Sustainable chemistry at the quantum level

New breakthroughs in computational quantum chemistry, hold promise for discovering catalysts that are "just right" and thousands of times faster than standard approaches

10-Aug-2020

Developing catalysts for sustainable fuel and chemical production requires a kind of Goldilocks Effect - some catalysts are too ineffective while others are too uneconomical. Catalyst testing also takes a lot of time and resources. New breakthroughs in computational quantum chemistry, however, ...

Predicting unpredictable reactions

Research paves the way for simulating catalysts under reaction conditions

11-Jun-2020

Computational catalysis, a field that simulates and accelerates the discovery of catalysts for chemicals production, has largely been limited to simulations of idealized catalyst structures that do not necessarily represent structures under realistic reaction conditions. New research from the ...

Let's do the twist

Researchers 'program' liquid crystalline elastomers to replicate complex twisting action simply with the use of light

09-Apr-2020

The twisting and bending capabilities of the human muscle system enable a varied and dynamic range of motion, from walking and running to reaching and grasping. Replicating something as seemingly simple as waving a hand in a robot, however, requires a complex series of motors, pumps, actuators ...

Carbon nanotubes show a love/hate relationship with water

14-Nov-2019

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of ...

New Partnership Expands Research into Rechargeable Battery Systems

05-Jun-2019

Energy storage influences every part of modern life, from the cell phone in your pocket to the electric car on the highway. However, seeing the chemistry of what is happening inside a battery while it is in use is indeed tricky, but it could have remarkable opportunities for identifying new ...

A catalytic flying carpet

Chemical engineering researchers develop self-powered microfluidic sheet that wraps, flaps and creeps

04-Jan-2019

The "magic carpet" featured in tales from "One Thousand and One Nights" to Disney's "Aladdin" captures the imagination not only because it can fly, but because it can also wave, flap, and alter its shape to serve its riders. With that inspiration, and the assistance of catalytic chemical ...

A transparent flexible material of silk and nanotubes

Nanotube interactions with silk fibroins - key to flexible, degradable electronics

02-Nov-2018

The silk fibers produced by Bombyx mori, the domestic silkworm, has been prized for millennia as a strong yet lightweight and luxurious material. Although synthetic polymers like nylon and polyester are less costly, they do not compare to silk's natural qualities and mechanical properties. And ...

New glass for solar cells and LEDs

14-Dec-2017

Using nanoscale grass-like structures, researchers at the University of Pittsburgh , Pennsylvania have created glass that lets through a large amount of light while appearing hazy. This is the first time that glass has been made with such high levels of haze and light transmittance at the same ...

Printing a better actuator, actually

15-Nov-2017

One technology uses magnetic fields to generate mechanical work. The other enhances the magnetic properties of 3D-printed materials. Combined, they could lead to efficient, economical production of magnetic actuators used in everything from sensors, robotics, and mechanical devices to power ...

In search of a greener cleaner

22-Sep-2017

Molecular chelating agents are used in many areas ranging from laundry detergents to paper pulp processing to precious metal refining. However, some chelating agents, especially the most effective ones, do not degrade in nature and may pollute the environment. With support from the National ...
