A significant challenge for energy storage technologies is to realize battery-level energy density and capacitor-level durability and
power density in one device. By introducing an electrolyte composed of an anionic catholyte and a cationic anolyte into a symmetric
carbon-based supercapacitor configuration, a hybrid electrochemical battery-supercapacitor system using soluble redox species...

Artificial lipid bilayer technologies are effective models for studying cell membrane properties. Droplet bilayers rely on microfluidics and provide advantages over other bilayer methods due to their compatibility with automated development systems that increase yield while minimizing cost. This paper describes the implementation of bilayer technologies using membrane protein channels...
Electrochemical double-layer capacitors exhibit high power and long cycle life but have low specific energy compared with batteries, limiting applications. Redox-enhanced capacitors increase specific energy by using redox-active electrolytes that are oxidized at the positive electrode and reduced at the negative electrode during charging. Here we report characteristics of several...

Turbulent flow with suspended, non-spherical particles can be found in nature and several industrial applications. Although turbulence with dispersed spherical particles has been studied extensively, modeling the dynamics of non-spherical particles in a turbulent flow has not been studied extensively. Motion of spherical particles in complex flows is typically captured...
The dilute sulfuric acid hydrolysis of annual rye grass (Lolium
multiflorum) straw was investigated. The straw was hydrolyzed in a
stainless steel pressure bomb at 121° C, 135° C, and 150° C with
0.5 to 3.0 percent sulfuric acid for time periods up to 40 minutes.
These conditions resulted in...
Most studies of plant disease epidemiology have focused on epidemics in host
populations composed of a single genotype. But crop plant diversity can be a useful
means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...
Many natural resources such as water and forests have become more intensively used in recent years. Often, this has made it necessary to reallocate these resources from less to more efficient productive usage. The knowledge of the existing tradeoffs between alternative uses are necessary to make reallocative decisions. However, these...
