Distinguishing Different Stackings in Layered Materials via Luminescence Spectroscopy.

Despite its simple crystal structure, layered boron nitride features a surprisingly complex variety of phonon-assisted luminescence peaks. We present a combined experimental and theoretical study on ultraviolet-light emission in hexagonal and rhombohedral bulk boron nitride crystals. Emission spectra of high-quality samples are measured via cathodoluminescence spectroscopy, displaying characteristic differences between the two polytypes.

Family Resilience and Dyadic Coping during the Outbreak of the COVID-19 Pandemic in Italy: Their Protective Role in Hedonic and Eudaimonic Well-Being.

The COVID-19 pandemic outbreak has dramatically worsened people's psychological well-being. Our aim was to examine for the first time the concurrent and longitudinal relations of family resilience with hedonic and eudaimonic well-being, and the moderating role of socio-demographics. For people having a romantic partner, we also explored whether family resilience and dyadic coping were uniquely related to well-being.

Intrinsic Control of Interlayer Exciton Generation in Van der Waals Materials via Janus Layers.

We demonstrate the possibility of engineering the optical properties of transition metal dichalcogenide heterobilayers when one of the constitutive layers has a Janus structure. We investigate different MoS@Janus layer combinations using first-principles methods including excitons and exciton-phonon coupling. The direction of the intrinsic electric field from the Janus layer modifies the electronic band alignments and, consequently, the energy separation between dark interlayer exciton states and bright in-plane excitons.

How culturally unique are pandemic effects? Evaluating cultural similarities and differences in effects of age, biological sex, and political beliefs on COVID impacts.

Despite being bio-epidemiological phenomena, the causes and effects of pandemics are culturally influenced in ways that go beyond national boundaries. However, they are often studied in isolated pockets, and this fact makes it difficult to parse the unique influence of specific cultural psychologies. To help fill in this gap, the present study applies existing cultural theories linear mixed modeling to test the influence of unique cultural factors in a multi-national sample (that moves beyond Western nations) on the effects of age, biological sex, and political beliefs on pandemic outcomes that include adverse financial impacts, adverse resource impacts, adverse psychological impacts, and the health impacts of COVID.

Gender Differences in the Associations Between Perceived Parenting Styles and Young Adults' Cyber Dating Abuse.

Existing literature indicates that parenting styles affect the development of cyber aggression in offspring differently, depending on the gender of children. The present study investigates whether mothers' and fathers' parenting styles show similar gender differences in their associations with a new form of dating violence, i.e.
