Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions [3] that can be thought of as a microscopic "sponge" structure (adsorption ...
The bright colors of Grand Prismatic Spring, Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus 'extreme' and Ancient Greek φιλία (philía) 'love') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what known ...
[1] [2] Activated carbon beds vary in lifetime depending on the concentration of the pollutant(s) being removed, their associated adsorption isotherms, inlet flow rates and required discharge consents. Life- times of these beds can range between hours and months.
Powdered Activated Carbon Treatment (PACT) is a wastewater technology in which powdered activated carbon [1] [2] is added to an anaerobic or aerobic treatment system. [3] The carbon in the biological treatment process adsorbs recalcitrant compounds that are not readily biodegradable, thereby reducing the chemical oxygen demand of the wastewater and removing toxins.

Carbon is the sixth element, with a ground-state electron configuration of 1s 2 2s 2 2p 2, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements.
Galdieria sulphuraria is an extremophilic unicellular species of red algae.It is the type species of the genus Galdieria. [2] It is known for its broad metabolic capacities, including photosynthesis and heterotrophic growth on over 50 different extracellular carbon sources.
1. Health conditions. Panting can be a symptom of some of the most common illnesses that cats can get. Conditions like asthma, congestive heart failure, severe viral infections, anemia, and cancer ...
[2] [3] Because it is lightweight and relatively small in size, carbon molecules are easy for enzymes to manipulate. Carbonic anhydrase is part of this process. Carbon has an atomic number of 6 on the periodic table. The carbon cycle is a biogeochemical cycle that is important in maintaining life on Earth over a long time span.
