Relationship between Polymer Dielectric Constant and Percolation Threshold in Conductive Poly(styrene)‐Type Polymer and Carbon Black Composites

Journal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015
We study the effect of dielectric constant of some poly(styrene)‐type polymer matrix on the percolation threshold in conductive polymer composites with carbon black (CB). We demonstrate that percolation threshold diminishes with an increment of the dielectric constant of polymer matrix. We chose polystyrene and other three polymers similar in structure

Vibrational Order, Structural Properties, and Optical Gap of ZnO Nanostructures Sintered through Thermal Decomposition

Journal of Nanomaterials, Volume 2014, Issue 1, 2014., 2014
The sintering of different ZnO nanostructures by the thermal decomposition of zinc acetate is reported. Morphological changes from nanorods to nanoparticles are exhibited with the increase of the decomposition temperature from 300 to 500°C. The material showed a loss in the crystalline order with the increase in the temperature, which is correlated to ...

Contrasting effects of vertebrate and invertebrate herbivores on leaf litter decomposition in terrestrial ecosystems: A meta‐analysis

Functional Ecology, Volume 39, Issue 12, Page 3372-3384, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivores influence litter quality, soil properties and decomposer communities, with cascading effects on litter decomposition. Vertebrate and invertebrate herbivores can affect decomposition through the same two pathways (litter quality‐ and soil‐mediated) but are ...

Cellulose‐Based Polymer Composite with Carbon Black for Tetrahydrofuran Sensing

International Journal of Polymer Science, Volume 2013, Issue 1, 2013., 2013
This work focused on studying the sensing efficiency of tetrahydrofuran (THF) by composite films made of thin layers of a cellulose‐based polymer and carbon black. We analyze the reproducibility, durability, desorption time, and the sensitivity percent as a function of the amount of solvent.
