Binary and Ternary Anisotropic Core-Shell Nanosandwiches with Composition Tunable Core for Oxygen Evolution Reaction 2018 MRS Development of electrocatalysts with reduced noble metal content with enhanced catalytic performance has been of importance in cost-effective design of renewable energy conversion devices. The design of core-shell nanoparticles as electrocatalysts represents a promising approach for preparing not only limiting the use of expensive precious m... RegDate 2019-12-13 Hit 1915
Synthesis of Hollow Cobalt/Nickel Sulfide Octahedral Nanocages and Their Composition-Dependent Electrocatalytic Activities for Oxygen Evolution Reaction 2018 MRS Hollow nanostructures such as nanocages and nanoframes can serve as advanced catalysts with their enlarged active surface areas, and hence they have been of widespread interest. Despite the recent progress in the synthesis of this class of nanomaterials, hollow nanostructures with tunable compositions and controlled morphologies have rarely ... RegDate 2019-12-13 Hit 1940
Cactus like Cu2-xS@IrSy@IrRu alloy nanoparticles as highly efficient bifunctional electrocatalysts for overall water splitting in acidic media 2018 MRS Bifunctional electrocatalysts for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) is mandatory for clean and sustainable alternative energy sources. To improve the efficiency of the overall water splitting, highly efficient and stable bifunctional electrocatalysts in acidic media is vital for polymer electrolyte... RegDate 2019-12-03 Hit 2324
Cyanamide as an Infrared Reporter: Comparison of Vibrational Properties between Nitriles Bonded to N and C Atoms 2018 121st KCS General Meeting β-cyanamidoalanine 1 and p-cyanamidophenylalanine 2 were synthesized. The vibrational properties of their CN stretch mode were studied using FTIR and femtosecond IR pump−probe spectroscopies. Aromatic cyanamide 2 shows a complicated lineshape of the FTIR spectrum, which arises from the accidental Fermi resonance, and... RegDate 2019-11-28 Hit 1871
The study of Azide probes : Comparison of primary, secondary and aromatic series 2018 121st KCS General Meeting As IR probe of side chain dynamics, the azide group has been used as local environmental probe. It is useful study of dynamics and structure. It has been found that azide probe has large extinction coefficient. It means that it has the potential to make low concentration protein samples. However, It has weak point like ... RegDate 2019-11-28 Hit 1862
The vibrational studies on the water channel in LiTFSI aqueous electrolyte system 2018 121st KCS General Meeting Abstract: The highly concentrated LiTFSI(Lithium bis(trifluoromethanesulfonyl)imide) aqueous electrolyte overcome the electrochemical stability window of water(1.23 V) due to the formation of SEI that was not found in other aqueous solutions. This particular property presents the possibility of this electrolyte as a rep... RegDate 2019-11-28 Hit 1863

Spectroscopic Study on Photodegradation of PTB7-Th 2018 121st KCS General Meeting Organic photovoltaic(OPV) is in the spotlight as a component of solar cell because of its lower cost fabrication and better processability compared with existing silicon. Materials of OPV have been studied to improve power conversion efficiency(PCE) and PTB7-Th polymer is suitable to gain high PCE. However, photodegradat... RegDate 2019-11-28 Hit 1867
Label-free Microscopy Using Vibrational Resonance by Stimulated Raman Scattering 2018 121st KCS General MeetingAbstract: Bio-molecular imaging has great importance, since it would be most reliable way to understand the functions and physiology of cells and the pathophysiology of disease. Monitoring cellular process is challenging, for its fast physiological and biochemical dynamics as well as nano-scale spatial dimensions. Moreover... RegDate 2019-11-13 Hit 1849
Raman and Fluorescence Imaging with Polymer Dot 2018 121st KCS General MeetingRaman scattering is an emerging contrast mechanism for biological imaging due to its narrow spectral bandwidth. However, the sensitivity is many orders of magnitude lower than that of fluorescence. Fluorescence offers extremely high sensitivity, but suffers from broad absorption and emission spectra. Since Raman and fluore... RegDate 2019-11-13 Hit 2138
Site-specific Labeling an Intracellular Protein with Unnatural Amino Acids by Genetic Code Expansion for Spectroscopy and Imaging 2018 121st KCS General MeetingFluorescence imaging is one of the major ways to study the intracellular distribution, structure and function of proteins. Labeling of a protein of interest with a fluorescent probe is often accomplished by organic dyes conjugated to antibodies specific to the protein or genetic incorporation of fluorescence protein fused ...

High-resolution adaptive optical imaging within thick scattering media using closed-loop accumulation of single scattering 2018 FOM 1. Abstract When considering a target spatial resolution close to the ultimate diffraction limit, the attenuation of SNR by multiple light scattering is not the only problem. In fact, the specimen-induced aberration is an equally important issue to address [1]. The signal waves that preserve original incidence momenta are not only attenuate... RegDate 2019-11-13 Hit 1708
