New Jersey Institute of Technology biologist Xiaonan Tai has received a National Science Foundation CAREER Award to investigate how landscape positions determine forest fate during extreme heat and drought — a factor that could help explain why some forests perish while others survive.

The CAREER Award, among NSF’s most prestigious honors for junior faculty, includes a grant of $1,162,914 to support Tai’s project, “Unveiling the Role of Hillslope Hydrology in Mediating Ecosystem Response to Drought,” over the next five years.

Researchers at Hokkaido University and Duke University have developed a hydrogel that heals and strengthens itself as it is overloaded and damaged. The proof-of-concept demonstration could lead to improved performance for situations where soft but durable materials are required, such as load-bearing connections and joints within machines, robots and even people.

A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self-repeating patterns that occur on different length scales and can be seen in nature in a variety of settings, including snowflakes, ferns, and coastlines. A quantum version of a fractal pattern, known as “Hofstadter’s butterfly,” has long been predicted, but the new study marks the first time it has been directly observed experimentally in a real material. This research paves the way toward understanding how interactions among electrons, which were left out of the theory originally proposed in 1976, give rise to new features in these quantum fractals. 

The study was made possible by a recent breakthrough in materials engineering, which involved stacking and twisting two sheets of carbon atoms to create a pattern of electrons that resembles a common French textile known as a moiré design. 

New double network hydrogel technology features automated self-strengthening that rapidly activates upon deformation of its polymer network.
