Place something in the sun, and it will heat up. The use of a reflective window shade in a car is a common way to prevent the interior from getting hot due to incident sunshine. Similarly, a building’s light-colored roof heats up less than a dark roof, but both can get much hotter than ambient air temperature.

At a market size of $12 billion, additive manufacturing holds tremendous promise for industrial applications. On-demand production saves both time and money and can be more efficient than some traditional forms of manufacturing. Currently, however, 3D printing comprises less than 0.1% of all manufacturing, due in part to the finite number of printable materials that are viable for industrial use.

The world is in desperate need of technologies that can quickly and cost-effectively abate the 5-Gt annual CO2 emissions of heavy-duty sectors, such as on-road freight transportation and off-highway equipment. While electrification is helping to curb tailpipe emissions of light-duty and short-range transportation, large-scale deployment in heavy-duty sectors is still decades away. These industries need solutions today that can bridge the gap to a decarbonized future.

Magnesium metal is a critical infrastructure material commonly associated with structural lightweighting in automotive, aircraft, and portable electronic segments. Currently, China uses the silicothermic Pidgeon process to produce 85% of global Mg metal. This crude process, which emits on average 28 kg CO2eq/kg Mg, is inefficient and polluting, but its low labor and energy costs translate to the lowest metal price. “Although it supported the survival and development of the global magnesium industry, the Pidgeon process has no future due to its carbon footprint,” says Alexandru Rosu, the business development lead for private equity investment firm Amerocap LLC’s Romanian magnesium project.

The global shortage of transplantable organs has long been recognized as a significant challenge in the organ transplant supply chain. Only 10% of the worldwide need for organ transplantation is being met. On average, only 35% of all organs authorized for transplant are actually transplanted. Among the large solid organs, the lungs, intestine, and heart have the lowest utilization, partially due to their very short preservation times.
