A butyl methacrylate (BMA) monolithic column was polymerized in-situ with UV irradiation in an ultraviolet transparent PDMS micro-channel on a homemade micro-fluidic chip. Under the optimized conditions and using a typical polymerization mixture consisting of 75% porogenic solvents and 25% monomers, the BMA monolithic column was obtained as expected. The BET surface area ratio of the BMA monoli...

OBJECTIVE This study tested whether the two-body wear of monolithic zirconia and their corresponding enamel antagonists was higher compared to monolithic alloy and veneered zirconia. MATERIALS AND METHODS Cylindrical specimens (N = 36, n = 6) were prepared out of (A) veneered zirconia (VZ), (B) glazed zirconia using a glaze ceramic (GZC), (C) glazed zirconia using a glaze spray (GZS), (D) man...

Atom and, more recently, molecule interferometers are used in fundamental research and industrial applications. Most atom rely on gratings made from laser beams, which can provide high precision, but cannot reach very short wavelengths require complex systems to function. Contrary this, simple monolithic cut single crystals offer (sub) nanometer with an extreme level of stability robustness. Su...

In this project a number of circuits [1-4] with the characteristics of a passive inductor are to be assessed for their suitability for implementation in MMIC applications as a means of introducing a tuning function and as a replacement for the conventional passive inductor.

We have studied the reliability of intrinsic SiN MIM capacitors designed for 48 V and 125 0 C operation and manufactured in a GaN process flow. It is shown that very small area capacitors (10um x 10um) with a dielectric thickness of 400nm exhibit lifetimes as long as 1.48E10 hours under such conditions.

A S-band monolithic integrated switched filter bank has been designed to realize tunable working center frequency, and a tuning range of 12.9% from 2.7 to 3.05GHz was achieved with interval of 50MHz. The switched filter bank is designed using 8 eighth-order step impedance resonators (SIR) band-pass filters arranged in parallel rows. Microelectromechanical Systems (MEMS) switched circuit is inte...

Pixel Detectors, as the current technology of choice for the innermost vertex detection, have reached a stage at which large detectors have been built for the LHC experiments and a new era of developments, both for hybrid and for monolithic or semi-monolithic pixel detectors is in full swing. This is largely driven by the requirements of the upgrade programme for the superLHC and by other colli...

Sub-picosecond optical pulses have been successfully generated using a novel monolithic passive colliding pulse mode-locked (CPM)l semiconductor multiple quantum-well (MQW) laser. Transform-limited pulse width of 830 femto-seconds is achieved at a wavelength of 1.5pm and a repetition rate of 80 GHz. The measured timebandwidth product is 0.31. A record high repetition rate of 350 GHz is also dem...

Monolithic supports are efficient stationary phases for most of the important chromatographic separation modes. They can be applied for the chromatographic separation of biomolecules, nanoparticles, proteins, peptides, nucleic acids and low molecular mass organic acids. At the industrial level, monolithic chromatography is frequently used for the purification of large plasmids and bacteriophage...
