"Dear Faculty,

Please join me on February 24^th for a talk from Dr. Zhu on the Angstrom method and its extensions as a solution for industrial-grade low dimensional thermal measurements. 

Best Regards,
Ray Baughman"

Abstract:
Low dimensional thermal measurement has always been challenging. What are the pros and cons of TDTR, Laser Flash, Raman, 3, T-type and thermal bridge method? What method is more convenient and robust for fiber or microscale fiber measurement? I think Ångström method may be one of them. In its original version (1861), a carbon fiber was the sample under test, and only the thermal diffusivity was measured. For over 100 years, its application has been limited to thermal diffusivity measurements. Based on that, we have developed a series of extensions to make this method more versatile, robust and convenient towards industrial use. Those extensions include Heat-loss modified Angstrom (also for thermal conductivity and specific heat measurements), micro-Angstrom (for microscale measurement) and FFT Angstrom (for fast measurement). I will demonstrate them and their applications in material studies.
