Planet-forming disks around very low-mass stars are different
Jun 06, 2024 (Nanowerk News) Planets form in disks of gas and dust, orbiting young stars. The MIRI Mid-INfrared Disk Survey (MINDS), led by Thomas Henning from the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, aims to establish a representative disk sample. By exploring their chemistry and physical...
Calcium oxide’s quantum secret: nearly noiseless qubits
Jun 06, 2024 (Nanowerk News) Calcium oxide is a cheap, chalky chemical compound commonly used in the manufacturing of cement, plaster, paper, and steel. But the material may soon have a more high-tech application. UChicago Pritzker School of Molecular Engineering researchers and their collaborator in Sweden have used theoretical and...
