_cell

    A " photoelectrochemical cell " is one of two distinct classes of device. The first produces electrical energy similarly to a dye-sensitized photovoltaic cell, which meets the standard definition of a photovoltaic cell. The second is a photoelectrolytic cell, that is, a device which uses light incident on a photosensitizer, semiconductor, or ...

  3. Photoinitiator - Wikipedia

    en.wikipedia.org/wiki/Photoinitiator

    In chemistry, a photoinitiator is a molecule that creates reactive species ( free radicals, cations or anions) when exposed to radiation ( UV or visible ). Synthetic photoinitiators are key components in photopolymers (for example, photo-curable coatings, adhesives and dental restoratives). Some small molecules in the atmosphere can also act as ...

  4. Outline of chemistry - Wikipedia

    en.wikipedia.org/wiki/Outline_of_chemistry

    Physical chemistry involves the use of infinitesimal calculus in deriving equations. It is usually associated with quantum chemistry and theoretical chemistry. Physical chemistry is a distinct discipline from chemical physics, but again, there is very strong overlap. Chemical kinetics – study of rates of chemical processes.

  5. Coupon - Wikipedia

    en.wikipedia.org/wiki/Coupon

    Coupon. In marketing, a coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product . Customarily, coupons are issued by manufacturers of consumer packaged goods [1] or by retailers, to be used in retail stores as a part of sales promotions. They are often widely distributed through mail ...

  6. Molecular descriptor - Wikipedia

    en.wikipedia.org/wiki/Molecular_descriptor

    Molecular descriptors play a fundamental role in chemistry, pharmaceutical sciences, environmental protection policy, and health researches, as well as in quality control, being the way molecules, thought of as real bodies, are transformed into numbers, allowing some mathematical treatment of the chemical information contained in the molecule.

  7. Ball-and-stick model - Wikipedia

    en.wikipedia.org/wiki/Ball-and-stick_model

    In chemistry, the ball-and-stick model is a molecular model of a chemical substance which displays both the three-dimensional position of the atoms and the bonds between them. [1] The atoms are typically represented by spheres, connected by rods which represent the bonds. Double and triple bonds are usually represented by two or three curved ...

  8. Computational chemistry - Wikipedia

    en.wikipedia.org/wiki/Computational_chemistry

    Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules , groups of molecules, and solids. [3]

  9. Photographic processing - Wikipedia

    en.wikipedia.org/wiki/Photographic_processing

    For the photo editing software, see Adobe Lightroom. Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and ...
