Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Matlab Applications for Skew-Symmetric Matrices and Integral Curves in Lorentzian Spaces

Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2017
In [8], the authors obtained the non-zero solutions of the equation A(x)=0, in Lorentzian space where A is a skew-symmetric matrix corresponding to the linear map A and got normal forms of the skew-symmetric matrix A, depending on the causal characters ...

Adaptive Clustering via Symmetric Nonnegative Matrix Factorization of the Similarity Matrix

Algorithms, 2019
The problem of clustering, that is, the partitioning of data into groups of similar objects, is a key step for many data-mining problems. The algorithm we propose for clustering is based on the symmetric nonnegative matrix factorization (SymNMF) of a ...

Symmetric matrix pencils

Journal of Computational and Applied Mathematics, 1991
Typical matrix eigenvalue problems, quadratic or linear, are best formulated as pencils \((A,M)\) in which both \(A\) and \(M\) are real and symmetric. This fact is emphasized in the paper through a set of physical examples. Then, the canonical forms are used to explain the role of the sign characteristic attached to real eigenvalues.

Tailored Polymer‐Based SEI via iCVD for Stable Zinc Metal Anodes in Aqueous Batteries through Modulation of Hydrophilicity and Elasticity to Inhibit Hydrogen Evolution Reactions

Advanced Functional Materials, EarlyView.
A stretchable and superhydrophobic pF1V1 polymer layer is conformally coated on Zn metal via iCVD, forming a water‐repelling interphase that inhibits the hydrogen evolution reaction. This tailored interface maintains excellent electrolyte compatibility while suppressing dendrite growth, thereby enhancing the long‐term electrochemical stability of Zn ...

A note on the growth factor in Gaussian elimination for generalized Higham matrices

, 2013
The Higham matrix is a complex symmetric matrix A=B+iC, where both B and C are real, symmetric and positive definite and $\mathrm{i}=\sqrt{-1}$ is the imaginary unit. For any Higham matrix A, Ikramov et al.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations
