With the increasing density of components on Printed Circuit, Boards (PCBs) and the a.dvancement of fabrication technologies for multilayer PCBs, improvement of speed and techniques for the Computer Aided Design of multilayer PCBs has become a major area of research. The paper discusses the parallel processing of layering and routing algorithms for design of multilayer PCBs on a network of smal...

We report on a glucose oxidase (GOx)/polyelectrolyte (PE)/gold nanoparticle (AuNP) multilayer films that can be utilized as efficient glucose biosensors by layer-by-layer self-assembly method. Electrochemical impedance spectroscopy (EIS) and UV-visible spectroscopy were adopted to monitor the regular growth of the multilayer films. The role of gold nanoparticles integrated in the multilayer fil...

Piezoelectrics have been widely used in different kinds of applications, from the automobile industry to consumer electronics. The novel multilayer piezoelectrics, which are inspired by multilayer ceramic capacitors, not only minimize the size of the functional parts, but also maximize energy efficiency. Development of multilayer piezoelectric devices is at a significant crossroads on the way t...

We measured the low-temperature specific heat of a sputtered (Fe23Å /Cr12Å)33 magnetic multilayer, as well as separate 1000 Å thick Fe and Cr films. Magnetoresistance and magnetization measurements on the multilayer demonstrated antiparallel coupling between the Fe layers. Using microcalorimeters made in our group, we measured the specific heat for 4,T,30 K and in magnetic fields up to 8 T for ...

The capacitance and leakage current properties of multilayer La2O3/Al2O3 dielectric stacks and LaAlO3 dielectric film are investigated in this paper. A clear promotion of capacitance properties is observed for multilayer La2O3/Al2O3 stacks after post-deposition annealing (PDA) at 800 °C compared with PDA at 600 °C, which indicated the recombination of defects and dangling bonds performs better ...

Antibacterial multilayer films containing nanosilver were prepared via layer-by-layer fashion. PET film was aminolyzed with 1,6-hexanediamine to introduce amino groups on PET film surface; chitosan-silver nitrate complex and heparin were alternately deposited onto an aminolyzed PET film surface, and subsequently, the silver ions within the multilayer films were reduced with ascorbic acid to for...

A silicon photodiode coated with an interface-engineered Mo/Si multilayer was developed as a polarization sensitive detector. The Mo/B4C/Si multilayer was designed to reflect 13.5-nm extreme-ultraviolet (EUV) radiation at an incident angle of 45 degrees, at which the maximum polarization sensitivity occurs. The sensitivity of this specially coated photodiode and its polarization responses were ...

In this study, Pb(Zr0.52Ti0.48)O3/BiFeO3 [PZT/BFO] multilayer thin films were fabricated using the spin-coating method on a Pt(200 nm)/Ti(10 nm)/SiO2(100 nm)/p-Si(100) substrate alternately using BFO and PZT metal alkoxide solutions. The coating-and-heating procedure was repeated several times to form the multilayer thin films. All PZT/BFO multilayer thin films show a void-free, uniform grain s...

Abstract Recently, multilayer piping has been used widely. Multilayer piping has excellent durability and corrosion resistance. An effective means for quality maintenance of multilayer piping is the laser ultrasonic technique for checking the state of adhesion of the vinyl chloride layer and the steel layer of multilayer piping. The wave is refracted at the interface between the steel layer and...

The growth of various multilayer‐polymer multilayer‐nanoparticle films was successfully achieved. Multilayer‐polymer multilayer‐nanoparticle films with 1, 3, and 5 polymer layers between nanoparticle layers exhibit significantly different optical properties due to the differences in magnitude of particle plasmon coupling. These film systems were also successfully extended to hollow gold nanosh...
