Since the discovery of quasicrystals, solids that mimic crystals in their long-range order but lack periodicity, scientists have sought physical properties related to their peculiar structure. Now, an international group of researchers has reported a long-range magnetic order in QCs with icosahedral symmetry that turns ferromagnetism below certain temperatures.

Researchers in Japan have found an energy-efficient way to convert the chief greenhouse gas carbon dioxide (CO2) into useful chemicals. Using the method, CO2 is transformed into structures called metal-organic frameworks (MOFs), suggesting a new and simpler route to dispose of the greenhouse gas to help tackle global warming.

The generation of alkyl radicals was achieved by direct visible-light excitation of the organoborate complex, which was designed and synthesized from “boracene,” which has a boron atom in the tetracene-like skeleton. The alkyl radicals thus obtained could be used as a carbon source for chemical reactions, enabling the synthesis of complicated/bulky organic compounds. The present study offers a new protocol for organic synthesis, which is expected to accelerate e.g. drug discovery.
