Hollow carbon nanospheres (HCNSs) were fabricated by annealing the Cu–C core–shell nanoparticles at 1250 °C in vacuum. The as-obtained HCNSs have ultrathin shell of 1–3 nm in thickness, small size of ...

Thanks to its airplane-shaped folding, the paper plane is statically stable in the vacuum-like upper reaches of space. It ...

Atomic layer deposition is demonstrated to be greatly suitable to tune the pore size of ink-bottle mesopores at the atomic level. This is confirmed by quantitative electron tomography, which enables a ...
