Tunable Sensitivity in PAN/CNF/PEDOT:PSS Nanofiber‐Based Piezocapacitive Sensors
Advanced Materials Interfaces, EarlyView.This study demonstrates highly tunable, flexible pressure sensors made from a nanofibrous composite of polyacrylonitrile (PAN) and carbon nanofibers (CNF) or poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). By adjusting filler type, concentration, and mat thickness, the sensors achieve large sensitivity improvements, stable ...

Topological defects in K3 sigma models
Journal of High Energy PhysicsWe consider the topological defect lines commuting with the spectral flow and the N $$ \mathcal{N} $$ = (4, 4) superconformal symmetry in two dimensional non-linear sigma models on K3.

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers
Advanced Materials Technologies, EarlyView.Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Topological lax comma categories
This paper investigates the interplay between properties of a topological space $X$, in particular of its natural order, and properties of the lax comma category $\mathsf{Top} \Downarrow X$, where $\mathsf{Top}$ denotes the category of topologicalspaces and continuous maps. Namely, it is shown that, whenever $X$ is a topological $\bigwedge$-semilattice,

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization
Advanced Materials Technologies, EarlyView.An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on
