Atmospheric CO2 concentrations continue to rise rapidly in response to increased combustion of fossil fuels, contributing to global climate change. In order to mitigate the effects of global warming, development of new materials for cost-effective and energy-efficient CO2 capture is critically important. Graphene-based porous materials are an emerging class of solid adsorbents for selectively removing CO2 from flue gases. Herein, we report a simple and scalable approach to produce three-dimensional holey graphene frameworks with tunable porosity and pore geometry, and demonstrate their application as high-performance CO2 adsorbents. These holey graphene macrostructures exhibit a significantly improved specific surface area and pore volume compared to their pristine counterparts, and can be effectively used in post-combustion CO2 adsorption systems bec...

The following is a helpful list of more than 300 terms and definitions commonly used in the car care industry. This list is provided by Robert Andre, the president of CarWash College™, a school offering numerous courses for training carwash managers and owners/operators in management, investment, repair and maintenance solutions. Abrasion: A general wearing away of a surface by constant scratching, usually due to the presence of foreign matter such as dirt, grit or metallic particles in the lubricant. Lack of proper lubrication may result in abrasion. Absorbent filter: A filter medium primarily intended to hold soluble and insoluble contaminants on its surface by molecular adhesion. Acid: Often represented by the generic formula HA, (H+A-) it is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a pH less than 7.0. Adhesive wear: Often referred to as galling, scuffing, scoring or seizing. It happens when sliding surfaces contact one another, causing fragments to be pulled from one surface and to adhere to the other. Air blowers: Aka blowers, dryers. Device which pushes air (blows) over a vehicle to remove water and help the drying...
