Le travail réalisé durant cette thèse vise à offrir à un code de simulation en dynamique des dislocations les composantes essentielles pour permettre le passage à l’échelle sur les calculateurs modernes. Nous abordons plusieurs aspects de la simulation numérique avec tout d’abord des considérations algorithmiques. Pou…

Although clinically useful, passive targeting strategies suffer from several limitations. A vast majority of nanoparticles utilize a surface coating of PEG for biocompatibility; however, this hydrophilic surface hampers endosomal escape and intracellular uptake of the carriers into tumor cells creating the so-called “…
year on 26-29 July 2015 in Keystone, CO, USA (see http://www.siliconworkshop.com). Since the inception of the first workshop 1 in August 1990, the focus of the workshop has shifted from the 'Role of point defects/defect complexes in silicon device fabrication' to 'Advanced diagnostics, heterojunction solar cells and a…
We study the quantum capacitance Cq in the objects with completely discrete structure of electron states as a result of both dimensional quantization and applied magnetic field. The capacitance is analyzed in such objects as nanoplates of metal, semiconductor and semimetal. Factors which define the form of the depende…

Copolymers of ethylene (propylene) and 5-ethylidene-2-norbornene (ENB) containing 5-65 mol% of the cyclic comonomer units (ENB) in the main chain were synthesized by using homogeneous ansa-zirconocene catalysts of С 2 symmetry. They are rac-Et(Ind)2ZrCl2 (1), rac-Et(H4Ind)2ZrCl2 (2), rac-Me2Si(Ind)2ZrCl2 (3), Me2C(Ind…
Figure 1.1 Covalent (a) and noncovalent (b) functionalization of carbon nanotubes.First problem arising in modeling the noncovalent interactions is usually the choice of an appropriate method of calculation. A correct description of the p-p interaction between carbon surfaces and planar organic molecules requires the…
Electrospun nanofibrous materials are widely used in medical applications such as tissue engineering scaffolds, wound dressing material and drug delivery carriers. For tissue engineering scaffolds, the structure of the nanofiber is similar to extracellular matrix (ECM) which promotes the cell growth and proliferation.…
The solubility of components has been studied in a wide range of temperatures and compositions in the systems of copolymers of ethylene – aminoalkoxysilane. Phase diagrams have been constructed. The solubility of the components in different temperatures and concentration areas has been identified, and structure of the…
For the rational design of a microgel for the delivery of a specific drug at a specific rate in a specific physiological context, many chemical, physical, and biological parameters must be considered. In Fig. 8.1, we summarize the key design parameters that will be briefly discussed in this section.

Aspects of two new applications of photopolymerizable acrylic compositions, namely as a registering medium for optical data recording and a polymer sensor element for gas analysis, are discussed. The first application is based on the possibility of generation of surface plasmon resonance by gold nanoparticles formed i…
Removal of solids is invariably the first step in the downstream. The dead biomass, cell debris and other insoluble salts from the fermentor broth are removed by one of these techniques. Immobilized biocatalyst is also removed and recycled for reuse. If the desired product is intracellular then the cells have to be ha…
In this review, the nanobiohybrids formed by DNA/RNA and single-walled carbon nanotubes (SWNTs) have been considered focusing on the structures of the hybrids and the interaction energy between components. It discusses the influence of the polymer type, base sequence, oligomer length, polymer flexibility, and nanotube…
L’emergence du concept du developpement durable a fait que l’impact des materiaux polymeres sur l’environnement devienne une question pregnante et a conduit a se pencher sur les polymeres bio-sources et biodegradables. [1] Le present travail a pour objectif d’elaborer des materiaux polymeres fonctionnels a base de pol…
Проведено аналіз динаміки зміни концентрації радіоактивних аерозолів під час вилучення паливовміщуючих матеріалів (ПВМ) та інших радіоактивних відходів з об’єкта «Укриття» з урахуванням системи вентиляції нового безпечного конфайнменту (НБК). Показано, що в разі вилучення за зміну двох контейнерів з ПВМ об’ємом 3 м3 к…
Synthesis, structure, and thermal and mechanical properties of hybrids and blends of inorganic polymers, such as boron oxides, phosphates, sulfophosphates, and fluorophosphates with organic thermoplastics, were investigated and analyzed. The use of these hybrids presents a very promising line in the development of pol…
The problem on determination of the dynamical stress intensity factors for a crack of the shape of three-segment broken line is solved. The crack is located in an infinite elastic medium in which the longitudinal shear harmonic waves are propagated. The initial problem is reduced to a system of three singular integro-…
