Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Noncommutative Topology and Prospects in Index Theory

, 2016
This article is a tribute to the memory of Professor Enzo Martinelli, with deep respect and reconesance. Nicolae Teleman. The index formula is a local statement made on global and local data; for this reason we introduce local Alexander - Spanier co-homology, local periodic cyclic homology, local Chern character and local $T^{\ast}$-theory.

Topological Rough Groups

, 2016
The concept of topological group is a simple combination of the concepts of abstract group and topological space. The purpose of this paper is to combine the concepts of topological space and rough groups; called topological rough groups on an ...

Proximity‐Tuned Magnetic and Transport Anomalies in All‐Epitaxial Fe5−xGeTe2/WSe2 Van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

Advanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

Advanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...

Choosing the exponent in the definition of the connectivity index [PDF]

Journal of the Serbian Chemical Society, 2001
Let du denote the degree of the vertex u of a molecular graph G. Then the connectivity index of G is defined as C (l) = G (l; C) = S (dudu)l, where the summation goes over all pairs of adjacent vertices. The exponent l is usually chosen to be equal to –1/

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological
