Studies relying on institutional theory have revealed the possibilities of resistance to dominant institutional forces (Lepoutre & Valente,2012; Marquis & Lounsbury,2007; Pache & Santos,2010; Schneiberg,2013). However, while these studies emphasize how alternative practices can be strategically leveraged ...
Acrylic monomers are known to undergo autoinitiation at high temperatures (>200 °C) via a Flory-type autoinitiation mechanism, whereby two monomers react via an open-shell singlet pathway to form diradical species (Fig. 5a)37,39,40,41. However, autoinitiation at lower temperatures has ...
The familial form of amyotrophic lateral sclerosis, or FALS, has been shown to be associated with defects in the gene encoding Cu,Zn-SOD (sod 1) (46, 47, 48). That this disease was due to a toxic gain of function of the mutated protein, rather than to a loss of SOD activity, was...
Linking into Mouffe's own work, as opposed to a destructive, unproductive contest, this hegemonic contest can be perceived as taking the form of agonism where those engaging in such politics do so as adversaries (see Mouffe 2005a, p. 20). While all may be committed to the concept of ...
(TBADT,Scheme 58).244Generation of the radical occurred via direct H-atom abstraction by the excited form of the catalyst, using 3 equivalents of oxetane. The oxetane radical was then trapped with various electron-poorolefinsas the limiting reagents. 2-Substituted oxetanes gave a mixture of 2,...
The temperature-sensitive solubility of PDMAEMA in water also renders it potentially applicable in fields such as drug delivery systems, sensors, etc.1,2 Amphiphilic block copolymers of DMAEMA form micelles and act as stabilizers in dispersion polymerizations.3-5 Recently, DMAEMA has been polymerized...
The first of these offers a novel theoretical approach to the radical pair mechanism in the form of the collective coupling model. The second looks more closely at the hyperfine environment of the radical pair to see how altering hyperfine coupling strength might alter radical pair dynamics. The ...

intermolecular addition of fluoroalkyl radicals to unactivated alkenes has emerged as one of the most attractive strategies for the direct 1,2-difunctionalization of alkenes to simultaneously construct two vicinal chemical bonds by using a variety of radical fluoroalkyl precursors in racemic form21–27....
