The natural molecules which are used, rather within the components of pharmacy and agrochemicals, have gotten progressively more complicated either of their chemical nature and spacial configuration. a posh molecular constitution is necessarily fragile; it can't be produced lower than serious stipulations (in specific excessive strain and temperature). furthermore there's a challenge of the scale-up of a product from the laboratory to the economic scale. The keep watch over of the reactivity, selectivity, and yield and using sufficiently gentle business stipulations are all components that has to be taken into consideration by way of business chemists. among the ''tools'' giving controllable reactivity, selectivity, and comparatively light response stipulations is bromine. The natural chemistry of bromine occasionally provides incredible selectivities in comparison to these of chlorine. This quantity that's in accordance with ''Orgabrom '93'', brings jointly the most contributions offered at this occasion.

During this Festschrift devoted to the sixty fifth birthday of Marco Antonio Chaer Nascimento, chosen researchers in theoretical chemistry current study highlights on significant advancements within the box. initially released within the magazine Theoretical Chemistry bills, those amazing contributions at the moment are to be had in a hardcover print layout.
This PhD thesis offers the most recent findings at the tunable floor chemistry of graphene/graphene oxide by way of systematically investigating the tuning of oxygen and nitrogen containing practical teams utilizing an cutting edge carbonization and ammonia remedy. additionally, novel macroscopic assemblies or hybrids of graphene have been produced, laying the theoretical origin for constructing graphene-based power garage units.
