Origin of Dark Current Robustness in Photomultiplication Organic Photodetectors Enabled by Ionic Conjugated Electron‐Blocking Layers

open access: yesAdvanced Materials, EarlyView.
Ionic conjugated polyelectrolyte electron‐blocking layers enable photomultiplication organic photodetectors with dark current robustness up to −10 V and external quantum efficiencies exceeding 3000%. Fowler–Nordheim tunneling, interfacial dipole, trap density of states, and noise analyses reveal how ionic conjugated polyelectrolytes suppress electron ...

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

open access: yesAdvanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

Chlorine‐Functionalized Silane‐Modified Copper Electrocatalyst for Enhanced CO2 Reduction to Multi‐Carbon Products

open access: yesAdvanced Science, EarlyView.
A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

open access: yesAdvanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

Mitigating HLA Disparity in AML Transplantation: Comparable Outcomes After Haploidentical and 9/10 Mismatched Unrelated Donor Transplantation With Treosulfan and PTCy

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic stem cell transplantation (allo‐HSCT) is a potentially curative strategy for acute myeloid leukemia (AML), but the impact of HLA disparity in the era of posttransplant cyclophosphamide (PTCy) and reduced‐toxicity conditioning remains unclear. We performed an EBMT registry study including 275 adult AML patients in first

IRM et myocardite infectieuse

open access: yesAnnales de Cardiologie et d'Angéiologie, 2020
Over the past ten years, cardiac MRI has become an indispensable tool for acute myocarditis diagnosis. Under appropriate conditions, cardiac MRI may allow postponement of initial coronary angiography in many instances. The 2020 ESC guidelines give a class I recommendation to its use in the setting of MINOCA for differential diagnosis between acute ...

Essential work, invisible workers: The role of digital curation in COVID‐19 Open Science

open access: yesJournal of the Association for Information Science and Technology, Volume 76, Issue 4, Page 703-717, April 2025.
Abstract In this paper, we examine the role digital curation practices and practitioners played in facilitating open science (OS) initiatives amid the COVID‐19 pandemic. In Summer 2023, we conducted a content analysis of available information regarding 50 OS initiatives that emerged—or substantially shifted their focus—between 2020 and 2022 to address ...

Récidive d´un Sarcome d´Ewing primitif à localisation temporale: à propos d´un cas et revue de la littérature

open access: yesPAMJ Clinical Medicine, 2020
L´atteinte primitive de la voûte du crâne au cours du sarcome d´Ewing est très rare et représente moins de 1 % de toutes les localisations. L´atteinte de l´os frontal et pariétal semble être la plus fréquente mais les localisations au niveau occipital et
