A collaboration between the University of Chicago MRSEC groups of Jaeger, Patel, and Rowan showed that the complex modulus of a dense suspension of microparticles can be increased exponentially over several orders of magnitude by applying interval training during oscillatory shear, leading to a structural memory.
The COVID-19 pandemic highlights the need for platform technologies enabling rapid development of vaccines for emerging viral diseases. The current vaccines target the SARS-CoV-2 spike (S) protein and thus far have shown tremendous efficacy. However, the need for cold-chain distribution, a prime-boost administration schedule, and the emergence of variants of concern (VOCs) call for diligence in novel SARS-CoV-2 vaccine approaches.
The UCSD MRSEC RIMSE Summer Schools prepare trainees to engage in research, in MRSEC labs and within UCSD at large. The program streamlines high school students, undergraduate students (with a particular focus on transfer students), REU students, and incoming graduate students into research programs in the domains covered by the two IRGs.
This work represents the first study to establish fluoride as a universal amorphizing agent in the indium oxide system, and by inference, may play a similar role in related oxide semiconductor materials.
Lattice defects play an important role in determining the optical and electrical properties of monolayer semiconductors such as MoS2. Although the structures of various defects in monolayer MoS2 are well studied, little is known about the properties of the fluorescent defect species and their interaction with molecular adsorbates.
The Harvard MRSEC provides a vibrant culture of entrepreneurship and several recent Ph.D. students supported by Center IRGs and seed projects have co-founded new companies.
A team at the Harvard MRSEC led by Bertoldi and Aizenberg has developed an approach to achieve a diverse trajectories from a single-material system via self-regulation: when a photoresponsive liquid crystal elastomeric pillar with mesogen alignment is exposed to light, it ‘dances’ dynamically as light initiates a traveling order-to-disorder transition front that twists and bends via opto-chemo-mechanical feedback.
UD CHARM and Princeton’s PCCM coordinated with the Chicago MRSEC to host three virtual events (Soft Matter for All, Rising Stars, and a Professional Development Workshop) to highlight early career, high-impact research and ignite discussion for graduate students and postdocs pursuing academic and non-academic career paths.
Experimental studies combined with theoretical calculations of spin dynamics across a wide frequency range from ~10 GHz to several THz in a novel amorphous ferromagnet (FM)/3D topological insulator (TI) (FeGaB/BiSb) system that is scalable and provides a promising platform for spin-electronic devices.
Producing self-assembled structures of prescribed limited size and shape is a major challenge in nanoscience. A major achievement of the MRSEC was to elucidate a new chirality-based mechanism that leads to self-limiting assembly of colloidal rafts.
