Universal Behaviors of Speed of Sound from Holography

, 2017
We investigate the speed of sound in $(d+1)$-dimensional field theory by studying its dual $(d+2)$-dimensional gravity theory from gauge/gravity correspondence.

Condensed matter applications of the Gauge/Gravity correspondence

, 2014
In this thesis, we investigate non-perturbative features of strongly coupled condensed matter systems, generically, placed at finite temperature, charge density and, possibly, in a magnetic field using the theoretical framework of the gauge/gravity correspondence.

Fluoride‐Free Molten Salt Hydrate‐Assisted Synthesis of MXene in Air Down to 150 °C

Advanced Functional Materials, EarlyView.
A novel low‐temperature shielded salt (LSS) approach enables the synthesis of MXenes in air at temperatures as low as 150 °C using MgCl2·6H2O/LiCl. This method demonstrates successful etching of challenging MXenes like Cr2CTx and Nb2CTx through the synergistic effects of Li+ ions and salt hydrate phase changes, while eliminating the need for inert ...

Holographic complexity and noncommutative gauge theory

Journal of High Energy Physics, 2018
We study the holographic complexity of noncommutative field theories. The four-dimensional N = 4 $$ \mathcal{N}=4 $$ noncommutative super Yang-Mills theory with Moyal algebra along two of the spatial directions has a well known holographic dual as a type

Highly Sensitive Cuffless Blood Pressure Monitoring with Selective Laser‐Sintered Liquid Metal Conductors

Advanced Functional Materials, EarlyView.
A soft, compact, and cuffless system for continuous blood pressure monitoring using laser‐sintered liquid metal conductors is developed. The stretchability and sensitivity of the device enable real‐time, non‐invasive tracking of blood pressure, including recovery after exercise. This wearable device offers a practical solution for managing hypertension

On the chaos bound in rotating black holes

Journal of High Energy Physics, 2019
We study out-of-time-order correlators (OTOCs) of rotating BTZ black holes using two different approaches: the elastic eikonal gravity approximation, and the Chern-Simons formulations of 3-dimensional gravity.

A Universal Way to Manipulate Droplet via Light‐Fueled Thermocapillary Convection

Advanced Functional Materials, EarlyView.
A non‐contact light‐induced droplet manipulation strategy fueled by mid‐infrared (MIR) light irradiation is introduced. No additional additives and/or complex substrate are required. Here, thermocapillary convection, directly generated by temperature gradient at outer surface of droplet via localized surface heating, plays a key role to propel the ...

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Polymer‐Incorporated Mechanically Compliant Carbon Nanotube Microelectrode Arrays for Multichannel Neural Signal Recording

Advanced Functional Materials, EarlyView.
This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.
