At present polymer and their composites is one of the largest tonnage materials. But they become a headache day after day because of depletion of petroleum and pollution of environment. Biopolymer and their composites (like Polylacticacid (PLA) and its composites) can be a suitable competitor to replace convention pol…
硅石 nanococoons 与卷或在墙中的同心圆形的毛孔隧道最近吸引了许多注意。然而，他们的形成很好没被说明。此处，空硅石与组织毛孔隧道平行轰炸到壳表面用 chiral low-molecular-weight amphiphile 的 self-assemblies 通过一个单个模板的方法被准备， L-18Phe6PyBr，在 dilute 集中下面的模板。这些 nanococoons 用 X 光检查衍射计和 N2 吸着被描绘。他们的形成清楚地在在低电压被拿的地排放电子显微镜学图象被显示出。而且，像的传播电子显微镜学图象不同反应时间显示了合作自我装配的机制。nanocoons 从卷的 nanoribbons 被形成，这也被发现。

In this work we use the topology and morphology analysis of digital images and report the use of dynamic scaling theory, fractal analysis and power spectral density in a study of the growth stages of polyaniline/poly(vinyl sulfonic acid) polymer thin films - PANI/PVS. The films were deposited on glass substrate by sel…
The purpose of this project was to develop a laboratory experiment to be conducted by future Nuclear Engineering Track (NET) students that adequately demonstrates adsorption of the lanthanide neodymium, an extraction technique used in nuclear fuel reprocessing. Nuclear fuel reprocessing is the chemical separation of v…
This article presents the findings of quantum-chemical computation for one of non-radical mechanisms of gas-phase monomolecular thermal decomposition of: cis-nitropropenes and transnitropropenes, 2-nitropropene-1 and 2-methyl-1-nitropropene. This mechanism is nitro-nitrite rearrangement. The study of this mechanism ha…
A utilização do ANFO (amonium nitrate fuel oil) implica num reduzido custo de desmonte. Entretanto, tais custos podem ser ainda mais baixos ao se substituir o óleo diesel por combustíveis alternativos como biomassa (biodiesel, palha de arroz, sabugo de milho, bagaço de cana-de-açúcar) e resíduo de pneu. Este artigo in…
The comprehensive approach to the process of training of students was developed at the Chair of Pharmaceutical Chemistry of Pyatigorsk State Pharmaceutical Academy. The solution of this problem was found by the integration of natural-science, general-professional and special disciplines. The complexity of special disc…
Development of a multidisciplinary design optimization (MDO) of a large scale hybrid composite wind turbine blade is performed. Multiple objectives are considered in the MDO process to maximize annual energy production and lifetime profit, minimize weight and power production rate. A wind turbine blade is divided into…
Availability of raw material eichornia crassipesfiber in Indonesiais relatively abundant, the potential of eichornia crassipes is very suitable for reinforcement of the materials. The particles of coconut coir (coco sponge), i.e. particles that cling to the coconu tfiber until now considered as waste material has been…
A comparison of Solvent and Dispersion methods for the extraction of Polyhydroxyalkanoates (PHA) was undertaken. No significant quantitative difference between the two methods was recorded.
This paper presents design and computational investigation of a double gate bilayer graphene field effect transistor (GFET) based on the self consistent solution of the Poisson, continuity and energy balance equations (PADRE). The investigation considers the quantum transport at the nanoscale dimension. A set of perfo…

The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is impor…
The optical properties of GaN nanocolumn structures containing InGaN quantum disks are investigated by optical microphotoluminescence spectroscopy using pulsed lasers, and cathodo- luminescence. The results are analyzed in the context of current theories regarding an inho- mogeneous strain distribution in the disk whi…
This paper investigates the possibility of cellulose paper for actuators sensors and field effect transistors. Fabrication of cellulose Electro‑Active Paper（EAPap）in terms of stretching regenerating and washing processes and its application possibility in robust biomimetic actuator strain sensor temperature and humidity…
Within a method of small parametre the field of stresses of heavy tubing cylindrical pipes is investigated at modelling of a material by the incompressible elastic-is viscous-plastic environment. The estimation of influence on size of a plastic zone physicomechanical design parametres is given.
The paper presents the results of experimental investigation of the influence of the external electrostatic field on the mass burning rate of tridekane, PMMA, SKN-26, SKMS-30, localized in the zone of gas phase reactions and c-phase. The influence of the field on the gas phase results in changing the form of the flame…
Bismuth layer-structured ferroelectrics are commercially attractive for applications such as non-volatile random access memory and high temperature piezoelectric devices due to their excellent fatigue endurance, fast switching speed, good polarization retention and high Curie temperature. BaBi4Ti4O15 is a four layered…
