2D Borophene: In‐Plane Hyperbolic Polaritons in the Visible Spectral Range

Advanced Functional Materials, EarlyView.
Researchers have synthesized the χ3 phase of borophene, a 2D metal, using chemical vapor deposition. Combining theory and deep‐subwavelength spectroscopy, they uncover borophene's unique anisotropic optical behavior in the visible range. This breakthrough paves the way for advanced optoelectronic devices using borophene‐based heterostructures ...

Dynamical System-Based Computational Models for Solving Combinatorial Optimization on Hypergraphs

IEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2023
The intrinsic energy minimization in dynamical systems offers a valuable tool for minimizing the objective functions of computationally challenging problems in combinatorial optimization. However, most prior works have focused on mapping such dynamics to

Interface Topology Driven Loss Minimization in Integrated Photonics: THz Ultrahigh‐Q Cavities and Waveguides

Advanced Materials, EarlyView.
Compact, robust, and ultralow‐loss on‐chip photonic devices are essential for densely integrated photonic chips. Here, the underlying radiation mechanism in topological valley edge states is unveiled and a new methodology of interface topology driven bandgap and wavevector engineering is proposed to thoroughly suppress their radiation losses, thereby ...

Factorization of singular integer matrices

Linear Algebra and its Applications, 2008
AbstractIt is well known that a singular integer matrix can be factorized into a product of integer idempotent matrices. In this paper, we prove that every n × n (n>2) singular integer matrix can be written as a product of 3n+1 integer idempotent matrices. This theorem has some application in the field of synthesizing VLSI arrays and systolic arrays.

Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation

Advanced Materials, EarlyView.
The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...

An analogue in certain unique factorization domains of the Euclid-Euler theorem on perfect numbers

International Journal of Mathematics and Mathematical Sciences, 1990
We show that there exists a natural extention of the sum of divisors function to all unique factorization domains F having a finite number of units such that if a perfect number in F is defined to be an integer η whose proper divisors sum to η, then the ...

Unveiling the Effects of Hydroxyl‐Induced Trap States on the Charge Transport in p‐ and n‐Channel Organic Field‐Effect Transistors through Variable‐Temperature Characterization

Advanced Materials, EarlyView.
A full high vacuum preparation and characterization chain unveils that hydroxyl‐induced trap states affect the charge transport in p‐ and n‐channel OFETs similarly. The variable‐temperature TLM analysis suggests that the activation energy of charge transport plays a more significant role than the density of trap states.

A New Secure Encryption Scheme Based on Group Factorization Problem

IEEE Access, 2019
As special types of factorization of finite groups, logarithmic signatures and covers have been used as the main components of cryptographic keys for secret key cryptosystems such as $PGM$ and public key cryptosystems like $MST_{1}$ , $MST_{2 ...

Automatic Exposure Volumetric Additive Manufacturing

Advanced Materials Technologies, EarlyView.
Tomographic volumetric additive manufacturing (VAM) is resin‐based 3D printing technology, where objects are printed in seconds using volumetric light patterning. Although fast, tomographic VAM struggles to produce repeatable and accurate prints. This work demonstrates an automatic exposure method for tomographic VAM, resulting in commercial‐grade ...
