Researchers aim to treat deep-seated tumors, such as those found in pancreatic cancer, by using a flower-shaped magnetic nanoparticle capable of reaching deeper within the human body than currently available methods.
Researchers have taken a step closer to producing solar fuel using artificial photosynthesis. In a new study, they have successfully tracked the electrons' rapid transit through a light-converting molecule.
Scientists explored friction at the microscopic level. They discovered that the force generating friction is much stronger than previously thought. The discovery is an important step toward understanding the physics of the cellular and molecular world and designing the next generation of microscopic and nanotechnologies.
Physicists have shown for the first time that electrons in graphene can be moved along a predefined path. This movement occurs entirely without loss and could provide a basis for numerous applications in the field of electronics.
Researchers have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their method relies on measuring characteristic microwaves emanating from the vortices. Knowledge about these signals could be used for constructing extremely small components for novel memory technology or wireless data transmission.
Based on OLED technology and implemented by means of a printing machine, this method developed by VTT Technical Research Centre of Finland Ltd provides an opportunity to create patterned and flexible light-emitting surfaces on advertising displays, info signs and lighting fixtures, for instance. The method also enables transparent smart surfaces to be attached to window panels or packaging.
For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties.
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.
What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.
A new simple tool developed by nanoengineers, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field.
Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.
