Abstract Highly birefringent liquid crystals have been desired recently by many applications in visible, infrared and recently other spectral regions such as THz and GHz as a active medium for various devices fabrication. For the broad temperature range of the nematic phase mixture formulation several structurally dif…
A facile impregnation method under mild condition is designed for synthesis of highly dispersed Pt nanoparticles with a narrow size of 4–7 nm on nitrogen-doped carbon nanotubes (CNx). CNx do not need any pre-surface modification due to the inherent chemical activity. The structure and nature of Pt/CNx were characteriz…
Exfoliated and partially oxidized MoS2 nanosheets as a hole extraction layer for efficient and stable organic solar cells (OSCs) is reported on page 2319 by H.-I. Joh, and colleagues. Incorporation of a simply prepared MoS2 nanosheet by solution-processing into OSCs dramatically increases the cell efficiency and devic…
Nanoparticles have recently been investigated as a possible way to improve absorption of light in solar cells. The strong interaction of nanoparticles with light allows control over the propagation of light at the nanoscale and thus, the design of solar cells, in which the light is trapped in an active layer and effic…
MAPPER Lithography is developing a maskless lithography technology based on massively-parallel electron-beam writing in combination with high speed optical data transport for switching the electron beams. With 13,260 electron beams further on split in 49 sub beams, each sub beam delivering a current of 0.3nA on the wa…
Optimized conditions for conventional thermal processing of Cu2ZnSnSe4are not readily transferable to the rapid thermal processing, though it is of high importance to test the industrial viability of this material. Here the effect of layer order has been investigated for Cu-Zn(O)-Sn precursor stacks selenized by rapid…
DNA biosensors has received significant attention. In particular, we can mention the model of a graphene-based DNA sensor which is used for electrical detection of DNA molecules. In this paper, we consider a method of selection of PSO parameters for optimization of the analytical model of a graphene-based DNA sensor.…
The mathematical model of soot dynamical evolution process is built based on the discrete particles population balance theory, including particle nucleation, collision coagulation, oxidation and surface growth processes; a corresponding numerical model is established using Lagrange interpolation method of moments. Bas…
The primary motivation for using silicon carbide rather than zirconium alloy cladding is its putative improvement in accident resistance, due to slow reactions with water, even at high temperatures. But, fuel management performance will also be an important consideration in its commercial acceptance. Whether backfitta…
TiN/HfO2/Pt resistive switching (RS) devices were fabricated with TiN top electrodes deposited in various Ar:N2ambient. Strong relevance between ambient Ar:N2ratio and electrical performance was demonstrated. This correlation was attributed to the difference in TiN crystal orientation, which has strong dependence on a…
Plasmonic enhancement of near infra-red to visible upconversion could potentially yield high-efficiency spectral converters for solar cells. We use spectroscopic imaging to investigate the intensity enhancement and modification of radiative rates of infra-red to visible upconversion from rare-earth doped nanoparticles…

The dynamic behavior of circular straight and stepped tubes made of aluminum alloy under high-velocity impacts was investigated by performing finite element analyses (FEA) and an experiment. The FEA and experiment on the straight tubes suggested that while an increase in the impact velocity enhanced the absorbed energ…
The process of commercial cement grinding in a helium atmosphere has been investigated in comparison with the process in an air atmosphere. Raw material particles have been sorted by sizes. Curves of helium release from the raw material after its grinding in air and in helium in the temperature range T = 20–1200°C hav…
A high precision selective harmonic compensation scheme for active power filters (APF), which was designed by using the basic theory of generalized predictive control (GPC), is proposed in this paper. A transfer function model -based GPC strategy is adopted. The strategy can compensate the delay in detecting the harmo…
The impact of junction formed by the electrode and bulk in phase change memory to conduction at the amorphous high resistance state is studied in this paper. Analytical model deduced from basic physical equation elucidates that the current changes from junction barrier limited to bulk barrier limited when the applied…
In the induction heating, in the calculation of the electric machines losses, in the mechanical engineering, in the calculation of the thermal field distribution, the equations of Maxwell and heat equation are required. Those utilize the magnetic permeability and the calorific capacity at constant volume which strongl…
The conducting polymers are vital sources for fabrication of micro electronics chips, GMR sensors, membranes and flexible electrodes. Polyaniline is widely chosen for such products because of its conductivity range. This paper focuses on the studies of dual phase properties of Polyaniline (PANI) - Magnetic Iron Oxide…
