BAM German Federal Institute for Materials Research & Testing in Berlin promotes industrial development by providing research and consultation on materials technology and chemical engineering. Their recent work has been in analyzing the process by which highly flammable TFE gas is ... 詳細を見る

Power electronics appear in many everyday products, including smartphones, electronic car parts, and household objects. Such devices require controlled temperature ranges, switching frequencies, and voltage levels to operate smoothly and reliably. For harsh environments, such as the ... 詳細を見る

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a ... 詳細を見る

Chip manufacturers have been adhering to Moore’s law, a law stating that the number of transistors that can be economically placed on an integrated circuit doubles every year, since 1965. As the number of transistors increases, however, the process of manufacturing integrated circuit, ... 詳細を見る

The idea of "perfect imaging", that is a resolution less than the wavelength of light producing the image, was first proposed in the mid-19th century by famed Scottish physicist James Clerk Maxwell. For the next 150 years, it was widely believed that such was impossible due to the fact ... 詳細を見る

Large electrical systems carrying high currents could pose a danger if any of their components, such as fuses and bus bars, fail. In order to increase safety and improve manufacturing, it is necessary to understand the failure mechanisms of those components. One of those components, a ... 詳細を見る

Light-emitting diodes (LEDs) offer many benefits over incandescent lighting, such as long life spans and high luminous efficiency, and they are environmentally friendly. One of the drawbacks, however, is that LEDs need to operate at the lowest possible temperatures and this must be ... 詳細を見る

Consumers of power rely on fairly stable voltages. Transformers contain tap changers which vary the ratio of secondary to primary turns by switching the point at which either the input or output circuits are connected. Changing this ratio enables stepped voltage regulation of the output. ... 詳細を見る

There are several kinds of technology that designers at Sharp Laboratories of Europe work to create. From LED lighting, displays, and microfluidic lab-on-a-chip technology, to complex energy systems used in various devices, Sharp needed a new approach to finding the best designs. COMSOL ... 詳細を見る

Stealth airplanes and ships avoid radar detection by optimizing the shape of surfaces to reflect away from the radar source or absorb its energy. Yet, if a ship or aircraft’s antenna for communication purposes is to operate properly, it cannot be completely covered up. This makes it one ... 詳細を見る
