La Polymerisation Radicalaire par Ouverture de Cycle (R-ROP) est une methode de synthese de polymeres contenant des fonctions chimiques de choix dans le squelette carbone grâce a un mecanisme d'addition-fragmentation. L'utilisation de monomeres specifiques, les Acetals Cetenes Cycliques (CKA), permet dans certaines co…
La Polymérisation Radicalaire par Ouverture de Cycle (R-ROP) est une méthode de synthèse de polymères contenant des fonctions chimiques de choix dans le squelette carboné grâce à un mécanisme d'addition-fragmentation. L'utilisation de monomères spécifiques, les Acétals Cétènes Cycliques (CKA), permet dans certaines co…
Herein, we demonstrate that a perfect replication of a desired composition is not only related to the degree of interconnectivity of the double gyroid ordered mesoporous silica template, there is also an enormous effect from the nature of precursor and its composition. For the first time, the symmetry of ordered mesop…
Des produits de consommation de première nécessité aux produits les plus fortuits, l'emballage, en particulier plastique, constitue aujourd'hui un élément indispensable de notre vie quotidienne. Son utilisation intensive dans le domaine agroalimentaire pour un usage unique à courte durée de vie incite aujourd'hui à s'…
The present paper is devoted to the study of classes of mappings with\nnon-bounded characteristic of quasiconformality. It is obtained a result on\nnormal families of the open discrete mappings $f:D\\rightarrow {\\Bbb\nC}\\setminus\\{a, b\\}$ of the class $W_{loc}^{1, 1}$ having a finite distortion\nand omitting two f…
We study the propagation of light in a three-dimensional double-periodic\nAg/TiO2 multilayer metamaterial composed of coupled plasmonic waveguides\noperating in the visible and UV spectral range. For these frequencies, light\npropagation in the plane of the waveguides is described by a negative phase\nvelocity, while…
Industrial production of the detergent enzymes takes place in fermenters 40–125 m3 in size by Bacillus licheniformis. Without the use of specific enzymes and specially tailored enzyme mixtures, the high performance of modern detergents would be not feasible.
The production of granules from powdered solids takes place in dry conditions under pressure or with the addition of liquids with subsequent drying/cooling. These processes are well established in industry worldwide.

In chemical conversions, the raw materials and the synthesis route as well as the chemical reactor(s) with the appropriate operating conditions influence the product design. The product quality depends in particular on the removal of reaction heat and the residence time distribution.

In extraction and processing of materials from natural resources, reactions between ground raw materials and fluid media (gases, liquids) occur. In model ideas (“shrinking core”), the starting particles shrink during reaction, shown in several examples from practice.

In the past 50 years, powdery and granular detergents have improved significantly in performance and ecology. The production of solid detergents expires in spray towers either without or with a compaction step and in “non-tower” agglomeration plants. Latest generation of granulation allows the production of spherical…
Calculations predict very strong oxygen adsorption on hybrid carbon and boron-nitride nanotubes, as compared to pristine materials. In addition, oxygen binding increases the conductivity of the hybrid nanotubes, suggesting the potential to use these materials in sensor applications. On page 1058 (DOI: 10.1002/jcc.2358…
Abstract : The goal of this research project is to develop highly conductive graphene composite carbon nanofiber (CNF) webs with an electrical conductivity larger than 1000 S/cm. In addition, metal-oxide-nanostructures on the surface of CNF webs will also be developed. These highly conductive and surface-modified CNF…
Certification requirements for aviation gas turbine disks; design and technological solutions for provision of disks high reliability and life time; methods of disks confirmation compliance to requirements are considered.
Ab-initio calculations based on density functional theory (DFT) have been performed to study the optical properties of pure graphene and have been compared to that of individual boron (B), nitrogen (N) and BN co-doped graphene sheet. The effect of doping has been investigated by varying the concentrations of dopants f…
This Letter studies a weakly and asymmetrically coupled three-lane driven diffusive system. A non-monotonically changing density profile in the middle lane has been observed. When the extreme value of the density profile reaches $ρ=0.5$, a bulk induced phase transition occurs which exhibits a shock and a continuously…
14C is a radionuclide of considerable interest in nuclear power production. Its \n5730 years of half-life and a big mobility in the environment make it present in ali \nparts of nuclear reactor primary system. \nFrom there it pass to the environment through gaseous and liquid discharges \nand through the disposal of r…
