Researchers have developed a material suited for photovoltaics. For the first time, a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds (MOFs). The material is highly elastic and might also be used for the flexible coating of clothes and deformable components.

In a typical experiment involving biological material such as nanoscale hairs, it would usually be sufficient to use an electron microscope to create an image of the surface of the specimen. This research, however, required to look inside the ant hairs and produce a cross-section of the structure's interior. The relatively weak beam of electrons from a standard electron microscope would not be able to penetrate the surface of the sample.

Read moreStructural origin of glass transition
Scientists have demonstrated through computer simulations that the enhancement of fluctuations in a liquid's structure plays an important role as a liquid becomes a solid near the glass-transition point, a temperature below the melting point. This result increases our understanding of the origin of the glass transition and is expected to shed new light on the structure of liquids, thought until now to have been uniform and random.

Researchers have developed a 'placenta-on-a-chip' to study the inner workings of the human placenta and its role in pregnancy. The device was designed to imitate, on a micro-level, the structure and function of the placenta and model the transfer of nutrients from mother to fetus.

Using grazing incidence small angle x-ray scattering (GISAXS) and surface-enhanced Raman scattering (SERS), very small differences in the distribution of coated-nanoparticle membranes were detected and found to be responsible for their folding into tubular structures. Molecular dynamics simulations show this is related to surface molecular packing density and mobility.
