Engineered Substrate‐Free Small Molecules for Enhanced Raman Scattering and Photothermal Conversion Efficiency

open access: yesAdvanced Science, EarlyView.
A molecular engineering strategy is developed to increase the stacking‐induced intermolecular charge transfer‐enhanced Raman scattering (SICTERS) intensity and photothermal conversion efficiency of electron donor‐acceptor‐donor (D–A–D) molecules. This approach enables to design SICTERS‐mediated photo‐theranostic agents for substrate‐free Raman image ...

Extrapolation of proton-proton cross section to cosmic ray energies using geometrical model

open access: yesEPJ Web of Conferences, 2017
We present a new parameterization of the hadronic matter distribution in the geometrical picture of elastic scattering. Our model contains four free energy-dependent parameters that allows us to propose a better description of differential elastic cross ...

Ultrarelativistic generalized Lorentzian thermodynamics and the differential cosmic ray energy flux

open access: yes, 2017
We apply the ultrarelativistic generalized Lorentzian quasi-equilibrium thermodynamic energy distribution to the energy spectrum of galactic cosmic ray fluxes.

Unlocking the Interaction Mechanism of CNTs and C‐S‐H on Enhancing Elastic and Viscoelastic Properties of Alite Paste

open access: yesAdvanced Science, EarlyView.
This study explores carbon nanotubes’ (CNTs) role in enhancing alite paste’ elasticity and viscoelasticity. Experimental and simulation results reveal that CNTs weakly influence nucleation but significantly refine C‐S‐H gel structure and calcium hydroxide distribution.

Suppressing the QCD axion abundance by hidden monopoles

open access: yesPhysics Letters B, 2016
We study the Witten effect of hidden monopoles on the QCD axion dynamics, and show that its abundance as well as isocurvature perturbations can be significantly suppressed if there is a sufficient amount of hidden monopoles.

Radial oscillations of an electron in a Coulomb attracting field

open access: yesOpen Physics, 2022
The radial motion of an electron in a Coulomb attracting field based on a new theory of the interaction of a particle with an electromagnetic field is studied.

ACCELERATION OF COSMIC RAYS AT COSMIC SHOCKS [PDF]

open access: yesJournal of The Korean Astronomical Society, 2003
Nonthermal particles can be produced due to incomplete thermalization at collisionless shocks and further accelerated to very high energies via diffusive shock acceleration. In a previous study we explored the cosmic ray (CR) acceleration at cosmic shocks through numerical simulations of CR modified, quasi-parallel shocks in 1D plane-parallel geometry ...

Expectations for high energy diffuse galactic neutrinos for different cosmic ray distributions

open access: yes, 2016
The interaction of cosmic rays with the gas contained in our Galaxy is a guaranteed source of diffuse high energy neutrinos. We provide expectations for this component by considering different assumptions for the cosmic ray distribution in the Galaxy ...

Needle‐free, Liquid Metal‐embedded Electrospray Deposition System for Controlled Microdroplet Printing

open access: yesAdvanced Science, EarlyView.
The liquid metal‐embedded electrospray deposition (LM‐ESD) system combines stable droplet spray, clog‐free and recoverable operation, and simplified fabrication in a single polydimethylsiloxane (PDMS) microfluidic platform. By eliminating external electrodes, it offers needle‐free, robust, and scalable droplet array printing, ensuring reproducibility ...
