Gold is the quintessential noble metal. Its lack of chemical reactivity, particularly to acids and atmospheric corrosion, together with is rarity and malleability make it the precious metal it is since ancient times. Today, if we go for a […]

When autumn arrives to temperate climate forests, deciduous trees lose their characteristic green tonalities and start showing a wide spectrum of new colours: yellow, brown, orange, red… Chlorophyll reabsorption takes place in the leaves and carotenoids, present in a lower […]

Imagine a very simple chemical estructure: 4 carbon and 1 nitrogen forming a ring, with no double bonds, just simple bonds between any two of them and with hydrogen. This compound is called pyrrolidine and is the base of very […]

Nanopore DNA sequencing was one the ten scientific breakthroughs of 2016 highlighted by Science magazine. In principle, graphene is the perfect pore material for DNA sequencing . Its monoatomic thickness of 0.35 nm is similar to the DNA base spacing […]

Faster. That is the word that describes de evolution of electronics. Any new development has to be faster than anything before, if it is going to cope with the huge amount of information that the device where it may be […]

Carbon has four valence electrons. To fill its octet, it requires four additional electrons, which can be obtained through the formation of four covalent bonds. Carbon forms single, double, and triple bonds to achieve a filled octet. As a result, […]

Today is Monday morning and I am going to my laboratory in Niteroi by ferryboat. I took it from the XV Square of Rio de Janeiro. I am looking through the window of the ferryboat and I see one of […]

Enediynes are organic compounds containing two triple bonds and one double bond. The enediyne groups in those compounds are often called warheads. Why this name? Because, many of these compounds are capable of undergoing Bergman cyclization or, in other […]
