Digital 3D models of historic buildings or cultural heritage objects are useful for preservation. Not only can we store them permanently, but the models can supply a clear guideline for the restoration process. 3D models also provide sufficient information about geometrical characteristics that may help archaeologists to inspect and classify the objects. The Bayon temple, which consists of 52 t...

Scientists have predicted that carbon’s immediate neighbors on the periodic chart, boron and nitrogen, may also form perfect nanotubes, since the advent of carbon nanotubes (CNTs) in 1991. First proposed then synthesized by researchers at UC Berkeley in the mid 1990’s, the boron nitride nanotube (BNNT) has proven very difficult to make until now. Herein we provide an update on a catalyst-free m...
