MBE fabrication of Mnx P nanowhiskers
(2008)
MnP and MnP nanowhiskers have been grown by molecular-beam epitaxy (MBE)
technique on InP(100) and GaAs(111)B substrates. The catalyst-free growth of nanowhiskers
is found to be depended on the formation of Mn-based ...
Electron Microscopy of MgB2 Thin Film on YSZ-buffered Hastelloy
(Elsevier, 2004-06-11)
In order to understand the relationship between the microstructures and superconducting properties of MgB2 films, analytical TEM observations have been carried out. The films were fabricated by a KrF excimer laser deposition ...
Relationship between microstructure and Jc property in MgB2/α-Al2O3 film fabricated by in situ electron beam evaporation
(IOP, 2005-08-09)
A transmission electron microscopy (TEM) study has been carried out on an MgB2/α-Al2O3 film that exhibits the typical property of critical current density (Jc) under magnetic fields. The MgB2 layer of 300 nm in thickness ...
Transmission electron microscopy analysis of C4H4S-doped MgB2 tapes
(IOP, 2008)
It has been reported that doping with aromatic hydrocarbons in an in situ powder-intube
fabrication process of MgB2 tapes is effective for increasing the critical current density (Jc) under magnetic fields. In this study, ...
Tin Whisker Formation on a Lead-free Solder Alloy Studied by Transmission Electron Microscopy
(IEEE, 2006-12-06)
Tin whiskers grown on a Sn/Cu-plated Polyimide (PI)-flexible substrate are a serious problem in electronic industrial application, because the whiskers lead to catastrophic electrical short circuit failures. Here, we report ...
Transmission Electron Microscopy of Spontaneous Tin (Sn) Whisker Growth under High Temperature/Humidity Storage
(IEEE, 2008-12-09)
The present work is devoted to characterize the microstructures of Sn/Cu lead-frame attached on the printed circuit board (PCB) and of tin-whiskers formed on the Sn-surface after exposure under 85C/85 %RH for 1000 and ...
Effects of Post-Plating Reflow on Changes in Crystal Grain Size of Sn-2 mass% Bi Alloy Plating with Thermal Cycling Treatment
(The Japan Institute of Metals and Materials, 2010-10-01)
Changes in the grain size of tin (Sn) crystals associated with a thermal cycling treatment were investigated for layers of Sn-2 mass%Bi electroplated on Fe-42Ni substrates in order to clarify the effects of post-plating ...
Fabrication of Multilayered MgB2/Ni Thin Films and Their Flux Pinning Properties
(IEEE, 2009)
We prepared the multilayered MgB2/Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The
multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The ...
Gap Analysis of Human Resources Management and Performances of PKU Muhammadiyah Yogyakarta Hospital Unit II
(IIARD Publishing Co, 2016)
Abstract
Background: Issues of ASEAN Free Trade Area (AFTA) and globalization of the world economy demands which is every profit and non-profit organizations to compete in marketing and resource. The changes, requires ...
Effect of Ball-Milling Treatment on Microstructure of in situ Powder-in-Tube (PIT) MgB2 Tape
(American Institute of Physics (AIP), 2012-06-25)
In an in situ powder-in-tube (PIT) fabrication of MgB2 superconducting tapes, it has been found that ball-milling treatment on a starting powder is effective for improving critical current density (Jc) of the MgB2 tapes. ...
