Sensors for carbon dioxide are an example of this approach and they have been commercially available for several years. Cross-sensitivity of electronic chemical sensors may also be utilized to design chemical sensor arrays , which utilize a variety of specific sensors that are cross-reactive for fingerprint detection of target gases in complex ...
Stay healthy and hydrated with these better-for-you seltzer and sparkling water brands that have low PFAS levels, are eco-friendly, and taste great. ... Their cans are BPA-free and contain ultra ...
The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization .
A recent study by the Center for Environmental Health (CEH) has revealed high levels of metal arsenic in two brands of bottled water sold by Whole Foods and Walmart.
The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light. NDIR sensors are most often used for measuring carbon dioxide.

Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...
Two sets of Houston homeowners have been left high and dry after a municipal water tank exploded behind their homes, unleashing thousands of gallons of water that tore down an eight-foot fence and ...
An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction. One form of electro-galvanic fuel cell based on the oxidation of lead is commonly used to measure the concentration of oxygen gas in underwater diving and medical breathing gases .
