Stress Transfer Within Microphase‐Separated Structures: A Post‐Synthetic Strategy to Impart Mechanoresponsiveness to Block Copolymer Materials

Advanced Materials, EarlyView.
A domain‐engineered post‐functionalization strategy is presented to impart mechanochromism to styrene–butadiene–styrene (SBS) block copolymers by simple blending with a tetraarylsuccinonitrile (TASN) mechanophore‐containing polystyrene (PS‐TASN‐PS). The resulting materials exhibit reversible fluorescence under tensile deformation while preserving, or ...

Efficient Hydroxyl Diffusion Triggers Surface Hydronium Enrichment and Bulk Proton Participation to Boost Alkaline Hydrogen‐Evolving Reaction

Advanced Materials, EarlyView.
For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...

The g-Strained EPR Line Shape of Transition-Ion Complexes and Metalloproteins: Four Decades of Misunderstanding and Its Consequences

Molecules
Analysis of the EPR of dilute transition-ion complexes and metalloproteins in random phases, such as frozen solutions, powders, glasses, and gels, requires a model for the spectral ‘powder’ shape.

An evolutionary approach to modelling concrete degradation due to sulphuric acid attack [PDF]

, 2014
Concrete corrosion due to sulphuric acid attack is known to be one of the main contributory factors for degradation of concrete sewer pipes. This paper proposes to use a novel data mining technique, namely, evolutionary polynomial regression (EPR), to ...

Quantitative comparison of different iron forms in the temporal cortex of Alzheimer patients and control subjects

Scientific Reports, 2018
We present a quantitative study of different molecular iron forms found in the temporal cortex of Alzheimer (AD) patients. Applying the methodology we developed in our previous work, we quantify the concentrations of non-heme Fe(III) by Electron ...

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

Advanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.
