Welcome to one of our guest columns, where active researchers can share their views on topics relevant to materials science. Professor Geoffrey Ozin from the University of Toronto tells us what he thinks about nanoscale silicon and its future. One thing that has...
Results for "sensors"
The Cheap Approach: Manipulating Polymer Nanofibers with Inexpensive Salts
Optimum operational parameters have been obtained for fabricating electrospun PVA fibers.
Cilia Revolution
University of Southern Mississippi scientists imitated Mother Nature by developing a new, skinny-molecule-based material that resembles cilia, the tiny, hair-like structures through which organisms derive smell, vision, hearing and fluid flow.
Edible Electronics: Purely Biocompatible Electrical Devices
Scientists from the University of Linz engage in developing electronics that can simply be thrown onto the compost heap or, if in a pinch, could even be eaten!
Piezotronic Logic Gates Take the Strain
US scientists have developed the first examples of logic gates (NAND, NOR and XOR gates) that can be switched simply by bending the substrate.
Porous silicon nanoneedles for barcodes and other applications
Researchers at the University of Texas have fabricated biodegradable, nanobarcodes of silicon. The porosity of the silicon structures enables their applications in bioengineering, energy storage, and drug delivery systems.
The Good Nano Stuff – Where Is It Going?
Professor Geoffrey Ozin shares his views on the current state of nanoscience, in particular the future of the promising nanomaterials: Where is the good nano stuff going?
Atomic Switches with Larger Gaps and Light-Dependence
Light is needed to initiate a new type of atomic switch that has gaps larger than the previously required 1 nm. A series of such wavelength-dependent devices could one day be used for image recognition.
Magnetic Micromachines
Chinese researchers have used lasers to made tiny springs and turbines out of a polymerized ferrofluid, which could be used in micro- or nanomachines.
Brushes Grown on Brushes
How to make one layer of polymer brushes on top of another layer by using a simple chemical initiator method…
