We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

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...

Hops contribute many desirable aromas to beer. Traditionally hop aromas have
been described by the point of addition in the brewing process (dry-hop, finish-hop, or
kettle-hop). The compounds present in the oil provide a wide range of aroma qualities.
Since the composition of the oil is different for each hop...
This study seeks to show how a member of an empowered group is able to argue
on behalf of a disempowered group. Other theorists in the field of other-directed
protest have claimed that these protestors have a negative effect on the
disempowered group and only serve to raise their own...
Vitamin E was first described in 1922 as an unknown factor required for impregnated rats to carry their offspring to term. In fact, when vitamin E was chemically characterized it was given the name "tocopherol" derived from the Greek: tokos = childbirth; phero = to bear; and –ol, indicating an...
