Sequestering CO2 for Short-Term Storage in MOFs: Copolymer Synthesis with Oxiranes

In this study, we have demonstrated that CO2 collected under aerobic conditions at atmospheric pressure over [Cu3(btc)2(H2O)3] (btc = benzene-1,3,5-tricarboxylate) or HKUST-1, a commercially available metal-organic framework material (MOF), can be utilized to synthesize poly(propylene carbonate) from propylene oxide and CO2 catalyzed by Co(III) salen catalysts at optimal pressure. That is, CO2 thermally released from the MOF material selectively affords copolymer in the pressure range that is not rate-limiting.

Comparisons of Ultrafine and Fine Particles in Their Associations with Biomarkers Reflecting Physiological Pathways

Using a quasi-experimental opportunity offered by greatly restricted air pollution emissions during the Beijing Olympics compared to before and after the Olympics, we conducted the current study to compare ultrafine particles (UFPs) and fine particles (PM2.5) in their associations with biomarkers reflecting multiple pathophysiological pathways linking exposure and cardiorespiratory events.

Study: Fuels from corn waste not better than gas

WASHINGTON (AP) - Biofuels made from the leftovers of harvested corn plants are worse than gasoline for global warming in the short term, a study shows, challenging the Obama administration's conclusions that they are a much cleaner oil alternative and will help combat climate change.

How To Design Your Workspace To Encourage Positive Emotions At Work

Steelcase just completed a two year study of well-being in the workplace in which it found that, to foster a workforce of employees who are productive, collaborative, and creative, organizations need to consider much more than just the physical health of their employees. Rather, they need to take a holistic approach to well-being, understanding the emotional and cognitive, as well as physical needs of employees.

Know Your Workers: Are They Safety-Oriented or Risk Takers?

Through a series of studies with outside organizations, Stephen Race, head of research at TalentClick, and his team discovered a strong correlation between five personality characteristics and workplace safety incidents. The five core risk-related traits include resistance, anxiousness, irritability, distractibility and impulsiveness. Individuals who are considered higher-risk in any of these categories, Race says, can be a threat to their own safety and that of others. (press release)
