New PFAS removal process aims to stamp out pollution ahead of semiconductor industry growth
CHAMPAIGN, Ill. — A University of Illinois Urbana-Champaign study is the first to describe an electrochemical strategy to capture, concentrate and destroy mixtures of diverse chemicals known as PFAS — including the increasingly prevalent ultra-short-chain PFAS — from water in a single process. This new development is poised to address the growing industrial problem of […]
New study: Earthquake prediction techniques lend quick insight into strength, reliability of materials
CHAMPAIGN, Ill. — Materials scientists can now use insight from a very common mineral and well-established earthquake and avalanche statistics to quantify how hostile environmental interactions may impact the degradation and failure of materials used for advanced solar panels, geological carbon sequestration and infrastructure such as buildings, roads and bridges.
Visible light energy yields two-for-one deal when added to CO2 recycling process
CHAMPAIGN, Ill. — By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemical attribute called selectivity, opening new avenues not only for CO2 conversion but also for many other chemical reactions used in catalysis research and chemical manufacturing.
More than maps: New atlas captures the state of global river systems through human context
CHAMPAIGN, Ill. — The word “atlas,” may conjure images of giant books chock full of maps and a dizzying array of facts and figures. However, the new book “The World Atlas of Rivers, Estuaries, and Deltas” tells the story of these waterways long before human intervention and how they continue to evolve in the presence of — and often at odds with — human civilization. The new atlas is a highly visual guide to the most up-to-date research on the world’s river systems, with an emphasis on the mutual relationship between people and these vital landscapes.
Breaking open the AI black box, team finds key chemistry for solar energy and beyond
CHAMPAIGN, Ill. — Artificial intelligence is a powerful tool for researchers, but with a significant limitation: The inability to explain how it came to its decisions, a problem known as the “AI black box.” By combining AI with automated chemical synthesis and experimental validation, an interdisciplinary team of researchers at the University of Illinois Urbana-Champaign […]
NSF funds new iBioFoundry at Illinois
CHAMPAIGN, Ill. — A newly funded U.S. National Science Foundation iBioFoundry at the University of Illinois Urbana-Champaign will build on more than a decade of research at the U. of I. to integrate synthetic biology, laboratory automation and artificial intelligence to advance protein and cellular engineering. This is one of five new biofoundries to be […]
Scientists use evolution to bioengineer new pathways to sustainable energy, pharmaceuticals
CHAMPAIGN, Ill. — Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons, paving new biotechnical […]
Study tracks decades of extreme heat, cold in Upper Midwest
CHAMPAIGN, Ill. — Researchers analyzed meteorological data from nine Upper Midwest states from 1979-2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts of the Upper Midwest experienced significant upticks in the number of extreme heat days over the 40 […]
PFAS found in nearly all fish tested from four northern Illinois rivers
CHAMPAIGN, Ill. — Scientists tested nine fish species from four northern Illinois rivers for contamination with per- or polyfluoroalkyl substances, synthetic chemicals found in numerous industrial and commercial products and known to be harmful to human health. They found fish contaminated with PFAS in every one of their 15 test sites. Elevated levels of PFOS, […]
Study identifies best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals
CHAMPAIGN, Ill. — Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock — corn stover, energy sorghum, miscanthus or switchgrass — performed best in a specific region of the rainfed United States. Their study will help growers […]
Researchers clarify how soft materials fail under stress
CHAMPAIGN, Ill. — Understanding how soft materials fail under stress is critical for solving engineering challenges as disparate as pharmaceutical technology and landslide prevention. A new study linking a spectrum of soft material behaviors — previously thought to be unrelated — led researchers to identify a new parameter they call the brittility factor, which allows […]
From ‘CyberSlug’ to ‘CyberOctopus’: New AI explores, remembers, seeks novelty, overcomes obstacles
CHAMPAIGN, Ill. — By giving artificial intelligence simple associative learning rules based on the brain circuits that allow a sea slug to forage — and augmenting it with better episodic memory, like that of an octopus — scientists have built an AI that can navigate new environments, seek rewards, map landmarks and overcome obstacles. Reported […]
