Semi-interpenetrated Hydrogels Composed of PVA and Hyaluronan or Chondroitin Sulphate: Chemico-Physical and Biological Characterization
Physical hydrogels based on poly (vinyl alcohol) (PVA) were synthesized in the presence of natural polysaccharides, either hyaluronan or Chondroitin sulphate, in order to obtain versatile biomaterials with enhanced performances. The physical network is obtained by the freeze thawing technique, a simple method widely u…
Near-Field Optical Microscopy of Localized Surface Plasmons Excited in Noble Metal Nanostructures
Scanning near-field optical microscope is able to achieve a nanometer spatial resolution, and is useful for visualization of elementary excitations in nanomaterials. Combination of the near-field optical microscope with the time-resolved spectroscopy enables us to visualize spatio-temporal behaviors of the excited sta…

Interaction lumière matière avec des ensembles atomiques
L'étude de l'intéraction lumière matière avec des ensembles atomiques est un domaine de recherche actif. Ce type de système permet des études fondamentales sur la mesure dans le contexte de variables continues, l'intrication collective, et les simulations quantiques. Ce domaine de recherche est également intéressant d…

Performance and mechanism on a high durable silica alumina based cementitious material composed of coal refuse and coal combustion byproducts
Coal refuse and combustion byproducts as industrial solid waste stockpiles have become great threats to the environment. Recycling is one practical solution to utilize this huge amount of solid waste through activation as substitute for ordinary Portland cement. The central goal of this dissertation is to investigate…
Development of indicators system of NPP safety
В данной статье рассмотрена проблема оценки состояния атомных электростанций. Предлагается система показателей безопасности, которая позволила бы решить эту проблему. Рассмотрена иерархическая структура разрабатываемой системы показателей безопасности, а так же каждый индикатор в отдельности
Recrystallisation in a rapidly annealed low cost β-titanium alloy
This study investigates the recrystallisation behaviour of cold drawn low cost beta (LCB) Ti-1.5Al-6.8Mo-4.5Fe-0.2O (wt.%) by tracking the evolution of its microstructure and microtexture during rapid resistance annealing. The studied material was solution treated at 850oC for 1800 s, followed by water quenching, then…

Optical and Electro-optical Properties of Nematic Liquid Crystals with Nanoparticle Additives
Liquid crystals (LCs) are an interesting class of materials that are attracting significant attention due to their ever-growing applications in a wide variety of fields such as liquid crystal display (LCD) technology, materials science and bioscience. In recent years, along with the developments of materials at the na…
Fast and Reversibly Swtichable Wettability Induced by Photothermal Effect
We prepared the smart surfaces capable of fast switching between hydrophilic and hydrophobic states by visible light irradiation. For this purpose, we first prepared rough surfaces on a silicon wafer by using the layer-by-layer (LBL) deposition. The substrate was alternately immersed into an aqueous solution with poly…
INFLUENCE OF ASSEMBLY TECHNIQUES ON THE STATIC STRENGTH OF INTERFERENCE FIT AND ADHESIVELY BONDED PIN AND COLLAR SPECIMENS
Several characterizations of shaft-hub interference fit and adhesively bonded joints (Hybrid Joints) can be found today in literature, both for static and fatigue applications. However, a lack of information is still present about the influence of the assembly technique on the structural response of the joined parts.…
