Sieving Hydrogen Isotopes via Machine Learning Assisted Chemical Vapor Deposition (CVD) of High‐Quality Monolayer Hexagonal Boron Nitride (h‐BN) on Iron Foils

open access: yesAdvanced Materials, EarlyView.
Sub‐atomic scale separation of hydrogen isotopes (H+/D+) require near pristine h‐BN membranes, and scalable synthesis of such high‐quality h‐BN comparable to mechanically exfoliated crystals remains a significant challenge. This study reports a scalable Fe‐catalyzed Machine‐Learning Enabled Chemical vapor deposition process for bottom‐up large‐area ...

klf2a couples mechanotransduction and zebrafish valve morphogenesis through fibronectin synthesis

open access: yesNature Communications, 2016
In the developing heart, blood flow transmits mechanical signals to progenitor cells that ultimately leads to valve formation. Here, the authors identify the origin of the valve progenitor cells and fibronectin1bas a transcriptional target of the ...

Mechanical heart valves and pregnancy

open access: yesJRSM Cardiovascular Disease
Pregnancy is an exciting time, with great anticipation of the future for the woman and her baby. However, for women with mechanical heart valves (MHVs) pregnancy is a challenging undertaking fraught with risk to them and their baby. This article considers the issues for the woman, highlighting pre-surgical opportunities, pre-pregnancy counselling, the ...

Biaxial Mechanical Characterizations of Atrioventricular Heart Valves

open access: yesJournal of Visualized Experiments, 2019
Extensive biaxial mechanical testing of the atrioventricular heart valve leaflets can be utilized to derive optimal parameters used in constitutive models, which provide a mathematical representation of the mechanical function of those structures. This presented biaxial mechanical testing protocol involves (i) tissue acquisition, (ii) the preparation ...

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics

open access: yesAdvanced Materials, EarlyView.
Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...
