Исследование влияния состава глинистых горных пород и степени их увлажнения на устойчивость стенок скважины. Joshi, Encyclopedia of the Human Genome, Nature Publishing Group, vol 5, 606-613 2003. Can shale swelling be easily controlled? Of special interest are chemical reactions which occur at the expense of thermodynamic stabilization of the forming chemical species in a new supramolecular environment. However, the stiffness of the mixed gels was much higher than the sum of the corresponding individual gels. The switching off the sorbent functionality was performed by the application of a temperature pulse 3 ; the disappearance of the microporosity was observed due to collapse of the metastable β-form back into the stable α form.

Among the topics discussed are the nature of intermolecular interactions and their role in crystal design, the sometimes diverging perceptions of the geometrical and chemical models for a molecular crystal, the relationship of these models to polymorphism, knowledge-based computational prediction of crystal structures, and efforts at mapping the pathway of the crystallization reaction.

We are currently investigating the effects of capillary interactions on the microstructure of ellipsoid stabilized interfaces, and the effects of this microstructure on nonlinear rheological behavior. The purpose of this Review is to highlight some current challenges in this rapidly evolving subject. Тест на диспергирование обеспечивает получение информации о диспергирующих свойствах раствора при попадании в раствор бурового шлама при разбуривании глинистых горных пород.

Работа представлена на 158 страницах машинописного теста, содержит 69 рисунков и 11 таблиц. Существующие типы тестов для описания глин разделяется на описательные, статические и динамические и представлены в табл. Исходя из состава и свойств глинистых отложений разработать их классификацию для выбора эффективных составов и свойств буровых растворов. Systems with particle-stabilized interfaces, such a Pickering emulsions or foams, tend to have superior stability compared to emulsions and foams stabilized by simple surfactants, and with our work we wish to obtain a deeper understanding about the structure-property relations of these systems.

A major factor that governs the primary synthon formation is the basic character of the proton acceptors in the heterocyclic compounds. Importantly, cocrystal cohesive energies are more favourable than that of the respective single component crystal structures, which supports the cocrystal formation when both coformers are dissolved and mixed together. © 2004 Kluwer Academic Publishers. Минералогия и практическое использование глин Текст.

Recently special efforts have been applied to create sorbents which respond to the sorption process with slight structural modifications in the host matrix. Crystal engineering has considerable overlap with supramolecular chemistry, X-ray crystallography, materials science, and solid-state chemistry and yet it is a distinct discipline in itself. We explain this result in terms of an adjusted random contact model for charged semiflexible fibrils. Currently it is a major, interdisciplinary branch of science dealing with chemical, physical, biological and technological aspects of the creation and study of complex chemical systems based upon non-valent interactions.
