Advanced Functional Materials, EarlyView.In this work, we use direct ink writing (DIW) to 3D print Bi2Te3‐based materials and naturally induce hierarchical functional nanostructures, which reduced the lattice thermal conductivity by half, resulting in high zT of 0.87and 0.89 in p‐type and n‐type compounds, respectively, competitive with commercial materials.

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus
Advanced Healthcare Materials, EarlyView.This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...

*-Ricci soliton on (κ, μ)′-almost Kenmotsu manifolds
Open Mathematics, 2019 Let (M, g) be a non-Kenmotsu (κ, μ)′-almost Kenmotsu manifold of dimension 2n + 1. In this paper, we prove that if the metric g of M is a *-Ricci soliton, then either M is locally isometric to the product ℍn+1(−4)×ℝn or the potential vector field is ...

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives
Advanced Materials, EarlyView.Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Advanced Materials, EarlyView.Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Nearly Sasakian manifolds revisited
Complex Manifolds, 2019 We provide a new, self-contained and more conceptual proof of the result that an almost contact metric manifold of dimension greater than 5 is Sasakian if and only if it is nearly Sasakian.

A dimensional restriction for a class of contact manifolds
Demonstratio Mathematica, 2017 In this work we consider a class of contact manifolds (M, η) with an associated almost contact metric Structure (ϕ, ξ, η, g). This class contains, for example, nearly cosymplectic manifolds and the manifolds in the class C9 ⊕ C10 defined by Chinea and ...
