University of Oregon scientists dissociate water apart efficiently with new catalysts
Using a new approach, they were able to study and improve the water-dissociation reaction that rips apart water molecules in membrane-based electrochemical reactors
08-Jul-2020
University of Oregon chemists have made substantial gains in enhancing the catalytic water dissociation reaction in electrochemical reactors, called bipolar membrane electrolyzers, to more efficiently rip apart water molecules into positively charged protons and negatively charged hydroxide ...
How frogs' tongues become sticky
Research team investigates the surface chemistry of the frog sticky-tongue mechanism
29-Nov-2018
Frogs' capture their preywiththestickymucuscoveringtheir tongues, but this mucusisn't inherently adhesive.Frogmucus is thought to be pressure-sensitive, with tongue retraction strain triggering adhesion. A research team from Oregan State University, Aarhus University and Kiel University ...
New class of hydrogen sulfide donor molecules created
03-Jan-2017
Molecules with the potential to deliver healing power to stressed cells - such as those involved in heart attacks - have been created by University of Oregon researchers. The research - done at a cellular level in the lab and far from medical reality - involves the design of organic molecules ...
Chemists build a new, stable open-shell molecule
10-Jun-2016
University of Oregon chemists have synthesized a stable and long-lasting carbon-based molecule that, they say, potentially could be applicable in solar cells and electronic devices. The molecule changes its bonding patterns to a magnetic biradical state when heated; it then returns to a fully ...
New approach for 'nanohoops' could energize future devices
13-Oct-2015
When Ramesh Jasti began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes being developed for use in electronics or optical devices. He quickly realized, however, that his technique might also roll solo. In a new paper, Jasti and five University ...
UO-industry collaboration points to improved nanomaterials
University of Oregon microscope puts spotlight on the surface structure of quantum dots for designing new solar devices
02-Dec-2014
A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of University of Oregon and industry researchers. To increase light-harvesting efficiency of solar cells beyond silicon's limit of about 29 ...
New insights on controlling nanoparticle stability
New findings could enhance stabilizing or destabilizing nanoparticles, depending on their uses
11-Dec-2013
University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is ...
New light on solar water-splitting process
Fundamental discovery could speed development of efficient semiconductor-catalytic junctions
04-Dec-2013
With the help of a new method called "dual-electrode photoelectrochemistry," University of Oregon scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in water-splitting ...
Aluminum should yield new technological advances
31-Oct-2013
Researchers at Oregon State University and the University of Oregon announced a scientific advance that has eluded researchers for more than 100 years – a platform to fully study and understand the aqueous chemistry of aluminum, one of the world's most important metals. The findings, reported in ...
Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst
Basic University of Oregon research shows promise in efforts to get hydrogen fuel from sunlight and water
22-Mar-2013
University of Oregon chemists say that ultra-thin films of nickel and iron oxides made through a solution synthesis process are promising catalysts to combine with semiconductors to make devices that capture sunlight and convert water into hydrogen and oxygen gases. Researchers in the Solar ...
