Using this material, the researchers hope to improve heat and sound insulation, electromagnetic interference shielding and a process called jamming that has been used in robotics and materials design. When expanding to large volumes and filling spaces, microclusters become extremely lightweight with soft and adaptable boundaries.
Researchers at the University of Pennsylvania and the Korea Institute of Science and Technology (KIST) found a way to exploit these properties of bubbles to create “microbombs” that expands with heat to form “microclusters,” which fit themselves to fill their physical confinement. Because they are mostly air, they’re ultra-lightweight and can expand to fill any given space. When it comes to taking up room without adding too much weight, the bubble can’t be beat.

She refer to the clams as “solar transformers” because they are capable of absorbing bright sunlight at a very high rate and scattering it over a large surface area.

#SECRET OF THE WINGS COLORING SHEETS PROFESSIONAL#
Shu Yang, Ph.D., Professor of Materials Science and Engineering and Chemical and Biomolecular Engineering, has been admitted as a Fellow of the Royal Society of Chemistry (RSC), a professional society based in the United Kingdom with over 50,000 members worldwide. Shu Yang Elected Fellow of Royal Society of Chemistry (FRSC), June 21, 2017 Shu Yang Elected Fellow Division of Polymeric Materials Science & Engineering (PMSEF), American Chemical Society (ACS) “For dedicated service to the Division of Polymeric Materials: Science & Engineering and pioneering the synthesis and fabrication of responsive nano- and micro structured soft materials” The resulting electrode films show rapid ion diffusion in thick films, retaining almost 100 % of the capacitance after 20,000 cycles of galvanostatic cycling at a rate of 20 A/g, and nearly thickness-independent (up to 200 micrometers, or 0.2 mm). The method marries soft matter assembly and functional hard nanomaterials by creating a coherent and long-range ordered liquid crystal phase of 2D sheets of titanium carbide, Ti 3C 2, a member of the MXene family. Researchers at the University of Pennsylvania and Drexel University reported a novel and scalable approach to prepare electrodes from atomic thin 2D nanosheets in the vertical orientation via self-assembly (see publication in Nature). When it comes to cell phones, there are fewer things more frustrating than a short battery life.

Backed by a NSF INSPIRE grant for bold, interdisciplinary research, the duo aimed to unlock the solar-powered secrets of the giant clam. In 2014, Shu Yang, of the Materials Science and Engineering, joined School of Arts and Sciences’ biophysicist Alison Sweeney on an unusual quest.
