Mass spectrometry , which is what determines the volatile content and, consequently, the one that can provide information on the aroma of whiskey, has proven to be the most efficient technique to identify it , above ultraviolet-visible spectroscopy for color and infrared spectroscopy for taste. This is what a study carried out by researchers from … Read more
It was not until 1789 that the French chemist Antoine Lavoisier succeeded in showing the role of oxygen in combustion, and consequently exposed the phlogiston theory of Georg-Erns Stahl , which had dominated scientific thought for half a century (and that until not long ago, it also dominated much of the literature). Phlogiston was an … Read more
It is still quite unknown how the impurities contained in the color mixtures that are injected into the skin, the tattoos, react when they leak into the body of the tattooed person.

Turing’s idea … Read more
Although intuitively we discover great differences between solid, liquid or gaseous objects, they are fundamentally the same thing: it only differs in the behavior of the molecules that make them up . It was all gas For that reason, with enough heat, all the elements of the periodic table can theoretically turn into gas, no … Read more
The periodic table is an important scientific tool but difficult to memorize, in addition to that, for lay people, it offers little information about what we are reading. Keith Enevoldsen , a software engineer with a degree in physics, has created a more useful version of the periodic table that makes it easy to see … Read more
A new analysis shows that half of the canvas being held in Amsterdam is painted with pigments that darken on exposure to ultraviolet light. Vincent Van Gogh could hardly have predicted that, more than a century later, those bright yellow hues would begin to fade into brown confusion. X-rays A new X-ray study confirms what … Read more
