Atomic Mass Periodic Table After many years of research, the periodic table was finally developed by Dmitri Mendeleev who proposed that the elements be organized by atomic mass. Characteristics, such as metal, metalloid, or. So how did nature fill up the periodic table? The story starts at the beginning. The very beginning. Within 15 minutes of the Big Bang,

Fig 2. Schematic representation of PET principle. (A) After travelling in tissue (positron range) positron looses energy and annihilates with electron resulting in two 511 keV annihilation photons travelling in opposite directions; (B) Annihilation photons are registered externally by radiodetectors consisting of scintillation crystals and photomultiplier tubes and assembled in a ring.

However, the copper-free click chemistry approach from Hoogenboom et al (2016) offers a novel method to fluorescently label plant glycans with high specificity and low toxicity.

In the last few years, several interesting reviews have been published, which give a comprehensive overview on the chemistry of POx and design strategies for functionalized POx [, , ] as well as their physico-chemical properties [].Hence, this wide field, which also has seen very interesting developments in recent years will not be covered in detail here.
