Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Techno-Economic Design of Flue Gas Condensers for Medium-Scale Biomass Combustion Plants: Impact of Heat Demand and Return Temperature Variations

open access: yesEnergies, 2019
Despite their obvious benefit in terms of energy efficiency and their potential benefit on pollutant emissions, Flue Gas Condensers (FGCs) are still not widely spread in biomass combustion plants.

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Clinical Outcomes and Return to Sport in Competitive Athletes Undergoing Iliopsoas Fractional Lengthening as a Part of Hip Arthroscopy - Minimum Two-Year Follow-Up

open access: yesOrthopaedic Journal of Sports Medicine, 2017
Objectives: The iliopsoas is a hip flexor and stabilizer that may be associated with internal snapping. Although flexion and stability are important in competitive athletes, painful internal snapping may be debilitating and may necessitate arthroscopic ...

Computational modeling of time-dependent behavior of thermoset polymers [PDF]

open access: yes, 2020
Mezi materiály, které se začínají v dnešní době více používat patří reaktoplasty. V odvětvích jako je automobilový nebo letecký průmysl jsou reaktoplasty dostatečně vytvrzené, naopak ve stavebnictví jsou často používané vytvrzené nedostatečně, což ...

A Non‐Reciprocal Architected Porous Medium

open access: yesAdvanced 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.

Annuity markets in Chile : competition, regulation - and myopia ? [PDF]

open access: yes
The author studies annuity rates in Chile and relates them with industry competition. He finds (1) that annuity insurance companies paying higher broker commissions paid lower annuity rates; and (2) a structural break of the long-run elasticity of ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).
