Imaging Electric Polarization Switching in Multilayer Graphene
Advanced Science, EarlyView.Domain wall sliding‐induced electric polarization switching is directly observed for the first time in multilayer graphene, enabled by a novel optical readout method. The polarization switching is realized upon application of global and local electric fields, and mechanical forces between neighboring polar domains of opposite out‐of‐plane polarizations

Ultra‐Thin and Highly Insulating Aromatic Monolayers by N‐Heterocyclic Carbenes
Angewandte Chemie, EarlyView.By using N‐heterocyclic carbenes extremally insulating and at the same time as thin as 0.3 nm molecular films are formed. The charge transport calculations indicate absence of destructive quantum interference effect which was so far the only way to suppress conductivity in aromatic molecules.

The rise and fall of little red dots could be driven by the environment
Astronomy & AstrophysicsThe little red dot (LRD) paradigm comprises three main unknowns that are intrinsically connected: (1) What is the nature of these sources? (2) How do they form? (3) How do they evolve?

Advanced Science, EarlyView.This work proposes and constructs the Hefei‐NAMD‐S framework based on machine learning stacked models to investigate the relationship between local polarization and non‐radiative recombination. The results indicate that, compared with A‐site local polarization, B‐site local polarization shows a more evident association with the non‐radiative ...

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Advanced Electronic Materials, EarlyView.Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

Probabilistic Neural Network Approach to Determining Parameters of Eclipsing Binaries
The Astronomical JournalEclipsing binaries provide one of the most direct mechanisms for measuring stellar properties such as mass and radius, but determining these properties has historically been nontrivial and computationally prohibitive.
