Selected papers from the latest issue:Adaptation to High Current Using Low External Resistances Eliminates Power Overshoot in Microbial Fuel Cells

One form of power overshoot commonly observed with mixed culture microbial fuel cells (MFCs) is doubling back of the power density curve at higher current densities, but the reasons for this type of overshoot have not been well explored. To investigate this, MFCs were acclimated to different external resistances, producing a range of anode potentials and current densities. Power overshoot was observed for reactors acclimated to higher (500 and 5000Ω) but not lower (5 and 50Ω) resistances. Acclimation of the high external resistance reactors for a few cycles to low external resistance (5Ω), and therefore higher current densities, eliminated power...

We investigated the use of functionalized photonic block copolymer films for the detection of glucose. Polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymers were chemically functionalized with 2-(bromomethyl)phenylboronic acid and cast into films that reflect a visible color when exposed to aqueous media. The 2-(bromomethyl)phenylboronicacidfunctionality can reversibly bind to glucose. When exposed to high concentrations of glucose the polymer responded with a redshift in color. Low concentration exposure of glucose caused the polymer films to blueshift in color. The BCP films also exhibited a selective response to fructose, mannose or galactose, giving a different response depending on which sugar is present. The color...
