Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

open access: yesAdvanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

The comparisons of computational models of pavement due to the dynamic load act

open access: yesMATEC Web of Conferences, 2017
Finite element method (FEM) is frequently used to solve current problems of the structural mechanics in engineering practice. The dynamic interaction of the two systems is one of the topics that can be solved using FEM.

Relation of Temperature Changes in Asphalt Pavements to Pavement Bearing Capacity Evaluation

open access: yesCommunications, 2007
Temperature changes in asphalt pavements have to be taken into account at the diagnostic and evaluation process of pavements bearing capacity. Theoretical calculations resulting from general theory are not suitable for the practical use.

Using Historic Pavement Performance Data to Identify and Select Sites for Asphalt Mixture Design Studies [PDF]

open access: yes, 2017
Since 1997 Arkansas asphalt mixtures have been designed using a procedure commonly known as ‘Superpave’. In a traditional Superpave mix design, the design considers only traditional volumetric parameters; however, recent advances in mix design technology

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

open access: yesAdvanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

open access: yesAdvanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

An overview of mini systematic literature on factors that influence the parents "perspective of leaving their children to / from school [PDF]

open access: yes, 2021
The first walk to school program was in 1997, with just five primary schools taking part in Hertfordshire. Walk to School Day began in the United States of America (USA). as a one-day event. The first-ever International Walk to School Day launched in
