Salt formation provides a means of altering the physicochemical and resultant biological characteristics of a drug entity without modifying its molecular structure. Many published reviews have indicated the importance of the selection of the most appropriate salt form. This work is an investigation into the salt formation of two heterocyclic drugs. This is done by the physicochemical and the crystallographic studies of 19 high resolution single crystal diffraction studies. The particular targets of the work are the selection of the most appropriate salt forms, investigations into the tautomerism and polymorphism (or pseudopolymorphism) and an understanding of the interactions most likely between these heterocyclic drugs and their specific receptor sites. Section 1 describes the effect of protonation on the absorption of drugs, the rationale for using various salt forms and the resultant effect this has on a number of physicochemical properties of the parent compound. Section 2 is a description of the experimental techniques used in the physicochemical investigations and in crystal structure determination. In Sections 3 and 7, the preparation and characterisation of the salts and modifications of the two heterocyclic drugs, GU and IM is described. In Sections 4 and 8, the physicochemical investigations into the hygroscopicity and solid-state stabilities of the salts of GU and IM is described. Van't Hoff solubility studies are used to determine the enthalpies of solution and where appropriate the relative thermodynamic stabilities of the various phases produced. The structures of 19 of the salts or modifications of GU and IM, together with their packing and hydrogen bonding interactions is described in Sections 5 and 9. Sections 6 and 10 describe the ionisation properties of these molecules. Both the guanidine and imidazole moieties of GU and IM, respectively, are tautomeric, the particular form(s) found in these investigations and the effect of protonation is discussed. The conformations of these structures are discussed and the effect of protonation, especially on the puckering of the piperazine ring, is described.

In this work, the phase behavior of binary systems comprising nitrogen and a noble element (nitrogen + argon and nitrogen + krypton) was studied at high density in the condensed state. Following the work of Lotz et al.[2001], the main goal of this work was to further investigate the pressure-concentration phase diagram as well as to look for the possible formation of van der Waals compounds at elevated pressures and room temperature and study their physical properties, using both vibrational spectroscopy and X-ray diffraction. The observed phases, formed by single atoms and/or simple molecules in the binary systems were solved and modeled for their corresponding crystalline structures. From experimental results, lattice parameters for all crystalline structures and phase transitions, if detected, have been observed to shift with respect to that of the pure substances. The analyses and characterization of these binary systems are discussed in detail.

In the first article, the seismic properties for a suite of rocks along the West Cycladic Detachment System (Greece) are calculated, using Electron backscatter diffraction (EBSD) measurements and the minerals’ elastic stiffness tensors. Muscovite and glaucophane well defined crystallographic preferred orientation increases the seismic anisotropy. Maximum Pwave velocities have the same orientation as the Miocene extension and maximum S-wave anisotropy is subhorizontal, parallel with mineral alignment, suggesting strong radial anisotropy with a slow subvertical axis of symmetry. In the second article, teleseismic receiver functions are calculated for an array of stations in the Cyclades and decomposed into back-azimuth harmonics to visualise the variations in structure and anisotropy across the array. Synthetic receiver functions are modeled using the first order structural observations of seismic discontinuities and EBSD data. They indicate 5% of anisotropy with slow symmetry axis in the upper crust, and demonstrate the importance of rock textural constraints in seismic velocity profile interpretation.

Diffuse X-ray scattering is a rich source of local structural information over and above that obtained by conventional crystal structure determination (crystallography). The main aim in the book is to show how computer simulation of a model crystal provides a general method by which diffuse scattering of all kinds and from all types of materials can be interpreted and analysed. Part I gives a description of the experimental methods used to obtain diffuse scattering data including recent improvements both in synchrotron and neutron facilities and latest detectors that are now available. Part II describes a number of stochastic models of disorder, which allows various concepts to be established and enables simple examples to be generated to illustrate key principles. Part III describes example studies of a wide variety of real materials. These examples not only document the development of computer simulation methods for investigating and analysing disorder problems but also provide a resource for helping future researchers recognise the kinds of effects which can occur and for pointing the way to tackling new problems which are encountered. Part IV describes more recent studies in which the increased computational power, coupled with improvements in the quality and quantity of data that is now obtainable, has allowed more quantitative and detailed analyses to be undertaken.

This work presents the results of ongoing investigations aimed at determining the influence of crystallographic texture, microtexture and mesotexture on hydrogen induced cracking (HIC) in low carbon pipeline steels. HIC samples of two steels were investigated using X-ray diffraction texture measurement and Orientation Imaging Microscopy (OIM™). The first steel is a low strength API 5L X46 retired from service and the second is a low sulfur ASTM A106 steel. The results of this work confirm the feasibility of improving the HIC resistance of pipeline steels through crystallographic texture control and grain boundary engineering. Controlled rolling schedules can be proposed in order to induce a crystallographic texture dominated by the {112}//ND, {111}//ND and {011}//ND fibres. Such a texture is expected to decrease significantly the steel susceptibility to HIC by: (i) reducing the number of available transgranular and intergranular low resistance cleavage paths provided by the {001}//ND oriented grains, (ii) reducing the probability of crack coalescence and stepwise HIC propagation and (iii) increasing the number of high resistance intergranular crack paths provided by coincidence site lattice (CSL) and low angle boundaries with the lowest possible energy.

Spatial solitons in photorefractive media have been the subject of intense theoretical and experimental investigations [1]. One of the first experimental demonstrations of self-focusing and self-defocusing effects has been done in cubic barium titanium oxide (BTO) crystal [2], where the so called screening solitons [3] have been observed. The cubic crystals are attractive because for some crystallographic orientation, the optical beam either experiences self-focusing or self-defocusing, depending on polarization. Thus, for fixed direction of the biasing electric field, bright, dark or coupled bright and dark solitary beams are possible. However, some cubic crystals exhibit strong natural optical activity (OA) which is 6.3°/mm for BTO. Since the photorefractive nonlinearity strongly depends on polarization, polarization rotation may destroy the soliton propagation. In the present work, we examine the influence of optical activity on propagation of screening solitons in cubic PR crystal.

Fatigue life of polycrystalline materials is mainly governed by the early stages of surface short cracks. Initiation and micro-propagation phases, which represent from 50% to 80% of total component life, are experimentally proven to depend on material microstructure. The aim of this numerical study is to highlight the influence of local parameters (e.g. crystallographic orientation) on the short crack initiation. Finite element computations are performed with a crystal plasticity model. The investigations are carried out on 316L Stainless Steel with different fatigue loadings and various surface roughnesses. A qualitative study of volumetric strain localization is carried out to distinguish uniaxial and biaxial results. The slip plane activity in surface grains is characterized. Many configurations are tested to provide a statistical point of view. Results revealed the strong vulnerability of surface grains with a high Schmid factor on systems that produce extrusions. It is also demonstrated that taking account of geometrical singularities can strongly change the plastic strain localization due to crystal orientation.

Abstract Titanium suboxides form a class of ceramic materials possessing such technically interesting properties as electrical conductivity and solid lubrication. Consequently, these materials have a high potential for application as thermally sprayed coatings. In this paper the preparation and characterisation of two spray powders of different composition by agglomeration and sintering with a narrow range of the value n in TinO2n-1 is described. Powders were characterised by X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM), thermogravimetric measurements (TG), helium pycnometry, nitrogen adsorption and mercury intrusion techniques. The sprayability was tested by plasma spraying. The coating structures were studied by optical microscopy, XRD, TG and TEM. Although the powders were only partially oxidized as a result of the spray process, the crystallographic structure was changed significantly, according to XRD and TEM investigations. As an alternative method of preparation of titanium suboxide spray powders, the reduction of a fused and crushed spray powder with hydrogen is described. Powder particle shape and size distribution are not changed in this process.

The overall objective of this study was to evaluate whether surface crystal orientation can be used to associate metal fracture fragments. This study examined the orientations of the fractured crystals across the fracture plane for two surfaces determined to be a matching fracture by conventional methods. This study used Electron Back-Scattered Diffraction (EBSD), sometimes known as Orientation Imaging Microscopy (OIM), to determine the crystallographic orientation of individual metal crystals along the length of the fracture on a surface perpendicular to the actual fracture surface. This investigation examined the uniqueness of crystal orientations within a metal and examined the requirements necessary for determination of crystallography using EBSD. This study also examined the crystallographic information as to whether it is sufficiently reliable characteristic from which a quantitative determination could be made that two separate pieces of metal are, in fact, from a single piece.

The plasma protein inhibitor anti thrombin III in its native form has been crystallized using standard techniques.The crystals diffract to about and belong to space group P41212 with cell parameters:a = b = 90.6<, c = 380.7<.The asymmetric unit contains three molecules of anti thrombin III.The self rotation function computed with the native data set indicates the presence of a non crystallographic three fold axis. Cross rotation function calculations using themodel of the cleaved α1,-antitrypsin (H. Loebermann at.,J. Mol. Biol.(1985) 177, 531) suggests tertiary structuresimilarities between the two plasma proteins.This is in agreement with the already described primary sequence homology of these glycoproteins but at variance with the model of active α1-anti trypsin inferred from the previous studies on the cleaved molecule.The technical assistance of M. Maman is deeply appreciated.
