Copper exchanged FAU nanozeolite as non-toxic nitric oxide and carbon dioxide gas carrier

Water vapour and carbon dioxide decrease nitric oxide readings.

Measurement of nitric oxide levels in exhaled air is commonly performed using a chemiluminescence detector. However, water vapour and carbon dioxide affect the chemiluminescence process. The influence of these gases at the concentrations present in exhaled air, has not yet been studied. For this in vitro study, mixtures of 50, 100 and 200 parts per billion (ppb) NO in air were prepared and fed ...

Zinc oxide nano-crystals assisted for carbon dioxide gas sensing; prepared by solvothermal and sonochemical methods

ZnO nanostructures of different methods and sizes were grown in a controlled manner using a simple hydrothermal and sonochemical technique. Controlling the content of concentration and temperature of the reaction mixture, spherical nanoparticles ZnO structures could be synthesized at temperatures 100-150 °C with excellent reproducibility in solvothermal and at different power and time in sonoch...

Adsorption of Carbon Dioxide on Alkali Metal Exchanged Zeolites

Capturing carbon dioxide as a polymer from natural gas

Natural gas is considered the cleanest and recently the most abundant fossil fuel source, yet when it is extracted from wells, it often contains 10-20 mol% carbon dioxide (20-40 wt%), which is generally vented to the atmosphere. Efforts are underway to contain this carbon dioxide at the well-head using inexpensive and non-corrosive methods. Here we report nucleophilic porous carbons are synthes...
