The effect of structural constriction on molecular mobility is investigated by broadband dielectric spectroscopy (BDS) within three types of molecular arrangements: monomers, oligomers and self-assembled monolayers (SAMs). While disordered monomers exhibit a variety of cooperative and local relaxation processes, the constrained nanodomains of oligomers and highly ordered structure of monolayers...

An approach of generating broadband Bessel beams is presented. The broadband Bessel beams are produced by a gradient index (GRIN) metamaterial lens illuminated by broadband waveguide antenna. The metamaterial lens is constructed with multi-layered structure and each layer is composed of GRIN metamaterials. The metamaterials are designed as dielectric plates printed with metallic patterns in the...

We outline the design of a scientiic visualization system based on a data card display invariant to provide information on the creation and processing of tasks in distributed task pool algorithms. Information aggregates over the tasks and processes are incorporated via non-classical histogram representations showing the distribution of the data within individual bins and by user-controllable tr...

Environmental noise restrictions play a role in the performance of wind turbines and the dominant source of noise on modern turbines is aeroacoustic noise produced by the blades. A 32 sensor acoustic array has been developed in cooperation between the National Renewable Energy Laboratory (NREL) and the University of Colorado to conduct measurements of aeroacoustic noise from a 100 kW wind turbi...

A transfer radiometer (TR) applied to an on-orbit radiometric benchmark chain has been developed, which can achieve the high-precision transformation of power and radiance responsivity transmit traced cryogenic remote sensors, such as imaging spectrometer, so that sensors high accuracy calibration 10−3 magnitude. Radiance comparison experiments between TR standard National Institute Metrology (...

The development of compact and bright XUV soft X-ray sources based on high-order harmonic generation is boosting advances towards understanding the behavior matter with extreme temporal spatial resolutions. Here, we report efficient inside microfluidic devices fabricated by femtosecond laser irradiation followed chemical etching. Our approach allows one to control manipulate conditions in gas a...

We have constructed a broadband apparatus for wavelength metrology capable of absolute accuracy at a level of better than 2 parts in 109. An evacuated plane-parallel Fabry–Pérot interferometer with continuously adjustable mirror separation is used to compare the wavelength of a single-frequency tunable laser with that of an iodine-stabilized HeNe laser used as a wavelength standard. This work d...
