Scientific Lasers Deliver Ease of Use, Greater Reliability
May 1, 2018 — Ultrafast lasers are the dominant laser source for scientific applications. Two key technical trends are emerging that support several diverse applications. The first development is the emergence of ytterbium fiber (Yb-fiber) as a reliable alternative gain medium to the traditionally employed titanium:sapphire (Ti:sapphire). For the high-repetition-rate oscillators needed in multiphoton microscopy, both materials provide excellent performance.
Dual-Catalyst Technique Allows Better Control of Molecules
MADISON, Wis., April 24, 2014 — Chemical reactions usually happen on their own terms. But now, researchers from the University of Wisconsin-Madison have discovered a way to create molecules with controlled chirality using sunlight as one of two catalysts.
Piece of energy puzzle could lead to better OLEDs and solar cells
TORONTO – Scientists have put together a couple more pieces of the puzzle to explain how energy levels align in a critical group of advanced materials, which could have implications for developing sustainable technologies such as dye-sensitized solar cells...
Bilayered nanocrystals could bring cleaner energy
BERKELEY, Calif. – New bilayered nanocrystals made of metal-metal oxide that feature multiple catalytic sites on nanocrystal interfaces could mean big things for industrial catalysis and for clean green energy technologies such as artificial photosynthesis. For the...
Getting to the electrochemical core makes for better materials science
NOTTINGHAM, UK – Scientists have, for the first time, probed the inner core of electrochemical interactions as they happen. The application of this new spectroelectrochemistry technique could lead to a more efficient and more intelligent design of new materials to...
