Research Facilities


We purchase from time to time scientific instruments to our HPSTAR labs, including shared large facilities (such as X-ray diffractometer, PPMS and Raman spectrometer) and instruments housed in PIs' individual labs. So far, our group has acquired an Agilent Cary 7000 UV-VIS-NIR spectrometer, an Agilent 8454 UV-VIS spectrometer, a Micrometrics NanoPlus-1 particle size analyzer, a Nanjing Dazhan DSC-100, a Wuhan Corrtest CS353 AC-impedance instrument, a Parr-4791 high temperature & high pressure reactor, several furnaces for syntheses of samples, etc.


 

Agilent Cary UV-VIS-NIR spectrometer; ZEISS microscopy


Micrometrics particle size analyzer; Agilent UV-vis spectrometer; Parr HTP reactor


We also make extensive use of  national and international synchrotron facilities for our research.
