Scandinavian design is world famous for the simplicity, good function, natural raw materials and good craftsmanship, and the Danish furniture traditions are strong and highly respected.
However, the strong promotion of the traditional Scandinavian furniture classics can tend to prohibit the introduction of new talented designers and the general development of New Scandinavian Design.
At the same time, is Scandinavian design furniture most often fairly expensive and thereby only within reach for the few.
By initiating the Bolia Design Awards and awarding design innovation based on the Scandinavian furniture traditions combined with the aim to reach affordable prices, we wish to support new talented designers and thereby the development of the New Scandinavian Design.
The Bolia Design Awards is open for any corporate or private designer, who has a passion for furniture and a desire to be a part of the development of New Scandinavian Design.
The theme: New Scandinavian Design
The objective is to design a piece of furniture for living-, dining or bedroom. It must be a single product, i.e. a sofa, a swivel chair, a dining- or coffee table, a dining chair or a bed.

A: Switching to ecomate in almost all cases requires little to no processing changes. Any changes that might be necessary are standard to any chemical system change. Typical process changes would be changes to metering and slight temperature changes. Most customers have made the transition from less than $500.
Bueno aquí dicen que el ciclopentano si es un material muy ecológico en cuestiones de aislamiento. Sin embargo aunque es utilizado en Europa aquí en América no es muy popular. Sin embargo tenemos nuestro sustituto que es el Ecomate.

De CFCs a agentes soplantes verdes
La preocupación por la protección de la capa de ozono comenzó hace 20 años, cuando se descubrieron los efectos que en ella tenían los CFCs (cloro-fluoro-carbonos) y otras sustancias. El proceso de eliminación de los CFCs ha tomado caminos diferentes en América y Europa. Desde 1992, las industrias europeas reemplazaron el R-11 (el agente soplante más común de la época) por el ciclo-pentano, en un lapso de tiempo relativamente corto. Sin embargo, el ciclopentano no ha sido exitoso en Norte América, donde los principales contendores son el HFC 245fa y en menor proporción el HFC 134a (generalmente con altos niveles de agua para co-soplar con CO2), el ciclopentano, el n-pentano y el isopentano.
Los nuevos participantes en esta región del planeta son los agentes soplantes basados en metil-formato y Ecomate, el último desarrollo de Foam Supplies Inc. De acuerdo con la empresa, Ecomate tiene valores de DPO y HGWP de cero y un valor "k" de 0.16, convirtiéndolo en un excelente aislante. Su precio se encuentra en el rango de los pentanos y sus características de flamabilidad son similares a las del HCFC 141b. Presenta muy buena estabilidad dimensional a temperaturas y humedades tanto altas como bajas. Según Foam Supplies Inc, un sistemas para espumas que contenga 15% de HCFC 141b puede emplear entre 5%-6% de Ecomat para obtener la misma densidad. Ecomat es comercializado en América por la compañía A-gas.
Frigoríficos domésticos, aparatos de frío comercial y congeladores | Los sistemas de Elastopor H®, expandidos en su mayoría con ciclopentano (puro o con otras mezclas de hidrocarburos), garantizan un muy buen consumo energético del aparato, siendo este punto juntamente con el respeto al medio ambiente la clave para el desarrollo de futuros productos. |
Termos eléctricos | Elastopor H® es el material idóneo para el aislamiento de calentadores de agua. La espuma de poliuretano es expandida para esta aplicación predominantemente con agua. Estos sistemas permiten ser procesados por inyección con o sin molde, siendo también adecuados para la espumación in situ de tanques de agua caliente. |

Básicamente hay solo 2 tipos de refrigeradores, con 1 o 2 motores
Los de 2 motores tienen el congelador en la parte baja y el “frigorífico” en la parte alta, presentan la ventaja de que se puede controlar completamente por separado la temperatura de ambos
Con un motor puede variar la posición del congelador, y debido al proceso de enfriamiento del refrigerador no se puede poner el congelador en medio y el refrigerador en dos partes en los extremos

A new magnetic-cooling system could lead to more-energy-efficient refrigerators.
Cool tool: This preliminary version of an energy-efficient magnetic fridge shows a ring-shaped 1.2-tesla magnet. The magnet can encompass a movable cylinder containing materials that heat up in the presence of a magnetic field and cool down when the field is removed. As it cools, the material absorbs heat from its surroundings.

Modern coolers and fridges may not cause holes in the ozone layer like their pre-1994 counterparts, but they still use greenhouse gases that are warming the planet. Their compressors also consume a lot of energy: air conditioners and refrigerators used about 340 billion kilowatt hours in 2005--nearly 30 percent of the total energy used in U.S. homes.
Researchers at the Risoe National Laboratory, in Roskilde, Denmark, are now one step closer to building a magnetic-cooling system that promises energy-efficient, environmentally friendly, and completely silent fridges. Temperatures in conventional fridges swing between −20 and 20 ºC. Achieving this 40 ºC temperature span is one of the most significant challenges with magnetic refrigeration. The Danish researchers have built a refrigerator that can vary temperature by almost 9 ºC.
This is an important step toward practical temperature spans of 40 ºC, says Nini Pryds, a senior scientist at Risoe who is leading the work. The research team is now working with Danfoss, one of the largest compressor manufacturers in the world, to build a commercial prototype; the company says that it should be ready by 2010.
Magnetic-cooling technology exploits materials that heat up when exposed to a magnetic field and cool down when the magnetic field is removed. As the material cools down, it pulls heat out of its surroundings. The larger the difference between the hottest and coldest temperatures achieved under the influence of a magnetic field, the better the material is at cooling.
Magnetic coolers have been used for years in laboratories for cryogenic temperatures tens of degrees below zero. In 1995, Ames Laboratory, in Iowa, demonstrated the first magnetic refrigerator that cooled contents in a room-temperature environment. The company used the metal gadolinium.
Since then, researchers have found many other materials that work at room temperature. The problem is that the temperature swings in all these substances is only a few degrees. "Achieving a large change of temperature is easy if you use a superconducting magnet," Pryds says. But superconducting magnets are large and require cooling themselves, making them impractical for everyday appliances such as household fridges and air conditioners. For these applications, he says, "the only way to go is a permanent magnet." Ideally, it should be a small, cheap magnet with a field of less than one tesla.
Getting large temperature spans with a permanent magnet calls for some clever engineering. Typically, it means using cooling liquids such as water. The material, with water circulating around it, is alternately placed in and out of a magnetic field. When it's in the field, it heats up. The circulating water draws heat from the material and transfers it to a heat sink. Then the magnetic field is removed, and the material, which was already being cooled by the water, cools down even more. As it cools, it absorbs heat from the water, making it cold enough to be used as the refrigerator. This hot-cold cycle is repeated over and over.
Putting the different pieces--material, magnets, liquid cooling--together in a practical magnetic refrigerator is tough. Researchers need to design a system that gets at least a 40 ºC temperature change and enough cooling power--fridges currently have powers of as much as 150 watts--using a permanent magnet with a magnetic field less than one tesla. That requires a delicate balance between the system's parameters. For instance, as researchers expand the temperature span, the cooling power might go down, or the system may need more energy. "It's an engineering nightmare," says Ames Laboratory researcher Karl Gschneidner, a pioneer in magnetic cooling.
But the rewards will be plenty. Magnetic refrigerators will be much more energy efficient than conventional fridges because they only need energy to circulate the water. "The energy consumption of magnetic refrigerators [should] be as much as 60 percent lower than traditional refrigeration," Pryds says. Also, unlike conventional fridges, magnetic systems do not need refrigerants such as hydrofluorocarbons, which are potent greenhouse gases.
Pryds is confident that his group's work will lead to commercial magnetic fridges. Like other research teams, the Risoe group is using the water-cooling design. But while most research teams are using gadolinium powder, the Danish researchers use plates made from a ceramic material containing lanthanum, strontium, calcium, and manganese. Pryds says that "ceramics are chemically stable; they don't corrode in corroding fluids such as water." The ceramic plates should also be easier to manufacture on a large scale. The combination of ceramic material and the researchers' final refrigerator design--which is not yet public--could lead to practical success, he says.
The researchers face some tough competitors, though. Ames Laboratory researchers, working with Milwaukee-based Aeronautics Corporation of America, have made systems with temperature spans of 25 ºC and 95 watts of cooling power using 1.5-tesla magnets. Andrew Rowe and his colleagues at the University of Victoria, in Canada, have made 15-watt cooling systems with temperature spans of 30 ºC. Meanwhile, researchers at Chubu Electric Power and Toshiba, in Japan, have gone down to about 0.8 teslas to get a 10 ºC span.
Things are looking up, Gschneidner says, and in another 5 to 10 years, magnetic fridges should be on the market. Many research groups are now working on magnetic refrigerators, making better materials and coming up with better system designs. Also, adds Rowe, permanent magnets are getting smaller and cheaper. "The basic principles have been shown and demonstrated," he says. "Magnetic refrigeration works. Now we need some hard thinking [and] good designs, and hopefully these things will come together."
A material developed by researchers at the University of California, Riverside can take on any color of the rainbow, simply by the scientists changing the distance between the material and a magnet. It could be used in sensors or, encapsulated in microcapsules, in rewritable posters or other large color displays.
The researchers made the material using a high-temperature method to synthesize nanoscale, crystalline particles of magnetite, a form of iron oxide. Each particle was made about 10 nanometers in diameter because, as they get much larger than this, magnetite particles become permanent magnets, and therefore would cluster together and fall out of solution. The 10-nanometer particles group together to form uniformly sized spherical clusters, each about 120 nanometers across; in tests, these clusters have stayed suspended in solution for months.
By coating these clusters with an electrically charged surfactant, the researchers cause the clusters to repel each other. When researchers use a magnet to counteract the repellent forces, the clusters rearrange and move closer together, changing the color of the light they reflect. The stronger the magnetic field, the closer the particles, with the color changing from the red end of the spectrum toward the blue, opposite end, as the magnet gets closer to the material. Moving the magnet away allows the electrostatic charge to force the particles apart again, returning the system to its original condition.
"The beauty of this system is that it is so simple," says Orlin Velev, a chemistry and biomolecular-engineering professor at North Carolina State University. "It can be used over large areas because it's very inexpensive and very easy to make." The work is published in the early online edition of the journal Angewandte Chemie.
A number of other researchers have developed color-changing materials, some of which are also controlled with magnetic forces; others use electrical or mechanical forces. The Riverside researchers, led by Yadong Yin, a professor of chemistry, however, are able to pack far more magnetic material per spherical building block that was previously possible. Sanford Asher, a professor of chemistry and materials science at the University of Pittsburgh who has encapsulated magnetite particles in polymer spheres, says that the new approach increases the amount of magnetic material by fivefold.
As a result, the new materials can be tuned to a larger number of colors than previously made materials. Indeed, North Carolina State's Velev, who works on materials that change color in response to electronic signals, says he knows of no other material capable of taking on such a wide range of colors.
The Riverside researchers found that processing the materials at high temperatures ensured that the 10-nanometer particles formed with a crystalline atomic structure. It also caused the particles to group together to form similarly sized clusters. In contrast, more commonly used room-temperature synthesis results in particles that form irregular agglomerations. The uniformity of the clusters and the crystallinity of the particles seem to improve the magnetic response of the materials, Yin says, although he and his colleagues are still looking into the underlying mechanisms involved.
The materials can switch colors at a rate of twice a second, which is still too slow for use in TVs and computer monitors. Yin hopes to increase switching speeds still more by using smaller amounts of material, perhaps in microscopic capsules. Such small amounts will make it easier to present a uniform magnetic field to the entire sample, potentially aiding the rearrangement of the clusters. Also, such microcapsules could be arranged to form pixels in a display, as is done now with E-Ink, a type of electronic paper used in some electronic book readers and a cell phones. (See "A Good Read.")
But even with faster speeds, Yin doesn't expect the materials to replace current computer-monitor technology. Rather, he has his sights set on larger-scale applications that would take advantage of the low cost of the materials. Examples could include posters that can be rewritten but don't have to change as fast as displays of video.
One significant drawback of the current materials is that they would need a constant power supply to preserve the magnetic field and hold the microcapsules at a set color. Yin's next step is to develop a version of the materials that remains stable after their color is changed--that is, until they're switched to a new color. If this is possible, then a poster could be printed with something like the read-write head on a hard drive, Yin says. It would preserve the image until it's rewritten with another pass of the print head, using no power in between.
"At this stage it's fun to play with," Velev says. "Maybe at later stages it could be used for some decorative purpose, such as paint that changes color, or some new types of labels or display boards. Right now it's a beautiful piece of research."
