The fabrication of shape-memory hydrogel scaffolds not only requires biocompatibility, micrometer resolution, high mechanical strength, but also requires a low polymerisation threshold in high-water content environment to ...
Despite the anticounterfeiting devices attached to luxury handbags, marketable securities, and identification cards, counterfeit goods are on the rise. There is a demand for the next-generation anticounterfeiting technologies—that ...
Optical sensors can quantitatively analyze chemical and biological samples by measuring and processing the optical signals produced by the samples. Optical sensors based on infrared absorption spectroscopy can achieve high ...
The University of Michigan has successfully demonstrated the "charge separation effect," predicted over a decade ago, which has important potential for direct conversion of light to electricity without the thermodynamic losses ...
You have to look closely, but the hills are alive with the force of van der Waals.
Scientists at Paderborn University, the Technical University of Dortmund and the University of Würzburg have for the first time used laser pulses to precisely control photon echoes, which can occur when light waves superimpose ...
A single laser is shot through a microscopic comb, which splits into a rainbow of colors. It all happens in a highly controlled manner on a tiny photonic resonator, and could pave the way toward more accurate clocks, the ...
Using barcodes to label and identify everyday items is as familiar as a trip to the supermarket. Imagine shrinking those barcodes a million times, from millimeter to nanometre scale, so that they could be used inside living ...
Physicists from the University of Konstanz, Ludwig-Maximilians-Universität München (LMU Munich) and the University of Regensburg have successfully demonstrated that ultrashort electron pulses experience a quantum mechanical ...
Strain engineering usually refers to a kind of material processing technology which aims to regulate the properties of materials or optimize related devices' performance by inherent or external strain. In recent years, with ...
