True to Moore’s Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon — the backbone of modern transistors — loses its electrical properties once devices made from this material dip below a certain size.

The Sun’s rotation produces changes in its magnetic field, which flips completely every 11 years or so, triggering a phase of intense activity.

Perovskite solar cells (PSCs) are promising solar technologies. Although low-cost wet processing has shown advantages in small-area PSC fabrication, the preparation of uniform charge transport layers with thickness of several nanometers from solution for meter-sized large area products is still challenging.

A group of scientists at the Hefei Institutes of Physical Sciences of the Chinese Academy of Sciences has developed new p-type (positive hole) near infrared (NIR) transparent conducting (TC) films with ultra-high conductivity, unveiling a new transparent conducting material (Advanced Optical Materials, « p-Type Near-Infrared Transparent Delafossite Thin Films with Ultrahigh Conductivity »).

The Rice University lab of chemist James Tour introduced a technique to tune the surface of anodes for batteries by simply brushing powders into them. The powder adheres to the anode and becomes a thin, lithiated coating that effectively prevents the formation of damaging dendrites.

Think of a computer chip that bends, rather than breaks. That’s the potential of a new study by scientists at Rice University and Los Alamos National Laboratory (Nature Nanotechnology, « Wafer-scale monodomain films of spontaneously aligned single-walled carbon nanotubes »).

For several years, CODEX INTERNATIONAL has been the European representative of LUMTEC Cie, a world leader in the manufacture of organic chemicals, such as OLED materials, developing innovative organic optoelectronic materials for the OLED, OPV and OTFT markets.

Scientists at Oak Ridge National Laboratory and the University of Nebraska have developed an easier way to generate electrons for nanoscale imaging and sensing, providing a useful new tool for material science, bioimaging and fundamental quantum research.

To perform a risk assessment of nanomaterials in the environment, information on the exposure, i.e. the amounts that are present in the environment, is essential. In contrast to many other known pollutants, the concentrations of nanomaterials in environmental systems cannot be measured directly. In this situation, exposure modelling is a solution to estimate the environmental exposure with synthetic nanomaterials.
