Experimental characterization of contact resistance of desert soil with waste-enhancement materials in grounding systems

Results in Engineering
This study aims to investigate how the electrical-resistivity of different soils and grounding enhancement-materials is influenced by water-content and the dehydration under ambient and high-constant temperatures.

Composite Materials with Enhanced Conductivities [PDF]

Advanced Engineering Materials, 2016
The authors have analyzed the isotropic thermal/electrical conductivities of two types of specially structured composite materials. Closed‐form results have been obtained for predicting the conductivities of the composites, and the accuracy has been verified by FE simulations.

Toughening materials: enhancing resistance to fracture [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
It has been said that ‘God invented plasticity, but the Devil invented fracture!’ Both mechanisms represent the two prime modes of structural failure, respectively, plastic collapse and the rupture/breaking of a component, but the concept of developing materials with enhanced resistance to fracture can be difficult.

SMRT and Illumina RNA sequencing reveal novel insights into the heat stress response and crosstalk with leaf senescence in tall fescue

BMC Plant Biology, 2020
Background As a cool-season grass species, tall fescue (Festuca arundinacea) is challenged by increasing temperatures. Heat acclimation or activation of leaf senescence, are two main strategies when tall fescue is exposed to heat stress (HS).

Novel materials to enhance keratoprosthesis integration [PDF]

British Journal of Ophthalmology, 2000
The successful integration of keratoprostheses (KPros) within the cornea depends in part on peripheral host keratocyte adhesion to anchor the implant in place and prevent epithelial downgrowth. The following study incorporated different acrylate co-monomers with poly(hydroxyethyl methacrylate) (p(HEMA)) and measured the suitability of these materials ...

Strategies for Enhancing the Dielectric Constant of Organic Materials

The Journal of Physical Chemistry C, 2022
High dielectric constant organic semiconductors, often obtained by the use of ethylene glycol (EG) side chains, have gained attention in recent years in the efforts of improving the device performance for various applications. Dielectric constant enhancements due to EGs have been demonstrated extensively, but various effects, such as the choice of the ...

Understanding and enhancing polarization in complex materials [PDF]

Computing in Science & Engineering, 2004
Recent advances in theoretical methods and high-performance computing allow for reliable first-principles investigations of complex materials. This article focuses on calculating and predicting the properties of piezoelectrics and "designing" new materials with enhanced piezoelectric responses. This paper considers two systems: boron-nitride nanotubes (
