Direct numerical simulations for non-Newtonian rheology of concentrated particle dispersions [PDF]
, 2009 The non-Newtonian behavior of a monodisperse concentrated dispersion of spherical particles was investigated using a direct numerical simulation method, that takes into account hydrodynamic interactions and thermal fluctuations accurately.

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Lattice Boltzmann model approximated with finite difference expressions
, 2017 We show that the asymptotic properties of the link-wise artificial compressibility method are not compatible with a correct approximation of fluid properties.

Advanced Robotics Research, EarlyView.A miniaturized soft optical sensor that uses thin film color tuning enables real‐time 3D shape‐sensing from a single red–green–blue (RGB) signal. When integrated into a soft robot, it enables closed‐loop control and autonomous navigation in a phantom lung environment without the need for onboard electronics, achieving sub‐millimeter accuracy through ...

Hydrodynamic Model for Conductivity in Graphene [PDF]
, 2013 Based on the recently developed picture of an electronic ideal relativistic fluid at the Dirac point, we present an analytical model for the conductivity in graphene that is able to describe the linear dependence on the carrier density and the existence ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation
Advanced Science, EarlyView.This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Small-scale dynamos in simulations of stratified turbulent convection
, 2018 Small-scale dynamo action is often held responsible for the generation of quiet-Sun magnetic fields. We aim to determine the excitation conditions and saturation level of small-scale dynamos in non-rotating turbulent convection at low magnetic Prandtl ...

Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots
Advanced Science, EarlyView.Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Melt Viscosity of the Soft Magnetic Nanocrystalline Fe72.5Cu1Nb2Mo1.5Si14B9 Alloy
EPJ Web of Conferences, 2017 Temperature dependences of the kinematic viscosity of a multicomponent Fe72.5Cu1Nb2Mo1.5Si14B9 melt have been studied. A critical temperature is detected above which the activation energy of the melt’ viscous flow changes.
