Dominique Langevin
Dominique Langevin (; born 24 July 1947) is a French researcher in physical chemistry. She is research director at the Centre national de la recherche scientifique and leads the liquid interface group in the Laboratory of Solid State Physics at the University of Paris-Sud. She was the Life and Physical Sciences Panel chair for the European Space Sciences Committee of the European Science Foundation from 2013-2021. Langevin studies liquid interfaces and interfacial rheology, the flow of matter at interfaces between liquids, or between a liquid and a gas. She is particularly interested in foams and emulsions and has made significant contributions relating the mechanical properties of interfaces to the stability of foams and emulsions. She has had a major role in bringing together scientists and mathematicians from multiple disciplines to develop the field of foam and emulsion science. Her books include ''Light Scattering by Liquid Surfaces and Complementary Techniques'' (1992) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Chemistry
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids). Some of the relationships that physical chemistry strives to resolve include the effects of: # Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids). # Reaction kinetics on the rate of a reaction. # The identity of ions and the electrical conductivity of materials. # Surface science and electrochemistry of cell membrane ...

Liquid Crystal
Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many types of LC phases, which can be distinguished by their optical properties (such as textures). The contrasting textures arise due to molecules within one area of material ("domain") being oriented in the same direction but different areas having different orientations. LC materials may not always be in a LC state of matter (just as water may be ice or water vapor). Liquid crystals can be divided into 3 main types: * thermotropic, *lyotropic, and * metallotropic. Thermotropic and lyotropic liquid crystals consist mostly of organic molecules, although a few minerals are also known. Thermotropic LCs exhibit a phase transition into the LC phase as temperature changes. Lyotropic LCs exhibit phase transitions as a function of b ...

Deutsche Physikalische Gesellschaft
The German Physical Society (German: , DPG) is the oldest organisation of physicists. The DPG's worldwide membership is cited as 60,547, as of 2019, making it the largest physics society in the world. It holds an annual conference () and multiple spring conferences (), which are held at various locations and along topical subjects of given sections of the DPG. The DPG serves the fields of pure and applied physics. Main aims are to bring its members and all physicists living in Germany closer together, represent their entirety outwards as well as foster the exchange of ideas between its members and foreign colleagues. The DPG binds itself and its members to advocate for freedom, tolerance, veracity and dignity in science and to be aware about the fact that the people working in science are responsible to a particularly high extent for the configuration of the overall human activity. Conferences and fostering young talent The DPG itself does not carry out any research, but its confer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Société Française De Physique
The Société Française de Physique (SFP), or the French Physical Society, is the main professional society of French physicists. It was founded in 1873 by Charles Joseph d'Almeida. History The French Physical Society is a state-approved non-profit scientific society aiming to promote the knowledge of physics. Its member include physicists living in France, regardless of background. As well as promoting physics, the SFP also acts as a lobbying organization with French policymakers alongside other scientific societies, the like the French Academy of Sciences, French Society of Mathematicians, and Union of Physicists. The SFP organizes a large number of events (conferences, workshops, exhibitions, etc.) for academic and general audiences. The SFP edits the ''Bulletin Newsletters'' and the review ''Reflets de la Physique''. Each year, the SFP awards several prizes to physicists in honor of specific works or actions towards the promotion of physics outside the community. The S ...

Microgravity
The term micro-g environment (also μg, often referred to by the term microgravity) is more or less synonymous with the terms ''weightlessness'' and ''zero-g'', but emphasising that g-forces are never exactly zero—just very small (on the International Space Station (ISS), for example, the small g-forces come from tidal effects, gravity from objects other than the Earth, such as astronauts, the spacecraft, and the Sun, air resistance, and astronaut movements that impart momentum to the space station). The symbol for microgravity, ''μg'', was used on the insignias of Space Shuttle flights STS-87 and STS-107, because these flights were devoted to microgravity research in low Earth orbit. The most commonly known microgravity environment can be found aboard the ISS which is located in low-earth orbit at an altitude of around 400 km, orbiting Earth approximately 15 times per day in what is considered free fall. The effects of free fall also enable the creation of short-du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
