Strategies to generate larger pores in metal-organic frameworks

Due to the advantages such as large specific surface area, adjustable pore size and tunable functionality, metal-organic frameworks (MOFs) have shown great application potential in the fields of gas adsorption and separation, catalysis, sensing and biomedicine. However, most metal-organic frameworks have pore sizes below 2 nm and are typical microporous structures, which limits pore structure and hinders mass transfer within the framework. In order to overcome this limitation, researchers introduced mesopores or macropores in microporous MOFs to generate multi-level pore structure through various strategies.

Seismic study reveals key reason why Patagonia is rising as glaciers melt

The icefields that stretch for hundreds of miles atop the Andes mountain range in Chile and Argentina are melting at some of the fastest rates on the planet. The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5

New method to detect and visualize sperm cells recovered from forensic evidence

One of the most valuable forms of forensic evidence in cases of male-perpetrated sexual assault is the presence of semen, either in the form of stains left behind on items or on swabs collected from victims after an offense. To confirm that semen is present, suspected stains are examined under a microscope to see if any sperm cells are visible. from Phys.org - latest science and technology news stories https://ift.tt/2XBwacB
