Polyurethane is a polymer formed by reaction of isocyanate with a polyol. These polymers cover an extremely wide range of stiffness, hardness, and density, and are commonly used to manufacture high-resilience foam seating, rigid foam insulation panels, foam seats and … Weiterlesen …
Fuel cells are devices that generate electricity by harnessing chemical potential energy. All fuel cells possess the same basic configuration, two electrodes (more accurately, a cathode and anode) and electrolyte, however, differ in terms of reactions taking place. Many experts … Weiterlesen …
Despite all the discussions surrounding plastic waste and its detriment to the environment, we continue to use more and more plastic every year. Of more than 200 million tonnes of plastics produced worldwide annually, 6 to 26 million tonnes end … Weiterlesen …
Printed electronics are currently receiving a lot of attention. They promise to develop fields of applications for electronics that were previously not or only partially accessible to conventional electronics. New developments in printed electronics are emerging, for example, in applications … Weiterlesen …
Flexible electronic devices are becoming more and more popular, with examples of TVs, computers, and smartphones that can be folded or rolled, and reports of wearable micro-devices or sensors that can be integrated into our clothes, already hitting the market. … Weiterlesen …
The automotive industry is facing major challenges, one of which is reducing fuel consumption and thereby increasing the range of electric cars. While this problem seemingly cannot be solved with a blanket solution, design engineers are increasingly looking to lightweight … Weiterlesen …
3D displays are state-of -the-art technology. For example, we can think of stereo displays capable of conveying depth perception to the viewer. In nature, we can consider the cephalopods – a class of marines animals, which includes the squid and octopus – … Weiterlesen …
In 2018, around 5.6 million electric vehicles were globally registered, which exceeded more than two million vehicles registered in the previous year. This amount has increased more than tenfold since 2013, but the current limitations of batteries still hinders many … Weiterlesen …
Long before the invention of artificial refrigeration, making ice by nocturnal cooling was common. Here, an apparatus consisting of a ceramic tray with a thin layer of water was placed outdoors, and on a clear night, ice would form as … Weiterlesen …
Graphene is a one atom-thick layer of carbon with two dimensional properties. It is a transparent and flexible conductor, and thanks to its extraordinary mechanical strength and excellent conducting properties, it is one of the most promising materials for an … Weiterlesen …
