Multifunctional Bio‐Based Packaging for Perishable Foods: Structural Design, Scalable Fabrication, and Versatile Applications

Advanced Materials, EarlyView.
An overview of design principles and scalable fabrication strategies for multifunctional bio‐based packaging. Radiative cooling films, modified‐atmosphere films/membranes, active antimicrobial/antioxidant platforms, intelligent optical/electrochemical labels, and superhydrophobic surfaces are co‐engineered from material chemistry to mesoscale structure

Heart Valve Tissue Engineering [PDF]

Circulation Research, 2005
Tissue-engineered heart valves have been proposed by physicians and scientists alike to be the ultimate solution for treating valvular heart disease. Rather than replacing a diseased or defective native valve with a mechanical or animal tissue–derived artificial valve, a tissue-engineered valve would be a living organ, able to respond to growth and ...

A Comparative Study on Early‐Stage Icing Evaluation Techniques for Passive Ice Protection Systems

Advanced Materials Interfaces, EarlyView.
This study addresses the lack of standardized methodologies for evaluating the early‐stage icing performance of passive ice protection systems. A unified experimental protocol is proposed and applied to representative hydrophilic and hydrophobic surfaces under controlled conditions.

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps

Advanced Materials Technologies, EarlyView.
Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

A simplified approach to managing a complex infected left ventricular pseudoaneurysm

Journal of Cardiothoracic Surgery
Background Left ventricular pseudoaneurysm (LVP) is a rare but life-threatening condition resulting from acute myocardial infarction, trauma, bacterial infection, or previous cardiac operations. Diagnosis can be challenging as LVPs remain asymptomatic or

Modified pseudo-elastic approach for modelling cyclic response of biological heart valves [PDF]

, 2016
A modified pseudo-elastic approach is proposed to model cyclic response on biological heart valves. The model takes into account hysteretic effects, in combination with hyperelastic anisotropic behaviour of valve leaflets, allowing reproduction of ...

Numerical comparison of the closing dynamics of a new trileaflet and a bileaflet mechanical aortic heart valve [PDF]

[[abstract]]The closing velocity of the leaflets of mechanical heart valves is excessively rapid and can cause the cavitation phenomenon. Cavitation bubbles collapse and produce high pressure which then damages red blood cells and platelets.

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Speaking from the heart: a mathematical point of view [PDF]

, 2019
The mechanics associated with a living entity dictates its ability to survive or perish. Similarly, heart valve function relies on its mechanical properties and structural integrity. A compromise in these leads to diseased valve states.
