The last years gave rise to the investigation of several organic semiconductor materials. They promise easier and cheaper fabrication without the need for seldom elements at very good electrical quality. This allows for large-scale production, even via printing processes. Inherent … Weiterlesen …

Tel Aviv University researchers have printed the world’s first 3D vascularised engineered heart using a patient’s own cells and biological materials. Until now, scientists in regenerative medicine have been successful in printing only simple tissues without blood vessels. “This is the first time … Weiterlesen …

Metals that are liquids at room temperature, such as gallium and certain alloys, have unique properties including high conductivity, low melting point, and high deformability. These properties make them attractive for use in soft robots and flexible electronics. By adding … Weiterlesen …

Theoretically, to power cities and cars, “you need so much hydrogen it is not conceivable to use purified water,” says Hongjie Dai, professor in chemistry in Stanford’s School of Humanities and Sciences. “We barely have enough water for our current needs … Weiterlesen …

Access to clean water remains one of the biggest challenges facing humankind. A breakthrough by engineers at the University of Texas in Austin may offer a new solution through solar-powered technology that absorbs moisture from the air and returns it as clean, usable water. … Weiterlesen …

In many fields, from health to food quality control, environmental monitoring and technical applications, there is a growing demand for responsive sensors, which show fast and simple changes in the presence of specific molecules. Water is among the most common … Weiterlesen …

In the case of mechanical damage to a battery pack in an e-car, a high current initially flows through the affected region and the temperature rises locally. In conventional battery solutions, the cell is affected directly, with its material expanding … Weiterlesen …

Last August, a team of scientists hiked deep into in the wilderness of Yellowstone National Park to hunt for life. In the Heart Lake Geyser Basin area, the team found four pristine pools of hot water. They carefully left a … Weiterlesen …

By their very nature, sunlight and wind, as renewable sources of energy, fluctuate in intensity. Intelligent power grids and energy storage systems are essential in order to compensate for these fluctuations and ensure a secure supply of power from renewable … Weiterlesen …

Chicken eggs are used worldwide in large quantities in the food, pharmaceutical, and manufacturing industries, and for household purposes. However, after the egg is used, the shells are discarded and disposed of as bio-waste in landfills. The shell consists of … Weiterlesen …
