Wöhler has also been regarded as a pioneering researcher in organic chemistry as a result of his 1828 demonstration of the laboratory synthesis of urea from ammonium cyanate, in a chemical reaction that came to be known as the "Wöhler synthesis". [5] [20] [21] Urea and ammonium cyanate are further examples of structural isomers of chemical ...
Wöhler demonstrated the reaction in his original publication with different sets of reactants: a combination of cyanic acid and ammonia, a combination of silver cyanate and ammonium chloride, a combination of lead cyanate and ammonia and finally from a combination of mercury cyanate and cyanatic ammonia (which is again cyanic acid with ammonia).

Rights of nature or Earth rights is a legal and jurisprudential theory that describes inherent rights as associated with ecosystems and species, similar to the concept of fundamental human rights. The rights of nature concept challenges twentieth-century laws as generally grounded in a flawed frame of nature as "resource" to be owned, used, and ...
The Inter-American Commission on Human Rights (the IACHR) is an autonomous organ of the Organization of American States, also based in Washington, D.C. Along with the Inter-American Court of Human Rights, based in San José, Costa Rica, it is one of the bodies that comprise the inter-American system for the promotion and protection of human ...
Natural rights were traditionally viewed as exclusively negative rights, [6] whereas human rights also comprise positive rights. [7] Even on a natural rights conception of human rights, the two terms may not be synonymous. The concept of natural rights is not universally accepted, partly due to its religious associations and perceived incoherence.
The term "human rights" has replaced the term "natural rights" in popularity, because the rights are less and less frequently seen as requiring natural law for their existence. [10] For some, the debate on human rights remains thus a debate around the correct interpretation of natural law, and human rights themselves a positive, but ...
Some notions of righteousness present in ancient law and religion are sometimes retrospectively included under the term "human rights". While Enlightenment philosophers suggest a secular social contract between the rulers and the ruled, ancient traditions derived similar conclusions from notions of divine law, and, in Hellenistic philosophy, natural law.
