Retired electric vehicle batteries could be used to store renewable energy

By: National Science Foundation

December 9, 2021 Researchers at Cornell University, partially funded by the U.S. National Science Foundation, recently published a study that outlines ways to sustainably repurpose used lithium-ion electric vehicle batteries to reduce their carbon footprint. The researchers investigated how battery chemistry, reuse and recycling influence the energy output and environmental impact of lithium-ion EV batteries. The analysis, published in Science Advances, found that the carbon footprint of a lithium-ion EV battery can be reduced by up to 17% if it is reused before being recycled. Batteries with...

Functional Soft Matter Designed using Non-Equilibrium Interfacial States of Liquid Crystals

Abstract Soft matter provides the basis of a wide range of consumer products (from skin creams to salad dressings), yet our ability to engineer dynamic interfacial phenomena that underlie the structure and function of many of these products remains primitive. This presentation will explore how liquid crystalline oils can provide new methods to study non-equilibrium states of oil-water interfaces and new designs of functional soft matter. A first example will describe surfactant-driven flows at interfaces of liquid crystals, revealing how liquid crystals enable optical characterization of the... Read more

Biofuels: A Third Act for Your Leftovers

By: KeShonna Jackson ’24

Every year, Nazih Kassem sits down to sort through heaps of data detailing the amount of organic waste, in tons, discarded by every restaurant, brewery, distillery, grocery store, farm, and school in New York State. Food waste floods our landfills, while agricultural waste, such as manure, is typically applied to fields. In either case, the waste decomposes and produces methane, a powerful greenhouse gas that traps heat in the atmosphere and contributes to global warming. Kassem, a PhD student in Biological and Environmental Engineering, believes that we can redirect organic waste and extract... Read more

Exploring novel transitions that bridge phases with distinct lattice symmetry

By: B.P. Prajwal, Jen-Yu Huang, Meera Ramaswamy, Abraham D. Stroock, Tobias Hanrath, Itai Cohen, Fernando A. Escobedo

A recently published article from the Escobedo, Stroock, Hanrath, and Cohen groups at Cornell demonstrates via simulations and a simple experimental strategy how a single monolayer of particles can be coaxed to form lattices with either hexagonal or square symmetry. The unique phase behavior observed in this work can provide a template for designing materials for speciality applications with switchable hexagonal↔square packings, e.g., to fabricate optical switches, and optical biosensors. Abstract The entropy-driven monolayer assembly of hexagonal prisms and cylinders was studied under hard... Read more

Shotgun scanning glycomutagenesis: A simple and efficient strategy for constructing and characterizing neoglycoproteins

By: Proceedings of the National Academy of Sciences of the United States of America (PNAS)

Matt DeLisa, the William L. Lewis Pressor of Engineering and Director of the Cornell Institute of Biotechnology, published a new study in the Sep. 28 issue of PNAS. The study, "Shotgun scanning glycomutagenesis: A simple and efficient strategy for constructing and characterizing neoglycoproteins," focuses on a glycoprotein engineering strategy that enables systematic investigation of the structural and functional consequences of glycan installation at every position along a protein backbone and provides a new route to bespoke glycoproteins. Asparagine-linked (N-linked) protein glycosylation... Read more
