Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Grain boundary sliding as a deformation mechanism during creep

open access: yes, 1970
A model for grain boundary sliding is developed in which sliding occurs by the movement of dislocations along, or adjacent to, the boundary by a combination of climb and glide.

Upscaling the Fabrication of Rod‐Shaped Microgels: A Microfluidic Method Combining Step‐Emulsification With Consecutive Droplet Confinement in Parallelized Microchannels

open access: yesAdvanced Materials, EarlyView.
A microfluidic method is presented which enables parallelized fabrication of rod‐shaped microgels, based on step‐emulsification (SE) droplet generation and subsequent droplet distribution and confinement, combined in a single device. Microgel rods are fabricated in parallel at different flow rates based on two light‐mediated crosslinking chemistries ...

Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

open access: yesAdvanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Twin spacing and grain size dependent tensile deformation mechanism of a nano-ploycrystalline Ni-based alloy

open access: yesJournal of Materials Research and Technology
It is easy to form twins in Ni-based wrought superalloys with low stacking fault energy, but the effect of grain size and twin spacing on mechanical properties in nano-ploycrystalline Ni-based alloys is rarely studied. Based on the composition of a novel

Plastic deformation of dense nanocrystalline yttrium oxide at elevated temperatures [PDF]

open access: yes, 2012
Nanocrystalline yttrium oxide, Y2O3 with 110 nm average grain size was plastically deformed between 800 ◦C and 1100 ◦C by compression at different strain rates and by creep at different stresses. The onset temperature for plasticity was at 1000 ◦C. Yield
