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 ...

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 ...

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 ...

Safer carbon nanomaterials, by design

08-Sep-2017

Carbon nanomaterials (CNMs) are a class of engineered nanomaterials that can be used for many environmental applications, including water treatment and contaminant sensing and remediation. While they are prized for their ability to detect, remove, or degrade contaminants in the environment, CNMs ...

Water, water, nowhere

08-May-2017

Hydrogen powered fuel cell cars, developed by almost every major car manufacturer, are ideal zero-emissions vehicles because they produce only water as exhaust. However, their reliability is limited because the fuel cell relies upon a membrane that only functions in when enough water is present, ...

Chemists reveal novel biocatalysts for bioactive alkaloid synthesis

23-Feb-2017

Alkaloids are natural nitrogen-containing compounds produced by plants and microbes. These molecules, such as morphine and quinine, are important human medicines. Alkaloids are typically polycyclic in nature. While the polycyclic characteristics are important for their bioactivities, these ...
