A fast, efficient, selective membrane for purifying saltwater
Water scarcity is a growing problem around the world. Desalination of seawater is an established method to produce drinkable water but comes with huge energy costs. For the first time, researchers use fluorine-based nanostructures to successfully filter salt from water. Compared to current ...
An international team publishes a system that generates this universal fuel with almost no waste
An international team involving the Institute of Chemical Technology (ITQ), a joint center of the Spanish National Research Council (CSIC) and the Polytechnic University of Valencia (UPV), has developed a new electrified reactor to obtain hydrogen in a more sustainable and energy-efficient way. ...
Licensing the technology for a start-up
Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. A research team led by Chris Arges, Penn State ...
Molecular sieve membrane-based separation technology, featuredwith low energy consumption and small carbon footprint, has attracted much attention in gas separation. Metal-organic frameworks (MOFs) arepromising in gas separation membranesdue to their diversified structures, high porosity and ...
“Materials like this with selective permeability are in high demand in industry”
Scientists have long tried to use graphene, which is composed of carbon, as a kind of sieve. But this material doesn’t have any pores. Now, a team has found an alternative material which comes with pores from the outset. Researchers from Bielefeld, Bochum and Yale have succeeded in producing a ...
Carbon capture advance could bring environmentally friendly fuel cells closer to market
University of Delaware engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen. It is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to ...
Waste materials are used to create an environmentally friendly filtration system for industrial applications.
Shrimp shells, plant extracts and recycled plastic have helped KAUST researchers to build a sustainable thin-film composite membrane that could replace conventional membranes whose environmental toll is greater. Thin-film composite membranes are widely used in applications such as wastewater ...
Sepion Technologies is pursuing innovative new lithium battery technologies and recently secured Series A funding
For America to move fully away from fossil fuels and to a more sustainable energy economy, batteries are the key ingredient. For both electric vehicles and the power grid, new battery technologies will transform the energy equation behind how we live and how we move. As part of this effort, the ...
Ion separation using membrane separation technologyis of greatimportance inthefieldsincludingenergy conversion and storage, environmental detection and resource reuse. Membranes with sub-2-nanometer channels have high ion transport rates but they fail to sieve different ions effectively due ...
Metal organic framework membranes that selectively separate hydrocarbons set the stage for more sustainable petrochemical processes
An electrochemical approach developed at KAUST produces molecular-sieving membranes that could enable a cheap energy-efficient separation of light hydrocarbons, such as olefins and paraffins. This separation, critical for the petrochemical industry, usually relies on extremely energy-intensive ...
