Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

open access: yesAdvanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Stereochemical configuration of molecular additives greatly influences interfacial adsorption at the Zn surface. The optimal tilted dual‐anchored adsorption geometry of myo‐inositol constructs a water‐deficient interface and regulates the solvation structure.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Metal magnetic memory effect caused by circle tensile-compressive stress

Insight: Non-Destructive Testing and Condition Monitoring, 2011
The variation of surface magnetisation, caused by applied stress under the geomagnetic field, can be potentially used to evaluate the degree of fatigue damage for ferromagnetic materials. Under lab conditions, the normal components of surface magnetisation induced by circle tensile-compressive stress are measured in rotary bending fatigue experiments ...

Equilibrium and symmetries of altitudinal magnetic rotors on a circle

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Macroscopic magnets can easily be manipulated and positioned so that interactions between themselves and with external fields induce interesting dynamics and equilibrium configurations. In this work, we use rotating magnets positioned in a line or at the vertices of a regular polygon. The rotation planes of the magnets can be modified at will. The rich

Magnetic Arctic Circle in a Square Ice Qubit Lattice

Physical Review Letters, 2023
Under certain boundary conditions, the square ice model exhibits a phase separation in which the core of the system is disordered while its outer region remains ordered. This phenomenon, known as the "arctic circle," has been studied theoretically in combinatorial mathematics and statistical mechanics.
