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

Advanced 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 ...

Computation of incompressible viscous flows through artificial heart devices with moving boundaries [PDF]

The extension of computational fluid dynamics techniques to artificial heart flow simulations is illustrated. Unsteady incompressible Navier-Stokes equations written in 3-D generalized curvilinear coordinates are solved iteratively at each physical time ...

On the valves of the heart [PDF]

Abstracts of the Papers Communicated to the Royal Society of London
The paper contains observations upon the structure and connections of the auriculo-ventricular and arterial valves of the human heart, which the author thinks will assist in explaining their nature and functions. The relation of the “four orifices” in the base of the heart is examined, and it is shown that the aortic and left auriculo-ventricular ...

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

Advanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Multimodal In‐Sensor Computing with Dual‐Phase Organic Synapses for Wearable Fitness Monitoring

Advanced Materials, EarlyView.
A dual‐phase organic synaptic sensor detects human respiration and ambient UV light, enabling a wearable neuromorphic system for real‐time exercise monitoring. Abstract With the advancement of wearable and mobile devices, demand for the real‐time, low‐power processing of physiological and environmental signals is growing rapidly.

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics

Advanced 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 ...
