Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

Advanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

A Miniaturized Autonomous Thermomagnetic Generator

Advanced Functional Materials, EarlyView.
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

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

Advanced 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 ...

Fast Hydrogel Micro‐Actuators Driven by Electric Fields

Advanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

Analysis of Cantilever Beam Deflection under Uniformly Distributed Load using Artificial Neural Networks

MATEC Web of Conferences, 2019
In this study the deflection of a cantilever beam was simulated under the action of uniformly distributed load. The large deflection of the cantilever beam causes the non-linear behavior of beam.
