The Nobel Prize in Chemistry 2014

In 2014, the Nobel Prize in Chemistry was awarded to Eric Betzig and William Moerner who, working separately, laid the foundation for SMLM. In essence, this method relies on the possibility to turn the fluorescence of individual molecules on and off. Scientists image the same area multiple times, allowing only a few interspersed molecules to glow each time. By superimposing these images, a dense super-image […]

Chemistry – Energetics

If the reaction produces heat (increases the temperature of the surroundings) then it’s exothermic. If it decreases the temp (i. e. absorbs heat) then it’s endothermic. Also, the yield of an equilibrium reaction which is exothermic will be increased if it occurs at low temps, and so for endothermic reactions at high temperatures. Exothermic : A reaction which produces heat. Endothermic : A reaction which […]
