[Wafers] – Engineers grow ‘perfect’ atom-thin materials on industrial silicon wafers 14 novembre 2023

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.

[Plasma] – Temperature of solar flares helps understand nature of solar plasma 14 novembre 2023

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

[perovskites] – Scientists fabricate high-performance large-area perovskite submodules for solar cells 14 novembre 2023

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.

[Thin-Films] – Brushing thin films onto electrodes preserves batteries 21 septembre 2023

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.

[Thin-Films] – A low-tech, solution-based route to high-performance carbon nanotube thin films 21 septembre 2023

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”).

[Nanotechnology]- Estimating the occurrence of nanomaterials in the environment 12 septembre 2023

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.
