For every ton of ethylene created, one ton of carbon dioxide is produced. With more than 300 million tons of ethylene produced each year, the production system has a huge carbon footprint that scientists and […]

Can you design a mechanism that will trace out the shape of a heart? How about the shape of a moon, or a star? Mechanism design—the art of assembling linkages and joints to create machines […]

High-speed 3D printing has just gotten a lot faster. Researchers from Tsinghua University in China have developed a new high-speed printing technology capable of creating complex millimeter-scale objects in just 0.6 seconds. Traditional 3D printing […]

In the frantic hours following an offshore oil spill, emergency responders face a destructive decision: let the oil spread or ignite it. Once ignited, it creates an “in-situ” fire pool that stops the oil from […]

The use of solar cells, devices that can convert sunlight into electricity, has grown exponentially over the past decades. These devices are enabling the production of clean and renewable energy, which could contribute to the […]

As the global transition toward clean energy accelerates, the demand for sustainable, low-cost, and scalable energy storage technologies continues to grow. While lithium-ion batteries have dominated the market for decades, concerns over lithium resource availability […]

At first glance, few materials would seem to have less in common than metals and textiles. And yet, by manufacturing nickel-titanium alloys as a highly deformable, interwoven material, more similar to fabric than a typical […]

There’s a reason why blacksmiths fire metals before hammering them. Heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, Northwestern University engineers discovered that, […]

Metal alloys crack and fail through a mechanism called “fatigue” when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very difficult to […]
