A 'hole' lot of sponge! New technique to create super-sponges is a game changer

Metal-organic frameworks (MOFs) are sponge-like organic-inorganic hybrid materials and have a variety of uses due to their ultra-high porosity, or the ratio of pores or air pockets to the solid material. Through a technique called post-synthetic modification, researchers were able to enhance and modify the function of these materials for specific purposes.

Recent research results have shown that it is possible to use a novel technique to selectively produce methane, carbon monoxide or formic acid from carbon dioxide and water.

A metal organic framework material opens the door for deeper than ever biological imaging

Scientists established an approach for the creation of a metal-organic framework material that provides new perspectives for the sensitization of near-infrared luminescent lanthanide ions, including unprecedented possibilities of imaging deeper in tissues for more comprehensive studies of biological systems with light.

An unexpected property of nanometer-scale antimony crystals - the spontaneous formation of hollow structures - could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.
