Chemical reactions iPhone app
Learning named reactions has never been easier thanks to ReactionFlash. Named organic chemistry reactions - usually named after their discoverers - are a fundamental part of every chemist's toolkit. ReactionFlash helps you learn and understand named reactions: from the famous, to those you've forgotten, to those only a Nobel Prize Winner knows! Not only does the app give you the reaction, it also shows you the known mechanism, recent literature examples from Reaxys ®, and even allows you to test your skills with the ReactionFlash quiz.

Powering up organic solar
Organic offers many advantages over conventional semiconductors for solar-energy conversion technology. Among those advantages are low-cost, low-density and scalable surface area. However, organic also comes with a disadvantage: low efficiency. Many teams around the world are hoping to break this latter obstacle, and now US chemists have found that Stille coupling of two highly conjugated monomers can produce an organic polymer with a small band gap and high power conversion efficiency. Solar cells built from these polymers were approximately 6% efficient, which is relatively high for organic materials and inching towards the 10% tipping point.
