Ideally, research is supposed to create knowledge that can be used to increase people’s wellbeing (e.g. to dissolve vital problems), or simply to increase our understanding of things. The purpose of eduion, at least ideally, is to encourage critical enquiry and to open minds to arguments for and against any particular conclusion, rather than close them to any conclusion but one.
Nitric acid - Wikipedia
The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO 3, it is referred to as fuming nitric acid..

Petroleum Processing Overview 1.2.1 7 The Chemicals in Petroleum Carbon is present in almost all of the chemical compounds in petroleum. If you’ve ever taken a chemistry class, you know that carbon, more than any other element, binds to itself to form straight chains, branched chains, rings, and complex three-dimensional structures.
Thermochemical biofuel production in hydrothermal …
First published on 9th July 2008 Hydrothermal technologies are broadly defined as chemical and physical transformations in high-temperature (200–600 C), high-pressure (5–40 MPa) liquid or supercritical water.This thermochemical means of reforming biomass may have energetic advantages, since, when water is heated at high pressures a phase change to steam is avoided which avoids large

About 78% of these emissions come from the coustion of waste products (e.g., petroleum coke and still gas), petroleum fuels, and natural gas (44, 45). CCS applied to these emissions may incur comparable or slightly greater costs than for electric power plants ( 15 , 46 ), with chemical absorption being the most promising method for CO 2 removal.
