Porous Crystals Detect Nitric Oxide

Ultrasensitive detection of NO using a conductive 2D metal–organic framework

17-Dec-2024 - Detection of nitric oxide (NO) is important for monitoring air quality because the NO released in the combustion of fossil fuels contributes to acid rain and smog. In medicine, NO is an important messenger molecule and serves as a biomarker for asthma. In the journal Angewandte Chemie, a research ...

Breakthrough in capturing 'hot' CO2 from industrial exhaust

A metal-organic framework is capable of capturing CO2 at extreme temperatures

19-Nov-2024 - Industrial plants, such as those that make cement or steel, emit copious amounts of carbon dioxide, a potent greenhouse gas, but the exhaust is too hot for state-of-the-art carbon removal technology. Lots of energy and water are needed to cool the exhaust streams, a requirement that has limited ...

Argonne scientists use AI to identify new materials for carbon capture

Metal-organic framework (MOF) materials can be used in many different applications, from catalysts to energy converters

16-Feb-2024 - GenerativeAItechniques, machine learning and simulations give researchers new opportunities to identify environmentally friendly metal-organic framework materials. Carbon capture is a critical technology in reducing greenhouse gas emissions from power plants and other industrial facilities. But ...

Getting it to stick: Grabbing CO₂ out of the air

Direct air capture is hard to do - Pitt researchers are designing new materials that selectively catch carbon dioxide in the atmosphere

13-Oct-2022 - Direct air capture may be key to saving Earth from the effects of climate change, but there’s a catch: It’s really hard to do. Direct air capture (DAC) technologies are designed to remove carbon dioxide from the air, although there’s still a lot of room for improvement in DAC materials. Other ...

Method efficiently breaks down plastic bottles into component parts

Researchers first to demonstrate use of metal-organic frameworks to degrade plastics

14-Apr-2022 - What if the life cycle of the plastic bottle was circular? Where a used plastic bottle was returned to its original components, ready to be made into a new plastic bottle instead of possibly ending up in a landfill. A Northwestern University research team is the first to demonstrate that a ...

Stabilizing gassy electrolytes could make ultra-low temperature batteries safer

New separator improves battery safety and its performance in the extreme cold

09-Jun-2021 - A new technology could dramatically improve the safety of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. Nanoengineers at the University of California San Diego developed a separator--the part of the battery that serves as a barrier between the anode and ...

Tandem catalytic system efficiently converts carbon dioxide to methanol

Encapsulating multiple molecular catalysts in nanoporous metal-organic frameworks central to efficient transformation

28-Jul-2020 - Converting carbon dioxide to methanol, a potentially renewable alternative fuel, offers an opportunity to simultaneously form an alternative fuel and cut down on carbon dioxide emissions. Inspired by naturally occurring processes, a team of Boston College chemists used a multi-catalyst system to ...

Key advance toward production of important biofuel

MOF can efficiently separate biobutanol from the fermentation broth

29-Apr-2020 - An international research collaboration has taken an important step toward the commercially viable manufacture of biobutanol, an alcohol whose strong potential as a fuel for gasoline-powered engines could pave the path away from fossil fuels. The key breakthrough is the development of a new metal ...

Adding a porous envelope to aluminum plasmonics

Gas-trapping framework married to light-powered nanocatalysts

13-Feb-2019 - When Rice University chemist and engineer Hossein Robatjazi set out to marry a molecular sieve called MOF to a plasmonic aluminum nanoparticle two years ago, he never imagined the key would be the same process nature uses to petrify wood. In a new paper Robatjazi and co-authors with Rice's ...

Making plastic production more energy efficient - with MOFs

30-Oct-2018 - An innovative filtering material may soon reduce the environmental cost of manufacturing plastic. Created by a team including scientists at the National Institute of Standards and Technology (NIST), the advance can extract the key ingredient in the most common form of plastic from a mixture of ...
