Chemical Engineering
Chemical engineering is an engineering field which deals with the study of operation and design of chemical plants as well as methods of improving production. Chemical engineers develop economical commercial processes to convert raw materials into useful products. Chemical engineering uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials. The work of chemical engineers can range from the utilization of nanotechnology and nanomaterials in the laboratory to large-scale industrial processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products. Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, modeling, control engineering, chemical reaction engineering, nuclear engineering, biological engineering, construction specification, ...

Hydrazine
Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic unless handled in solution as, for example, hydrazine hydrate (). Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion. the world hydrazine hydrate market amounted to $350 million. About two million tons of hydrazine hydrate were used in foam blowing agents in 2015. Hydrazines r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henri Manuel
Henri Manuel (24 April 1874 – 11 September 1947) was a French photographer who served as the official photographer of the French government from 1914 to 1944. Photography studio In 1900, Manuel opened a portrait studio in Paris with his brother Gaston, which specialised in portrait photography. Manuel quickly became renowned as a photographer of people from the worlds of politics, art and sports, as well as a photographer of art and architecture. Soon his portraits were used by news agencies, and in 1910 Manuel's studio began providing a commercial service to news agencies for photographs known as "l'Agence universelle de reportage Henri Manuel". The studio became the largest photographic studio in Paris and a leading centre where young aspiring photographers such as Thérèse Bonney might go to work. In 1925, the brothers moved their business to 27 rue du Faubourg Montmartre, where they expanded their business into fashion photography for the likes of Chanel, Patou, Poire ...

Thérèse Tréfouël
Thérèse Tréfouël (née Boyer, 19 June 1892 — 9 November 1978) was a French chemist. Along with her husband, Jacques Tréfouël, she is best known for her research on sulfamides, a novel class of antibiotic drugs. Education and personal life Between 1913 and 1919, Tréfouël studied chemistry at the Faculté des Sciences, in Paris. She met her husband Jacques when they were assigned as lab partners after both failing to sign up to a practical course on time. Jacques and Thérèse married in 1921. They were known for the strength of their partnership and collaboration. Even after their retirement from scientific research, the Tréfouëls continued to collaborate on various projects: Jacques was fascinated by metalwork and woodwork, and would construct furniture which Thérèse upholstered. Research and career In the early 1920s, Thérèse and her husband worked at the Pasteur Institute, in the laboratory of Ernest Fourneau — known as the father of medicinal chemistry. ...

Jacques Tréfouël
Jacques Tréfouël (9 November 1897, Le Raincy – 11 July 1977, Paris) was a French medical chemist. He collaborated closely with his wife, Thérèse Tréfouël, including on the discovery of sulfanilamide. Biography From 1920 to 1928 he worked as an assistant to Ernest Fourneau in the laboratory of medicinal chemistry at the Pasteur Institute. For the next ten years, he served as laboratory chief at the Institute, during which time, he was involved in the synthesis and development of drugs such as stovarsol, orsanine and rhodoquine. In 1935, in collaboration with his wife, chemist Thérèse Tréfouël, and pharmacologists Daniel Bovet and Federico Nitti, he conducted research of prontosil, of which, they demonstrated that only a portion of the substance, named sulphanilamide, was active against streptococcus. The group also showed sulphanilamide's effective action against other types of bacteria (meningococcus, pneumococcus, gonococcus, Friedlander's bacillus, etc.).

Acetarsol
Acetarsol (or acetarsone) is an anti- infective drug. It was first discovered in 1921 at Pasteur Institute by Ernest Fourneau, and sold under the brand name Stovarsol. It has been given in the form of suppositories. Acetarsol can be used to make arsthinol. It has been cancelled and withdrawn from the market since August 12th, 1997. Medical uses Acetarsol has been used for the treatment of diseases such as syphilis, amoebiasis, yaws, trypanosomiasisiasis and malaria. Acetarsol was used for the treatment of ''Trichomonas Vaginalis'' and ''Candida Albicans.'' In the oral form, acetarsol can be used for the treatment of intestinal amoebiasis. As a suppository, acetarsol was researched to be used for the treatment of proctitis. Mechanism of Action Although the mechanism of action is not fully known, acetarsol may bind to protein-containing sulfhydryl groups located in the parasite, which then creates lethal As-S bonds, which then kills the parasite.

Jacques Monod
Jacques Lucien Monod (February 9, 1910 – May 31, 1976) was a French biochemist who won the Nobel Prize in Physiology or Medicine in 1965, sharing it with François Jacob and André Lwoff "for their discoveries concerning genetic control of enzyme and virus synthesis".'' Chance and Necessity: An Essay on the Natural Philosophy of Modern Biology'' by Jacques Monod, New York, Alfred A. Knopf, 1971, Monod and Jacob became famous for their work on the '' E. coli'' ''lac'' operon, which encodes proteins necessary for the transport and breakdown of the sugar lactose (lac). From their own work and the work of others, they came up with a model for how the levels of some proteins in a cell are controlled. In their model, the manufacture of proteins, such as the ones encoded within the ''lac'' (lactose) operon, is prevented when a repressor, encoded by a regulatory gene, binds to its operator, a specific site in the DNA sequence that is close to the genes encoding the proteins.
