We developed the 1T/1C FRAM device technology using 0.5 /spl mu/m design rule which is perfectly compatible with 0.5 /spl mu/m CMOS logic process. This technology achieves the small 1T/1C FRAM cell size of 12.5 /spl mu/m/sup 2/, and minimized process degradations of ferroelectric material characteristics using low-pow…
A solid state chemistry synthetic approach towards identifying new materials with potentially superior thermoelectric properties is presented. Materials with complex compositions and structures also have complex electronic structures which may give rise to high thermoelectric powers and at the same time possess low th…
The necessity to apply near-toxic amounts of radioprotective drugs to achieve adequate protection during radiation treatments represents a major problem in human medicine. One of the promising strategies to suppress the toxicity of these drugs involves their incorporation into biocompatible polymers. In this study cys…
Recent papers have covered the merits of using finite elements to calculate the thermoelectric device performance for steady-state conditions. Likewise, papers have covered the use of finite elements to model transient cooling conditions. It remains then to model power generation performance with finite elements and c…
Ultrathin ( d < 20 nm) films of cellulose were fabricated by regeneration of trimethylsilylcellulose films, which were deposited on silicon wafers by the Langmuir−Blodgett (LB) or the spin-coating method. Equilibrium film thickness with respect to relative atmospheric humidity was quantitatively measured by ellipsomet…
Argon plasma-pretreated poly(tetrafluoroethylene- co -hexafluoropropylene) (FEP) films were subjected to UV-induced surface graft copolymerization with acrylonitrile (AN). The AN graft-copolymerized FEP (AN-g-FEP) surface was further reacted with hydroxylamine to introduce amidoxime groups on the surface (the amidoxim…
Two tripodal ligands, bis(2-benzimidazolylmethyl)(2-pyridylmethyl)amine (L(1)) and bis(2-pyridylmethyl)(2-benzimidazolylmethyl)amine (L(2)), were synthesized. With the third chromophoric ligand antipyrine (Antipy), three series of lanthanide(III) complexes were prepared: [LnL(1)(Antipy)(3)](ClO(4))(3) (series A), [LnL…
The preparation of polyethylene- block -poly(ethylene- alt -propylene)- block -poly(ethylene oxide) (PE- b -PEP- b -PEO) triblock copolymers by homogeneous catalytic hydrogenation of the precursor poly(1,4-butadiene)- block -poly(1,4-isoprene)- block -poly(ethylene oxide) (PB- b -PI- b -PEO) triblock copolymers, which…
A 3D magnetostatics computer code optimized for Undulators and Wigglers is described. The code uses a boundary integral method and makes extensive use of analytical expressions for the field and field integrals along a straight line. The code outperforms currently available finite element packages in the area of simpl…
Methods for introducing new magnetic, optical, electronic, photophysical, or photochemical properties to semiconductor nanocrystals are attracting intense applications-oriented interest. In this communication, we report the preparation and electronic absorption spectroscopy of colloidal ZnO DMS-QDs. Our synthetic proc…
A synthesis of ordered biphenylene-bridged mesoporous material with a crystal-like periodic pore wall structure is reported.
A general peptide design is presented that links the pH-dependent intramolecular folding of beta-hairpin peptides to their propensity to self-assemble, affording hydrogels rich in beta-sheet. Chemical responsiveness has been specifically engineered into the material by linking intramolecular folding to changes in solu…
Carbon nanotubes can be functionalized via amidation and esterification of the nanotube-bound carboxylic acids. The solubility of these functionalized carbon nanotubes makes it possible to characterize and study the properties of carbon nanotubes using solution-based techniques. Representative results concerning the s…
The concept of global vacuum pressure impregnation has been in existence for many years and thousands of motors and generators have been manufactured by this process. Over the past 20 years the unit size of machines manufactured by this process has steadily increased until it is now common for generators having output…
The polyetherimide is an amorphous thermoplastic resin with a high glass transition temperature. It is characterised by high heat resistance and mechanical properties which make it suitable for industrial application. Two different polyetherimide (varying by the chemical formula) are investigated here, in term of thei…
Several different joint assemblies were evaluated in support of a manufacturing technology for diffusion bonding a beryllium armor tile to a copper alloy heat sink for fusion reactor applications. Because beryllium reacts with all but a few elements to form intermetallic compounds, this study considered several differ…
Thin films of ZnO were deposited by chemical bath deposition. The "as grown" films are amorphous or polycrystalline depending upon the chemical composition of the aqueous solution and the temperature used for their deposition. After a thermal annealing at temperatures above 300/spl deg/C, the films undergo a chemical…
This paper describes the investigation results of DC leakage currents and space charge distributions in the cable insulation performed to clarify the mechanism of the DC leakage current peak in 6.6 kV XLPE cables. These measurements were carried out at various amounts of residual by-product of crosslinking reaction. T…
This work presents a study of the sensitivity of some parameters in magnetic components and their influence on the value of their parasitics. The influence of the insulator thickness, the effect of the air gap, the window height and the variation of the value of the capacitive effects as a consequence of the coil-form…
The title compound, caesium aluminium dimolybdate(VI), CsAl(MoO4)2, belongs to the glaserite type family of double molybdates and tungstates. The crystal structure was studied by in situ X-ray single-crystal and powder diffraction at room temperature. The temperature dependence of the lattice parameters at low tempera…
