The World of Shape‐memory Alloys
Regarding Shape-memory Alloys (SMAs), Chang and Read were the first to detect a phase transformation in a Au-Cd alloy by metallographic observations and measurements of electrical resistance. “An overview of the basic metallurgy of commonly-used SMAs” has been written by Michel Morin. Only two categories of alloys are…
Orbital selective correlations between nesting/scattering/Lifshitz transition and the superconductivity in AFe1-xCoxAs (A=Li, Na)
The correlations between the superconductivity in iron pnictides and their electronic structures are elusive and controversial so far. Here through angle-resolved photoemission spectroscopy measurements, we show that such correlations are rather distinct in AFe$_{1-x}$Co$_x$As (A=Li, Na), but only after one realizes t…
Martensitic Transformation
This chapter is partly considered as an attempt to summarize the book by Kaushik Bhattacharya Microstructure of martensite: why it forms and how it gives rise to the shape memory effect. It begins by briefly outlining a few basic elements of linear algebra in relation to a certain orthonormal basis and a number of kin…
Ultra-shallow fluorine implantation from r.f. plasma as a method for improvement of electro-physical properties of MIS structures with PECVD gate dielectric layers
In this work a comprehensive analysis of changes in electrical and reliability parameters, which are introduced by the presence of a fluorine-rich layer in the gate structure based on MOS (Al/SiO2/Si) and MIS (Al/SiOxNy/Si) system, has been carried out. The surface of silicon substrates prior to the test structure exe…
The Corrosion Properties of Zirconium and Titatium Loadbearing Implant Materials with Protective Oxide Coatings
At present study the comparative analysis of parameters for oxide Al2O3 and ZrO2 films deposited by reactive magnetron sputtering (RMS) method on the load-bearing implant materials such as titanium-based (Ti4Al6V) and Zr has been made. The corrosion examinations of anodic polarization by potentiodynamic method, Tafel…
The Effect of Nitrogen Partial Pressure and Substrate Temperature on the Characteristics of Photocatalytic N:TiO2 Thin Films deposited by Filtered Vacuum Arc Deposition
Nitrogen doped Titanium Oxide (N:TiO2) thin films were deposited using filtered vacuum arc deposition, and their structure, composition and morphology were studied as functions of the total pressure, N2/O2 gas ratio and the substrate temperature. The film structure, surface morphology, and composition were determined…
Polymerization of Acrylic Acid by a 4kJ plasma focus device
The most conventional way for polymerization of acrylic acid on different substrates is using RF devices and introducing of other devices is under way. In this work we have a new study on formation of polymer Acrylic Acid using APF plasma focus device. The formation of plasma polymer acrylic acid is discussed using re…
High Power Density Pulse Magnetron Sputtering - Process and Film Properties
In this paper specific advantages and disadvantages of different pulse magnetron sputtering processes (unipolar and bipolar pulse sputtering at high and very high power density including HIPIMS) as well as current and potential fields of application will be discussed.
Spotless arc activated high-rate deposition using novel dual crucible technology for titanium dioxide coatings
For deposition of thin oxide coatings there are a lot of qualified PVD processes today. If high productivity or large-area coating is necessary for economic reasons processes with high deposition rate are reasonable. Using electron beam (EB) evaporation all inorganic materials can be evaporated with high rates. Micros…
Cr-DLC films deposited by dual pulsed laser ablation
Diamond-like carbon (DLC) and Cr doped diamond-like carbon (Cr-DLC) layers were studied for potential medical applications. DLC and Cr-DLC were deposited on silicon and titanium substrate by dual pulsed laser ablation using two KrF excimer lasers and two targets (graphite and chromium). The topology of layers was stud…
Preparation of the Elusive [(por)Fe(NO)(O‐ligand)] Complex by Diffusion of Nitric Oxide into a Crystal of the Precursor
Neutralkomplexe vom Typ [(por)Fe(NO)(O-Ligand)] wurden nach einer Kristall- Gas-Methode erhalten; [(por)Fe(NO)(OC(O)CF3)] enthält eine nahezu lineare Fe-NO-Einheit. Die Porphyrinmoleküle bewegen sich stark infolge der Diffusion von NO durch das Kristallgitter und seiner Koordination an Fe. Dichtefunktionalrechnungen…
ARTICLES 81 AND 82: ENFORCEMENT AND PROCEDURE
The examination of the substantive law of Articles 81 (formerly 85) and 82 (formerly 86) in the preceding chapters inevitably made reference from time to time to the procedural framework for the application of the Treaty competition rules. The Council was originally given powers under Article 87 (now 83) to adopt appr…
Self-Organized Nanostructures on GaSb(001) Surfaces Due to Low-Energy Ion Irradiation
Surface modification of GaSb(001) induced by low energy (2 to 4.5 keV) Ar ion beam irradiation has been investigated by means of atomic force microscopy (C-AFM). It has been found, that depending on the ion beam parameters, i.e. energy and fluence, narrow size distribution of nanostructure patterns have been developed…

GEOMETRICAL AND TRANSPORT PROPERTIES OF SEQUENTIAL ADSORPTION CLUSTERS
We investigate transport properties of percolating clusters generated by irreversible cooperative sequential adsorption (CSA) on square lattices with Arrhenius rates given by ki ≡ qni, where ni is the number of occupied neighbors of the site i, and q a controlling parameter. Our results show a dependence of the prefac…
Enhancement in external quantum efficiency of 365 nm vertical-type ultraviolet light-emitting diodes with embedded oxide structure
High performance 365 nm vertical-type ultraviolet light-emitting diodes (UV-LEDs) were developed using an embedded self-textured oxide (STO) structure using metal-organic chemical vapor deposition system. From etch-pit-density results, the dislocation densities of LED epilayers were effectively reduced to 5.6×106 cm-2…
High efficient InGaN blue light emitting diode with embedded nanoporous structure
We report a highly efficient GaN-based blue light-emitting diodes (LEDs) structure with an emitting wavelength of 450nm on flat sapphire substrate by utilizing a nano-porous (NP) GaN insertion layer. Unlike the LED on patterned sapphire substrates (PSS), the presented substrate has a new morphology which not only can…
