Graphene nanoribbons: Graphene nanoribbons (GNRs, also called nano-graphene ribbons or nano-graphite ribbons), are strips of graphene with ultra-thin width (Silicene: Silicene is a two-dimensional allotrope of silicon, with a hexagonal honeycomb structure similar to that of graphene.Atomic absorption spectroscopy: Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.Reference electrode: A reference electrode is an electrode which has a stable and well-known electrode potential. The high stability of the electrode potential is usually reached by employing a redox system with constant (buffered or saturated) concentrations of each participants of the redox reaction.Bioelectrochemical reactor: Bioelectrochemical reactors are a type of bioreactor where bioelectrochemical processes can take place. They are used in bioelectrochemical syntheses, environmental remediation and electrochemical energy conversion.Bipolar electrochemistry: Bipolar electrochemistry is a phenomenon in electrochemistry based on the polarization of conducting objects in electric fields. Indeed, this polarization generates a potential difference between the two extremities of the substrate that is equal to the electric field value multiplied by the size of the object.Chronoamperometry: Chronoamperometry is an electrochemical technique in which the potential of the working electrode is stepped and the resulting current from faradaic processes occurring at the electrode (caused by the potential step) is monitored as a function of time. Limited information about the identity of the electrolyzed species can be obtained from the ratio of the peak oxidation current versus the peak reduction current.Chondrule: Chondrules in the chondrite Grassland|200px|thumb|Chondrules in the chondrite Grassland. A millimeter scale is shown.Supernova Early Warning System: The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in the Milky Way Galaxy, our home galaxy, or a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. Enormous numbers of neutrinos are produced in the core of a red giant star as it collapses on itself.Copper in heat exchangers: Heat exchangers are devices that transfer heat in order to achieve desired heating or cooling. An important design aspect of heat exchanger technology is the selection of appropriate materials to conduct and transfer heat fast and efficiently.Shpolskii matrix: 325px|thumb|Figure 1. Absorption spectrum of dimethyl-s-tetrazene in [[heptane|n-heptane at 4.Submillimetre astronomy: Submillimetre astronomy or submillimeter astronomy (see spelling differences) is the branch of observational astronomy that is conducted at submillimetre wavelengths (i.e.Morbidity and Mortality Weekly Report: The Morbidity and Mortality Weekly Report is a weekly epidemiological digest for the United States published by the Centers for Disease Control and Prevention (CDC). It is the main vehicle for publishing public health information and recommendations that have been received by the CDC from state health departments.Mains electricity by country: Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. Every country has differing rules regarding distribution of electricity for portable appliances and lighting.Diamond Film: The Diamond Film () is a film award recognising domestic box office achievements in the Netherlands. The Diamond Film is awarded to films from the Netherlands once they have sold 1,000,000 cinema tickets or more during the original circulation.Aluminium toxicity in dialysis patients: Aluminium toxicity is a problem for patients on haemodialysis. The dialysis process does not efficiently remove excess aluminium from the body, so it may build up over time.Liquid junction potential: Liquid junction potential occurs when two solutions of different concentrations are in contact with each other. The more concentrated solution will have a tendency to diffuse into the comparatively less concentrated one.Electrolysis: In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially highly important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.Carbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.Moonlight: [22-12-47-moonlight.jpg|thumb|A photograph taken by moonlight with an exposure time of fifty minutes.
