Where do the drugs go?

Drug delivery inside the body is a complicated process. Compounds travel through a maze of aqueous solutions, lipid membranes, and barriers between the blood and tissues like the brain. Research reported in the American Institute of Physics publication the Journal of Chemical Physics presents a theoretical model that accurately predicts the hydration free energy (HFE) of a wide variety of ...

Solar-powered process could decrease carbon dioxide to pre-industrial levels in 10 years

(PhysOrg.com) -- By using the sun's visible light and heat to power an electrolysis cell that captures and converts carbon dioxide from the air, a new technique could impressively clean the atmosphere and produce fuel feedstock at the same time. The key advantage of the new solar carbon capture process is that it simultaneously uses the solar visible and solar thermal components, whereas the ...
