2D Hierarchical Black Phosphorus‐Mn2O3 Heterostructured Composites for High‐Performance Flexible Supercapacitors

open access: yesAdvanced Materials Interfaces, EarlyView.
A sonochemical strategy constructs an ex situ 2D hierarchical black phosphorus–Mn2O3 heterostructure, enabling intimate interfacial coupling, enhanced charge transport, and improved electrochemical stability. The optimized BPM‐37.5% electrode delivers 466 F g−1 with 84% retention after 8000 cycles, while the flexible device exhibits high areal energy ...

Contributions To Differential Geometry Of Pseudo Null Curves In Semi-Euclidean Space

open access: yes, 2008
In this paper, first, a characterization of spherical Pseudo null curves in Semi-Euclidean space is given. Then, to investigate position vector of a pseudo null curve, a system of differential equation whose solution gives the components of the position vector of a pseudo null curve on the Frenet axis is established by means of Frenet equations ...

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Inextensible flows of partially null and pseudo null curves in semi-Euclidean 4-space with index 2

open access: yesNovi Sad Journal of Mathematics, 2016
Summary: In this paper, we consider the inextensible flows in semi-Euclidean 4-space with index \(2 (\mathbb E^4_2)\). We give the necessary and sufficient conditions for the flow to be inextensible and we find the evolution equations for the inextensible flows in semi-Euclidean 4-space with index \(2 (\mathbb E^4_2)\).

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

CANAL HYPERSURFACES GENERATED BY NON-NULL CURVES IN LORENTZ-MINKOWSKI 4-SPACE

open access: yes, 2023
In the present paper, firstly we obtain the general expression of the canal hypersurfaces that are formed as the envelope of a family of pseudo hyperspheres, pseudo hyperbolic hyperspheres and null hypercones whose centers lie on a non-null curve with ...

Functional Disorder at the Neural Interface: How Disordered Nanostructures Promote Proper Growth and Differentiation in In Vitro Neural Cultures

open access: yesAdvanced Science, EarlyView.
This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...
