Molecular intercalation in the van der Waals antiferromagnets FePS3 and NiPS3

Bruce Normand, Xiaoyu Xu, Sheng Xu, Ying Chen, Zeyu Wang, Shuo Li, Weiqiang Yu

We have performed electrochemical treatment of the van der Waals antiferromagnetic materials FePS3 and NiPS3 with the ionic liquid EMIM-BF4, achieving significant molecular intercalation. Mass analysis of the intercalated compounds, EMIMx-FePS3 and EMIMx-N ...

A synchrotron X-ray imaging strategy to map large animal brains

Giorgio Margaritondo, Ying Chen

Mapping the large neural networks of animal and human brains is a fundamental but so far elusive task, because of the massive amount of data and the consequent prohibitively long image taking and processing times. We developed an effective strategy called ...

Gold nano-mesh synthesis by continuous-flow X-ray irradiation

Giorgio Margaritondo, Ying Chen

X-ray irradiation has been extensively used in recent years as a fabrication step for nanoparticles and nanoparticle systems. A variant of this technique, continuous-flow X-ray irradiation, has recently been developed, and offers three important advantages ...

Free-electron-laser coherent diffraction images of individual drug-carrying liposome particles in solution

Giorgio Margaritondo, Ying Chen, Ke Peng

Using the excellent performances of a SACLA (RIKEN/HARIMA, Japan) X-ray free electron laser (X-FEL), coherent diffraction imaging (CDI) was used to detect individual liposome particles in water, with or without inserted doxorubicin nanorods. This was possi ...

Single cell isolation process with laser induced forward transfer

Philippe Renaud, Yu Deng, Ying Chen

Background A viable single cell is crucial for studies of single cell biology. In this paper, laser-induced forward transfer (LIFT) was used to isolate individual cell with a closed chamber designed to avoid contamination and maintain humidity. Hela cells ...

Optimization of Gold Nanoparticle Photoluminescence by Alkanethiolation

Giorgio Margaritondo, Ying Chen

Surface thiolation was recently found to affect two important properties of gold nanoparticles: their size and the presence of visible luminescence under UV stimulation. We explored these phenomena by systematically analysing alkanethiolate coatings with d ...

X-ray-induced Cu deposition and patterning on insulators at room temperature

Giorgio Margaritondo, Ying Chen

X-ray irradiation is shown to trigger the deposition of Cu from solution, at room temperature, on a wide variety of insulating substrates: glass, passivated Si, TiN/Ti/SiO2/Si and photoresists like PMMA and SU-8. The process is suitable for patterning and ...

Uncapped Au-Pd colloidal nanoparticles show catalysis enhancement

Giorgio Margaritondo, Ying Chen

The catalytic properties of Pd trigger a strong interest on the related catalysis by Au-Pd nanoparticles. However, the analysis of such phenomena was complicated so far by the presence of capping. Using x-ray irradiation, we could produce uncapped Au-Pd na ...

A compact synchrotron-based transmission X-ray microscope

Giorgio Margaritondo, Ying Chen

A compact transmission X-ray microscope has been designed and implemented based on a cylindrical symmetry around the optical axis that sharply limits the instabilities due to thermal mechanical drift. Identical compact multi-axis closed-loop actuation modu ...
