Researchers identify cause of surface barriers of metal-organic frameworks: Relevant to gas storage

Posted: 31 Jul 2014 11:56 AM PDT

Metal-organic frameworks (MOFs) can take up gases similar to a sponge that soaks up liquids. Hence, these highly porous materials are suited for storing hydrogen or greenhouse gases. However, loading of many MOFs is inhibited by barriers. Scientists now report that the barriers are caused by corrosion of the MOF surface. This can be prevented by water-free synthesis and storing strategies.

Low-grade nonwoven cotton picks up 50 times own weight of oil

Researchers have developed a novel method, based on energy-selective neutron imaging for visualization of crystalline phase distributions within the bulk of metallic samples.

Reinventing biology labs by turning smartphones into microscopes

Posted: 29 Jul 2014 06:26 AM PDT

With nothing more than a smartphone and less than $10 of trinkets and hardware supplies, students can build their own microscopes. The DIY microscopes can magnify samples up to 175 times with a single laser pointer lens, or nearly 400 times when stacking two lenses.
