Destructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols.
A series of processes that involve carbonization. [2]Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization.
Creative destruction (German: schöpferische Zerstörung) is a concept in economics that describes a process in which new innovations replace and make obsolete older innovations. [ 1 ] The concept is usually identified with the Austrian economist Joseph Schumpeter , [ 2 ] [ 3 ] [ 4 ] who derived it from the work of Karl Marx and popularized it ...
Peacebuilding is an activity that aims to resolve injustice in nonviolent ways and to transform the cultural and structural conditions that generate deadly or destructive conflict. It revolves around developing constructive personal, group, and political relationships across ethnic, religious, class, national, and racial boundaries.
Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change. Physical weathering involves the breakdown of rocks into smaller fragments through processes such as expansion and contraction, mainly due to temperature changes.
There are destructive processes and nondestructive processes. Metal testing can also include, determining the properties of newly forged metal alloys. With many chemical-property databases readily available, identification of unmarked pure, common metals can be a quick and easy process. Leaving the original sample in complete, re-usable condition.
Mass wasting is a general term for any process of erosion that is driven by gravity and in which the transported soil and rock is not entrained in a moving medium, such as water, wind, or ice. [2] The presence of water usually aids mass wasting, but the water is not abundant enough to be regarded as a transporting medium.
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. [1]
