科学家合成出六边形的盐  

While it probably won't make it to your dining table
a new scientific achievement might be able to help in everything from radar equipment to electric cars: scientists have been able to form salt
aka sodium chloride (NaCl)
in a hexagonal shape.
This is work done at the smallest of scales
with researchers able to get a thin film of hexagonal salt to form on top of a layer of diamond
due to the chemical interaction of both film and diamond substrate – something the team actually predicted would happen in advance through simulations.
It's the latest in a series of discoveries where scientists have been able to synthesise 2D materials with unusual crystal structures
and it's partly this self-imposed restriction to o dimensions that is enabling new and exotic structures to be formed.
这是科学家利用不寻常的晶体结构合成二维材料的最新发现，在一定程度上，这种对二维空间的自我限制促成了新的奇异结构的形成。
"Initially we decided to perform only a putational study of the formation of new 2D structures on different substrates
driven by the hypothesis that if a substrate interacts strongly with the NaCl thin film
one can expect major changes in the structure of the thin film
" says material scientist Kseniya Tikhomirova from the Skolkovo Institute of Science and Technology (Skoltech) in Russia.
"Indeed
we obtained very interesting results and predicted the formation of a hexagonal NaCl film on the diamond substrate
and decided to perform experiments. Thanks to our colleagues who performed the experiments
we synthesised this hexagonal NaCl
which proves our theory."
