Stretchable and flexible optical interference coatings by polymer multilayers
Background Antireflection coatings (“ARC’s”) minimize undesired lens flare and glare and increase transmission at the interface between an optical material and its medium. While the inorganic fluorides, oxides, and sulfides that presently comprise conventional broadband ARC’s fulfill many if not all of their required functions,...

Using additive manufacturing to produce multilayered bacterial structures that can tolerate harsh chemical treatments.
Background Bacterial biofilms—three-dimensional networks of cells entangled in an extracellular polymeric matrix composed of organic macromolecules—are platforms for sustainable nano- or biomaterials production and processing. These films can establish themselves on virtually any accessible surface, are resilient to extreme conditions,...

Methods for Preparing Porous Separators for Electrochemical Cells
Background Porous separators are applied to battery electrodes through roll-to-roll processing. The current industry-standard for polymer separators (Celgard) for lithium-ion batteries (LIB’s) involves relatively involved manufacturing. These materials, fabricated separately from LIB’s, are produced from commodity polyolefin plastics derived...

Systems and Methods for Degrading PFAS
Background Per- and polyfluoroalkyl substances (PFAS) are widely used, hard-to-break-down chemicals that are harmful to human health; they contaminate water, soil, animals, and people all over the world. PFAS removal from the environment is thus very challenging, and effective PFAS remediation is so urgently needed that the U.S. government recently...

Hydrophobic cellulose surfaces created using boronic acid functional polymers
Background Hydrophobicity is a desirable quality for many types of cellulosic materials, including paper, cotton textiles, cardboard, and wood. There are large existing markets for waterproofing fabrics and building materials that are exposed to the elements as well as emerging applications that rely on creating precise hydrophobic surface patterns...

Structurally complex compounds exhibiting diverse anticancer activity profiles
­Background Natural products have historically provided a major source of drugs and therapeutic agents; for example, about 50% of anticancer drugs and 60% of antibacterial drugs are natural products or semisynthetic derivatives thereof. Skeletal diversity and high stereochemical content are well-known attributes that endow natural products with...

Titanium Oxide-coated Lithium Niobate
Background Microring resonators are particularly suitable as integrated photonic components given their flexibility of device engineering and potential for large-scale integration, but their susceptibility to temperature fluctuation has become a major challenge for their implementation in a practical environment. The realization of lithium niobate...
