Intrinsic Coordination Architecture Governing Selectivity Divergence Between Extended and Single‐Site Electrocatalysts

open access: yesAdvanced Materials, EarlyView.
Catalyst coordination acts as a loaded dice biasing reaction selectivity. Single‐atom site catalysts lock intermediates in exposed configurations, enabling continued hydrogenation and favoring oxygen‐retaining products. In contrast, extended metal surfaces fully coordinate and shield reactive centers, promoting deoxygenation pathways. This work reveals

The role of emotionality in the acquisition of new concrete and abstract words

open access: yesFrontiers in Psychology, 2015
A processing advantage for emotional words relative to neutral words has been widely demonstrated in the monolingual domain (e.g., Kuperman, Estes, Brysbaert, & Warriner, 2014).

Aesthetic preference for art emerges from a weighted integration over hierarchically structured visual features in the brain [PDF]

open access: yes, 2020
It is an open question whether preferences for visual art can be lawfully predicted from the basic constituent elements of a visual image. Moreover, little is known about how such preferences are actually constructed in the brain.

Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

The Neural Correlates of Abstract and Concrete Words: Evidence from Brain-Damaged Patients

open access: yesBrain Sciences, 2013
Neuropsychological and activation studies on the neural correlates of abstract and concrete words have produced contrasting results. The present study explores the anatomical substrates of abstract/concrete words in 22 brain-damaged patients with a ...

Gauge-independent Higgs mechanism and the implications for quark confinement

open access: yes, 2016
We propose a gauge-invariant description for the Higgs mechanism by which a gauge boson acquires the mass. We do not need to assume spontaneous breakdown of gauge symmetry signaled by a non-vanishing vacuum expectation value of the scalar field. In fact,

Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

open access: yesAdvanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Cracks in Concrete

open access: yes
Finding and properly segmenting cracks in images of concrete is a challenging task. Cracks are thin and rough and being air filled do yield a very weak contrast in 3D images obtained by computed tomography. Enhancing and segmenting dark lower-dimensional structures is already demanding.
