Open-Shell Analogs of Closed Shell Reaction Paths: the SRN2' case

Shell Analogs of Closed Shell Reaction Paths : The Sw 2 ’ Case

Two major pathways exist in substitution reactions of nucleophiles with allylic substrates (Scheme l).IF3 Attack of the nucleophile at the carbon atom bearing the allylic leaving group leads to direct displacement in a classic sN2 mechanism. Alternatively, attack can also occur at the terminal carbon atom of the allylic double bond, displacing the leaving group in a concerted or consecutive man...

Controllable self-assembly of amphiphilic macrocycles into closed-shell and open-shell vesicles, nanotubes, and fibers.

Depending on functional groups, amphiphilic hexaamide macrocycles self-assemble into closed-shell and open-shell vesicles in polar solvents. In the presence of water, open-shell vesicles morph into closed-shell vesicles, whereas acidification of the medium transforms vesicles into nanotubes and fibers.

Electronic structures and reaction dynamics of open-shell species.

Investigating Different Methods of Closed Shell Pistachios Splitting and Effects of Freezing Prior to Drying on Shell Splitting Percentage

In this study, different methods for shell splitting and the effect of freezing prior to drying on shell splitting percentage of pistachio were investigated. A completely randomized design was used to investigate the effects of different freezing temperatures (0, -6, -12 and -18°C), different drying temperatures (80, 90 and 100°C) and different cultivars (Akbari and Kalehghouchi) on shell split...

Open-Shell Benzenoid Polycyclic Hydrocarbons

Graphene has been found to be an attractive material since its discovery in 2004 and has drawn enormous interest among researchers owing to its intrinsic electronic and magnetic properties. An indefinitely large graphene sheet, if cut along the two edge directions, can generate two distinct, well-defined small graphene nanoribbons (GNRs), which may be classified into “zigzag” edge (1, transpoly...
