Theory and experimental methods. Since the combined experimental-theoretical approach is stressed, both the underlying theoretical and experimental aspects receive considerable attention in chapters 2 and 3. Computational methods are presented in order to introduce the nomenclature, discuss the input into the models, and the other approximations used. Thereafter, a brief survey of possible surface science experimental techniques is provided, with a critical view towards the application of these techniques to studies of conjugated polymer surfaces and interfaces. Next, some of the relevant details of the most common, and singly most useful, measurement employed in the studies of polymer surfaces and interfaces, photoelectron spectroscopy, are pointed out, to provide the reader with a familiarity of certain concepts used in data interpretation in the Examples chapter (chapter 7). Finally, the use of the output of the computational modelling in interpreting experimental electronic and chemical structural data, the combined experimental-theoretical approach, is illustrated.

An entire book in itself would be necessary to fully explore the many different surface science experimentation techniques used within the research community, thus making this section merely a brief overview. The reader is encouraged to read the referenced literature for more in-depth information on the techniques and apparatuses used for particular measurements or investigations [17, 21-23].

Our research in the field described in this chapter was supported by grants from several foundations (DFG, BMBF, DLR, A. von Humboldt Foundation, RFBR, RAS, BRHE program - CRDF, USA, and Russian Ministry of Education and Science). Experimental results were obtained in collaboration with Dr. H. Sowa, Dr. H. Ahsbahs, Dr. H. Uchtmann, Dr. S.V. Goryainov, Prof Yu.V. Seryotkin, Dr. S.N. Ivashevskaya, Prof V.V. Chernyshev, Dr. E.B.

Volume 19 is devoted to considering simple processes occurring at the gas-solid interface. Chapter 1 serves as an introduction and deals with the methodology of experimental surface science. Experimental results for metal surfaces on both adsorption and desorption kinetics and surface diffusion are discussed in terms of the current theories of these processes. Chapter 2 deals in the same way with these processes on semi-conductor surfaces. Finally, Chapter 3 is concerned with radiation and photoeffects at gas—solid interfaces. 

Mutual Understanding. If we are to successfully encourage wood scientists to research areas that have application to conservation problems, scientists must be able to understand, if not appreciate, what constitutes both conservation problems and conservation solutions. On the other hand, if they are to become familiar with wood science literature and to apply wood science experimental results to conservation problems, conservators must be able to understand and appreciate the variability of wood, the results of degradation processes, and how these conditions affect the types of questions that can be answered, as well as the types of answers that the wood sciences can supply to conservation questions.

The fact that many scientists. .. spend most of their time doing experiments of various kinds is not reflected in the basic literature in the philosophy of science.. .. Thus, the philosophy of experimentation is still underdeveloped. .. There has been a strong tendency to take the production of empirical knowledge for granted.. .. In sum, if philosophers keep neglecting the technological dimension of science, experimentation will continue to be seen as a mere data provider for the evaluation of theories. 

Sections 5.2 to 5.7 deal primarily with obtaining data for solid phases. Section 5.8 deals with liquids, gases and solutes. An overview of many methods used by Earth science experimenters can be found in Ulmer and Barnes (1987).

The second component of onr project is the incorporation of nanoscale science experimentation into the introdnctoiy level cnrricula in each science discipline. In doing so, we emphasize topics of cnrrent research interest in nanoscale science and use a common instrament across traditional disciplines. We incorporate a modular approach to facilitate replacement of existing laboratory exercises rather than the replacement of an entire course, or the development of an additional conrse that might be poorly populated as an elective course in a number of majors. Each module is designed aroimd the use of a scanning probe microscope (SPM), operated as either a scanning tuimeling microscope (STM) or as an atomic force microscope (AFM), independent of the scientific discipline involved. We incorporate the SPM because it is commonly used in nanoscale science experiments and because one way to illustrate the field s interdisciplinary nature is to demonstrate the multiple ways one instmment can be used in several traditional fields to obtain results of interest to that field. Thus each module makes use of a SPM and a model for a SPM to instmct the students in a specific science discipline, and simultaneously in the fundamental concepts of nanoscale science. The modules themselves can be found online (15) and will be addressed more completely elsewhere.

In the historical development of science, experimental progress in the accuracy of measurements have often brought about a refinement of theoretical models or even the introduction of new concepts [14.1]. Examples are A. Einstein s theory of special relativity based on the interferometric experiments of Michel son and Morley [14.2] M. Planck s introduction of quantum physics for the correct explanation of the measured spectral distribution of black-body radiation, the introduction of the concept of electron spin after the spectroscopic discovery of the fine structure in atomic spectra [14.3] or the test of quantum-electrodynamics by precision measurements of the Lamb shift [14.4]. 

Residual tests were carried out in maize fields at Agricultural Science Experimental Station of Jilin Agricultural University in 2005 and Hailun city in Heilongjiang in 2006. The residual tests were performed by College of Resource and Environmental Science, Jilin Agricultural University. During the growth season, maize was sprayed one time with 30 % clacyfos EC at 900 g ai/ha. 

Reasonable fits could be obtained (within 10% of experimental values) if activated dissociation of nitrogen was invoked as, found by Scholten et al. [85] on singly promoted catalysts. The authors point out, however, that there is no surface science experimental evidence for activated nitrogen dissociation on potassium promoted iron. 

In fundamental reactor science, experimental studies display several essential concepts from neutron and reactor physics. Total neutron cross section is measured by a method involving basic neutron-beam techniques in other exercises, measurements of isotopic neutron cross sections and absolute neutron fluxes are made by use of activation methods in the thermal, resonance, and fast regions of the neutron spectrum. The resonance escape probability and fast fission factor are evaluated in the lattice of the Argonaut reactor.
