Metal-Oxide-Semiconductor structures with silicon nanocrystals in the oxide layer are prepared and characterized by Transmission Electron Microscopy and electrical measurements. High temperature annealing of SiO1.15 films at 1000 °C for 30 or 60 min leads to formation of silicon nanocrystals with diameters of 2-3 or 4…
Cross sections for the ¹⁸O + ¹⁸O reactions (fusion, inelastic excitation and transfer reactions ) have been determined in the range 6.73 ≤ Ec.m ≤ 13.24 MeV by measuring the low- lying γ-ray transitions in the residual nuclei with a high resolution Ge detector. A statistical model calculation of the populations of the…

Duplex stainless steels (DSSs) fatigue crack propagation resistance isstrongly affected both by microstructure and environment. In this work, environmentinfluence on the fatigue crack propagation in a rolled 25 Cr 7 Ni superduplex stainlesssteel was investigated considering three different stress ratios (R = Kmin/Kmax…
We develop a new Voronoi protocol, which is a space tessellation method, to generate fully dense (containing no voids) nanocrystalline models of copper (Cu) with precise grain size control; we also perform uniaxial tensile tests using molecular dynamical (MD) simulations to measure the elastic moduli of the grain boun…
Metal foams have attracted wide range of interest from researchers and industries because of their unique combinations of properties. Of particular interest, open cell metallic foams have good weight-specific mechanical properties, and improvements could make these materials highly desirable for lightweight structural…
Under the assumption that superconducting pairing is driven by local d-p hybridization, we show that the superconducting state in iron-based superconductors is classified as an odd parity s-wave spin-singlet pairing state in a single trilayer FeAs/Se, the building block of the materials. In a low energy effective mode…
The main subject of this thesis is the structure and morphology control of colloidal polymer particles, in particular, poly(methyl methacrylate) (PMMA) particles, by dispersion polymerization in polar solvents. The structure control, ranging from surface morphology and internal structure to shape manipulation of polym…
Nanoscale thermal properties are becoming of extreme importance for modern electronic circuits that dissipate increasing power on the length scale of few tens of nanometers, and for chemical and physical properties sensors and biosensors using nanoscale sized features. While Scanning Thermal Microscopy (SThM) is known…
In this paper we extend the concept of bi-univalent to the class of meromorphic functions. We propose to investigate the coefficient estimates for two classes of meromorphic bi-univalent functions. Also, we find estimates on the coefficients |b0| and |b1| for functions in these new classes. Some interesting remarks an…
Advances in Kinetics and Mechanism of Chemical Reactions describes the chemical physics and/or chemistry of ten novel material or chemical systems. These ten novel material or chemical systems are examined in the context of various issues, including structure and bonding, reactivity, transport properties, polymer prop…
Inspired by the recent works of Srivastava et al. (HMS-AKM-PG), Frasin and Aouf (BAF-MKA) and others (Ali-Ravi-Ma-Mina-class,Caglar-Orhan,Goyal-Goswami,Xu-HMS-AML,Xu-HMS-AMC), we propose to investigate the coefficient estimates for a general class of analytic and bi-univalent functions. Also, we obtain estimates on th…
The technologies currently used for recuperating rubber are not very sophisticated: mainly ground or reclaimed rubber is used, both having a low quality compared to the original material 3,4 . Therefore, the material is mainly 'downcycled': it is used for low quality applications, for which the property requirements a…
The overall objective of this project is to conduct cost analyses and estimate costs for on- and off-board hydrogen storage technologies under development by the U.S. Department of Energy (DOE) on a consistent, independent basis. This can help guide DOE and stakeholders toward the most-promising research, development…

The production of smooth, densely-packed, and continuous casts of colloidal nanoceramics into architectures for applications ranging from anti-corrosion coatings to transparent optical components and devices is a rapidly developing field. Post-processing procedures, such as, sintering that can form single crystalline…
A prototype sensor able to work at zero bias has been fabricated using high quality single crystal diamond and two Schottky junctions. The detector's current in the dark is 3.2±0.2×10-14 A, while the current measured under irradiation with 1.6 Gymin-1 of 6 and 15 MV x-ray photons is 7.5±0.2×10-10 A. The sensitivity is…
Polyelectrolyte multilayers (PEM) built by layer-by-layer technique have been extensively studied over the last years, resulting in a wide variety of current and potential applications. This technique can be used to construct thin films with different functionalities, or to functionalize surfaces with substantial diff…
Hot-dip galvanizing is one of the most used methods to apply zinc-based coatings on steels, in order to provide sacrificial protection against corrosion over all the steel surface.The efficiency of the protection is affected by the coating mechanical response to loading: cracking and coatings delamination during formi…
