Genetically engineered yeast soak up heavy metal pollution
Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This ...
Nanoparticles could spur better LEDs, invisibility cloaks
In an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices, a team of University of Michigan researchers has developed a new technique that peppers ...
Enhanced stability in the presence of water could help reduce smokestack emissions of greenhouse gases
Heat and humidity can harm materials. The conditions inside smokestacks often damage materials that could remove carbon dioxide. This is especially true for metal-organic frameworks (MOFs), which remove carbon dioxide under ...
New technique to produce more durable and longer lasting lithium-ion batteries
Lithium-ion batteries are used to power many things from mobile phones, laptops, tablets to electric cars. But they have some drawbacks, including limited energy storage, low durability and long charging time. Now, researchers ...
Discovery of how amyloids bind metal ions sheds light on protein function
Amyloids are clumps of protein fragments that stick together to form stringy fibrils such as the plaques seen in the brains of Alzheimer's patients. Many of these proteins bind to metals such as zinc, but the structure of ...
Graphene-nanotube hybrid boosts lithium metal batteries
Rice University scientists have created a rechargeable lithium metal battery with three times the capacity of commercial lithium-ion batteries by resolving something that has long stumped researchers: the dendrite problem.
Metal soaps critical in speed of deterioration of oil paintings
An oil painting is not a permanent and unchangeable object, but undergoes a very slow change in the outer and inner structure. Metal soap formation is of great importance. Joen Hermans has managed to recreate the molecular ...
Designed molecules selectively remove unwanted ions from complex solutions for energy production
Nuclear energy accounts for some 19 percent of the U.S. electrical energy supply. The waste contains materials that are difficult to remove. Scientists developed four classes of molecules, called chelators, to selectively ...
Longer-lasting pain relief with MOFs
To treat headaches, back pain or fever, most of us have reached for ibuprofen at one point or another. But we often have to take doses every four to six hours if the pain warrants it. Now scientists are working on a way to ...
