High Temperature and High Resolution Observation EELS Analysis (HF-2200 TEM 114)

From Hitachi High Technologies America, Inc.
 

 
Carbon nano-tubes have been extensively studies worldwide. They are targeted on electron emitters and surface acoustic wave (SAW) filters in the field of electronics/information/communication and also on lightweight batteries and hydrogen storage materials in the field of energy. Transmission electron microscopes are one of the indispensable instruments needed for the study of carbon nano-tubes. These tubes, however, are sensitive to high energy electron beam irradiation so that they often change their micro-structures during observation. For high resolution microscopy and analysis of these tubes a high level of technical expertise was needed. There are two types of carbon nano-tubes; MWNT or multi-walled nano-tube and SWNT or single walled nano-tube. MWNT is composed of 2 to 30 layers of graphite sheets.

Distribution transformers are pole-type transformers that supply relatively small amounts of power to residences. They are used at the end of an electrical utility’s delivery system. Learn more about Distribution Transformers
Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications. Search by Specification | Learn more about Power Transformers
Voltage transformers and potential transformers are used to measure voltage in electric circuits. Their main role is to condition (step down) the voltage to be measured to levels suitable for the measuring instrument. Learn more about Voltage and Potential Transformers
Toroidal transformers typically consist of copper wire wrapped around a cylindrical core. This design prevents the magnetic flux that occurs within the coil from leaking. Search by Specification | Learn more about Toroidal Transformers
Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency. Search by Specification | Learn more about Pulse Transformers
