Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

A “Principled Resolution”: The Fulcrum for Bioethics Mediation [PDF]

open access: yes, 2011
The concept of a principled resolution is the foundation for bioethics mediation. Dubler presents the core bioethical principles that support the creation of principled resolutions as fulcrums for resolving disagreements in the healthcare setting ...

Photoswitching Conduction in Framework Materials

open access: yesAdvanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

When you Think you Know: The Effectiveness of Restrictive Mediation on Parental Awareness of Cyberbullying Experiences Among Children and Adolescents

open access: yesCyberpsychology: Journal of Psychosocial Research on Cyberpspace
The current study examined parental awareness of their child’s cyberbullying experiences in relation to the implementation of restrictive mediation strategies (e.g., interaction and technical restrictions) among children in elementary school and ...

Three‐dimensional Antimony Sulfide Based Flat Optics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Helicopter apps and parental mediation: facts and myths about parental controls [PDF]

open access: yes, 2016
Bieke Zaman and Marije Nouwen take a closer look at state-of-the-art parental controls, and call for a more nuanced approach that balances online risks against online opportunities. Both Bieke and Marije are researchers at the Meaningful Interactions Lab
