Activated Charcoal is a fine, odorless, black powder often used in emergency rooms to treat overdoses. Charcoal is made from coal, wood, or other substances. It becomes “activated charcoal” when high temperatures combine with a gas or activating agent to expand its surface area. It is.....
Biochar is a carbon-rich solid that is derived from biomass that is heated in a limited oxygen environment. It is charcoal used as a soil amendment for both carbon sequestration and soil health benefits. It is a type of fine-grained charcoal created by burning wood and agricultural byproducts slo.....
Biradial symmetry is observed in species that exhibit both bilateral and radial symmetry with morphological (internal or external) characteristics. It’s distinct from radial symmetry since the organism is separated by two planes but not more than two. It may represent an intermediate stage .....
Acetoacetic acid (AcAc), also known as ‘diacetic acid’, is a weak organic acid that can be produced in the human liver under certain poor metabolism conditions that lead to excessive breakdown of fatty acids. It’s chemical formula CH3COCH2COOH, and acetoacetic acid is a weak acid. It’.....
Biological symmetry refers to the symmetry found in organisms, including plants, animals, fungi, and bacteria. Specifically, symmetry refers to correspondence of body parts, in size, shape, and relative position, on opposite sides of differentiation or distributed around a central point or axis. .....
Belgrade (/ˈbɛlɡreɪd/ BEL-grayd; Serbian: Beograd/Београд, lit. ‘White City’, pronounced – beǒɡrad) city, capital of Serbia, and it lies at the confluence of the Danube and Sava rivers in the north-central part of the country. About 1.7 million people live within the city o.....
Naphthalene is a white, volatile, solid polycyclic hydrocarbon with a powerful smell of mothball, and its chemical formula is C10H8. It is detectable at concentrations as low as 0.08 ppm by mass. It is an important raw material of hydrocarbon which gives rise to a host of substitute products used.....
Alcohol dehydrogenases (ADH) are a group of dehydrogenase enzymes that occur in many species and promote the interconversion of alcohols and aldehydes or ketones to NADH by reducing the nicotinamide adenine dinucleotide (NAD+). The prefix ‘de’ means not, and ‘hydro’ refers to a hydrogen a.....
Heterogeneous catalysis is a type of catalysis where the catalyst occupies a different phase from the mixture of reactions. Phase distinguishes between not only components of solid, liquid and gas, but also immiscible mixtures (e.g., oil and water), or anywhere an interface occurs. Since the surf.....
Homogeneous catalysts allow greater interaction with the mixture of reactions than heterogeneous catalysts do. Homogeneous catalysis in chemistry is the catalysis by a soluble catalyst in a solution. The advent and rapid growth of new areas of homogeneous catalysis, such as photoredox, electro- a.....
Both CDs and DVDs are great for file storage. Both CDs and DVDs have pits or dark spots on the medium encoding the data. Generally speaking, a DVD can store more data than a CD, which is one of the reasons why CD contains the polycarbonate substratum on only one side while it is on […]
