We generate squeezed state of light at 860 nm with a monolithic optical parametric oscillator. The optical parametric oscillator consists of a periodically poled KTiOPO(4) crystal, both ends of which are spherically polished and mirror-coated. We achieve both phase matching and cavity resonance by controlling only the temperature of the crystal. We observe up to -8.0±0.2 dB of squeezing with th...
A high-performance liquid chromatography method using a commercially available silica monolithic column for the simultaneous analysis of nanoparticles and small molecules was developed. The method uses the micrometer-sized flow-through pores and nanometer-sized mesopores of the monolithic column for separation: first, size separation of nanoparticles was performed by the micrometer-sized pores ...
Monolithic integrated millimeter-wave circuits based on silicon and SiGe are emerging as an attractive option in the field of millimeter-wave communications and millimeterwave sensorics. The combination of active devices with passive planar structures, including also antenna elements, allows single-chip realizations of complete millimeter-wave front-ends. This paper reviews the state-of-the-art...
The monolithic column is a single piece of a continuous rigid porous polymer that possesses an interconnected skeletal structure and contains pores. According to their components, monolithic materials can be divided into organic polymer-based monoliths and inorganic silica-based monoliths. This review focuses on silica-based monolith with special emphasis on the preparation. Moreover, this revi...
New Media Art reflects the dramatic creative and cultural shifts in science technology of past century. With these shifts, multitude forms art-making have expanded to include a wide range ideas techniques. Following several decades new contributions, this plurality expression has resisted monolithic or curatorial approaches organization along lines media. This paper defines knowledge cultures a...
Recently there is significantly increasing interest in the development of THz devices and circuits. Different from the MMIC device and circuit technologies, THz devices approach to the electrical limit of semiconductors and passive THz circuit elements have much less dimension tolerance. Therefore, device and circuit technologies concerning to such limitations have to be reconsidered and modifi...
We propose a generic architecture to facilitate the systematic design of autonomous, adaptive and safe applications. We specify generic modules including a trustworthiness enforcement layer dedicated to ensure the system’s functional stability as seen by the human owner. Instead of building a monolithic system, we encourage modularization based on the cognitive function of the components. A key...
A monolithic stationary phase was prepared for liquid chromatography by in situ copolymerization of pentaerythritol triacrylate (PETA) and triallyl isocyanurate (TAIC). The morphology of monolithic column and pressure drop across the column were characterized. The effect of the porogen on the pore structure was characterized by SEM. Under the comparison condition, the monolith was suceessfully ...
The use of monolithic high temperature superconductors in multipole configurations is analyzed in this paper. The properties of monolithic high temperature superconductors have been well documented, and monolithic tubes, disks and rods of different cross section and sizes can presently be obtained from several commercial vendors. In this paper, design issues of quadrupole magnets using single c...
