A new mathematical approach to understanding zeolites

Zeolites are a class of natural or manufactured minerals with a sponge-like structure, riddled with tiny pores that make them useful as catalysts or ultrafine filters. But of the millions of zeolite compositions that are ...

Scientists produce high-strength plaster entirely from waste

About 5 tons of phosphogypsum is generated per ton of phosphoric acid production, and worldwide, phosphogypsum generation is estimated to be around 100 to 280 MT per year. Globally, 15 percent is recycled as building materials, ...

Scientists discover why silver clusters emit light

Clusters of silver atoms captured in zeolites, a porous material with small channels and voids, have remarkable light-emitting properties. They can be used for more efficient lighting applications as a substitute for LED ...

Long-lived catalytic converter reduces diesel emissions

Diesel vehicles today emit fewer pollutants than older vehicles, thanks to a zeolite catalytic converter that was invented around 10 years ago. Although many groups have investigated this catalyst since then, it was still ...

Zeolite catalysts pave the road to decentral chemical processes

Fuel from waste? It is possible. But hitherto, converting organic waste to fuel has not been economically viable. Excessively high temperatures and too much energy are required. Using a novel catalyst concept, researchers ...

Scientists change properties of zeolites to improve hemodialysis

Scientists of Tomsk State University are working on changing physicochemical properties of zeolites using thermal and mechanical treatment. Based on the results of this research, scientists will be able to create a new material ...

How to heal broken bonds, catalyst style

While popular catalysts called zeolites could help turn paper manufacturing waste and other biomass into fuel, the catalyst crumbles after just two days in hot water. And that's a problem because hot water is nearly ubiquitous ...

Hydroxyl radicals speed up zeolite formation

(Phys.org)—Zeolite is a Greek word that literally means a boiling stone. They are porous materials used as adsorbents, catalysts, and as ion-exchangers, and used for water filtration, detergents, and air separation, among ...
