איתן,
לאיזה סוג של אישור את ממתין?
אתה מוזמן לשלוח לו דגמים לקלורמטריה - נראה גם לי שנלמד מזה משהו, ולגבי רזוננס אולטראסאונד, בזבנו בדקנו את השיטה ללימוד של נזקי קרינה.
זו מערכת בפותחה בלוס אלמוס (נדמה לי) והיה קושי רב להוציא ממנה את הקבועים האלסטיים. המערכת מודדת רזוננסים (ולכן הוא מבקש דגים ספציפיים) ועל בסיס מודל מחשבים את הקבועים.

Dear Eitan,
Great to hear from you too! Hope the vaccines can be game changes if we have a wider public acceptance, which is an issue here in US.
For the samples you mentioned, in fact, we are certainly very interested in the additive materials! As you are familiar with the calorimetry, we can do the DHf of them. In additional, I recently developed the resonant ultrasonic spectroscopy (RUS) capability, from which one can know the elastic constants and I am pushing the system for studying temperature in situ to 1000 C. What information you would like to know about the samples? We only need ~ 100 mg of samples for calorimetry and a high symmetric shape dense sample (cube or cylinder) for RUS.
Looking forward to hearing from you and again best wishes to you and your family,
Xiaofeng

It is a pleasure to hear from you!
As 2020 just finally left, I wish you and your family a happy and fruitful new year.
If you will ever need some printed metal samples (SS or Ti) please let me know :-)
Best wishes
Eitan
