Nobel Prize

Like a successful dinner party, productive chemical reactions depend upon getting the right components to mingle in the right surroundings, and often the best environment for chemistry turns out to be a solid surface. From the cleaning of exhaust fumes in factory chimneys to the reduction of ozone on the outside of ice crystals in…

To artificially create carbon-based compounds relies on outside help to facilitate the many ways in which carbon atoms can join onto each other and other atoms. The tools of the trade are a host of chemicals, or reagents, which take part in reactions that piece together the correct molecules in the correct manner in a…

The undisputed master of chemistry is Nature, and the variety of substances it routinely creates has long been a source of inspiration and perspiration for chemists. Investigating and recreating the natural substances essential for life is a painstaking process; their size and complexity makes anything other than the simplest compounds almost impossible to reproduce under…

In biological terms the processes that aid digestion, create vitamins and manufacture plant poisons affecting the heart might seem like being worlds apart, but in terms of their chemistry they show a remarkable degree of similarity. Establishing the chemical connections that lie at the heart of these biological processes can be said to be the…

Life on earth is dependent on photosynthesis, the process in which solar light is converted into chemical energy and stored as carbohydrates. The carbohydrates are, finally, degraded to carbon dioxide and water in the cell respiration in a reaction requiring molecular oxygen. The liberated energy is utilized to power the life processes. In photosynthesis, the…
