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 Multi Autolab M204 electrochemical workstation, a Wuhan Corrtest CS310H Potentialstat and a CS353 AC-impedance instrument, a Spectro XEPOS XRF, an ezHEMS800 Hall-Effect measurement system, a Parr-4791 high temperature & high pressure reactor, several furnaces for syntheses of samples, etc.
