The discovery and development of new drugs is a long and expensive process, and despite of it, essential to face present and new diseases. For small molecules, which account for the majority of the marketed drugs, the discovery process generally […]

The SN2 reaction is one of the most important processes in organic chemistry and has been the subject of numerous experimental and theoretical investigations . The designation SN2 stands for substitution nucleophilic bimolecular. The reaction’s equation, […]

The effort of mapping ignorance in biology is especially frustrating –or, if the mood and attitude of the scientist afford it, especially motivating– because solid, […]

It seems to be useful to begin this short article with the following quote:
¨with courageous simplification, one might assert that the chemistry of the last century was largely the chemistry of covalent bonding, whereas that of the present century […]

Natural non-wetting structures, particularly lotus leaves (Fig. 1a), have inspired the development of synthetic liquid-repellent surfaces. These surfaces rely on the formation of a stable air–liquid interface, but present limited repellency to oils with high contact angle hysteresis, failure under […]

One of the multiple tasks of quantum chemistry is the rationalization of the bonding between atoms to form molecules. In this vein, two main aspects are clearly distinguished: i) the binding energy, or the energy gained by the molecule when […]

One of the things we learn first, when we get in touch with chemistry, is how important the acidity or alkalinity of a given solution is. This is also and quite often our firstaffair with the chemical equilibrium, […]

It is well known that an accurate and energetic laser shot can melt, ionize and excite the material in which the light is focused, creating very bright plasmas after the interaction. Valuable information can be obtained from the light emitted […]
