AIChE will undertake a routine upgrade of our digital infrastructure between 12AM to 6AM ET on Tuesday April 22. During this time access to all services that require login or payment will be unavailable.
Nanowire-based electrodes have been shown to increase the power density of batteries such as the lithium-ion battery used in consumer electronics and capacitors. Nanowires are highly conductive with a large surface-area-to-volume ratio, which...
Delivering drugs directly to cancerous tumors is not an easy task. Cancer-killing drugs are most effective when released as close as possible to the interior of the tumor to maximize the probability that they will penetrate the cancerous cells. To...
The abundance of low-cost natural gas has fueled interest in expanding the use of natural gas as a feedstock for the production of chemical intermediates, as well as in developing alternative pathways to convert methane into higher-value...
As engineers and scientists synthesize ever-smaller structures, one source of building blocks is colloidal particles. Now, a new method enables the creation of colloidal particle structures with customizable geometry and composition. The method,...
A new catalyst uses copper nanoparticles and nitrogen-rich graphene to selectively and efficiently transform CO 2 into ethylene. The researchers from Brown Univ. who developed the catalyst envision it being used to add value to the CO 2 emitted from...
Allylic oxidation is of great importance in pharmaceutical manufacturing. Existing reaction schemes, however, involve toxic reagents, such as chromium, ruthenium, or selenium, and/or expensive catalysts, such as palladium or rhodium. These factors...
Engineers at Rice Univ. have developed an electrolyte and separator for rechargeable Li-ion batteries that can safely operate in high temperatures. Batteries made with the new composite material functioned in temperatures of 150°C (302°F) for more...
Synthetic biology — an emerging field that aims to use engineering tools and principles to build biological devices and systems — holds promise for a vast range of applications, as well as for developing a better understanding of living organisms...
A new method of discovering the genetic sequences that make CRISPR work could expand the use of this gene-editing system. Most headlines about CRISPR, a bacteria-derived tool that can slice and edit a genome, are about a particular set of genes and...
