MOF based motorboat | Chemistry World - Researchers from the US and Japan have devised a new type of molecular motor capable of propelling itself across a liquid surface. The move marks another step along the road towards mimicking motile life forms found in nature, such as bacteria, in the quest for autonomous microscopic machines.(10.1038/nmat3461)

MOFs ready to gulp down radioactive iodine gas - A porous material that can hold up to one and a quarter times its own weight of molecular iodine could help to mop up gaseous radioactive isotopes of the element. A US-based team has shown that the material could be useful for trapping the radioactive iodine released during nuclear fuel reprocessing, and also help to prevent inadvertent environmental release of the gas, as occurred earlier this year at Japan's Fukushima nuclear power plants. The material in question is a metal-organic framework (MOF), a highly porous structure with a huge internal surface area ideal for adsorbing large volumes of gas. Tina Nenoff at Sandia National Laboratories in Albuquerque, New Mexico, and her colleagues have shown that a MOF known as zeolitic imidazolate framework-8 (ZIF-8) can be used to permanently capture large volumes of iodine.
