Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Hyperspectral Meets Optical Flow: Spectral Flow Extraction for Hyperspectral Image Classification

IEEE Transactions on Image Processing, 2023
Hyperspectral image (HSI) classification has always been recognised as a difficult task. It is therefore a research hotspot in remote sensing image processing and analysis, and a number of studies have been conducted to better extract spectral and ...

The evolution of spectral flow cytometry

Cytometry Part A, 2022
This special issue of Cytometry marks the transition of spectral flow cytometry from an emerging technology into a transformative force that will shape the fields of cytometry and single‐cell analysis for some time to come.

Spectral Simulation of Supersonic Reactive Flows

SIAM Journal on Numerical Analysis, 1998
The authors present a Chebyshev collocation scheme for the numerical simulation of reactive flows with shock waves. It is shown that spectral methods are suitable for the numerical approximation of reactive flows interacting with shock waves. Theoretical and numerical results on interactions of hydrogen jets with shock waves are analyzed, and ...

Nodal deficiency, spectral flow, and the Dirichlet-to-Neumann map

Letters in Mathematical Physics, 2018
It has been recently shown that the nodal deficiency of an eigenfunction is encoded in the spectrum of the Dirichlet-to-Neumann operators for the eigenfunction’s positive and negative nodal domains. While originally derived using symplectic methods, this

Spectral flow for skew-adjoint Fredholm operators

Journal of Spectral Theory, 2016
An analytic definition of a $\mathbb{Z}_2$-valued spectral flow for paths of real skew-adjoint Fredholm operators is given. It counts the parity of the number of changes in the orientation of the eigenfunctions at eigenvalue crossings through $0$ along ...
