University of Chicago Press Release

In a breakthrough for nanotechnology, researchers have discovered a new way to synthesize quantum dot nanocrystals using molten salt as a medium. Traditional methods to create these materials required organic solvents, which cannot withstand the high temperatures needed for certain semiconductor materials, particularly those combining elements from groups III and V on the periodic table. By using superheated molten sodium chloride, scientists were able to synthesize these semiconductor nanocrystals, paving the way for improved applications in fields like quantum computing, LED lighting, and solar technology.

Led by a team from the University of Chicago and collaborating institutions, including RASEI Fellows Sadegh Yazdi and Gordana Dukovic, this novel method also opens new avenues for materials science by enabling the synthesis of previously inaccessible nanocrystal compositions. The technique addresses long-standing challenges by providing a high-temperature environment without degrading the materials. Researchers hope this advance will contribute to new types of devices and materials, marking a significant expansion in the range of accessible quantum dot technologies.

POSE Fall 2024 Kickoff Workshop

POSE Fall 2024 Kickoff Workshop Daniel Morton Mon, 10/07/2024 - 16:43

Daniel Morton

In early October of 2024, RASEI hosted the kickoff workshop for POSE, a new community being brought together to address some of the most critical challenges we face to do with plastics and polymers.

Polymer Solutions for the Environment, or POSE, seeks to establish a Center that will bring together expertise around the development of a circular polymer economy.

Plastics and polymers are critical materials in the modern age, forming the building blocks of everything from electronics to packaging, but this versatility comes with a cost, namely the waste and infiltration of the environment by microplastics.

This workshop brought together thought leaders in the polymer sector, from a cross section of academic, national lab and industrial organizations. The goal was to explore how best the POSE community can build a program that complements existing efforts in the field to drive the science and policy forward.

Three areas of focus were discussed, including the development of a circular polymer economy, the development of polymers that are needed for a just clean energy transition, and the integration of the science and technology research with policy, economics and social sciences.

It was a great meeting with more than 60 participants who came together to discuss ideas, present their research and approaches, and help shape the goals and directions of this nascent community.
