Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

Higgs/amplitude mode dynamics from holography

Journal of High Energy Physics, 2022
Second order phase transitions are universally driven by an order parameter which becomes trivial at the critical point. At the same time, collective excitations which involve the amplitude of the order parameter develop a gap which smoothly closes to ...

Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

Advanced Materials, Volume 38, Issue 11, 20 February 2026.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

Holographic hydrodynamics of tilted Dirac materials

Journal of High Energy Physics, 2023
We present a gravity dual to a quantum material with tilted Dirac cone in 2+1 dimensional spacetime. In this many-body system the electronics degrees of freedom are strongly-coupled, constitute a Dirac fluid and admit an effective hydrodynamic ...

In Situ Liquid‐Cell Transmission Electron Microscopy Insights Into Lithium‐Ion Battery Materials Degradation: Challenges and Emerging Solutions

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Lithium‐ion battery degradation arises from complex, localized processes during operation, limiting long‐term performance. In situ electrochemical liquid cell TEM provides unique access to these mechanisms. This review summarizes degradation phenomena revealed by liquid cell TEM, traces the evolution of the three main cell designs, compares their ...

Dynamical stability from quasi normal modes in 2nd, 1st and 0th order holographic superfluid phase transitions

Journal of High Energy Physics, 2023
We study a simple extension of the original Hartnoll, Herzog and Horowitz (HHH) holographic superfluid model with two nonlinear scalar self-interaction terms λ|ψ|4 and τ|ψ|6 in the probe limit.

Analysis of Giant‐Shell CdSe/CdS Quantum Dots via Analytical Ultracentrifugation Combined with Spectrally Resolved Photoluminescence

Small Methods, Volume 10, Issue 2, 22 January 2026.
Analytical ultracentrifugation (AUC) is a powerful tool for studying the size–property relationships of nanomaterials in their native environment. A methodology based on AUC with in‐line multiwavelength emission detection is developed, enabling the measurement of the size‐resolved emission spectra of giant‐shell CdSe/CdS quantum dots.

Black brane entropy and hydrodynamics

, 2010
A generalization of entropy to near-equilibrium phenomena is provided by the notion of a hydrodynamic entropy current. Recent advances in holography have lead to the formulation of fluid-gravity duality, a remarkable connection between the hydrodynamics ...
