Polskie Towarzystwo Chemiczne
The Polish Chemical Society () is a professional learned society of Polish chemists founded in 1919 to represent the interests of Polish chemists on the local, national and international levels. History The society was founded of 118 Charter Members on 29 June 1919 on the initiative of Leon Marchlewski, Stanisław Bądzyński and Ignacy Mościcki, future President of Poland who was a chemist himself. The initial aim of the organization was to bring together Polish chemists previously working under different partitions as well as from abroad. It was founded in three Polish cities: Lwów (today ''Lviv'' in Ukraine), Kraków, and Warsaw and the first scientific meeting was organized in Warsaw on 1 November 1919 by the executive board of the society. The Polish Chemical Society initiated a series of scientific conferences as well as founded Poland's first chemistry journal ''Roczniki Chemii''. After the Second World War, the society was reactivated in 1946 and continues its activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Learned Society
A learned society ( ; also scholarly, intellectual, or academic society) is an organization that exists to promote an academic discipline, profession, or a group of related disciplines such as the arts and sciences. Membership may be open to all, may require possession of some qualification, or may be an honour conferred by election. Most learned societies are non-profit organizations, and many are professional associations. Their activities typically include holding regular Academic conference, conferences for the presentation and discussion of new research results, and publishing or sponsoring academic journals in their discipline. Some also act as professional bodies, regulating the activities of their members in the public interest or the collective interest of the membership. History Some of the oldest learned societies are the (founded 1323), (founded 1488), (founded 1583), (founded 1603), (founded 1635), German National Academy of Sciences Leopoldina (founded 1652), ...

Marie Curie Medal
The Marie Curie-Skłodowska Medal is a Polish annual science awards, science award conferred by the Polish Chemical Society (Polish language, Polish: ''Polskie Towarzystwo Chemiczne'', PTCHem) to scientists working permanently abroad for contributions in the field of chemistry. Description It was named in honour of physicist Marie Curie (1867–1934) and first awarded in 1996. The winner receives a bronze medal depicting Marie Curie and on the reverse the Latin inscription ''Quo Magis Veritas Propagatur'' as well as the PTCHem logo, year and the name of the laureate.

Henry Louis Le Chatelier
Henry Louis Le Chatelier (; 8 October 1850 – 17 September 1936) was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists to predict the effect a changing condition has on a system in chemical equilibrium. Early life Le Chatelier was born on 8 October 1850 in Paris and was the son of French materials engineer Louis Le Chatelier and Louise Durand. His father was an influential figure who played important roles in the birth of the French aluminium industry, the introduction of the Martin-Siemens processes into the iron and steel industries, and the rise of railway transportation. Le Chatelier's father profoundly influenced his son's future. Henry Louis had one sister, Marie, and four brothers, Louis (1853–1928), Alfred (1855–1929), George (1857–1935), and André (1861–1929). His mother raised the children by regimen, described by Henry Louis: "I was accustomed to a very strict discipline: it was necessary to wak ...

Inorganic Chemistry
Inorganic chemistry deals with chemical synthesis, synthesis and behavior of inorganic compound, inorganic and organometallic chemistry, organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, pharmaceutical drug, medications, fuels, and agriculture. Occurrence Many inorganic compounds are found in nature as minerals. Soil may contain iron sulfide as pyrite or calcium sulfate as gypsum. Inorganic compounds are also found multitasking as biomolecules: as electrolytes (sodium chloride), in energy storage (Adenosine triphosphate, ATP) or in construction (the polyphosphate backbone in DNA). Bonding Inorganic compounds exhibit a range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Analytical Chemistry
Analytical skill, Analytical chemistry studies and uses instruments and methods to Separation process, separate, identify, and Quantification (science), quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative inorganic analysis, Qualitative analysis identifies analytes, while Quantitative analysis (chemistry), quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemistry, wet chemical methods and modern analytical techniques. Classical qualitative methods use separations such as Precipitation (chemistry), precipitation, Extraction (chemistry), extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
