Femtosecond lasers enable materials processing with their notably characteristics, such as precision, high peak density, flexible, and minor thermal affected zone. Applications ranging from high precision micromachining to biological manipulation with no thermal damages are possibly executed via this technology. In th…
Oxide monolayers and submonolayers formed by vapor deposition of In 2 O and SiO oxides on In As ( 001 ) - ( 4 × 2 ) were studied by scanning tunneling microscopy. At low coverage, In 2 O molecules bond to the edges of the rows and most likely form new In–As bonds to the surface without any disruption of the clean surf…

Bismuth ferrite (BiFeO3) is an attractive multiferroic material. However, its application as a ferroelectric material in electronic devices is limited by large leakage current. In this letter, a bipolar resistance switching phenomenon was observed in BiFeO3polycrystalline films prepared by sol-gel method. The resistan…

High-speed permanent magnetic generator (HSPMG) is common and important power production equipment in distributed generation systems. According to the structure characteristics of a 100kW level HSPMG, the mathematical model and physical models for its two-dimensional electromagnetic and thermal analyses are establishe…
A new type of 3,3'-(2-hydroxypropane-1,3-diyl) bis(azan-1-yl-1-ylidene)bis(2-(4-alkoxy phenyl)prop-1-en-1-ol) and their copper complexes were prepared and mesomorphic properties characterized. The mesomorphic properties of these copper complexes were studied by differential scanning calorimetry (DSC), polarized optica…
In recent years, there has been an increased demand for engineered materials that are lightweight, stiff and tough. Interpenetrating Phase Composites (IPC), a family of bio-inspired materials, made of two or more phases where each phase forms a continuous 3-D network throughout the volume of the material could address…
The efficiency droop effect of a light-emitting diode is significantly reduced through the coherent coupling of its emitting quantum wells with the surface plasmons generated on the fabricated Ag structure on the device top surface.
We have focused particular attention on the factors governing the creation of materials with intrinsically 1- and 2-D nanoscale infrastructures. Although some improvement in materials behaviour has already been achieved, it is unlikely that the technological paradigm shifts that N&N promise will be forthcoming until k…
We present a novel hydrogen sensor that is based on large arrays of chemically actuated electromechanical nanoswitches, realized by nanogaps in palladium (Pd). An individual switch consists of a trimorph poly-Si/Ti/Pd structure and a fixed Ti/Pd electrode, separated by an approximately 10-15 nm wide nanogap. The volum…
A new kind of triphenylene derivative sym-(OC3H6OCOC2H4COOH)6 with triphenylene at the core and carboxyl groups at the peripheral chains was synthesized and characterized by FT-IR and 1H-NMR. Thermal gravimetry analysis (TGA) and differential scanning calorimetry (DSC) showed that these compounds have a good thermal s…
Higher contamination flashover voltage of a semi-conducting glaze (SG) insulator owes primarily to the drying effect by leakage current flowing in the glaze. Significant reduction in contamination flashover voltage was confirmed on a cylindrical SG insulator when fog density was increased from 0.5g/m3 to 13g/m3 in cle…

We have investigated resonant nanocavities coupled to photonic crystal waveguides for biosensing. The devices are fabricated using electron beam lithography and reactive-ion-etching. Preliminary results demonstrate successful detection of human IgG molecules and refractive index sensing.
The high-temperature superconductor La1.84Sr0.16CuO4 is excited with high intensity terahertz pulses tuned to the 1.9-terahertz Josephson Plasma Resonance. The strong interlayer tunneling current modulates the microscopic properties of the superconductor.
In this paper, nonlinear vibration characteristics of a viscoelastic microplate under electrostatic actuation have been obtained. The microplate has been assumed as a CNT-reinforced simply supported square plate and an electrostatic actuation applied on it. The nonlinear equations of motion have been derived and solve…
Laser high-order harmonics are used to measure the optical constants of materials in the EUV. The optical constants for uranium, copper, and other metals are characterized from the measured ratio of s- vs. p-polarized reflectance.
Bismuth Titanate based electroceramics of layered perovskite structures are technologically important materials for high temperature piezoelectric and ferroelectric applications, due to their high Curie temperature (675° C), Stable piezoelectric response and excellent dielectric properties. The compounds ABi4Ti4O15 (A…
