The Insistence of Blackness and the Persistence of Antiblackness in Ireland

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Slowing Down Water: Enhanced and Cation‐responsive MRI Contrast

open access: yesAngewandte Chemie, EarlyView.
The controlled modification of mesoporous silica nanoparticle side walls with kosmotropic motifs supports an ability to reduce water diffusive mobility and dramatically increase MRI contrast to levels unprecedented for highly kinetically stable Gd‐DOTA configurations (both q = 1 and q = 0).

Cyclo‐Polyproline: Chameleonic All‐Peptide Macrocycles With Induced‐Fit Host‐Guest Recognition

open access: yesAngewandte Chemie, EarlyView.
Macrocycles served as the genesis of supramolecular chemistry, advancing synthetic, separation, and materials fields. Despite their utility, they typically lack synthetic control. This work establishes a robust platform for all‐peptide macrocycles capable of host‐guest complexation and chameleonic behavior.

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

open access: yesAngewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

open access: yesAngewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...
