Scientists have unlocked the secret to creating stable dynamic skyrmions – the nanoscale magnetic whirls that promise to meet our insatiable appetite for data storage
When scientists began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes for use in electronics or optical devices. Now they believe this technique might roll solo. Researchers now show that these cycloparaphenylenes can be made using a variety of atoms, not just those from carbon.
Physicists have devised a way to use diamonds to identify cancerous tumors before they become life threatening. Their findings reveal how a nanoscale, synthetic version of the precious gem can light up early-stage cancers in non-toxic, non-invasive Magnetic Resonance Imaging (MRI) scans.
Researchers have succeeded in building protein gates for artificial nano-vesicles that become transparent only under specific conditions. The gate responds to certain pH values, triggering a reaction and releasing active agents at the desired location.
A team of scientists has synthesized a powerful new magnetic material that could reduce the dependence of the United States and other nations on rare earth elements produced by China.
Working with a device that slightly resembles a microscopically tiny tuning fork, researchers have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error — potentially enabling the weighing of individual molecules in liquid environments.
A research group has succeeded in fabricating an atomically thin, high-temperature superconductor film with a superconducting transition temperature (Tc) of up to 60 K (-213°C). The team also established the method to control/tune the Tc.
Natural channel proteins are integrated into artificial membranes to facilitate the transport of ions and molecules. Researchers have now been able to measure the movement of these channel proteins for the first time. They move up to ten times slower than in their natural environment, namely the cell membrane. These study results may prove useful to the ongoing development of new applications such as nanoreactors and artificial organelles.
Machine parts wear, if there is friction between their metal surfaces. Lubricants and functional oils help prevent this. They attract dirt, debris and dust, and over time form lumps or become resinous. Machine parts then have to be intensively cleaned and regreased, which leads to more frequent maintenance, greater consumption of resources, polluting waste or machine breakdowns. Researchers have now developed a functional coating which lubricates without grease and protects against corrosion at the same time. It is suitable as a coating for metals and metal alloys such as steel, aluminum or magnesium.
Researchers have made the world’s smallest spirals and found they have unique optical properties that are nearly impossible to counterfeit if they were added to identity cards, currency and other objects.
