Nanotechnology Now Home > Press > Removing the lead hazard from perovskite solar cells A transparent phosphate crystal, which incorporated into solar cells, can instantaneously immobilize the lead in case of failure and block its leaching out from the device. CREDIT Endre Horváth (EPFL) Abstract: The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells, says Professor László Forró at EPFL s School of Basic Sciences. But their central element is lead, which is a poison; if the solar panel fails, it can wash out into the soil, get into the food chain, and cause serious diseases. ....
Our NanoNews Digest Sponsors Home > Press > Putting functional proteins in their place: Using DNA-based assembly, scientists developed a method for creating designed and biologically active 2-D and 3-D protein arrays, which show promise for applications in structural biology, biomaterials, nanomedicine, and biocatalysis An illustration showing the approach for assembling biologically functional proteins into ordered 2D and 3D arrays through programmable octahedral-shaped DNA frameworks. These frameworks can host and control the placement of the proteins internally for example, at the center (1) or off-center (2) and be encoded with specific sequences externally (color coding scheme) to create desired 2-D and 3-D lattices. For example, red only connects to red, blue to blue, and so on. The team demonstrated the preserved biological activity of ferritin lattices by adding a compound (ascorbate) that induced the release of iron irons forming the ferritin core. ....
Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Pushing the boundaries of colloidal quantum dots by making their sizes equal: Scientists demonstrate the relationship between optoelectronic performance and size uniformity in perovskite colloidal quantum dots Younghoon kim, Ph.D. (Left) and Prof. Jongmin Choi(Right), DGIST. CREDIT DGIST Abstract: Quantum dots (QDs) are semiconductor particles only a few nanometers across that, thanks to their small size, exhibit peculiar optical and electronic properties due to quantum mechanics. With existing and foreseen applications in screens, lighting, lasers, and energy harvesting, research in quantum dots has been steadily progressing. In particular, colloidal QDs (CQDs) have been in the nanotechnology spotlight for over a decade. ....
