The first spectroscopic studies of krypton-98 and krypton-100 suggest that these nuclei exist in a quantum superposition of two distorted shapes. The study also provides evidence that neutron-rich ...

Due to a phenomenon called the shape memory effect (SME), certain "memory metals" can be distorted and then brought back to their original shape by a simple temperature change. While a one-way memory ...

Looks can be deceiving, especially when it comes to nebulae. From here on Earth, the well-studied Ring Nebula looks like a fiery, slightly misshapen ring with fuzzy edges and a hole in its center. But ...

A new technique measures free-form wafer shape, write Marco Franchi, Wooptix, and Leon van Dijk, Ronald Otten, Richard Van Haren, ASML. On-product overlay (OPO) is one of the most critical parameters ...
