A light touch for membrane selectivit

Aug 23, 2020

Membranes that change their pore size in response to external stimuli, such as pH, heat and light, are set to transform separation science and technology. Such smart membranes developed by KAUST researchers display tunable pore size, which means they can selectively separate compounds according to their size when exposed to different light wavelengths.

Space invaders as MOFs act as liquids

Aug 11, 2020

Innovative materials called metal organic frameworks (MOFs) could become much more versatile following research that shows that they can be manipulated as liquids.

New spin brings rapid rescue from oil spills

Jul 23, 2020

An intrinsically porous polymer with a very high internal surface area could be an ideal material for soaking up spilled oil. Researchers from KAUST have identified a polymer that can be formed into robust, reusable mats to rapidly adsorb spilled oil, fuel or organic solvents from the surface of fresh or salt water.

Early warning sensor sniffs out cities' harmful gas

May 11, 2020

The design for an electronic sensor that sounds the alarm if toxic industrial and vehicle-exhaust gases exceed safe levels could lead to cleaner air in many cities. KAUST researchers have developed a small, low-cost device that senses nitrogen dioxide (NO2); it could be deployed in potential hotspots around cities, alerting authorities if levels of the harmful gas start to spike.

Stabilizing ligands make nanoclusters brighter

Nov 19, 2019

Metal nanoclusters that bear tunable surface ligands could help develop next-generation imaging and photocatalytic approaches, suggests work by KAUST researchers.

Waste plastic converted into filtration membranes

Oct 22, 2019

In a world that seems to be drowning in plastic bottles, recycling this waste into useful materials would help to reduce its environmental impact. KAUST researchers have now invented a way to turn plastic bottles into porous membranes that could be used as molecular filters in the chemical industry.

Imperfection is OK for better MOFs

Jun 26, 2019

Perfect crystals are not necessarily the most useful. Defects in the ordered crystalline structure of metal-organic frameworks (MOFs) could tailor these versatile materials for specific applications. KAUST researchers have already developed a pioneering method to image the defects using transmission electron microscopy. They now report that creating specific defects, visualizing them, and investigating their chemical effects takes the exploration of MOFs to new levels of detail and control.

KAUST researchers have tailored the structure of graphene-oxide layers to mimic the hourglass shape of these biological channels, creating ultrathin membranes to rapidly separate chemical mixtures.

MOFs can sense and sort troublesome gases

Apr 08, 2019

From astronauts and submariners to miners and rescue workers, people who operate in small enclosed spaces need good air quality to work safely and effectively. Electronic sensors now developed by a KAUST team can simultaneously detect at least three critical parameters that are important to monitor to ensure human comfort and safety.

Cleaning up with cellulose

Mar 10, 2019

Environmentally friendly method for making membranes adds greener options for processing industrial waste. Selectively permeable membranes made from renewable plant-based materials could significantly improve the environmental credentials of the chemical industry. A KAUST team has tested the viability of cellulose membranes to show they can effectively clean wastewater.

Driving water down nanohighways

Mar 03, 2019

Self-assembled channels in a polymer membrane could greatly enhance extraction of water from gases. Removing water vapor from air and other gas mixtures, which is crucial for many industrial processes and air conditioning, could become cheaper and more effective through polymer membrane technology now developed at KAUST.
