Laboratory and synchrotron x‐ray micro–computed tomography to shed light on degradation features of corroded Roman glass

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 3, March 2025.
Abstract This study explores the three‐dimensional structure of Roman glass through the combined use of laboratory and phase‐contrast synchrotron x‐ray micro–computed tomography. This original approach validates a noninvasive analytical procedure designed to enhance the understanding of glass degradation mechanisms, crucial for the preservation of ...

Dip‐Pen Nanolithography‐Based Fabrication of Meta‐Chemical Surface for Heavy Metal Detection: Role of Poly‐Methyl Methacrylate in Sensor Sensitivity

open access: yesSmall Science, Volume 5, Issue 2, February 2025.
Meta‐chemical surface (MCS)‐based 1,8‐diaminonaphthalene and MCS‐based D‐penicillamine are being developed as electrochemical sensors by dip‐pen nanolithography. The surface‐to‐volume ratio and the binding strength between the metals and the ligands affect the sensor sensitivity.

Site‐Selective Biofunctionalization of 3D Microstructures Via Direct Ink Writing

open access: yesSmall, Volume 20, Issue 51, December 19, 2024.
A combination of two‐photon lithography with scanning probe lithography is proposed as a new approach for biofunctionalization of 3D microstructures, with spatially controlled biomolecule distribution. The method utilizes a diverse range of biomolecule inks, including phospholipids, and two different proteins, introducing sub‐1 µm resolution and ...

Estimating gear selectivity and population composition of common whelks Buccinum undatum from tagging experiments and comparative gear trials

open access: yesNorth American Journal of Fisheries Management, Volume 44, Issue 3, Page 693-705, June 2024.
Abstract Objective The common whelk Buccinum undatum is of great commercial and ecological importance, but little information is known regarding the gear selectivity of the fishery. Understanding gear selectivity is key for the long‐term sustainability of a stock and has applications in stock assessments and fishery management.

Energy‐Optimized Consensus Formation Control for the Time‐Delayed Bilateral Teleoperation System of UAVs

open access: yesInternational Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018
This paper proposes an energy‐optimized consensus formation scheme for the time‐delayed bilateral teleoperation system of multiple unmanned aerial vehicles (UAVs) in the obstructed environment. To deal with the asymmetric time‐varying delays in aerial teleoperation, the local damping is independently distributed on both sides to enforce consensus ...

Development of Meta‐Chemical Surface by Dip‐Pen Nanolithography for Precise Electrochemical Lead Sensing

open access: yesSmall Methods, Volume 8, Issue 3, March 20, 2024.
In the current article, an electrochemical lead sensor is developed. The sensor is based on a meta‐chemical surface patterned by dip‐pen Nanolithography. The patterned ink includes an NTPH‐PMMA composition. The DPN patterning provides rapid and high‐precision nanoclusters with a high surface‐area‐to‐volume ratio designated for rapid detection of Pb(II)

Nanoscale Confinement of Dip‐Pen Nanolithography Written Phospholipid Structures on CuZr Nanoglasses

open access: yesAdvanced Materials Interfaces, Volume 11, Issue 2, January 16, 2024.
Columnar nanoglasses show a peculiar confinement of phospholipid membranes written by dip‐pen nanolithography. It observes a distinct confinement of spreading in comparison to homogeneous films of the same metal glass, not attributed to roughness. Additionally, ripple‐like membrane states can be observed on columnar nanoglasses.
