Laser-scanning reflection-matrix microscopy for myelin imaging through intact mouse skull 2020 ABC myelinthrough intact mouse skullJin Hee Hong1,2, Seokchan Yoon1,2, Hojun Lee1,2, Yong-Sik Lim3 and Wonshik Choi1,2 We present a laser-scanning reflection-matrix microscopy (LS-RMM) that can correct sample-induced aberrations for up to 10,000 angular modes. LS-RMM combines the scanning of a laser focus and wide-field detection of electric ... RegDate 2022-05-30 Hit 1590
Deep-Tissue Super-Resolution Microscopy using Single-Scattering Accumulation Algorithm ABC 2020 AbstractSingle-molecule localization microscopy has enabled the resolving of biomolecules well beyond the diffraction-limited spatial resolution. However, its imaging depth has been too shallow to investigate thick biological tissues. A sample-induced aberration is one of the major reasons for this limitation. It gives rise to the blur and ...

In-operando Raman Spectroscopic Studies of the Coloring and Bleaching Mechanism of Self-powered Photoelectrochromic Devices 2020 KECS Spring Meeting The chromogenic material, which have various applications in smart windows and glasses, reversibly change their color when electrons and cations are injected by applied voltage or absorption of light. Especially, electrochromic devices (ECDs) have been studied in many studies to utilize as switchable windows, however, it is... RegDate 2022-04-20 Hit 1544
Solvation Structure study of Lithium-Ion Battery Electrolytes by FTIR and PFG-NMR spectroscopy 2020 KECS Spring Meeting Abstract: Lithium ion batteries are relevant to a wide range of portable electronic device due to high charge density of lithium ion among other materials. The performance of lithium ion in the lithium ion batteries depends on the choice of the medium for lithium ion electrolytes. Electrolytes play a role in ion dissociation...

Shot-Noise-Limited Two-Color Stimulated Raman Scattering Microscopy 125th KCS AbstractStimulated Raman scattering (SRS) microscopy has been regarded as a useful technique to investigate chemical components by selectively targeting vibrational modes of chemical structures. In applications of observing molecular environments and dynamics in complex biological environments, both high signal-to-noise ratio and spectral... RegDate 2022-01-14 Hit 1666
Interferometric Scattering Microscopy to Characterize Nanometric Objects and Subcellular Structures: Towards Fast 3D Imaging at Nanoscale. BPS2020 It is of great interest to visualize nano-scale (biological) objects in both nano- and bio-science. Several ingenious methods such as fluorescence-based super-resolution microscopic techniques have been developed to meet the need. These techniques, however, bear evident limitations in measurement time, time resolution, and sample preparation... RegDate 2021-10-07 Hit 2158
Dual frequency comb vibrational optical activity spectroscopy 2019 124th KCS General Meeting It is of great importance to develop techniques to measure optical activity when we investigate biomolecules. Since CD is a extremely weak value, time-resolved CD spectroscopy is experimentally challenging. Here, we demonstrated that it is possible to measure electronic optical activity free-induction-decay (OA-FID) fie... RegDate 2021-08-12 Hit 1710
Lithium-Ion Battery Solvation Structure study at low temperature with Cryostat 2019 124th KCS General Meeting There are many problems with current lithium-ion batteries that are discharged in unexpected cold due to climate change and in the polar regions. Although many groups are trying to improve the temperature range of LIB, studies have limitations since there is no exact understanding of the molecular level of LIB’s solva...

In situ layered double hydroxide (LDH) catalyst study using Sum-frequency generation spectroscopy 2019 124th KCS General MeetingAbstract: Water oxidation is an essential reaction for energy storage such as forming of hydrogen or hydrocarbons without accumulation of by-product. Unfortunately, This reaction is consist of a complex multistep, which adds a considerably large overpotential to the actual process. Although many studies have been conducte...

Two-dimensional Analysis of Femtosecond-to-Nanosecond Molecular Dynamics with Dual Frequency-Comb 2DES TRVS 2019 Two-dimensional electronic spectroscopy (2DES) has been widely used for studying ultrafast energy transfer processes in multi-chromophoric systems. Compared to other time-resolved spectroscopic techniques, the additional excitation-frequency resolvability of 2DES provides far more detailed information on reaction pathway and inhomogeneity o...

Wide –field Laser Scanning Microscopy for Imaging through The Intact Skull Imaging in Wave Physics Multi-Wave and Large Sensor Networks 2019 Abstract: We present a novel non-fluorescence-based adaptive-optics optical coherence tomography that can eliminate higher-order aberrations even in the regime of strong multiple scattering of light. With this technique, we demonstrate in vivo high-resolution reflectance imaging of coll... RegDate 2021-04-27 Hit 1897
Label-free deep-tissue imaging in vivo using adaptive optical synchronous angular scanning microscopy Imaging in Wave Physics Multi-Wave and Large Sensor Networks 2019 Abstract: Light waves propagating in biological tissues undergo wavefront distortion because of spatial heterogeneity of anatomical structure and cellular distribution, etc. This results in blurring of an optical focus and the reduction of the resolving power. We propose label-free adap... RegDate 2021-04-27 Hit 1856
