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

Advanced 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,

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

Advanced 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

Advanced 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

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

Advanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Pseudoharmonic maps from nondegenerate CR manifolds to Riemannian manifolds

, 2001
We study pseudoharmonic maps from a strictly pseudoconvex CR manifold $(M, \theta)$ into a Riemannian manifold $(N, h)$, i.e. critical points of the energy functional $E(\varphi )= \frac{1}{2} \int_M \mathrm{trace}_{G_\theta} ( \pi_H \varphi^* h )\theta
