Compact and effective photon-resolved image scanning microscope
Fluorescence confocal laser-scanning microscopy (LSM) is one of the most popular tools for life science research. This popularity is expected to grow thanks to single-photon array detectors tailored for LSM. These detectors offer unique single-photon spati ...
Spie-Soc Photo-Optical Instrumentation Engineers2024Label-Free Techniques for Probing Biomolecular Condensates
Aleksandra Radenovic, Wayne Yang Wen Wei, Khalid Ashraf Mohie Ibrahim, Helena Miljkovic, Akhil Sai Naidu
Biomolecular condensates play important roles in a wide array of fundamental biological processes, such as cellular compartmentalization, cellular regulation, and other biochemical reactions. Since their discovery and first observations, an extensive and e ...
Amer Chemical Soc2024Controlling crystal cleavage in focused ion beam shaped specimens for surface spectroscopy
Philip Johannes Walter Moll, Matthias Carsten Putzke, Andrew Scott Hunter
Our understanding of quantum materials is commonly based on precise determinations of their electronic spectrum by spectroscopic means, most notably angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy. Both require atomicall ...
Melville2024Probing Catalytic Sites and Adsorbate Spillover on Ultrathin FeO2-x Film on Ir(111) during CO Oxidation
Harald Brune, Hao Yin, Wei Fang
The spatially resolved identification of active sites on the heterogeneous catalyst surface is an essential step toward directly visualizing a catalytic reaction with atomic scale. To date, ferrous centers on platinum group metals have shown promising pote ...
Washington2024Process-Induced Structures of Injection-Molded High-Density Polyethylene-Combining X-ray Scattering and Finite Element Modeling
Marianne Liebi, Manuel Guizar Sicairos
The success of plastics heavily relies on fast melt processing methods used for large-scale industrial manufacturing, including injection molding. The hierarchical structure of the solid polymer depends on material selection combined with processing condit ...
Amer Chemical Soc2024Scanning Tunneling Microscopy for Molecules: Effects of Electron Propagation into Vacuum
Using scanning tunneling microscopy (STM), we experimentally and theoretically investigate isolated platinum phthalocyanine (PtPc) molecules adsorbed on an atomically thin NaCl(100) film vapor deposited on Au(111). We obtain good agreement between theory a ...
Amer Chemical Soc2024Subsurface fluorescence time-of-flight imaging using a large-format single-photon avalanche diode sensor for tumor depth assessment
Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü, Yichen Feng
Significance: Fluorescence guidance is used clinically by surgeons to visualize anatomical and/or physiological phenomena in the surgical field that are difficult or impossible to detect by the naked eye. Such phenomena include tissue perfusion or molecula ...
Spie-Soc Photo-Optical Instrumentation Engineers2024Nanolithography of the nanocorral structure of chemisorbed oxygen atoms on the graphitic lattice
Kumar Varoon Agrawal, Shaoxian Li
Controlled atomic patterning is an attractive tool to fine tune properties of graphitic lattice. Several O-functionalized derivatives of graphitic lattice have been widely studied, e.g., graphene oxide, reduced graphene oxide, and functionalized carbon nan ...
Oxford2024Revealing the Mechanism Underlying 3D-AFM Imaging of Suspended Structures by Experiments and Simulations
The invention of 3D atomic force microscopy (3D-AFM) has enabled visualizing subnanoscale 3D hydration structures. Meanwhile, its applications to imaging flexible molecular chains have started to be experimentally explored. However, the validity and princi ...
