Dynamic Elastic Modulus of Grinding Wheel

open access: yesJournal of the Japan Society of Precision Engineering, 1970
In this paper, the relation between the dynamic elastic modulus measured by ultrasonic pulse method and the grade of the grinding wheel is discussed.The results obtained are as follows: 1. The grade of the grinding wheel can be determined by the dynamic elastic modulus.2.

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

open access: yesAdvanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.
