1:56 PM | So you want to develop sustainable polymers, do you?
Here's a short description of the polymer production industry and what the challenges of bringing a new polymer into the world.6 plastics dominate: high- and low-density polyethylene, polypropylene, polystyrene, polyethylene terephthalate and polyvinyl chloride. They make up 76% of the market. These polymers are produced in factories that cost endless billions of dollars of capital and more are constantly being built around the world.Nobody is going to idle all that capacity without a fight.

7:40 AM | Crumpled graphene boosts performance of high-energy lithium storage materials
A three-dimensional crumpled graphene-encapsulated nickel sulfide electrode is reported as a superior high-energy lithium storage material. Compared with an electrode without crumpled graphene encapsulation, the optimized electrode yields significant improvements, especially in the cycling stability and rate capability. This enhanced performance is attributed to the 3D framework providing high continuous electron pathway and more free space for charge and mass transfer, and the stabilizing […]

11:52 PM | Synthetic Cannabinoid Illnesses in Indiana - August 2014
There are reports out of Fort Wayne, Indiana regarding six people hospitalized in a 12 hour period after using a synthetic cannabinoid product. While the overall number of people presenting is small, it was enough to garner some attention. No product names are given and no synthetic cannabinoids are named. Indiana has some strong laws around these compounds, including an exhaustive list of explicitly banned compounds and structural classes. The state also employs an analog clause and an […]

5:38 PM | BREAKING NEWS: New York resident moves somewhere else for their first job
This New York Times article touting folks moving to middle of the country caught my eye today (emphasis mine):Affordable Housing Draws Middle Class to Inland Cities ...Rising rents and the difficulty of securing a mortgage on the coasts have proved a boon to inland cities that offer the middle class a firmer footing and an easier life. In the eternal competition among urban centers, the shift has produced some new winners. Oklahoma City, for example, has outpaced most other […]

1:45 PM | What is Tetrahydrofuran?
Tetrahydrofuran is a synthetic heterocyclic compound – more specifically a cyclic ether – not found in the natural environment. It forms a colourless solution with an acetone-like odour, commonly used as a solvent and as a precursor in multiple industrial processes in the manufacture of polymers. This compound is highly flammable and may form carbon [...]

7:11 AM | Nitrogen tunes carbon-sulfur interfaces for stable lithium-sulfur batteries
Sulfur is a very intriguing solution for the design of high energy density storage devices. The lithium-sulfur battery theoretically delivers an energy density which is 3-5 times higher than traditional lithium-ion batteries. Unfortunately, several obstacles so far have prevented the practical demonstration of sulfur-based cathodes for Li-S batteries. Among them, the most important one is the rapid capacity fading. Researchers have now developed a novel strategy towards highly stable Li-S […]
