Advancements in a fuel cell technology powered by solid carbon could make electricity generation from coal and biomass cleaner and more efficient, according to a paper published this week. Innovations in the anode, the electrolyte and the fuel allow the fuel cell to utilize more carbon, operate at lower temperatures and show higher maximum power densities than earlier direct carbon fuel cells (DCFCs). The results appear in this week's edition of Advanced Materials.
A team of scientists from Siberian Federal University (SFU) and their colleagues from Novosibirsk and the Netherlands modeled the process of coal burning in HPP boilers and found out which type of fuel produced less harmful emissions. The study was published in Fuel journal.
Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.
Plastics are often derived from petroleum, contributing to reliance on fossil fuels and driving harmful greenhouse gas emissions. To change that, Great Lakes Bioenergy Research Center (GLBRC) scientists are trying to take the pliable nature of plastic in another direction, developing new and renewable ways of creating plastics from biomass.
New research shows that the natural environment has a powerful effect on promoting positive body image -- and you don't even have to set foot outdoors to experience the benefits.
The nominal cell operating life of perovskite solar cells is strongly influenced by their inner architecture.This was shown by two scientists at the Helmholtz-Zentrum Berlin and the Technical University of Munich. They combined experiments with numerical simulations in order to explain this observation.
You wouldn't use the same knife to cut through a thick steak as you would to slice an angel food cake, right? Although that may be a ridiculous comparison, the same principle holds true when harvesting various crops. One blade doesn't slice all. Researchers at the University of Illinois tested four blades to find the one that most efficiently cuts sugarcane.
Reported in Science Robotics, a new design, the milliDelta robot, developed by Robert Wood's team at Harvard's Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS) integrates their microfabrication technique with high-performance composite materials that can incorporate flexural joints and bending actuators, the milliDelta can operate with high speed, force, and micrometer precision, which make it compatible with a range of micromanipulation tasks in manufacturing and medicine.
Better thermal insulation means lower heating costs -- but this should not be at the expense of exciting architecture. A new type of brick filled with aerogel could make thin and highly insulating walls possible in the future -- without any additional insulation layer.
Nitrogen-based synthetic fertilizer forms the backbone of the world food supply, but its manufacture requires a tremendous amount of energy. Now, computer modeling at Princeton University points to a method that could drastically cut the energy needed by using sunlight in the manufacturing process.
