The aim of this study was to deyelop a noyel hydroxyapatite (HA) coating method on zirconia using glass coating technique. A borosi)icate glass, the mixture of the glass ttnd HA (3e, 50, 70, and 90 mass%), and the 100% HA were coated on two kinds of zirconia discs and fired at 900-950'C. After the final coating, the surface of the sample was etched for 3 min in an acid-mixture of 3% HF and 5%HN...

The mechanical design for both the insulating vacuum system and the cavity vacuum system of the APT ED&D Cryomodule is summarized. The pre-cooldown pressure limits for the insulating vacuum and the cavity vacuum are 10 -5 Torr and 10 -6 Torr, respectively. In addition, the cold cavity operating pressure limits are 10 -6 Torr for the insulating system and 10 -8 Torr for the cavity system. The de...

Interdigitated electrolyte-conductivity sensors with an added top layer of insulating Ta2O5 have been realized. The electrodesubstrate structure under the Ta2O5 film has been planarized in order to obtain a totally flat top surface. In addition, the electrodes have been applied on a totally insulating substrate, thus reducing the parasitic sensor capacitance by a factor of ten. © 1997 Elsevier ...

Interfacial phase change memory (iPCM) is magnetic sensitive at room temperature while the alloy with same composition is not. The unique property has been thought to be related to the topological insulating property. We discuss the magnetic properties on the point of view of the spatial inversion symmetry of iPCM structures and ferroelectricity of GeTe layers sandwiched by topological insulati...

Using the dynamical mean field theory it is shown that interorbital Coulomb interactions in nonisotropic multiorbital materials give rise to a single Mott transition. Nevertheless, narrow and wide subbands exhibit different excitation spectra in the metallic and insulating phases. The close analogy between "multigap" insulating behavior and multigap superconductivity is pointed out.

BACKGROUND Accidental hypothermia increases mortality and morbidity in trauma patients. Various methods for insulating and wrapping hypothermic patients are used worldwide. The aim of this study was to compare the thermal insulating effects and comfort of bubble wrap, ambulance blankets / quilts, and Hibler's method, a low-cost method combining a plastic outer layer with an insulating layer. ...

Magnetoresistance is an important material property that is utilized in electronic compasses, hard disk drives, biosensors, and microelectromechanical systems (MEMS). In normal (nonmagnetic) conductors, magnetoresistance is a variation of the resistance that occurs when an external magnetic field influences how electrons flow through the material. In magnetic conductors, the magnetoresistance d...

The development of obesity may be aggravated if obesity itself insulates against heat loss and thus diminishes the amount of food burnt for body temperature control. This would be particularly important under normal laboratory conditions where mice experience a chronic cold stress (at ≈20°C). We used Scholander plots (energy expenditure plotted against ambient temperature) to examine the insula...

in this research controlled coating of magnetite (fe3o4) nanoparticles with sio2 was investigated. the fe3o4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to stober method. effects of tetra ethyl ortho silicate (teos) concentration and ethanol to teos on the coating thickness were investigated. x-ray powder diffraction, fourier transform infrar...

One-dimensional (1D) electron-hole (e-h) systems in a high-density regime is investigated by means of bozonization techniques. It turned out that the systems are insulating even at the high density limit and that the exciton Mott transition (insulator-to-metal transition) never occurs at absolute zero temperature. The insulating ground state exhibits a strong instability towards the crystalliza...
