A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical Nature Methods, can be of value to both DNA nanotechnology and the development of drugs consisting of DNA fragments.
In a new study, researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice.
Starting in October 2013, the Collaborative Research Center will receive grants totaling approximately EUR 11 million over four years to develop a nanoparticle-based cancer therapy to combat melanoma as an immunogenic tumor model.
It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating 3D fractal 'building' is formed on the micro- and nanoscale.
A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists have found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased.
By engineering a semiconducting material at the level of its individual atoms, Pierre Ferdinand P. Poudeu, assistant professor of material science and engineering, has boosted its ability to convert heat into power by 200 percent and its electrical conductivity by 43 percent. That's an important combination. Improving both of these figures at the same time is a major challenge for researchers working in the field.
