Relativistic and correlation effects in atoms

, 2005
This review article deals with some case studies of relativistic and correlation effects in atomic systems. After a brief introduction to relativistic many-electron theory, a number of applications ranging from correlation energy to parity non ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Investigation of the effects of luster glazes on chamotte bodies

European Mechanical Science
Luster is a thin film layer that forms on the glaze surface when metal ions migrate toward the surface in a reducing atmosphere. This film refracts light and disperses it into spectral colors, producing metallic and rainbow-like effects.

Unstable attractors induce perpetual synchronization and desynchronization

, 2002
Common experience suggests that attracting invariant sets in nonlinear dynamical systems are generally stable. Contrary to this intuition, we present a dynamical system, a network of pulse-coupled oscillators, in which \textit{unstable attractors} arise ...

Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials

Advanced Functional Materials, EarlyView.
Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

An Introduction to Typology of Human Motifs of Luster-painted earthenware in Middle Islamic Centuries of Rei and Kashan [PDF]

هنر اسلامی, 2016
Studying the ornamental motifs of luster-painted earthenware in the middle Islamic centuries of Iran provides us with diverse information. Although the pottery are of less visual attractiveness than enamel ones, they are regarded as a reliable resource ...

Comparative studies of the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of ^{25}Mg^{+}

, 2003
We have employed the relativistic coupled cluster theory to calculate the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of singly ionized magnesium.

A Non‐Reciprocal Architected Porous Medium

Advanced Functional Materials, EarlyView.
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Galaxy Collisions, Gas Stripping and Star Formation in the Evolution of Galaxies

, 2004
A review of gravitational and hydrodynamical processes during formation of clusters and evolution of galaxies is given. Early, at the advent of N-body computer simulations, the importance of tidal fields in galaxy encounters has been recognized.
