Any Shape, Any Substrate Ferroelectric Materials
A new method of making ferroelectrics that uses a heated probe tip means they can be produced directly on virtually any substrate and in any shape.
Quantitative Blueprint for Better Nanomachines
The possibility to obtain work from nanomachines is a step closer to reality as scientists provide a quantitative framework describing interfacial interactions in a nanobiomolecular system.
Nanocontrol using Peptides
Small changes can have a big effect; a very small change in molecular structure can have a profound controlling effect on the size of gold nanoparticle superstructures.
Multimetallic Nanomachines: Magnetic and Chemical Power Combine
Scientists at University of California, San Diego, USA, led by Joseph Wang, have put together a multisegment nanomotor that contains components responsive to magnetic and to chemical stimuli.
