N?o houve, no entanto, precau??es quanto ao uso dos recursos naturais utilizados como fonte de mat?ria prima para a Ind?stria. Desta maneira investigou-se a respeito de ind?cios de altera??es micrometeorol?gicas associadas ? Ind?stria de Cer?mica Estrutural nos elementos meteorol?gicos em algumas ?reas do Nordeste do Brasil. Para verificar se as vari?veis micrometeorol?gicas: precipita??o, evapotranspira??o, radia??o, velocidade do vento, umidade, e temperatura m?xima e m?nima, referentes ao per?odo de 1980 a 2013, apresentavam tend?ncias, utilizou-se o Teste de Mann Kendall; e para calcular os ?ndices de extremos clim?ticos utilizou-se o conjunto de dados para ?ndices de Extremos Clim?ticos - RClimDex. Foram identificados cinco polos, nos quais verificouse haver tend?ncias negativas para precipita??o, temperatura m?nima, umidade relativa e vento. E tend?ncias positivas para as vari?veis temperatura m?xima, evapotranspira??o e radia??o solar. Detectou-se tend?ncia em todos os polos, com exce??o da temperatura m?nima para o polo P2 (que apresenta maior n?mero de cer?micas). Identificou-se, ainda, tend?ncia para os ?ndices de extremos clim?ticos de Rx1day, R99p, Txn, Tnx, Tn10p, Tx10p, Txx e Tnn. Com tend?ncias positivas de extremos de temperatura para os polos estudados, com exce??o do polo P1 que obteve tend?ncia decrescente, indicando diminui??o dos valores m?ximos da m?nima; e do polo P2 que n?o apresentou tend?ncia para a temperatura m?nima e para os ?ndices de Tnn e Tnx e RX5day. Comportamentos adversos podem estar associados a a??es antr?picas da regi?o, especificamente ? intensa atividade ceramista. Por?m, n?o se pode afirmar categoricamente, que esse comportamento est? associado somente as a??es antr?picas, visto que pode estar sob influ?ncia de diversos agentes do clima. / In recent years the Industrial sector of red ceramic has developed representatively with the implantation of micro and small Ceramics companies throughout Brazil. There were, however, no precautions regarding the use of the natural resources used as raw material source for the Industry. In this way, we investigated the indications of micrometeorological alterations associated with the Structural Ceramics Industry in the meteorological elements in some areas of the Northeast of Brazil. In order to verify if the micrometeorological variables: precipitation, evapotranspiration, radiation, wind speed, humidity, and maximum and minimum temperature, referring to the period from 1980 to 2013, presented tendencies, the Mann Kendall test was used; And to calculate the indexes of climatic extremes the Data Set for Indexes of Climatic Extremes - RClimDex was used. Five poles were identified, in which there were negative trends for precipitation, minimum temperature, relative humidity and wind. And positive trends for the variables maximum temperature, evapotranspiration and solar radiation. A tendency was detected at all poles, with the exception of the minimum temperature for the P2 pole (which has the highest number of ceramics). A trend was also identified for the indexes of climatic extremes of Rx1day, R99p, Txn, Tnx, Tn10p, Tx10p, Txx and Tnn. With positive trends of temperature extremes for the studied poles, with the exception of the pole P1 that obtained a decreasing tendency, indicating decrease of the maximum values of the minimum; And the P2 pole which showed no tendency towards the minimum temperature and for the Tnn and Tnx and RX5day indices. Adverse behaviors may be associated with anthropogenic actions in the region, specifically intense ceramist activity. However, it can not be said categorically that this behavior is associated only with anthropic actions, since it may be under the influence of several agents of the climate.

The work presented in this dissertation focuses on the study of post deposition spatial and temporal evolution of adatom islands and molecules on surfaces using ab initio and semiemperical methods. It is a microscopic study of the phenomena of diffusion and reaction on nanostructured surfaces for which we have developed appropriate computational tools, as well as implemented others that are available. To map out the potential energy surface on which the adatom islands and molecules move, we have carried out ab initio electronic structure calculations based on density functional theory (DFT) for selected systems. For others, we have relied on semiempirical interatomic potentials derived from the embedded atom method. To calculate the activation energy barriers, we have employed the "drag" method in most cases and verified its reliability by employing the more accurate nudged elastic band method for selected systems. Temporal and spatial evolution of the systems of interest have been calculated using the kinetic Monte Carlo (KMC), or the more accurate (complete) Self Learning kinetic Monte Carlo (SLKMC) method in the majority of cases, and ab initio molecular dynamics simulations in others. We have significantly enhanced the range of applicability of the SLKMC method by introducing a new pattern recognition scheme which by allowing occupancy of the "fcc" and "hcp" sites (and inclusion of "top" site in the pattern recognition as well) is capable of simulating the morphological evolution of iii three dimensional adatom islands, a feature not feasible via the earlier - proposed SLKMC method. Using SLKMC (which allows only fcc site occupancy on fcc(111) surface), our results of the coarsening of Ag islands on the Ag(111) surface show that during early stages, coarsening proceeds as a sequence of selected island sizes, creating peaks and valleys in the island-size distribution. This island size selectivity is independent of initial conditions and results from the formation of kinetically stable islands for certain sizes as dictated by the relative energetics of edge atom detachment/attachment processes together with the large activation barrier for kink detachment. On applying the new method, SLKMC-II, to examine the self diffusion of small adatom islands (1-10 atoms) of Cu on Cu(111), Ag on Ag(111) and Ni on Ni(111), we find that for the case of Cu and Ni islands, diffusion is dominated by concerted processes (motion of island as a whole), whereas in the case of Ag, islands of size 2-9 atoms diffuse through concerted motion whereas the 10-atom island diffuses through single atom processes. Effective energy barriers for the self diffusion of these small Cu islands is 0.045 eV/atom, for Ni it is 0.060 eV/atom and for Ag it is 0.049 eV/atom, increasing almost linearly with island size. Application of DFT based techniques have allowed us to address a few issues stemming from experimental observations on the effect of adsorbates such as CO on the structure iv and stability of bimetallic systems (nanoparticles and surfaces). Total energy calculations of Ni-Au nanoparticles show Ni atoms to prefer to be in the interior of the nanoparticle. CO molecules, however, prefer to bind to a Ni atom if present on the surface. Using ab initio molecular dynamics simulations, we confirm that the presence of CO molecule induces diffusion of Ni atom from the core of the Ni-Au nanoparticle to its surface, making the nanoparticle more reactive. These results which help explain a set of experimental data are rationalized through charge transfer analysis. Similar to the case of Ni-Au system, it is found that methoxy (CH3O) may also induce diffusion of inner atoms to the surface on bimetallic Au-Pt systems. Our total energy DFT calculations show that it is more favorable for methoxy to bind to a Pt atom in the top Au layer than to a Au atom in Au-Pt system thereby explaining experimental observations. To understand questions related to the dependence of product selectivity on ambient pressure for ammonia decomposition on RuO2(110), we have carried out an extensive calculation of the reaction pathways and energy barriers for a large number of intermediate products. On combining the reaction energetics from DFT, with KMC simulations, we show that under UHV conditions, selectivity switches from N2 ( ∼ 100 % selectivity) at T = 373K to NO at T = 630K, whereas under ambient conditions, N2 is still the dominant product but maximum selectivity is only 60%. An analysis based on thermodynamics alone shows a contradiction between experimental data at UHV with those under ambient pressure. Our calculations of the reaction rates which are essential for KMC simulations removes this apv parent inconsistency and stresses the need to incorporate kinetics of processes in order to extract information on reaction selectivity.
