Cardiomyopathies are serious heart muscle (myocardial) abnormalities which can lead to life-threatening complications such as heart failure, cardiac arrest, and sudden death. Myocardial biopsies obtained from surgical septal myectomies are essential for confirming diagnosis of cardiomyopathies. Owing to the recent advancements of synchrotron radiation-based X-ray phase contrast imaging (XPCI),...

Microtubules (MTs) are dynamic filaments involved in many essential cellular functions including those needed for cancer cell growth. Taxanes are MT stabilizing agents and the most successful antitumoral drugs targeting MTs. However, despite their mode of action is the stabilization (i.e., do not destroy the filament structure), they produce a paradoxical neurotoxic effect by inducing axon...

Chromium triiodide (CrI3) was the first layered van der Waals material to demonstrate the persistence of a sizable ferromagnetic hysteresis down to the monolayer [1]. This observation was accompanied by a striking transition from a layered ferromagnetic to a layered antiferromagnetic order as the number of layers of the crystal approached the two-dimensional limit [2]. The discovery of...
