Computer scientists are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin. By operating these touch input stickers, users can use their own body to control mobile devices.
Solar cells made out of lead sulfide quantum dots could eventually offer a cheaper, more flexible alternative to ones made using silicon, but they are currently much less efficient. However, altering the chemical composition of quantum-dot solar cells offers a way of tuning them to reach higher efficiencies.
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.
