Advanced Materials Interfaces, EarlyView., 2023 The conduction band (CB) edge and surface state energy level of TiO2 nanoparticles shift downward with increasing Li+ concentration, which facilitates the charge‐transfer interaction between the molecules and the surface enhanced Raman scattering substrates. Abstract While the Lithium ion modification strategy is widely adopted in tuning the bandgap of

Identification and Reversible Optical Switching of NV+ Centers in Diamond
Advanced Functional Materials, EarlyView.NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Advanced Functional Materials, EarlyView.The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Sparse polynomial multiplication for lattice-based cryptography with small complexity
The Journal of Supercomputing, 2015 In this paper, we propose efficient modular polynomial multiplication methods with applications in lattice-based cryptography. We provide a sparse polynomial multiplication to be used in the quotient ring $$({\mathbb {Z}}/ p{\mathbb {Z}}) [x] / (x^{n}+1)$$(Z/pZ)[x]/(xn+1).

Optical Control of Ferroelectric Imprint in BiFeO3
Advanced Functional Materials, EarlyView.Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...
