The world's strongest neutron beam may reveal 'perfect beer foaming'

Detergents and foam on the surface of beer have different properties depending on their composition and size, and have been studied by many scientists since ancient times. British scientists have proposed a method to analyze such bubbles using the world's strongest neutron beam. It is expected that 'the scientifically perfect beer foaming may be revealed.'

Dr. Richard Campbell, Principal Investigator at the University of Manchester , is studying foam using a mixture of polyelectrolytes and surfactants . This 'liquid obtained by mixing a polyelectrolyte and a surfactant' is a liquid similar to a commercially available shampoo and has the characteristic of being very easy to foam.

Dr. Campbell proposed a method to analyze bubbles by ' neutron spin echo method '. Regarding the neutron spin echo method, Dr. Campbell said, `` Emitting neutrons and reflecting it on liquid so that we can see the object by recognizing the light reflected on the object, and analyzing the result with a computer Will reveal a variety of information about the surface of the bubble. The information revealed by reflecting neutrons is at the molecular level and cannot be seen with the naked eye. '

Dr. Campbell asked the Laue Langevin Institute in France to cooperate in irradiating the foam with a neutron beam. The Laue Langevin Institute has the strongest ultra-cold neutron source in the world and has been applied in research around the world.

'For decades, scientists have been trying to figure out how to reliably control the' life and stability of foams made from liquids containing mixed additives ', says Dr. Campbell. In previous research, the point of `` what kind of liquid is what makes long-lasting foam '' was studied, but the part `` how molecules move on the surface of long-lasting foam '' is He was hardly noticed.

`` Using a neutron beam to observe the molecular motion of the bubble surface will help us understand what bubbles are stable and how to make the bubbles last longer, '' Dr. Campbell claims. You.

The research method devised by Dr. Campbell can analyze all foams in liquids, so it can be applied to research and development of shampoos used daily, creams added to coffee, fire extinguishing agents, and oil absorbing materials used to cope with environmental disasters. Manchester University commented, '(Dr. Campbell's research) has taken a big step in figuring out the perfect way to make beer foam. Drinkers will soon go to the bar to cheer and thank the research team.' did.
