A workshop organized last year by the PETA International Science Consortium Ltd has resulted in an article that describes aerosol generation and exposure tools that can be used to predict toxicity in human lungs following inhalation of nanomaterials.
Several international scientists from over 30 universities and institutes teamed to investigate to what extent quantum simulations of material properties agree when they are performed by different researchers and with different software.
Researchers demonstrate that rectification ratios of greater than 250 at biases of 0.5 V are achievable at the two-molecule limit for donor-acceptor bilayers of pentacene on C60 on Cu using scanning tunneling spectroscopy and microscopy.
Researchers were able for the first time to observe the defects as these formed during deposition and under what conditions they self-healed by using in-situ X-ray diffraction and fluorescence analysis.
With the aid of terahertz radiation, Munich physicists have developed a method for generating and controlling ultrashort electron pulses. With further improvements, this technique should be capable of capturing even electrons in motion.
In a proof-of-principle experiment, researchers have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, the weird quantum interactions of electrons in materials.
Light propagating in a layer of scattering nanoparticles, shows the principle of diffusion. The deeper light is penetrating into the layer, the lower the energy density. Scientists managed to turn this falling diffusion curve into a rising one, by manipulating the incident light.
