Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Decoupling the Impact of Deep‐Trap and Band‐Tail States on PbS Quantum Dot Photodetectors via Alkylamine Engineering

Advanced Materials Technologies, EarlyView.
Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

Boundary Element Method for the Helmholtz Equation

Journal of Mathematical Extension, 2015
The boundary element methos is applied to the Helholtltz equation. To this end we discretized the Helmholtz equation over the boundary Ω and conclude a system of equations.

Photonics of Topological Magnetic Textures

Advanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Ermakov approach for the one-dimensional Helmholtz Hamiltonian

, 1999
For the one-dimensional Helmholtz equation we write the corresponding time-dependent Helmholtz Hamiltonian in order to study it as an Ermakov problem and derive geometrical angles and phases in this contextComment: 6 pages ...

Single‐Cell Metabolic Imaging and Digital Scoring of Fat Tissue Remodeling by Label‐Free Metabolic Microscopy

Advanced Science, EarlyView.
Mid‐infrared optoacoustic microscopy (MiROM) acquires lipid‐ and protein‐ associated vibrational contrast in intact fat tissue without dyes, preserving native tissue architecture. Through lateral and axial segmentation, MiROM tracks intrinsic intracellular changes during postnatal remodeling. A quantitative spatial analysis tool (Q‐SAT) maps white‐ and

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

Advanced Science, EarlyView.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of intra‐ and inter transformation reactions of mechanochemically generated species, physical properties of polymers, environmental conditions. The direction and the magnitude of electron transfer between metal and polymer are dynamically governed by the relative ...
