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 ...

Solving an inverse Cauchy Problem for modified Helmholtz Equations depending on a polynomial expansion approximation

Academic Science Journal
In this study, a heat conduction in fin-related inverse problem for the modified Helmholtz equation is taken into consideration. The purpose of this study is to estimate the temperature on an under-specified boundary (a part of the outer border of a ...

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 ...

Sulfate‐Directed Silver Dendrites with Enhanced Stability for Ultrasensitive SERS‐Based Therapeutic Drug Monitoring

Advanced Science, EarlyView.
This study presents sulfate‐directed silver dendrites (s‐AgDs) as oxidation‐resistant SERS substrates with long‐term stability, reproducibility, and sub‐picomolar sensitivity. Sulfate ions guide anisotropic growth and protect the surface, enabling improved performance over 7 months under ambient conditions.

From Solution to Surface: How the Catalytic Environment Modulates Peptide Bond Cleavage by Metal‐Oxo Cluster Nanozymes

Advanced Science, EarlyView.
Comparison of homogeneous Hf12(sol) and heterogeneous Hf12(precip) metal‐oxo clusters enables investigation of how solubility influences nanozymatic reactivity and selectivity toward proteolysis, without introducing confounding factors from differences in cluster identity.

Quantitative Stain Mapping in X‐Ray Virtual Histology

Advanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

On relations between harmonic functions and solutions of the modified Helmholtz equation

, 2022
We consider the $m$-dimensional modified Helmholtz equation and establish two relations between its solutions in a bounded domain and harmonic functions. Both relations essentially rely on properties of the Newtonian potential. Some other characteristics of these solutions are also obtained.
