New microscopy technique improves imaging at the atomic scale
(Phys.org) —When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images – and those movements are virtually impossible to prevent. Now microscopy ...
Study suggests ways to improve common furniture fire test
The bench-scale test widely used to evaluate whether a burning cigarette will ignite upholstered furniture may underestimate the tendency of component materials to smolder when these materials are used in ...
