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.
Dr. ZHU is currently an Associate Professor of School of Microelectronics, Southern University of Science and Technology (SUSTech), Shenzhen, China. She received her bachelor (2006) and doctor (2011) degrees from Material Science and Engineering, Tsinghua University, Beijing, China. She was awarded National Outstanding Yong Scientist by NSFC in the field of engineering thermal physics (2021, 6 awardees per year).

Dr ZHU’s research interests center on micro- and nano- scale heat transfer: theory, measurement and simulation, Thermal management technology including materials, devices and systems. Dr. Zhu has 60+ publications in International Journal of Heat and Mass Transfer, Applied Thermal Engineering, Advanced Materials, Advanced Functional Materials, Advanced Optical Materials, The Journal of Physical Chemistry Letters, Scientific Reports, ACS Applied Materials & Interfaces, Nanoscale, Applied Physics Letters, etc., with H-index 23 and citations 1900+. Dr. Zhu also values the transfer and real use of technologies. She has filed 57 patents, among which 32 is granted and 9 is commercialized.
