Not all of these compounds are bad for us, but a good proportion, including many of the aromatics, can raise the risk of cancer in sufficient doses, while also providing a starting point for reactions that generate atmospheric particulates and pollutants like ozone. What's never bee...
Prof. Ariel Furst and her colleagues at MIT have created a method of coating the bacteri a in tiny "metal-phenol network" (MPN) shells (外壳). The shells contained organic compounds called phenols, which are generally regarded as safe by the Food and Drug Administration.This new coating ...
and several devices are designed to do just that. Adding a carbon monoxide detector is a good start, but most are limited in the toxins they detect. More advanced air quality monitors such asAirthings View PlusandNest Protectwill register other volatile organic compounds (the bad stuff) and...
Hydrocarbons are compounds composed of mainly carbon and hydrogen atoms. Natural gas refers to naturally occurring mixture of hydrocarbon gas used as a source of energy. It is commonly made up of methane and some are composed of other alkanes with little amount of other gases such as carbon ...
Greenhouse gases are gaseous compounds that have the ability to trap heat in Earth's atmosphere, causing gradual warming of the climate. Human activities contribute to the amount of greenhouse gases that exist. Examples of such activity include livestock farming, deforestation, and the use of ...
In fact, you can’t even ignite it with a lit cigarette. Furthermore, LNG is lighter than air, so spills dissipate rapidly, virtually eliminating the risk of catastrophic events and spills. LNG is also a cleaner fuel than regular methane, as it’s been processed and the harmful compounds ...
However, many of these "new" gases contain compounds that are not ordinarily present in natural gas, and these chemical species can have adverse effects on the integrity of the infrastructure, the safety and performance of end-use equipment, and even on the health of the end user. In the ...
Stored liquids, especially crude oils, can give off hydrocarbon vapours or othervolatile organic compounds. When mixed with air, it can be highly explosive. Therefore, these vapours are collected and safely moved to the vapour recovery tanks in the terminal after removing the sulfur component. ...
Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy. Convection that occurs naturally is called natural convection or free convection...
Lectins were discovered almost 130 years ago, in 1888. That’s well over a decade before aviation, something we have since mastered. Yet these commonly occurring compounds largely remain a mystery. And while you may not be flying every day, it’s guaranteed that you are eating foods containin...
