The First Observation of a New Kind of Crystal Assembly: New Law of Togetherness

- This research was conducted by Gautam Ujjal
An exquisite natural phenomenon that polarity-induced assembly of crystals can occur was discovered. A ZnO rod has a positive and a negative polar end and in a concentric assembly, all rods grow along a single polar end, resulting in different properties. The same could be relevant to other materials too and lead to novel applications.
