A stand-alone solar farm in Crete that integrates graphene perovskite solar panels

Posted by in categories: solar power, sustainability

Perovskites, mineral materials composed of calcium titanate, have been found to be valuable for the fabrication of high-performance solar cells. While teams of scientists and engineers worldwide have been developing and testing perovskite solar cells in laboratory settings, large-scale outdoor evaluations of these cells are still lacking.

Researchers at University of Rome Tor Vergata, the Hellenic Mediterranean University in Crete, BeDimensional S.p. A., Great Cell, the Italian Institute of Technology (IIT) and University of Siena have recently manufactured large-area solar panels engineered using two-dimensional (2D) materials. They then successfully integrated 9 of these solar panels into a stand-alone , located on the Greek island of Crete. This team’s findings, presented in a paper published in Nature Energy, could facilitate and inform the future large-scale implementation of perovskite .

“Our recent paper highlights our joint research efforts for the last 5 years in the upscaling of perovskite PVs, starting from lab cells to modules, panels and finally to a solar farm infrastructure,” Francesco Bonaccorso, one of the researchers who carried out the study, told to Tech Xplore. “This project was specifically developed in the context of the European Graphene Flagship initiative, which established a close collaboration between University Tor Vergata, BeDimensional S.p. A., GreatCell and Hellenic Mediterranean University, having both complementary and widely different skillsets.”

Boosting Michigan’s Energy Future with Regional Transmission Upgrades

Posted by in categories: energy, futurism

The regional entity overseeing much of the electric power grid in the Midwest — the Midcontinent Independent System Operator (MISO) — approved a set of major new transmission system upgrades that will bring billions of dollars in benefits to the region while better enabling states and utilities to pursue transitions to clean energy.

See here for my colleague Sam Gomberg’s excellent post explaining the background and details on what is known as “Tranche 1” of MISO’s long range transmission planning process. This much-needed set of 18 projects will improve electricity reliability, address overloaded wires, and help unlock more lower-cost wind and solar power to replace costly, polluting fossil fuel plants in Michigan and many other states in the Midwest (including Illinois and Minnesota).

A “Nano-Robot” Built Entirely from DNA to Explore Cell Processes

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye… You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier[1]. This highly innovative “nano-robot” should enable closer study of the mechanical forces applied at microscopic levels, which are crucial for many biological and pathological processes. It is described in a new study published in Nature Communications.

Our cells are subject to mechanical forces exerted on a microscopic scale, triggering biological signals essential to many cell processes involved in the normal functioning of our body or in the development of diseases.

For example, the feeling of touch is partly conditional on the application of mechanical forces on specific cell receptors (the discovery of which was this year rewarded by the Nobel Prize in Physiology or Medicine).
