Beyond the margins of silence: Pride Groups as opportunities for student voice

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Student voice and participation are widely promoted within educational research and policy; however, the voices of LGBT+ students, and the systems through which they might meaningfully participate, remain under‐theorised. Drawing on scholarship that conceptualises voice as multimodal and symbolic, and on literature that understands silence as ...

Orchestration Up Close: Sustainable Business Model Innovation Through the Experiences and Activity Patterns of Secondary Stakeholders

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT While much research stresses the importance of stakeholder involvement and inter‐organizational collaboration in sustainable business model innovation, less is known about the dynamics and actor roles of these collaborative processes. This article investigates one particular role in the process: the orchestrator, a role taken by secondary ...

Vibrational Circular Dichroism Spectra of 2,5‐Diaminoterephtalate Macrocycles Reveal Distant Vibrational Exciton Coupling

open access: yesChemistry – A European Journal, EarlyView.
The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

open access: yesChemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...

Self‐Assembly of a Chiral Pyrene–Bifuran–Imide Into Helical and Spherical Nanostructures

open access: yesChemistry – A European Journal, EarlyView.
A chiral bifuran–imide derivative (1‐Py2) functionalized with pyrene units and an L‐alanine side chain exhibits solvent‐switchable self‐assembly. Increasing water fraction drives a transition from chiral helical fibers with periodic tail‐to‐tail bilayer packing to achiral nanospheres with orange photoluminescence.

Guanine Metal Complexes: Spectroscopic Studies, Dying Performance and as Indicator

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
Azo dyes are the most common and widely used dyes, accounting for more than half of each year's dyes. In this work, a complete description of a new innovative series of compounds with the elements [Ag (I), Zn (II)] generated from the guanine azo dye ...

Chiral Cycloparaarylenes Incorporating Binaphthyl Units: Dramatic Effects of Peripheral Functionalization on (Chir)Optical Properties

open access: yesChemistry – A European Journal, EarlyView.
Chiral cycloparaarylenes (CPAs) incorporating binaphthyl units were synthesized. The methoxy‐substituted and methylenedioxy‐bridged systems adopt D3‐ and C3/C1‐symmetric structures, respectively. They exhibited distinct solid‐state emission and aggregation‐induced emission enhancement (AIEE).
