Plant/polymer composite materials have been fabricated. These  composite  materials  are  stimuli responsive  and  can  undergo  shape-shifting   behavior   in   response   to temperature or light. 

Organic semiconductor materials have shown promise in recent years for use in low-cost electronics applications such as photovoltaics, chemical sensors, and flat-panel displays. In particular, pentacene thin films have been shown to exhibit high a large field-effect mobility on the order of 1 cm2/Vs, which is sufficient for organic thin-film transistors (TFTs) for displays.

Rules for the creation of alloys within the family of Heusler compounds, which are ordered compounds formed between metals, have been broadly formulated. Heusler compounds are important functional materials, used for their magnetic and thermoelectric properties. These rules will help in designing new materials with optimized functionality. The results directly support the goals of IRG-1 Magnetic Intermetallic Mesostructures since the controlled formation of single-phase and mesostructured magnetic Heusler materials is central to the project.

New lithium-ion transporting polymers, suitable for use as solid electrolytes in lithium ion batteries have been developed based on controlling the dielectric properties of polymers and details of the polymer architecture. Many lithium-transporting polymers, which could play a central role in the future of solid-state lithium batteries, suffer from poor lithium conductivity, even if the total conductivity could be high due to the counterions moving. MRSEC IRG-2 researchers have devised strategies to ensure that it is the lithium that moves, making these materials useful. 

The key protein that helps bloodworms form copper-based mineral composites to make very strong jaws has been identified along with the several functions that it serves.

Novel chemical reactions enable scalable and atom-economic synthesis of two-dimensional metal carbides and nitrides (MXenes). These directly synthesized MXenes from the University of Chicago show excellent energy storage capacity for Li-ion intercalation.

Graduate Students for Diversity in Science is composed of an interdisciplinary group of young scientists at the University of California, Santa Barbara (UCSB). The cornerstone of the group lies in its recognition of the cultural heritage and diversity of many exceptional scientists who have set foundations through research, service, and leadership in their respective disciplines and across many boundaries. GSDS aims to promote participation in the science, technology, engineering and math (STEM) fields and foster an inclusive atmosphere that celebrates diversity.

A collaboration between the de Pablo, Rowan and Jaeger groups at the University of Chicago developed a novel class of suspensions with stimuli-responsive polymer particles to be able to transition reversibly between liquid to solid behavior in response to temperature,

Electrons in topological materials behave like massless particles (called Weyl fermions). They are either right- or left-handed (the spins are locked parallel or antiparallel to their velocity). In parallel applied electric and magnetic fields, one population grows while the other shrinks. This leads to a new kind of electrical current called an “axial” current. The Princeton MRSEC group has observed this new effect (called the chiral anomaly) in two distinct topological metals, Na3Bi and GdPtBi (1,2).
