Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the electrode active site based on microscope observations instead of the simplified and idealized atomic structures employed in previous studies. This better understanding of how the structures in the cells affect the reactions could give clues on ways to improve performance and durability in future devices.
A World-first study by Monash University, published in Nature Communications, has discovered a technique for creating stronger, lightweight magnesium alloys. This finding could be of significant benefit to the automobile and aerospace industries.
Mothers living near more intense oil and gas development activity have a 40-70% higher chance of having children with congenital heart defects (CHDs) compared to those living in areas of less intense activity, according to a new study from researchers at the Colorado School of Public Health.
The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. Now researchers from the University of Houston and the Massachusetts Institute of Technology have reported the discovery of a new material that works efficiently at room temperature while requiring almost no costly tellurium, a major component of the current state-of-the-art material.
The molten rock that feeds volcanoes can be stored in the Earth's crust for as long as a thousand years, a result which may help with volcanic hazard management and better forecasting of when eruptions might occur.
It's a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a study in the journal eLife. These red algal species, known as Cyanidiales, also stole many genes that allow them to absorb and process different sources of carbon in the environment to provide additional sources of energy and supplement their photosynthetic lifestyle.
Imagine powering your devices by walking. With technology recently developed by researchers at the Chinese University of Hong Kong and described in Applied Physics Letters, that possibility might not be far out of reach. An energy harvester is attached to the wearer's knee and can generate 1.6 microwatts of power while the wearer walks without any increase in effort. The energy is enough to power small electronics like health monitoring equipment and GPS devices.
Earthquakes are getting deeper at the same rate as the wastewater sinks.
The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Now an international team of researchers led by Nasser Najibi and Naresh Devineni at The City College of New York is offering a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding.
Southwest Research Institute and The University of Texas at San Antonio are collaborating to acquire data for a computational model for supercritical carbon dioxide (sCO2) energy generation. The work, led by Jacob Delimont of SwRI's Mechanical Engineering Division and Christopher Combs of UTSA's College of Engineering, is supported by a $125,000 grant from the Connecting through Research Partnerships (Connect) Program.
