Synthetic Resin
Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, such as acrylates or epoxides. Some synthetic resins have properties similar to natural plant resins, but many do not. Synthetic resins are of several classes. Some are manufactured by esterification of organic compounds. Some are thermosetting plastics in which the term "resin" is loosely applied to the reactant(s), the product, or both. "Resin" may be applied to one of two monomers in a copolymer, the other being called a "hardener", as in epoxy resins. For thermosetting plastics that require only one monomer, the monomer compound is the "resin". For example, liquid methyl methacrylate is often called the "resin" or "casting resin" while in the liquid state, before it polymerizes and "sets". After setting, the resulting poly(methyl methacrylate) (PMMA) is often renam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lahti
Lahti (; sv, Lahtis) is a city and municipality in Finland. It is the capital of the region of Päijänne Tavastia (Päijät-Häme) and its growing region is one of the main economic hubs of Finland. Lahti is situated on a bay at the southern end of lake Vesijärvi about north-east of the capital city Helsinki, south-west of the Heinola town and east of Hämeenlinna, the capital of the region of Tavastia Proper (Kanta-Häme). It is also situated at the intersection of Highway 4 (between Helsinki and Jyväskylä) and Highway 12 (between Tampere and Kouvola), which are the most significant main roads of Lahti. In English, the Finnish word Lahti literally means ''bay''. Lahti is also dubbed the "Chicago of Finland" due to the early industries of both cities, when they were known as " slaughterhouse cities".Lahti on Suomen Chi ...

Hybtonite
Hybtonite is trademark of Amroy Europe Oy for carbon nanoepoxy resins. It is a family of composite resins reinforced with carbon nanotubes (CNTs). The material and the manufacturing method were originally developed in the Nanoscience Center of the University of Jyväskylä during the years 2002 to 2004. Ultrasound is used to disperse the nanotubes and to create radicals at the ends of CNT molecules. CNTs can then chemically react with epoxy resin or other material forming strong covalent bonds. This results in a more durable hybrid composite structure that is between 20% and 30% stronger (with only 0.5% CNT contents) than a conventional reinforced plastic. The manufacturing process allows controlling the material properties such as electrical conductivity, thermal conductivity and viscosity. Different forms of hybtonite are available for different purposes such as laminating (glass fiber, carbon fiber), epoxy paints and glues. Applications The first application areas for hy ...

Carbon Nanotubes
A scanning tunneling microscopy image of a single-walled carbon nanotube Rotating single-walled zigzag carbon nanotube A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. ''Single-wall carbon nanotubes'' (''SWCNTs'') are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made this way, single-wall carbon nanotubes can be idealized as cutouts from a two-dimensional Hexagonal tiling, hexagonal lattice of carbon atoms rolled up along one of the Bravais lattice vectors of the hexagonal lattice to form a hollow cylinder. In this construction, periodic boundary conditions are imposed over the length of this roll-up vector to yield a helical lattice of seamlessly bonded carbon atoms on the cylinder surface. ''Multi-wall carbon nanotubes'' (''MWCNTs'') consisting of nested single-wall carbon nanotubes weakly bound together by van der Waals i ...

University Of Jyväskylä
The University of Jyväskylä ( fi, Jyväskylän yliopisto) is a research university in Jyväskylä, Finland. It has its origins in the first Finnish-speaking Teacher Training College (the so-called Teacher Seminary), founded in 1863. Around 14,000 students are currently enrolled in the degree programs of the university. History Founded in 1863, the university has its origins in the first Finnish-speaking teacher training college, the so-called Teacher Seminary. Uno Cygnaeus was enthusiastic to educate the people and created a programme for organising primary school education in Finland. Cygnaeus' plan was realised in 1863, when a teacher seminary was established in Jyväskylä, on the current university campus. Based on the town's central location, the first Finnish-medium secondary schools for boys and girls were also established in Jyväskylä. The foundation of the world-famous school system was created at the University of Jyväskylä. The teacher seminary evolved i ...

Covalent Bond
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full valence shell, corresponding to a stable electronic configuration. In organic chemistry, covalent bonding is much more common than ionic bonding. Covalent bonding also includes many kinds of interactions, including σ-bonding, π-bonding, metal-to-metal bonding, agostic interactions, bent bonds, three-center two-electron bonds and three-center four-electron bonds. The term ''covalent bond'' dates from 1939. The prefix ''co-'' means ''jointly, associated in action, partnered to a lesser degree, '' etc.; thus a "co-valent bond", in essence, means that the atoms share " valence", such a ...

Nanotechnology Companies
Nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
