Found in space: Complex carbon-based molecules

Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons (PAHs). Since the 1980s, circumstantial evidence has indicated that these molecules are abundant in space, ...

Criteria to predict experimentally stable allotropes

(Phys.org)—A group of researchers from France, the U.K. and Florida proposes criteria to determine whether an allotrope is experimentally feasible. They use theoretical carbon allotropes, penta-graphene and Haeckelites, ...

8th century gamma ray burst irradiated the Earth, study finds

(Phys.org)—A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph ...

Red Crucifix sighting in 774 may have been supernova

(Phys.org) -- A supernova may have actually been the mysterious "Red Crucifix" in the sky that is cited in the Anglo Saxon Chronicle for the year 774. New correspondence between a university student and Nature carries interesting ...

New way of synthesizing organic chemicals mimics nature

Organic chemists have found a new way of synthesizing multiple complex organic molecules that until now have needed to be synthesized using time-consuming methods. The new strategy, which mimics natural biosynthesis methods, ...

Defect in graphene may present bouquet of possibilities

(PhysOrg.com) -- A class of decorative, flower-like defects in the nanomaterial graphene could have potentially important effects on the material's already unique electrical and mechanical properties, according to researchers ...
