Silicon-based electrode is a promising candidate in lithium-ion batteries (LIB) due to its significantly higher gravimetric capacity (3579 mAh g-1) in comparison to that of graphite (372 mAh g-1). However, during the process of lithiation/delithiation, the silicon material suffers from a huge volume change which has a…
Single-walled carbon nanotubes exhibit photostable near-infrared photoluminescence with excitation and emission energies that respond to fluctuations in the micro-environment. In the creation of robust nanotube-based optical sensors, it is desirable to identify shifts in excitation and emission of an ensemble nanotube…
Analysis of the group stages of the preparation process for the body parts has shown that the existing methods of design does not account a number of factors that give rise to unacceptable deviations (potential failure) the output process parameters. Algorithm design of group process with the use of methods of "Analys…
Electrically conducting polymers (ECP) showing pseudo-capacitive property are actively researched as supercapacitor electrodes for energy storage. Nanocomposites with structured carbons contribute additional charge storage through electric double layer component enhancing the charge storage ability. The nanocomposites…
Magnesium and its alloys are the lightest constructional available materials on earth with a maximum density of 1.78 g /cc and melting point of 650 ͦC, with good damping characteristics. Therefore; they are alloyed or micro alloyed with other elements. In this paper comparison between the addition of Ti and Ti+ B to t…
The gallium nitride (GaN) semiconductor market continues to rapidly expand because GaN device technology offers considerable performance advantages compared to gallium arsenide (GaAs) and silicon (Si) devices. GaN has inherently higher breakdown field strength, charge density, and electron velocity at high voltage. Th…
In a typical all-vanadium redox flow battery (VRFB), species crossover through membranes not only deteriorates cell performance, but also reduces battery’s lifetime. To address this issue of species crossover, a better understanding of the ion transport behaviors through an ion exchange membrane is essential. The fixe…
The self-assembly of metal chalcogenide tetrahedral clusters can lead to a family of porous semiconducting materials with uniform pore sizes and high surface area. The single-sized tetrahedral clusters act as building blocks to form well-ordered three-dimensional superlattices in the presence of either organic or inor…
Two different approaches have appeared in the literature in order to derive transport equations for coupled diffusion and stress in lithium host materials. The first approach is taken from solid mechanics and is described in detail, for example, in the work of Larché and Cahn [1] or in the reference text by Gurtin et…
Si has been widely recognized as one of the most promising anode materials for its high energy density; however, critical drawbacks such as large irreversible capacity decay and poor reliability/durability over extended cycles have significantly constrained its commercialization in many long duration, heavy duty appli…

Recently several research groups have demonstrated accurate placement of graphene on hexagonal BN (hBN) with crystallographic alignment. Due to the resulting superlattice formed in the graphene/hBN heterostructures, an energy gap, secondary Dirac Points, and Hofstadter quantization in a magnetic field have been observ…
Extensive efforts have so far been devoted to mimic light harvesting and charge separation processes in natural photosynthesis.1 Multiporphyrin arrays have been employed as light-harvesting units. Light-harvesting and charge-separation units have been combined by coordination bonds between metalloporphyrins and electr…
Niobium oxide/carbon (Nb2O5/C) composites were synthesized in a one-pot process by combining electrochemical exfoliation of graphite with anodic deposition of niobium oxide. The purpose of this study is to develop an electrolyte system that includes a precursor for oxide deposition as well as graphite exfoliation agen…
Durable ceramic waste forms that incorporate a wide range of radionuclides have the potential to broaden the available disposal options and to lower the storage and disposal costs associated with advanced nuclear fuel cycles. Ceramic waste forms have also been studied because of their superior chemical durability and…
Graphene, thanks to its novel properties, has proved to be a very good material for electronics applications, spacing from MEMS to biosensing technology. In the last few years chemical vapor deposition of organic precursors onto transition metal supports revealed to be a trustworthy method for high quality graphene de…
To explore the relationship between the properties of the PTFE micropowders and the irradiation conditions, several PTFE micropowders were prepared by electron beam irradiation from 5 to 4000 kGy in air at room temperature. The properties of the irradiated PTFEs were characterized by particle size and its distribution…
A chemical mechanical planarization (CMP) of copper (Cu) damascene structure is prone to defect formation due to variety of chemical agents in slurry and chemical complex formation. In post CMP cleaning process, which should remove such defects, a mechanical scrubbing of wafer by porous and elastic brushes are eligibl…
Three-dimensional metal micro- and nanostructures offer opportunities to develop multifunctional materials with unique combinations of material properties. Traditional strategies to improve the mechanical properties of materials consist of altering either the microstructure or the composition. Both strategies, albeit…
Light-induced substrate transformations in artificial photosynthetic devices and functional enzyme model systems strongly depend on the feasibility of multielectron transfer catalysis [1,2]. The crucial advantage of coupling multiple redox equivalents and proton transfer steps in photocatalysis is to avoid free radica…
