A common misconception is that the irradiation of solids with energetic electrons and ions
has exclusively detrimental effects on the properties of target materials. In addition to the …

Defects in graphene alter its electrical, chemical, magnetic and mechanical properties. The
intentional creation of defects in graphene offers a means for engineering its properties …

The understanding of crack formation due to applied stress is key to predicting the ultimate
mechanical behavior of many solids. Here we present experimental and theoretical studies …

The atomic structure of a material influences its electronic, chemical, magnetic and
mechanical properties. Characterising carbon nanomaterials, such as fullerenes, nanotubes …

Grain boundary (GB) migration in polycrystalline solids is a materials science manifestation
of survival of the fittest, with adjacent grains competing to add atoms to their outer surfaces at …

A major revolution for electron microscopy in the past decade is the introduction of
aberration correction, which enables one to increase both the spatial resolution and the …

The structural transformation of various carbon nanomaterials, such as fullerene, carbon
nanotube (CNT), and graphene, has been extensively studied both experimentally and …

By combining ab initio simulations with state-of-the-art electron microscopy and electron
energy loss spectroscopy, we study the mechanism of electron beam damage in nitrogen …

We show that by operating a scanning transmission electron microscope (STEM) with a 0.1
nm 300 kV electron beam, one can sculpt free-standing monolayer graphene with close-to …

The focused electron beam of an aberration-corrected scanning transmission electron
microscope is used to create individual vacancies in predefined positions of carbon …
