Szombathely
} Szombathely (; ; also see #Etymology, names) is the 10th largest city in Hungary. It is the administrative centre of Vas County in the west of the country, located near the border with Austria. Szombathely lies by the streams ''Perint'' and ''Gyöngyös'' (literally "pearly"), where the Alpokalja (Lower Alps) mountains meet the Little Hungarian Plain. The oldest city in Hungary, Szombathely is known as the birthplace of Saint Martin of Tours. Etymology The name ''Szombathely'' is from the Hungarian language, Hungarian ''szombat'', "Saturday" and ''hely'', "place", referring to its status as a market town, and the medieval markets held on Saturday every week. Once a year during August they hold a carnival to remember the history of "Savaria". The Latin name ''Savaria'' or ''Sabaria'' comes from ''Sibaris'', the Latin name of the river ''Gyöngyös (river), Gyöngyös'' (German ''Güns''). The root of the word is the Proto-Indo-European language, Proto-Indo-European word ''*seu' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halle (Saale)
Halle (Saale), or simply Halle (), is the second largest city of the States of Germany, German state of Saxony-Anhalt. It is the sixth-most populous city in the area of former East Germany after (East Berlin, East) Berlin, Leipzig, Dresden, Chemnitz and Magdeburg as well as the List of cities in Germany by population, 31st-largest city of Germany. With around 226,000 inhabitants, it is less populous than the state capital, Magdeburg. With Leipzig, the largest city of Saxony, Halle forms the polycentric metropolitan area, polycentric Leipzig-Halle conurbation. Leipzig/Halle Airport, Leipzig/Halle International Airport lies between the two cities, in Schkeuditz. The Leipzig-Halle conurbation is at the heart of the larger Central German Metropolitan Region. Halle has been known by many names throughout its history. From the 15th to the 17th century: ''Hall in Sachsen''. From then until the beginning of the 20th century, the name Halle an der Saale was used, and still remains a more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liquid Crystals
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 can flow like a liquid, but its molecules may be oriented in a common direction as in a solid. 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. An LC material may not always be in an LC state of matter (just as water may be ice or water vapour). Liquid crystals can be divided into three 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 a ...

Kent State University Faculty
Kent is a ceremonial county in South East England. It is bordered by Essex across the Thames Estuary to the north, the Strait of Dover to the south-east, East Sussex to the south-west, Surrey to the west, and Greater London to the north-west. The county town is Maidstone. The county has an area of and had population of 1,875,893 in 2022, making it the fifth most populous county in England. The north of the county contains a conurbation which includes the towns of Chatham, Gillingham, and Rochester. Other large towns are Maidstone and Ashford, and the borough of Canterbury holds city status. For local government purposes Kent consists of a non-metropolitan county, with twelve districts, and the unitary authority area of Medway. The county historically included south-east Greater London, and is one of the home counties. The north of Kent is a plain bordering the Thames Estuary. South of this is the North Downs, a chalk downland ridge which crosses the county from north- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piezoelectricity
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied. The inverse piezoelectric effect is used in the pro ...

Flexoelectricity
Flexoelectricity is a property of a dielectric material where there is coupling between electrical polarization and a strain gradient. This phenomenon is closely related to piezoelectricity, but while piezoelectricity refers to polarization due to uniform strain, flexoelectricity specifically involves polarization due to strain that varies from point to point in the material. This nonuniform strain breaks centrosymmetry, meaning that unlike in piezoelectricity, flexoelectric effects occur in both centrosymmetric and asymmetric crystal structures. This property is not the same as ferroelasticity. It plays a critical role in explaining many interesting electromechanical behaviors in hard crystalline materials and core mechanoelectric transduction phenomena in soft biomaterials. Additionally, it is a size-dependent effect that becomes more significant in nanoscale systems, such as crack tips. In common usage, flexoelectricity is the generation of polarization due to a strain gradie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrospinning
Electrospinning is a fiber production method that uses Electrostatics, electrical force (based on electrohydrodynamic principles) to draw charged threads of polymer solutions for producing nanofibers with diameters ranging from nanometers to micrometers. Electrospinning shares characteristics of both electrospraying and conventional solution spinning (polymers)#Dry spinning, dry spinning of fibers.Ziabicki, A. (1976) ''Fundamentals of fiber formation'', John Wiley and Sons, London, . The process does not require the use of coagulation chemistry or high temperatures to produce solid threads from solution. This makes the process particularly suited to the production of fibers using large and complex molecules. Electrospinning from molten precursors is also practiced; this method ensures that no solvent can be carried over into the final product. Process When a sufficiently high voltage is applied to a liquid droplet, the body of the liquid becomes charged, and electrostatic repuls ...
