Von einem Polymer, Nitinol und poröser Keramik: Erfahrungen mit 18 Jahren Patentanmeldungen
Auf eine längere Patenthistorie kann Matthias Epple zurückblicken. Schon als Habilitand meldete er sein erstes Patent an. In diesem Beitrag berichtet er über 18 Jahre unterschiedlichste Bedingungen und Konstellationen für Patentanmeldungen.
셀룰로오스, 카복시메틸셀룰로오스 복합체로 부터 하이드로겔 제조 및 그들의 물리적 특성 연구
NaOH/urea/증류수로 이루어진 용매를 이용하여 CMC와 셀룰로오스로부터 하이드로겔을 제조하였다. ECH(Epichlorohydrin)를 가교제로 선정하였으며, 셀룰로오스, CMC의 단일 물질로만 이루어진 하이드로겔과 두 물질의 비율을 다르게 구성한 하이드로겔들을 제조하였다. 그들의 구성비율은 Cellulose:CMC=8:2, Cellulose:CMC...

Impact of Core Dielectric Properties on the Localized Surface Plasmonic Spectra of Gold-Coated Magnetic Core–Shell Nanoparticles B
Gold-coated iron oxide core–shell nanoparticles (IO-Au NPs) are of interest for use in numerous biomedical applications because of their unique combined magnetic–plasmonic properties. Although the effects of the core-dielectric constant on the localized surface plasmon resonance (LSPR) peak position of Au-shell partic…
Aqueous foams and aerated oil-in-water emulsions partly stabilised by edible particles
The objectives of this thesis are to enhance the understanding of edible solid particle behaviour at oil-water and at air-water interfaces, and how their adsorption at these interfaces affects the emulsion and foam stability. Materials stabilised solely by solid particles are of great interest due to long-term stabili…
Interactions of Small Dendrimers with Sodium Dodecyl Sulfate at the Air–Water Interface B
We have determined how the bulk behavior of mixtures of small cationic poly(amidoamine) dendrimers (generation 2, PAMAM-G2) and sodium dodecyl sulfate (SDS) affects the structure and composition of the adsorbed layers at the air–water interface. The aim is to reveal how the size of a well-defined hyperbranched polyele…
Length Scales and Structural Dynamics in Nematogen Pseudonematic Domains Measured with 2D IR Vibrational Echoes and Optical Kerr Effect Experiments B
Nematogen liquids in the isotropic phase are macroscopically homogeneous but on multinanometer length scales have pseudonematic domains with correlation lengths that grow as the isotropic to nematic phase transition temperature (TNI) is approached from above. Orientational relaxation of nematogens in the isotropic pha…
О НАУЧНЫХ НАПРАВЛЕНИЯХ ДЕЯТЕЛЬНОСТИ НЦ «ИЗНОСОСТОЙКОСТЬ»
The key areas of research of Wear Resistance Research Center of National Research Institute “Moscow Power Engineering Institute” are outlined, the developed technologies are specified, photographs are presented of the main production and experimental equipment created in recent years in various areas.
Assessment of the Properties about the Thermal Sprayed Coatings for the Thermalbarrier Apllied to the Head of Piston of Internal-Combustion Engine
Properties of three thermal sprayed coatings were compared to select the effective sprayed coating for giving the thermal barrier to the Al alloy components of internal combustion engines. Results for coating 1 (top coat, Al2O3; bond coat, Ni-Cr), coating 2 (top coat, YSZ; bond coat, CoNiCrAlY), and coating 3 (SUS316)…
Pratique de la modélisation des processus de coupe avec assistance
L'avancement des connaissances concernant le domaine de l'usinage est principalement lie avec la comprehension de la physique des processus au sein de la zone de coupe. Afin d'aider a cet apport de connaissances, des modeles theoriques ont ete elabores car la zone petite et confinee du contact entre l'outil de coupe e…
Effect of Localized Surface-Plasmon Mode on Exciton Transport and Radiation Emission in Carbon Nanotubes B
We report on a general theoretical approach to study exciton transport and emission in a single-walled carbon nanotube (SWNT) in the presence of a localized surface-plasmon (SP) mode within a metal nanoparticle interacting via near-field coupling. We derive a set of quantum mechanical equations of motion and approxima…
Synthese und Charakterisierung neuartiger Silicium-, Germanium- und zinnorganischer Riechstoffe
Aufbauend auf dem Konzept der C/Si-Bioisosterie beschreibt die vorliegende Arbeit die Synthese und Charakterisierung siliciumhaltiger Derivate der Riechstoffe Galaxolide, Lilial, Bourgeonal, 5,7,7-Trimethyl-4-methylenoctanal und α-Galbanone sowie Beitrage zur Synthese eines silicium¬haltigen Derivats von δ-Damascone.…
Improvement of Rubber Processing by Lubricants
We here introduce very recently developed lubricants for low-temperature mixability with rubber, which are the novel combinations of selected fatty acid derivatives. Of marketed synthetic rubbers, EPR has been mixed with other necessary ingredients particularly under such a condition. In this article, therefore, the e…
Verschleißpartikel-Analyse mit Rasterelektronenmikroskopie und energiedispersiver Röntgenspektrometrie im Transmissionsmodus (TSEM/EDX)
Untersucht wurden Verschleispartikel als elektronen-transparente Proben auf dunnen Tragerfolien mit einem hochauflosendem Rasterelektronenmikroskop und energiedispersiver Rontgenspektrometrie im Transmissionsmodus. Die hohe laterale Auflosung dieser modernen Methoden ermoglicht eine morphologische Charakterisierung de…

Se esper…
Viscosity of Nafion Oligomers as a Function of Hydration and Counterion Type: A Molecular Dynamics Study B
The design of fuel cells and lithium ion batteries is constrained, in part, by mechanical creep and perforation of the polymer electrolyte, a process that is poorly understood at the molecular level. The mechanical stiffness (quantified as shear viscosity) and structure of a widely used polymer electrolyte, Nafion, ar…
El Eurocódigo 2 y la evaluación de las estructuras de hormigón con armaduras corroídas
La corrosion de la armadura es uno de los problemas de mayor impacto economico en el ciclo de vida de las estructuras de hormigon por lo que es necesario optimizar las estrategias de reparacion de estructuras corroidas. Sin embargo, a nivel internacional no hay codigos que permitan una evaluacion por lo que se incluir…
