How catalysts remove dangerous nitrogen oxides

”If we know exactly where the reaction takes place, the production of catalysts can be controlled accordingly”

11-Oct-2024 - Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual iron atoms sitting in certain neighbouring ...

Cellular Communication Agent

Tracking the NO signaling pathway

26-Aug-2021 - Both nitric oxide (NO) and hydrogen sulfide (H2S) act as gaseous signaling molecules with similar physiological effects. Many of the critical questions about the interplay between these two gasotransmitters hinge on their chemical reactivity and the fleeting existence of HSNO, a key product of ...

Deciphering the 'mosaic' of the brain

Discovery sheds new light on how neurodegenerative diseases might occur

11-Apr-2018 - Researchers from the University of Leicester have shed new light on how neurons in the brain communicate with one another. This could potentially help in our understanding of how and why a range of neurodegenerative diseases occur. The team, led by Dr Joern Steinert from the MRC Toxicology Unit ...

Staph uses nitric oxide enzyme to colonize noses

30-Nov-2016 - Staph bacteria colonize nasal passages through a newly discovered function for a primeval biochemical mechanism. The interior of the nose is a prime dwelling place for some forms of staph. More than one-third of the population has a chronic presence of Staphylococcus aureus in their nostrils and ...

Nanobionic spinach plants can detect explosives

After sensing dangerous chemicals, the carbon-nanotube-enhanced plants send an alert.

01-Nov-2016 - Spinach is no longer just a superfood: By embedding leaves with carbon nanotubes, MIT engineers have transformed spinach plants into sensors that can detect explosives and wirelessly relay that information to a handheld device similar to a smartphone. This is one of the first demonstrations of ...

Messenger substance live on show

Important messenger substance in human cells measured 'live' for the first time

12-Apr-2016 - Scientists have succeeded in making real-time measurements of changes in the concentration of the important messenger substance nitric oxide (NO) in human cells for the first time. The breakthrough, which has been published in the journal "Nature Communications", was achieved by fusing two ...

Soil crusts emit nitrogen oxides and nitrous acid

Study shows that biological soil crusts release large quantities of reactive nitrogen compounds

03-Dec-2015 - For a long time now, researchers have been racking their brains over the large quantities of reactive nitrogen compounds observed in arid regions after periods of rainfall without being able to identify the source. A study is now bringing light into the darkness. Bettina Weber and her colleagues ...

Nanotube-based sensors can be implanted under the skin for a year

05-Nov-2013 - Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous ...

Portable and precise gas sensor could monitor pollution and detect disease

22-Sep-2009 - In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. Nitric oxide, a gas well known to scientists for its myriad functions, has proven challenging to measure accurately outside the laboratory. A team of Princeton and ...

New method for detecting nitroxyl will boost cardiac drug research

07-Jul-2009 - Wake Forest University scientists have developed a new research tool in the pursuit of heart medications based on the compound nitroxyl by identifying unique chemical markers for its presence in biological systems. Nitroxyl, a cousin to the blood-vessel relaxing compound nitric oxide, has been ...
