Evaluation of novel hybrid membranes for carbon capture

EurekAlert! - Jue, 11/16/2017 - 23:00
Hybrid materials known as mixed matrix membranes are considered a promising approach to capture carbon dioxide and mitigate against global warming. These materials are derived from a polymer combined with porous nanoparticles. We show that materials prepared using porous organic polymers are resilient to the acidic impurities present in industrial gas streams, whereas other hybrid materials fail. This means that they can be effective in carbon capture applications where these impurities are present.

Researchers tunnel to a new light source

EurekAlert! - Jue, 11/16/2017 - 23:00
The Ohio State University researchers, with scientists at Wright State University and Naval Research Laboratory, describe a promising new semiconductor LED made with GaN-based materials that could boost wallsocket efficiency by reducing energy losses and self-heating. If this new technology can be harnessed for large light output, the breakthrough could enhance LED solid state lighting without a significant change to the existing LED manufacturing facility.

Vaginal progesterone reduces preterm birth and neonatal complications in women with a mid-trimester short cervix

EurekAlert! - Jue, 11/16/2017 - 23:00
Prematurity is the main complication of pregnancy, and 15 million babies are born preterm worldwide each year. Physicians worldwide have investigated whether vaginal progesterone administration to women with a mid-trimester sonographic short cervix reduces the rate of preterm birth. Now physicians and researchers have found that when all available information is considered in an individual patient data meta-analysis, the results are clear: vaginal progesterone reduces the rate of preterm birth at <28, <30, <32, <34, <35, and <36 weeks.

Surrey develops new 'supercatalyst' to recycle carbon dioxide and methane

EurekAlert! - Jue, 11/16/2017 - 23:00
The University of Surrey has developed a new and cost-effective catalyst to recycle two of the main causes behind climate change -- carbon dioxide (CO2) and methane (CH4).

Scientists capture colliding organic nanoparticles on video for first time

EurekAlert! - Jue, 11/16/2017 - 23:00
A Northwestern University research team is the first to capture on video organic nanoparticles colliding and fusing together. This unprecedented view of 'chemistry in motion' will aid Northwestern nanoscientists developing new drug delivery methods as well as demonstrate to researchers around the globe how an emerging imaging technique opens a new window on a very tiny world.

The future of cell culture: A new continuous bioprocess developed

EurekAlert! - Jue, 11/16/2017 - 23:00
Scientists at Newcastle University, UK have developed a revolutionary technique to allow the continuous production and collection of cells.
