Twisting Lamellae Triggering Circular Polarized Luminescence of Chromophoric Moieties in Banded Spherulites With Evolution of Homochirality

Advanced Optical Materials, EarlyView.
Crystallization‐mediated hierarchical chirality is shown to transform molecular stereochemistry into macroscopic circularly polarized luminescence. Twisted PLA crystalline lamellae generate asymmetric surface stress and chiral steric environments that direct achiral chromophore organization, producing opposite CPL responses in PLLA and PDLA matrices ...

A Better Deal for Cohabiting Fathers? Union Status Differences in Father Involvement [PDF]

We use the package deal framework to study the trajectory of father involvement over time as a function of union status, while also examining reporting differences in father involvement by parent gender.

TiO2 as Trap Sensitizer for Enhanced Persistent Luminescence in ZnGa2O4:Cr3+ Nanoparticles

Advanced Optical Materials, EarlyView.
Interfacial engineering enables non‐optical charging enhancement in persistent phosphors. By coupling ZGO:Cr nanoparticles with TiO2 through a porous SiO2 interlayer, photogenerated carriers are efficiently transferred and stored in additional trapping states.

Unmarried African American Fathers’ Involvement with Their Infants: The Role of Couple Relationships [PDF]

Almost one-third of all children and 70% of African American children in the U.S. are born to parents who are not married. At the time of children’s births, almost all unmarried fathers have contact with their infants, but this connection drops over time.

First-time fathers' experiences during childbirth education, labour and delivery, and during their first year as fathers [PDF]

, 2011
In many western societies, fathers have traditionally assumed the role of breadwinner in the family, leaving responsibilities for parenting to the mother. It was not until the late 20th century that their role as participating and caring fathers evolved,
