2D sandwich sees molecules with clarity

Researchers adapt 2D 'sandwich' for surface-enhanced Raman spectroscopy

18-May-2020

A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules. Tests at Rice University's Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of ...

Shaping light lets 2D microscopes capture 4D data

Invention adds new dimension to fluorescent microscopy

20-Feb-2019

Rice University researchers have added a new dimension to their breakthrough technique that expands the capabilities of standard laboratory microscopes. Two years ago, the Rice lab of chemist Christy Landes introduced super temporal resolution microscopy, a technique that allowed researchers to ...

Light triggers gold in unexpected way

Mechanism to control output of a nanoscale antenna

04-Dec-2018

Rice University researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles. They weren't looking for it, but students in the lab of Rice chemist Stephan Link found that exciting the microscopic particles just right produced ...

Iron outperforms gadolinium as MRI contrast agent

24-Aug-2018

Rice University nanoscientists have demonstrated a method for loading iron inside nanoparticles to create MRI contrast agents that outperform gadolinium chelates, the mainstay contrast agent that is facing increased scrutiny due to potential safety concerns. "The possibility of eliminating ...

Particles pull last drops of oil from well water

Nanoscale solution to ‘produced water’ problem

17-Aug-2018

Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...

Social context matters in spread of disease

09-May-2018

"Patient zero" isn't entirely to blame when an infection takes root in a population. According to Rice University scientists, social context in the community has a lot to do with how a disease spreads. Rice researchers who study fruit flies found that the ratio of females to males as well as the ...

Rice U. sleuths find metal in 'metal-free' catalysts

28-Feb-2018

Detective work by Rice University chemists has defined a deception in graphene catalysts that, until now, has defied description. Graphene has been widely tested as a replacement for expensive platinum in applications like fuel cells, where the material catalyzes the oxygen reduction reaction ...

Nature's toughest substances decoded

05-Dec-2017

How a material breaks may be the most important property to consider when designing layered composites that mimic those found in nature. A method by Rice University engineers decodes the interactions between materials and the structures they form and can help maximize their strength, toughness, ...

New test opens path for better 2-D catalysts

09-Oct-2017

Rice University researchers have taken a deep look into atom-thick catalysts that produce hydrogen to see precisely where it's coming from. Their findings could accelerate the development of 2-D materials for energy applications, such as fuel cells. The Rice lab of materials scientist Jun Lou, ...

Adding to theory about Huntington's mechanism

12-Apr-2017

Rice University researchers are starting to understand how protein fragments influence the fiber aggregation suspected as a cause of Huntington's disease. In their computer simulations, Rice bioscientist Peter Wolynes and graduate student Mingchen Chen show that the N-terminal sequence in ...
