A high intensity and rapid light pulse directly heats the semiconducting metal-oxide thin film, allowing to achieve the optimal heating conditions without damaging the substrate.
Scientists have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes. This view into processes that take place within so-called artificial spin ice could play an important role in the development of novel high-performance computers.
Platinum is an important catalyst. But up until now, nobody know how exactly single platinum atoms behave during catalysis. Scientists could now solve the riddle, why some chemical reactions take place at temperatures at which this should not even be possible.
Combining the benefits of both fluid and solids, researchers have demonstrated various functions for their slimebots, including navigation in narrow channels much smaller than their size; object capture operations via the curl or endocytosis modes; and circuit repair and controlled switching using their own conductive properties that can even be reconfigured as self-healing strain sensors for monitoring human motion. The widely applicable working environment of these novel magnetic slime ...
Researchers introduce a new path towards superior organic thermoelectric devices: highly efficient modulation doping of highly ordered organic semiconductors under high doping concentrations.
Scientists have found a common substance that can reversibly and rapidly store and release relatively large amounts of low-grade heat without decomposing. The research could lead to more efficient reuse of industrial waste heat.
Researchers present a new concept for realizing ultrafast modulation of multi-target focal fields based on the facile combination of the time-dependent vectorial diffraction theory with the fast Fourier transform.
