Dual frequency comb spectroscopy for optical activity measurement 2019 123rd KCS Most of biomolecules and medicines has optical activity, such as circular dichroism(CD) and optical rotation dispersion(ORD). Therefore, it is of great importance to develop techniques to investigate optical activity. Since CD is a extremely weak value, time-resolved CD spectroscopy is experimentally challenging. Here, we demonstrated t... RegDate 2020-04-22 Hit 1669
Ultrafast Infrared Spectroscopy Study of Azides with β-isotope labeling: Comparing with Aliphatic Azides and Aromatic Azides 2019 123rd KCS Azides can be used as infrared (IR) probes of the local environment and molecular structural changes. The dynamics reported by a site-specific IR probe is limited to its vibrational lifetime, restricting the utility of azide probes due to short vibrational lifetimes. Moreover, the vibrational bands of azide probes are often accompanied ... RegDate 2020-04-22 Hit 1692
The Li ion battery’s electrolyte solvation dynamics in operando condition near the electrode 2019 123rd KCS Electrolyte is one of the main components of lithium ion batteries, which acts as transport channels for lithium ions and is closely related to battery performance such as charge rate, capacitance, stability, and safety. Since the performance of these batteries is determined by the microscopicproperties of solvent molecules or lithium... RegDate 2020-04-22 Hit 1652
Do Osmolytes Impact the Structure and Dynamics of Myoglobin? 2019 123rd KCS Typical pulse width of mid-IR pulse generated by OPA-dfg is limited to 200-400 cm-1 which is not enough to cover whole molecular vibration region. Generation of continuum IR pulse is useful for time-resolved spectroscopy since it makes possible to observe entire vibration region with single shot. This useful broadband pulse was generat...

Network structure and dynamics of hydration water at zwitterionic lipid membrane surfaces 2019 123rd KCS Lipid bilayer is an excellent model system for investigating membrane structures and its hydration water. These membrane and hydration water have been studied by various experiments and computational studies. To observe detailed interactions between lipid head groups and their hydration water, we performed molecular dynamics (MD) simul... RegDate 2020-04-22 Hit 1584
Time-resolved spectroscopy with two frequency-stabilized mode-locked lasers 2019 123rd KCS Femtosecond laser has brought a dramatic development on time-resolved spectroscopy to understand the complex photochemical reactions in nature. In time-resolved spectroscopy, an impulsive pump pulse generates a non-equilibrium state, and its time evolution is monitored by a probe pulse. The time delay between the pump and probe is gen...

The long-range correlations of time-resolved speckle patterns 2019 Light in Complex Materials WORKSHOPAbstract: Recently we were able to deliver light energy to the objects embedded in a disordered medium by coupling incident light into time-resolved reflection eigenchannels that control the transmittance or reflectance due to the interference between waves experiencing multiple scattering in disordered media. It... RegDate 2020-03-31 Hit 1711
Focusing of light energy inside a scattering medium using time-gated reflection eigenchannel 2019 Light in Complex Materials WORKSHOP For non-invasive optical imaging, sensing, and stimulation of target objects embedded deep within a scattering medium, it is essential to deliver light waves to target objects efficiently. However, multiple light scattering induces random wave diffusion and drastically limits the light waves reaching the target obj... RegDate 2020-03-31 Hit 1534
