Oil and gas wastewater as dust suppressant less than ideal

At the least, wastewater from oil and gas drilling should be treated in a waste treatment facility before it is used on dirt roads to suppress dust or deice roads. At the best, affordable, nontoxic dust suppressants should be developed and used, according to a multidisciplinary team of researchers.

Self-healing material a breakthrough for bio-inspired robotics

Many natural organisms have the ability to repair themselves. Now, manufactured machines will be able to mimic this property. Researchers have created a self-healing material that spontaneously repairs itself under extreme mechanical damage.

Virtual-reality testing ground for drones

Engineers have developed a new virtual-reality training system for drones that enables a vehicle to 'see' a rich, virtual environment while flying in an empty physical space. The system, which the team has dubbed 'Flight Goggles,' could significantly reduce the number of crashes that drones experience in actual training sessions. It can also serve as a virtual testbed for any number of environments and conditions in which researchers might want to train fast-flying drones.

Impacts of windfarm construction on harbor porpoises

Scientists from Germany, Denmark and the UK have built a model tool to predict what happens to marine animals when exposed to noise from the construction and operation of wind farms at sea.

Multiple uses for empty plastic bottles during disaster relief and beyond

Powerful hurricanes and earthquakes have wreaked havoc in the United States and around the world in recent years, often leaving people stranded for months and even years without access to water, food, and shelter. A unique project seeks to provide a sustainable solution, while also considering the environment.

Simulation technique models material-aging process

Imagine if engineers could build structures with materials that do not degrade over time. Researchers have proposed a new simulation technique that could help engineers do just that.

Custom silicon microparticles dynamically reconfigure on demand

Researchers at Duke University and North Carolina State University have demonstrated the first custom semiconductor microparticles to exhibit dynamically selectable behaviors while suspended in water. The study presents the first steps toward realizing advanced applications such as artificial muscles and reconfigurable computer systems.

Taking the guesswork out of discovering new high-entropy alloys

Scientists have developed a method of computational analysis that can help predict the composition and properties of as-yet unmade high performance alloys.

A reimagined future for sustainable nanomaterials

Engineered nanomaterials hold great promise for medicine, electronics, water treatment, and other fields. But when the materials are designed without critical information about environmental impacts at the start of the process, their long-term effects could undermine those advances. A team of researchers hopes to change that.
