Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via

Using Comprehensive Two-Dimensional Gas Chromatography to Study the Atmosphere [PDF]

Journal of Chromatographic Science, 2010
The atmosphere is a highly complex, highly reactive chemical system. There are a huge variety of emission sources of chemical compounds, both natural and man-made, which have a broad range of reactivities and can be oxidized in the atmosphere to form an even more complicated matrix of oxidation products with a multitude of atmospheric lifetimes.
