• Sulfur Chemistry of Exploding Stars

  Sulfur Chemistry of Exploding Stars Meteorite contains evidence of formation of sulfur molecules in the ejecta of a supernova explosion. Image: Star dust from a supernova - the electron microscopic image shows a silicon carbide grain from the meteorite Murchison. The approximately one micrometer small grains originate from a supernova as an isotopic analysis has shown. Isotopes are forms of an element with different weights.

• The Great Gas Hydrate Escape

  The Great Gas Hydrate Escape Computer simulations revealing how methane and hydrogen pack into gas hydrates could enlighten alternative fuel production and carbon dioxide storage industries. Image: A computer simulation of methane, also known as natural gas, escaping from a methane hydrate. Many of these methane hydrate subunits combine to form a chunk of ice that burns, and this simulation shows how methane can get out without collapsing the entire structure ...

• Amphotericin B - New Studies on the Mechanism of Action

  Amphotericin B - New Studies on the Mechanism of Action Powerful drug's surprising, simple method could lead to better treatments. Image: This is a model of amphotericin, the most relied-upon drug for treating fungal infections, despite its toxicity. [Credit: Martin Burke]

• Continuous-Flow Synthesis of Artemisinin

  Continuous-Flow Synthesis of Artemisinin Anti-malaria drug synthesised with the help of oxygen and light. Image: A continuous-flow process that converts dihydroartemisinic acid into artemisinin is shown to be an inexpensive and scalable process that can ensure a steady, affordable supply of artemisinin.

• Electrodissolution of Platinum

  Electrodissolution of Platinum Recycling platinum by electrochemical dissolution in an ionic liquid. Image: A noncorrosive, basic ionic liquid has been developed as a solvent system for the electrodissolution of platinum. The metal is dissolved at an ultrahigh rate, and the facile recovery of pure platinum and platinum alloys from the same solution is achieved without any additional treatment of the solution or exchange of the medium.
