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 ...

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 ...

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 ...

Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

open access: yesBMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

The Heat Is On: Climate Change–Related Challenges and SMEs' R&D Activities

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Investing in R&D is a key way for small‐ and medium‐sized enterprises (SMEs) to develop capabilities that are required to respond to climate change–related challenges. However, the extent to which such challenges affect SMEs' R&D activities remains a critical gap in the literature.
