A new 'solder' for laser welding of tissue during surgical operations has the potential to produce stronger seals and expand use of this alternative to conventional sutures and stapling in intestinal surgery, scientists are reporting.
Researchers have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer goods, and for medical and environmental applications.
Researchers have introduced a new approach to the separation of organic compounds. In their process, a 'host compound' recognizes the desired 'guest molecules', not only in solution, but also when the host and mixtures of competitive guest are milled together in the solid state.
The University of Manchester has announced the appointment of a world-leading academic, who is playing a pivotal role in nanomedicine - a growing field with potential to benefit patients suffering from neurodegenerative disease and cancer.
Physicists at ETH Zurich have demonstrated one of the quintessential effects of quantum optics - known as the Hong-Ou-Mandel effect - with microwaves, whose frequency is 100000 times lower than that of visible light. The experiment takes quantum optics into a new frequency regime and could eventually lead to new technological applications.
Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf together with colleagues from the Paul Scherrer Institute within the scope of an international cooperation.
Seeing the fine-scale properties of materials relevant to nanotechnology is a prominent challenge that currently can be met only under ideal conditions. Coherent X-ray imaging promises to greatly expand the range of materials and environments in which these important properties can be observed.
Researchers from Ulsan National Institute of Science and Technology (UNIST) demonstrated high-performance polymer solar cells (PSCs) with power conversion efficiency of 8.92% which is the highest values reported to date for plasmonic PSCs using metal nanoparticles.
