Study on the preparation process and performance of a conductive, flexible, and transparent wood

open access: yesJournal of Materials Research and Technology, 2021
As one of the most sustainable resources, wood has been widely used in the fields of construction, decoration, flooring and furniture. The emergence of transparent wood further expands the application fields of wood to solar cells, luminescent magnetic ...

Magnetic properties of wood ash

open access: yes, 2023
Magnetic enhancement of soils attracts for decades attention in environmental magnetism. Mechanisms of this enhancement have been discussed since sixties of the last century, when this effect was recognized mainly in archeological surveying. At present, the attention is paid mostly to topsoil magnetic enhancement.

Influence of production variables and starting material on charcoal stable isotopic and molecular characteristics [PDF]

open access: yes, 2008
We present a systematic study on the effect of starting species, gas composition, temperature, particle size and duration of heating upon the molecular and stable isotope composition of high density (mangrove) and low density (pine) wood.

The effects of stellar winds on the magnetospheres and potential habitability of exoplanets [PDF]

open access: yes, 2014
Context: The principle definition of habitability for exoplanets is whether they can sustain liquid water on their surfaces, i.e. that they orbit within the habitable zone.

Study on Moisture Absorption and Water Absorption of PMMA Wood-plastic Composites Based on TD-NMR

open access: yesChinese Journal of Magnetic Resonance, 2023
In this study, time-domain nuclear magnetic resonance (TD-NMR) technology was employed to explore the moisture state and spin-spin relaxation (T2) characteristics of polymethyl methacrylate (PMMA) wood-plastic composites during the moisture absorption ...

Precession of Isolated Neutron Stars II: Magnetic Fields and Type II Superconductivity [PDF]

open access: yes, 2002
We consider the physics of free precession of a rotating neutron star with an oblique magnetic field. We show that if the magnetic stresses are large enough, then there is no possibility of steady rotation, and precession is inevitable.

In-situ anchoring of Fe3O4/ZIF-67 dodecahedrons in highly compressible wood aerogel with excellent microwave absorption properties

open access: yesMaterials & Design, 2019
Lightweight aerogels with superior cavities have attracted great interest in the field of electromagnetic wave absorbing materials. In this work, a hierarchical porous wood aerogel modified with Fe3O4/ZIF-67 (Fe3O4/ZIF-67@WA) with high compressibility ...

Precise nondestructive location of defective woody tissue in grapevines affected by wood diseases

open access: yesPhytopathologia Mediterranea, 2020
Grapevine trunk diseases are major threats to viticulture. A diverse array of Ascomycetes and Basidiomycetes can affect perennial and, indirectly, annual organs of grapevines.
