Demo 03-05 Surface Dependence of Friction

open access: yes, 2001
This demonstration illustrates that the frictional force between different surfaces is very different. Four identical brass blocks are placed on strips of four different materials, and one end of the device is raised, as indicated in Figure 1, until ...

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 ...

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

open access: yesAdvanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

The coefficient of friction of individual potatoes and various handling materials - Short communication

open access: yesResearch in Agricultural Engineering, 2012
The dynamic coefficient of friction of single potatoes was determined on mild steel, rubber and plastic, for tubers in each of four conditions: dry and dirty, wet and dirty, clean and wet and clean and dry.
