Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

open access: yesAdvanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Integrity basis for a second-order and a fourth-order tensor

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
In this paper a scalar-valued isotropic tensor function is considered, the variables of which are constitutive tensors of orders two and four, for instance, characterizing the anisotropic properties of a material.

The Characteristic Polynomial And Its Applications

open access: yes
This dissertation examines some applications of the characteristic polynomial \[Q_A(z):=\det (z_0I+z_1A_1+\cdots+z_nA_n),\] where $A_0,\dots,A_n$ are complex square matrices and $(z_0,\dots,z_n)\in\mathbb{C}^{n+1}$.

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

open access: yesAdvanced Materials, EarlyView.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Machine Learning Accelerated Computational Design of Bio‐Inspired Catalysts in the Nitrogen Reduction Reaction

open access: yesAdvanced Materials, EarlyView.
We introduce a computational workflow that combines quantum chemical calculations and machine learning techniques to predict the catalytic performance of a wide range of catalysts in the nitrogen reduction reaction (NRR). The analysis of the trained models provides insights into the complex structure–activity relationship in experimental catalytic ...

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays

open access: yesAdvanced Materials, EarlyView.
An inkjet‐printed liquid crystal droplet array enables compact, low‐cost, single‐shot sensing of the full vectorial light field. Within a single platform, it simultaneously retrieves intensity, polarization, and phase, while dual‐wavelength operation highlights its capability for multi‐wavelength optical field characterization. ABSTRACT Determining the

Characteristic polynomials of a permutation representation

open access: yesJournal of Combinatorial Theory, Series A, 1979
AbstractLet G be a finite group. To each permutation representation (G, X) of G and class function χ of G we associate the χ-characteristic polynomial gχ(x) of (G, X) which is a polynomial in one variable with complex numbers as coefficients. The coefficients of gχ(x) are investigated in terms of the “exterior powers” of (G, X).
