Scientists have discovered an elegant way of manipulating light using a 'synthetic' Lorentz force - which in nature is responsible for many fascinating phenomena including the Aurora Borealis. • Email to a friend • An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable - a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining four cutting-edge methods finds that the modest material boasts fantastic and surprising quantum properties. • Email to a friend • Researchers describe a technique for using LEGO-like elements at the scale of a few billionths of a meter. Further, they are able to cajole these design elements to self-assemble, with each LEGO piece identifying its proper mate and linking up in a precise sequence to complete the desired nanostructure. • Email to a friend • A new study shows that RNA nanoparticles have elastic and rubbery properties that help explain why these particles target tumors so efficiently and why they possess lower toxicity in animal studies. • Email to a friend • Researchers solve the mystery of observed quasi-crystalline structures with the help of state-of-the-art electron microscopy. • Email to a friend • A closer look at gold nanoparticles, which were welded together by laser excitation, revealed interesting insights on the atomic structure and how it influences the physical properties of the system. • Email to a friend • New study details the molecular-level design of materials that enable clean and sustainable water evaporation energy to be harvested and efficiently converted into motion with the potential to power future mechanical devices and machines. • Email to a friend • Scientists have developed an easier way to generate electrons for nanoscale imaging and sensing, providing a useful new tool for material science, bioimaging and fundamental quantum research. • Email to a friend • Scientists succeeded in having several different nanocapsules work in tandem to amplify a natural signaling cascade and influence cell behavior. • Email to a friend • Material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They can become a safe alternative to the usual antibiotics in implantology since they do not have typical negative side effects. • Email to a friend • Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers have demonstrated that DNA damage may also occur far away from the point of incidence of the radiation. • Email to a friend • Researchers have developed highly thermally conductive polyimide film with superior flexibility and electrical insulation. • Email to a friend • Researchers have provided an example of on-demand control of quantum phenomena to design the quantum materials. By state-of-the-art quantum mechanical simulations, they find that a two-dimensional transition-metal ditelluride, MoTe2, can realize a structural phase transition from the semiconducting phase to the topological phase triggered by photoexcitation of carriers alone. The sub-picosecond phase transition can be controlled by varying the laser wavelength. The research is inspired by the classical phase transition theory proposed by Lev Davidovich Landau and Rudolf Ernst Peierls. • Email to a friend • Scientists have discovered the possibility to prepare one-atom thin platinum for use as a chemical sensor. • Email to a friend • |
