Conventional electroluminescent (EL) foils can be bent up to a certain degree only and can be applied easily onto flat surfaces. The new process allows for the direct printing of electroluminescent layers onto three-dimensional components. Such EL components might be used to enhance safety in buildings in case of power failures. Other potential applications are displays and watches or the creative design of rooms.
A team of researchers has unveiled a new method of controlling the shapes of structures—so called mesoatoms—formed by microdroplets placed inside another drop. The work increases the possibilities of controlling the processes of self-organization of matter. During their research, the scientists also managed for the first time to observe the formation of microdroplet structures with unexpected shapes.
Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that may quicken the development of fusion energy. They found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically. High heat and pressure are crucial to fusion...
A wearable device will provide real-time data analysis of fluid loss during exercise to enhance the performance of fitness enthusiasts and elite athletes. The innovative transdermal sensor is a small device that attaches to the body to analyze electrolytes in sweat, with Bluetooth technology used to send the data back to a smartphone—allowing the user to rehydrate properly and maintain optimum performance
Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework (MOF), a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. This work builds on previous research in which the Sandia team realized electrical conductivity in MOFs by infiltrating the pores with TCNQ.
Non-metallic mesoporous structures have already demonstrated potential for applications in gas storage, separation, catalysis, ion-exchange, sensing, polymerization and drug delivery. Metal mesoporous films could have fascinating and useful optical properties, as they are effectively the inverse of nanoparticle arrays. Researchers have demonstrated a simple approach for producing metal films with regular tuneable mesopores.
The rapid evolution of gadgets has brought us an impressive array of "smart" products from phones to tablets, and now watches and glasses. But they still haven't broken free from their rigid form. Now, scientists are reporting ia new step toward bendable electronics. They have developed the first light-emitting, transparent and flexible paper out of environmentally friendly materials via a simple, suction-filtration method.
Some major trucking companies are turning to natural gas to fuel their fleets, and to earn “green” credit among customers. But celebrating lower emissions could be premature. Researchers have found that converting heavy-duty trucks to run on natural gas could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel’s supply chain.
Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in electronics, energy, the environment and even medicine.
Although scientists are increasingly using pint-size satellites sometimes no larger than a loaf of bread to gather data from low-Earth orbit, they have yet to apply the less-expensive small-satellite technology to observe physical phenomena far from terra firma. Jaime Esper, a technologist at NASA's Goddard Space Flight Center in Greenbelt, Md., however, is advancing a CubeSat concept that would give scientists that capability.
Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice Univ. are beginning to understand why. By modeling the average mollusk’s mobile habitat, they are learning how shells stand up to extraordinary pressures at the bottom of the sea.
Researchers have found a way to couple the properties of different 2-D materials to provide an exceptional degree of control over light waves. They say this has the potential to lead to new kinds of light detection, thermal management systems and high-resolution imaging devices.
A new federal plan aims to reverse America's declining honeybee and monarch butterfly populations by making millions of acres of federal land more bee-friendly, spending millions of dollars more on research and considering the use of fewer pesticides. While putting different type of landscapes along highways, federal housing projects and elsewhere may not sound like much in terms of action.
GE Launches the Next Evolution of Wind Energy Making Renewables More Efficient, Economic: the Digital Wind FarmMay 19, 2015 11:49 am | by GE | Comments
GE has announced the launch of its Digital Wind Farm, a dynamic, connected and adaptable wind energy ecosystem that pairs world-class turbines with the digital infrastructure for the wind industry. The technology boosts a wind farm’s energy production by up to 20 percent and could help generate up to an estimated $50 billion of value for the wind industry.
Modern medicine relies on optical fibers to cauterize unhealthy veins in a minimally invasive way. Now, Fraunhofer researchers have developed a laser processing method that facilitates automated series manufacture of these fibers at a much finer quality than ever before. The scientists presented a fiber probe prototype manufactured using the new technique at the measurement fair SENSOR+TEST 2015 in Nuremberg.
