Ultrasound Measurements, Physico‐Chemical Characterization and Biological Evaluation of Magnesium Hydroxyapatite for Biomedical Applications

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT In this study, 15MgHAp (xMg = 0.15) was synthesized by an adapted method, lyophilized, and characterized to evaluate its physicochemical and biological properties. The ultrasound measurements (US) evaluated the stability of the resulting MgHAp gel. Complementary surface information was obtained using a scanning ultrasonic microscope (SUM). The

Dynamics of a Rod Attached to a Rotating Hinge

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT The dynamics of a rod attached to a rotating hinge, also interpreted as a physical pendulum in a rotating frame, provide a valuable mechanical model for analyzing the complex oscillatory behavior of helicopter rotor blades. This simplified system captures essential features of blade flapping and in‐plane motions influenced by inertial and ...
