A serendipitous observation in a Chemical Engineering lab at Penn Engineering has led to a surprising discovery: a new class of nanostructured materials that can pull water from the air, collect it in pores and release it onto surfaces without the need for any external energy. The research, published in Science Advances, was conducted by an interdisciplinary team, including Daeyeon Lee, Russell Pearce and Elizabeth Crimian Heuer Professor in Chemical and Biomolecular Engineering (CBE), Amish Patel, Professor in CBE, Baekmin Kim, a postdoctoral scholar in Lee’s lab and first author, and Stefan Guldin, Professor in Complex Soft Matter at the Technical University of Munich. Their work describes a material that could open the door to new ways to collect water from the air in arid regions and devices that cool electronics or buildings using the power of evaporation.

Large shifts in UV radiation at Lake Tahoe are associated with wet and dry climate extremes, finds a UC Davis study.

New research from the University of Chicago shows that dentine, the inner layer of teeth that transmits sensory information to nerves inside the pulp, first evolved as sensory tissue in the armored exoskeletons of ancient fish.

SeaSplat is an image-analysis tool that cuts through the ocean’s optical effects to generate images of underwater environments reveal an ocean scene’s true colors. Researchers paired the color-correcting tool with a computational model that converts images of a scene into a three-dimensional underwater “world” that can be explored virtually. 

Scientists studying a promising quantum material have stumbled upon a surprise: within its crystal structure, the material naturally forms one of the world’s thinnest semiconductor junctions—a building block of most modern electronics. The junction is just 3.3 nanometers thick, about 25,000 times thinner than a sheet of paper.

As global warming alters ecosystems, the need to predict the reorganization of Earth’s biodiversity has become urgent. New research, published in the Proceedings of the National Academy of Sciences of the United States of America May 20, suggests that neglecting the ecological differences between male and female plants can lead to inaccurate biodiversity forecasts. The study led by Jacob Moutouama, a postdoctoral research associate at Rice University and lead author, highlights the need to refine biodiversity forecasts to account for the sex-specific responses to Earth’s rapidly changing climate.

Using synchrotron X-ray nanotomography with detailed 3D imaging and in-situ mechanical testing, researchers are peering inside shark skeletons at the nanoscale, revealing a microscopic “sharkitecture” that helps these ancient apex predators withstand extreme physical demands of constant motion. After hundreds of millions of years of evolution, scientists can now finally see how shark cartilage works at the nanoscale – and learn from them.

Artificial intelligence tools can assist emergency room physicians in accurately predicting disease but only for patients with typical symptoms, West Virginia University scientists have found.

A universal method of micro-patterning solution-processed materials is highly desired by industry to enable the integration of these materials with optoelectronic devices. A team at the University of Washington demonstrated a dry photolithographic lift-off method for high-resolution patterning (~1 µm diameter) of quantum dots (QDs). They also achieved full-scale processing on a 100 mm wafer and multi-color integration of two different varieties of QDs. This method paves a way towards realization of high-resolution micro-LED displays.
