Reversal speeds creation of important molecule

Rice's K.C. Nicolaou lab makes synthesis of halichondrin B more efficient

02-Jul-2021

The story of halichondrin B, an inspirational molecule obtained from a marine creature, goes back to the molecule's discovery in an ocean sponge in 1986. Though it has been replicated in the laboratory several times before, new work by Rice University chemists could make halichondrin B and its ...

New quantum material discovered

A research team came across a surprising form of "quantum criticality". This could lead to a design concept for new materials

26-May-2021

In everyday life, phase transitions usually have to do with temperature changes – for example, when an ice cube gets warmer and melts. But there are also different kinds of phase transitions, depending on other parameters such as magnetic field. In order to understand the quantum properties of ...

Cerium sidelines silver to make drug precursor

Rice University lab's process simplifies fluoroketone synthesis

02-Mar-2021

Save your silver! It's better used for jewelry than as a catalyst for drugs. Rice University scientists have developed a greatly simplified method to make fluoroketones, precursors for drug design and manufacture that typically require a silver catalyst. Rice chemist Julian West and graduate ...

A little soap simplifies making 2D nanoflakes

Rice lab's experiments refine processing of hexagonal boron nitride

29-Jan-2021

Just a little soap helps clean up the challenging process of preparing two-dimensional hexagonal boron nitride (hBN). Rice University chemists have found a way to get the maximum amount of quality 2D hBN nanosheets from its natural bulk form by processing it with surfactant (aka soap) and water. ...

Flash graphene rocks strategy for plastic waste

Rice University lab detours potential environmental hazard into useful material

03-Nov-2020

Plastic waste comes back in black as pristine graphene, thanks to ACDC. That's what Rice University scientists call the process they employed to make efficient use of waste plastic that would otherwise add to the planet's environmental woes. In this instance, the lab of Rice chemist James Tour ...

Scientists find path to nanodiamond from graphene

A spot of pressure enables chemical conversion to hardened 2D material

02-Nov-2020

Marrying two layers of graphene is an easy route to the blissful formation of nanoscale diamond, but sometimes thicker is better. While it may only take a bit of heat to turn a treated bilayer of the ultrathin material into a cubic lattice of diamane, a bit of pressure in just the right place can ...

Shape matters for light-activated nanocatalysts

Pointed tips on aluminum 'octopods' increase catalytic reactivity

23-Sep-2020

Points matter when designing nanoparticles that drive important chemical reactions using the power of light. Researchers at Rice University's Laboratory for Nanophotonics (LANP) have long known that a nanoparticle's shape affects how it interacts with light, and their latest study shows how shape ...

Boron nitride destroys PFAS 'forever' chemicals PFOA, GenX

Pollutant-destroying properties surprise Rice engineer: ‘It’s not supposed to work’

10-Jul-2020

Rice University chemical engineers found an efficient catalyst for destroying PFAS "forever" chemicals where they least expected. "It was the control," said Rice Professor Michael Wong, referring to the part of a scientific experiment where researchers don't expect surprises. The control group is ...

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 ...

Double-walled nanotubes have electro-optical advantages

01-Apr-2020

One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when ...
