1Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… …
2Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… …
3Fold (geology) — For other uses, see Fold (disambiguation). Very tight folds. Formation near Moruya, New South Wales, Australia …
4Book embedding — In graph theory, book embedding is a generalization of planar embedding to nonplanar surfaces in the form of a book , a collection of pages (halfplanes) joined together at the spine of the book (the shared boundary of all the halfplanes). The… …
5metamorphic rock — Any of a class of rocks that result from the alteration of preexisting rocks in response to changing geological conditions, including variations in temperature, pressure, and mechanical stress. The preexisting rocks may be igneous, sedimentary,… …
6MOSFET — Two power MOSFETs in the surface mount package D2PAK. Operating as switches, each of these components can sustain a blocking voltage of 120 volts in the OFF state, and can conduct a continuous current of 30 amperes in the ON state, dissipating up …
7Cross-bedding — Crossbedding of sandstone near Mt. Carmel road, Zion Canyon, indicating wind action and sand dune formation prior to formation of rock (NPS photo by George A. Grant, 1929) …
8Microtome — A microtome used in microscopy. A microtome (from the Greek mikros, meaning small , and temnein, meaning to cut ) is a sectioning instrument that allows for the cutting of extremely thin slices of material, known as sections. Microtomes are an… …
9Dielectric elastomers — (DEs) are smart material systems which produce large strains (up to 300%[citation needed]) and belong to the group of electroactive polymers (EAP). Based on their simple working principle dielectric elastomer actuators (DEA) transform electric… …
10Organic solar cell — An organic photovoltaic cell (OPVC) is a photovoltaic cell that uses organic electronics a branch of electronics that deals with conductive organic polymers or small organic molecules[1] for light absorption and charge transport. The plastic… …
