One of the first plastics made from synthetic components, Bakelite was used for its electrical nonconductivity and heat-resistant properties in electrical insulators, radio and telephone casings, and such diverse products as kitchenware, jewelry, pipe stems, and children's toys.

In 1993 Bakelite was designated a National Historic Chemical Landmark by the American Chemical Society in recognition of its significance as the world's first synthetic plastic.

It was the very first synthetic thermosetting plastic ever made.

Chemical elements may also be categorized by their origin on Earth, with the first 98 considered to be naturally occurring, while those with atomic numbers beyond 98 have only been produced artificially as the synthetic products of man-made nuclear reactions.

The first human-made ( synthetic ) organic dye, mauveine, was discovered serendipitously by William Henry Perkin in 1856.

Hydrothermal synthetic emeralds have been attributed to IG Farben, Nacken, Tairus, and others, but the first satisfactory commercial product was that of Johann Lechleitner of Innsbruck, Austria, which appeared on the market in the 1960s.

* 1909 – Belgian chemist Leo Baekeland announces the creation of Bakelite, the world's first synthetic plastic.

At first Gris painted in the analytic style of Cubism, but after 1913 he began his conversion to synthetic Cubism, of which he became a steadfast interpreter, with extensive use of papier collé or, collage.

Positronium atoms, synthetic penicillin, synthetic self-replicating molecules, and the genetic bases for Lou Gehrig's disease and Huntington's disease were first discovered at MIT.

In October 2007, a team of scientists headed by DNA researcher Craig Venter and Nobel laureate Hamilton Smith announced that they plan to create the first artificial life form in history by creating a synthetic chromosome, which they plan to inject into the M. genitalium bacterium, with potential to result in an artificial species dubbed Mycoplasma laboratorium or Mycoplasma JCVI-1. 0 after the research centre in which it was created, the J. Craig Venter Institute in the United States.

A team of chemists led by Louis Fieser at Harvard University was the first one to develop synthetic napalm, during 1942 for the U. S. Armed Forces.

Since the invention of the first synthetic polymer product, bakelite, synthetic polymer products have frequently been invented.

The quinolones are a family of synthetic broad-spectrum antibacterial drugs The first generation of the quinolones begins with the introduction of nalidixic acid in 1962 for treatment of urinary tract infections in humans.

* First to discover that missing pulmonary surfactants are the culprit in the death of newborns with respiratory distress syndrome ; first to develop a synthetic substitute for it, reducing infant death rates significantly

Heavier particles settle out first, so gravel will be on the bottom, sand above, silt above that and very fine clay and organic matter will stay in suspension for days.

Biodynamic agriculture, the first intentional form of organic farming, began in the 1920s when Rudolf Steiner gave a series of lectures since published as Agriculture.

" Therefore I should infer from analogy that probably all the organic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed.

The term was first used in a 1994 book by Joseph Jenkins that advocates the use of this organic soil amendment.

The first industrial station for the transformation of urban organic materials into compost was set up in Wels / Austria in the year 1921.

The first form of citizenship was based on the way people lived in the ancient Greek times, in small-scale organic communities of the polis.

* Carl Ritter ( 1779 – 1859 ), considered to be one of the founding fathers of modern geography and first chair in geography at the Humboldt University of Berlin, also noted for his use of organic analogy in his works.

In the first ( that is employed by the majority of bacteria, some archaea, yeasts, algae and fungi ), organic compounds are accumulated in the cytoplasm – these osmoprotectants are known as compatible solutes.

This committee was the first international conference to create an international naming system for organic compounds.

In the first case, Agin discussed falsified results in the development of organic transistors: ' As far as understanding junk science is concerned, the important aspect is that both Bell Laboratories and the international physics community were fooled until someone noticed that noise records published by Jan Hendrik Schön in several papers were identical-which means physically impossible.

During the first half of the nineteenth century, scientists realized that organic compounds can be synthesized in the laboratory.

The first formal formulation was proposed by Étienne Serres in 1824 – 26 as what became known as the " Meckel-Serres Law ", it attempted to provide a link between comparative embryology and a " pattern of unification " in the organic world.

The embryo's nervous system is one of the first organic systems to grow.

The term was first used by organic chemist Ludwig Brieger ( 1849 – 1919 ).

Organic radiotracer molecules that will contain a positron-emitting radioisotope cannot be synthesized first and then the radioisotope prepared within them, because bombardment with a cyclotron to prepare the radioisotope destroys any organic carrier for it.

Instead, the isotope must be prepared first, then afterward, the chemistry to prepare any organic radiotracer ( such as FDG ) accomplished very quickly, in the short time before the isotope decays.

He also founded a system of organic agriculture, now known as Biodynamic agriculture, which was one of the very first forms of, and has contributed significantly to the development of, modern organic farming.

The hilt, either from organic materials or bronze ( the latter often highly decorated with spiral patterns, for example ), at first simply allowed a firm grip and prevented the hand from slipping onto the blade when executing a thrust or the sword slipping out of the hand in a cut.

Michelle Obama planted the White Houses ' first organic garden and installed beehives on the South Lawn of the White House, which will supply organic produce and honey to the First Family and for state dinners and other official gatherings.

The first structure of an organic compound, hexamethylenetetramine, was solved in 1923.
