Grain boundaries (GBs) in single layer graphene are extended lattice defects that form at the interface between graphene grains. These defects are common in graphene grown by chemical vapor deposition. In this thesis, I study periodic models of twin grain boundaries, which form when adjacent domains are rotated by an…
На основе поливинилового спирта получили карбонизованные волокна в виде комплексной технической нити с разрывной прочностью выше 200 МПа и удельной электропроводностью не менее 0,5 См/см. С помощью термогравиметрического и дифференциально-термического анализа, методов Рамановского рассеяния и рентгеновской дифракции в…
We have ever applied PFT-ELS (Equivalent linear system using the restoring force model of power function type) method to analyze the nonlinear vibration characteristic of seismic isolation laminated rubber. However, the restoring force characteristics cannot express shapes like experimental values in the PFT-ELS metho…
Neste trabalho foram investigados processos de otimização para integração de suportes metálicos porosos selecionados (mono e multicamada) para desenvolvimento de células a combustível de filme fino (TF-SOFC) via deposição de laser pulsado (PLD). A rugosidade superfícial micrométrica dos suportes metálicos porosos é um…
This Ph.D. thesis deals with the exploitation of lignocellulosic industrial biowastes as potential reinforcing agents and flame retardants in sustainable polymer matrices, with the aim of obtaining bio-composites with improved properties and reduced production costs. The work is based on two main activities, the first…
Metals and alloys with low stacking fault energy (SFE) undergo twinning within their grains. Twinning Induced Plasticity (TWIP) steels possess an exceptional combination of tensile strength and ductility, and therefore, they offer enormous potential in applications where impact resistance is critically important, such…
In this work different fabrication methods based on low cost lithographic techniques have been developed in order to create planar distributions of plasmonic nanostructures with tailored optical functionalities. In order to achieve sharp Localized Surface Plasmon Resonance (LSPR) resonances in the visible and IR range…
Discovery of novel materials with specific functions and development of enhanced fabrication processes are the key challenges facing nanotechnological research. Herein, fundamental understanding from the bottom-up design of metal-organic frameworks (MOFs) towards the exploiting of the enhanced liquid-phase epitaxial p…

The influence of long-term seawater immersion on the mechanical properties of plain woven CFRP laminates was evaluated by static tensile and tension fatigue tests. These tests were carried out on the CFRP immersed different time under seawater: 2566 hours and 4967 hours. The mechanical properties of the specimen for 2…
We report on morphology and optical properties of Cd0.55Mn0.45Te substrates annealed in the air at 650 °C. The AFM images reveal the presence of roughly pyramid-shaped grains with the size of the base of about 2-5 μm, formed by the smaller nano-scale pyramidal formations with characteristic dimensions of 10-100 nm. Th…
The nucleon form factors have been investigated by physicists for decades because of its fundamental importance. The world data of the proton magnetic form factor GMp shows that the measurements have been focused on Q2 lower than 5 GeV2 and it has large uncertainties at higher GeV2. Experiment E12-07-108 aims to impro…

It is a great pleasure to held the 14th International Biophilia Rehabilitation Conference (14th IBRC) in Ustron, Poland, on October 6-7, 2017.
Strontium hexaferrite is a chemically stable and cheap magnetic compound, free of rare-earth metals. Previous studies have shown that nanostructuring can improve the magnetic performance of strontium hexaferrite, both as a powder and after pellet compaction, which allows for better bulk magnets for use in for instance…

An understanding on crystallization behavior and kinetics in glasses is one of the important topics in the glass science and technology. Tsukada et al.1) found an extremely unique and curious phenomenon in the crystallization of multiferroic (ferroelectric and ferroelastic properties) ’-Gd2(MoO4)3 crystals in Gd2O3-M…
Two rate-independent strain gradient crystal plasticity models are developed and applied in numerical studies designed to identify the properties inherent to model predictions of plastic deformation. The two models incorporate gradients of slip into the framework of conventional crystal plasticity in order to model si…
A comparison of CoNi-CeO2 bimetallic catalyst with Co-CeO2 and Ni-CeO2 monometallic catalysts for the dry reforming of methane (DRM) was carried out in order to highlight the effect of Co on activity and on catalyst deactivation due to carbon deposition. Catalysts were characterized by temperature programmed reduction…
Providing surface texture on sliding surface is one of the way to control lubrication properties. Expected effects of surface texture include improving the hydrodynamic load capacity, preventing lubricant starvation and promotion of running-in. In the case of a flat slider bearing, it is known that slight crowning sha…
