Unreferenced date December 2009 In chemistry , deposition is the settling of particles atom s or molecule s or sediment from a solution , suspension chemistry suspension and mixture or vapor onto a pre existing surface . Deposition generally results in growth of new Phase matter phase and is of fundamental importance in a large number of scientific disciplines and practical applications, the most obvious ones being in geology, meteorology and chemical engineering. The term is also widely used in earth science to describe the same process in a deposition sediment geological sense . Deposition of particles is an aggradational process &mdash one that builds a landform &mdash as opposed to a degradational process that erodes or reduces the size of a landform. For example, a river mouth river delta delta is formed by deposition of sediment carried by the stream as the river current diminishes upon encountering the sea . Deposition can be viewed as a process reverse to Sublimation chemistry sublimation , Dissolution chemistry dissolution , or particle re entrainment.

technical date September 2010 Underpotential deposition UPD is a phenomenon of electrodeposition of a chemical species species typically reduction chemistry reduction of a metal cation to a solid metal at a potential less negative than the equilibrium Nernst equation Nernst potential for the reduction of this metal. The occurrence of underpotential deposition is often interpreted as a result of a strong interaction between the electrodeposition electrodepositing metal M with the Substrate materials science substrate S of which the electrode is built . The M S interaction needs to be energetically favoured to the M M interaction in the crystal lattice of the pure metal M. This mechanism is deduced from the observation that UPD typically occurs only up to a monolayer of M sometimes up to two monolayers . The electrodeposition of a metal on a substrate of the same metal occurs at an equilibrium potential , thus defining the reference point for the underpotential deposition. Underpotential deposition is much sharper on monocrystal s than on polycrystalline materials. ref J.O M.Bockris, A.K.N.Reddy and M.Gamboa Aldeco, Modern Electrochemistry , 2nd edition, Volume 2A, Kluwer Academic Plenum Publishers, 2000. ref References reflist Category Electrochemistry chemistry stub zh ... more details

The sculpture, on which Michelangelo worked between 1547 and 1553, depicts four figures the dead body of Jesus Christ , newly taken down from the Cross, Nicodemus or possibly Joseph of Arimathea , Mary Magdalene and the Virgin Mary. The sculpture is housed in the Museo dell Opera del Duomo Florence Museo dell Opera del Duomo in Florence . Michelangelo s last sculptures were two piet s or three assuming the Palestrina Piet is his work . According to Vasari, Michelangelo made the Florence Piet to decorate his tomb in Basilica di Santa Maria Maggiore Santa Maria Maggiore in Rome . After smashing the sculpture, he gave it to his servant Antonio. Later the servant sold the work and the new owner had it reconstructed by Tiberio Calcagni following Michelangelo s models. The face of Nicodemus under the hood is considered to be a self portrait of Michelangelo himself. Additionally, the female figure at left was finished by sculptor Tiberio Calcagni. Cacagni was assigned the job after Michelangelo abandoned the sculpture after eight years of tireless work upon discovering an impurity in the marble that had gone undiscovered until that point.

Evaporation is a common method of thin film deposition . The source material is evaporation evaporated in a vacuum . The vacuum allows vapor particles to travel directly to the target object substrate , where they condense back to a solid state. Evaporation is used in microfabrication , and to make macro scale products such as metallize d plastic film. Physical principle Evaporation involves two basic processes a hot source material evaporate s and condense s on the substrate. It resembles the familiar process by which liquid water appears on the lid of a boiling pot. However, the gaseous environment and heat source see Equipment below are different. Evaporation takes place in a vacuum, i.e. vapors other than the source material are almost entirely removed before the process begins. In high vacuum with a long mean free path , evaporated particles can travel directly to the deposition target without colliding with the background gas. By contrast, in the boiling pot example, the water vapor pushes the air out of the pot before it can reach the lid. At a typical pressure ... pressure, the resulting deposition is generally non uniform and tends not to be a continuous or smooth film. Rather, the deposition will appear fuzzy .

Deposition is a Thermodynamic process process in which gas transforms into solid also known as desublimation . The reverse of deposition is sublimation chemistry sublimation . One example of deposition is the Process science process by which, in sub freezing air , water vapor changes directly to ice without first becoming a liquid . This is how snow forms in cloud s, as well as frost and hoar frost on the ground. Another example of physical deposition is the artificial process of physical vapor deposition , used to deposit thin films of various materials onto various surfaces.

In aerosol physics, Deposition is the process by which Particulate aerosol particles collect or deposit themselves on solid surfaces, decreasing the concentration of the particles in the air. It can be divided into two sub processes dry and wet deposition. The rate of deposition, or the deposition velocity , is slowest for particles of an intermediate size. Mechanisms for deposition are most effective for either very small or very large particles. Very large particles will settle out quickly through sedimentation settling or impaction processes, while Brownian diffusion has the greatest influence on small particles. ref Seinfeld and Pandis, Atmospheric Chemistry Textbook ref This is because very small particles coagulate in few hours until they achieve a diameter of 0.3 micrometers.
