Supercapacitor Safety: Overcharge‐Induced Failure Mechanisms in Electrochemical Double‐Layer Capacitors

open access: yesAdvanced Science, EarlyView.
Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

open access: yesChemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

14C wiggle-matching of short tree-ring sequences from post-medieval buildings in England [PDF]

open access: yes, 2019
This study tests whether accurate dating by AMS radiocarbon wiggle-matching short tree-ring series (c. 30 annual rings) in the period after AD 1510 can be achieved routinely.

Wiggle-Match Dating of Wooden Samples from Iron Age Sites in Northern Italy [PDF]

open access: yesRadiocarbon, 2010
Archaeological excavations carried out at the sites of Laion/Lajen (Bolzano/Bozen) and Stufles-Oberegger (Bressanone/Brixen) in northern Italy uncovered well-preserved wooden samples in cultural layers archaeologically dated to the Iron Age. From the 2 sites, different wooden samples were recovered that were well preserved enough to allow clear ...

Tree-Ring Chronological Investigation on the Oak Poles of the Prehistoric Settlement of “Gran Carro” in Lake Bolsena, Central Italy: Landscape and Human Occupation

open access: yesLand
Dendrochronological analysis was carried out at the archaeological settlement of Gran Carro, located in Lake Bolsena (Italy). According to the most recent archaeological evidence, the site dates back to the period spanning from the Middle Bronze Age ...

Using Displacement‐Assisted Desorption to Identify Reactive Intermediates: Ring‐Fused Porphyrins on Cu(111)

open access: yesChemistry – A European Journal, EarlyView.
We propose a novel displacement‐assisted approach for temperature‐programmed desorption (TPD), allowing for the detection of reactive intermediates of on‐surface reactions. We demonstrate the approach by investigating the temperature‐dependent ring fusion reactions (cyclodehydrogenations) of tetraphenylporphyrin on Cu(111), revealing the quantitative ...

Investigating the toll of childhood socioeconomic disadvantage on adolescent mental health in three UK cohorts

open access: yesJCPP Advances, EarlyView.
Abstract Background Low socioeconomic position (SEP) in childhood is robustly associated with adolescent mental health difficulties, yet this relationship is changing over time due to contextual and conceptual differences in these constructs. Consistent SEP and mental health data from different cohorts are required to understand changes over time ...

Differences in associations between attention‐deficit hyperactivity disorder symptoms and physical activity across childhood and adolescence and among males and females in a representative UK birth cohort

open access: yesJCPP Advances, EarlyView.
Abstract Background Children and adolescents with attention‐deficit hyperactivity disorder (ADHD) exhibit higher physical activity (PA) levels than peers without ADHD. It remains unclear how this association evolves across developmental stages and differs between sexes.

Intergenerational Altruism and Sustainable Development: The Role of Descendants and Age Effects in Promoting Future Well‐Being

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainability challenges can be framed as problems of intergenerational altruism—how the current generation allocates resources to future generations. Institutional reforms such as Demeny voting assume that descendants act as intermediaries who enhance altruism toward the future. We test this “altruism premium” and evaluate two interventions,

Self‐Assembly of Hierarchically Structured Materials From Liquid Crystalline Mesophases of Tobacco Mosaic Virus‐Like Particles

open access: yesSmall, EarlyView.
Recombinantly produced Tobacco Mosaic Virus coat protein (TMVcp) helical rods were demonstrated to reproducibly self‐assemble into hierarchically structured macroscopic filaments, driven by a lyotropic liquid crystal (LC) intermediate phase. The results indicate anisotropic molecular alignment of the fluid phase, retention of the native secondary ...
