Although the magnetoelectric effects - the mutual control of electric polarization by magnetic fields and magnetism by electric fields, have been intensively studied in a large number of inorganic compounds and heterostructures, they have been rarely observed in organic materials. Here we demonstrate magnetoelectric coupling in a metal-organic framework(More)
A rotary engine with rectangle pistons and cylinders is claimed to have higher mechanism efficiency for eliminating the lateral force between piston skirt and liner. Constrained by the present machining and assembly accuracy, surfaces of piston could not fit the internal surface of cylinder well which might lead to gas leakage from cylinder. A novel ring(More)
