Synthesis and self-assembly of multiblock and Janus particles
We develop general guidelines for the rational design of both building blocks and interaction patterns of patchy colloids in liquid suspension, towards the long-term goal of developing the practical capability to make a colloidal structure, or any colloidal material, that is “assemblable”. Two …

Soft Compartmentalized Polymer Colloids: Janus Particles, Multicompartment Structures, Inorganic-Organic Hybrids and Applications
… solvents. Cylindrical and disc-like Janus particles were investigated according to their self-assembly behavior into superstructures. The Janus discs undergo back-to-back stacking in organic solvent. In aqueous solution, a size-dependent aggregation was found. While the smaller Janus …

The Janus-face of capitalist labor: gender, race, and work in early modernity
<p>The dissertation thus attempts to chart the interrelationship between three processes during the early modern period: the enwaging of the nascent proletariat, the domesticating of white women, and the enslavement of peoples of color. These three tendencies, taken together, represent the …

Designing Particle Tracking Software for a Theoretical Understanding of Magnetic Janus Particle Aggregation
<p>Magnetic Janus particles are spherical colloids covered with a thin magnetic cap on one half of their surface. The asymmetric magnetic material gives the particles a magnetic dipole shifted away from the center of mass of the particle. The magnetic dipole either points perpendicular …

Studying Janus behavior : how support, deterrence, grievances and organizational structure shape violent and peaceful behaviors
… of a gentler sort. These groups exhibit "Janus-faced" personalities, simultaneously including militancy and nonviolent mobilization in their toolbox of behavioral options. In order to be seen as legitimate actors in the political arena, these groups eventually must forswear violence. …
