Solar-cycle variability of composite geometry in solar wind turbulence

open access: yesAstronomy & Astrophysics
Context. The composite geometry and spectral anisotropy of solar wind turbulence are very important topics in the investigations of solar wind. Aims. In this work, we use magnetic field and plasma data from the Wind spacecraft, measured from January 1995

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

open access: yesAdvanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman [PDF]

open access: yes, 2005
Knowledge of the spatial characteristics of stress and fractures in reservoirs is important for optimising production and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better ...

Nanoconfinement‐Induced Second‐Harmonic Circular Dichroism via Chirality–Ferroelectric Coupling

open access: yesAdvanced Functional Materials, EarlyView.
Nanoconfinement of a ferroelectric nematic liquid crystal within a chiral nanoporous sponge yields an enhanced second‐harmonic generation circular dichroism (|gSHG–CD| ≈ 1.1). Polarization‐resolved analysis suggests an additional magnetic‐dipole‐associated nonlinear contribution under nanoconfinement, highlighting chirality–ferroelectric coupling as a ...

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

open access: yesAdvanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

Influence of the electronic states anisotropy on the band gap pressure coefficient of InxGa1-xN alloys

open access: yes, 2009
Using the first-principle methods, we investigate the structural and electronic properties of the wurtzite InxGa1-xN (0 < x < 1) alloys under hydrostatic pressure.

Study of thermal conductivity anisotropy in deformed copper plates

open access: yesТехнологія та конструювання в електронній апаратурі, 2004
The study shows that copper plates subjected to significant thickness deformations exhibit anisotropy in thermal properties. Based on experimental data on electrical conductivity anisotropy, a fractal model of the structure of deformed metal, and the ...

Influence of rock heterogeneity on the correlation between uniaxial compressive strength and Brazilian tensile strength

open access: yesScientific Reports
To offer guidance for using Brazilian tensile strength (BTS) to estimate UCS of heterogeneous rocks, this study uses sandstone (fine or coarse grain) and gneiss (0°, 45°, 90° inclined anisotropy) to investigate the influence of grain size or anisotropy ...
