Advanced Functional Materials, EarlyView.Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Advanced Functional Materials, EarlyView.InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...

Enacted task design: tasks as written in the classroom [PDF]
, 2016 This paper presents and describes the construct of enacted task design, which considers the way tasks are “written” (designed) by teachers. Two enactments by different teachers based on the same written algebra task were analyzed and compared using the ...

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Uma relação entre a álgebra e a geometria na parábola
CQD Revista Eletrônica Paulista de Matemática, 2022 Neste trabalho trazemos uma discussão sobre a parábola, pelo prisma das funções polinomiais do 2º grau e pelo viés da geometria analítica, fazendo uma ponte entre estes dois assuntos.

Multi-objective optimization of a type of ellipse-parabola shaped superelastic flexure hinge [PDF]
Mechanical Sciences, 2016 Flexure hinges made of superelastic materials is a promising candidate to enhance the movability of compliant mechanisms. In this paper, we focus on the multi-objective optimization of a type of ellipse-parabola shaped superelastic flexure hinge.
