Surface Modification of Activated Carbon Fibers with Fe3O4 for Enhancing Their Electromagnetic Wave Absorption Property

Uniform Fe3O4 coating on flower-like ZnO nanostructures by atomic layer deposition for electromagnetic wave absorption.

An elegant atomic layer deposition (ALD) method has been employed for controllable preparation of a uniform Fe3O4-coated ZnO (ZnO@Fe3O4) core-shell flower-like nanostructure. The Fe3O4 coating thickness of the ZnO@Fe3O4 nanostructure can be tuned by varying the cycle number of ALD Fe2O3. When serving as additives for microwave absorption, the ZnO@Fe3O4-paraffin composites exhibit a higher absor...

High Frequency Properties of Carbon Nanotubes and their Electromagnetic Wave Absorption Properties

Strain and Damage Sensing Property of Self-compacting Concrete Reinforced with Carbon Fibers

Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...

Land surface modification and crop diversification for enhancing productivity of a Vertisol

Vertisols occur extensively in centralIndiaand have high production potentials. Because of the high clay content (40-60% or more), high bulk density (1.5-1.8 Mg m-3) and related properties, these soils have high moisture storage capacity. Conversely, these soils become very hard when dry and very sticky when wet. Since last two decades, scientists, farmers and also the policy makers have be...

Electromagnetic Wave Surface Velocimetry

Electromagnetic wave surface velocimeters ESVs measure the Doppler shift in electromagnetic waves reflected from the water surface. They provide nonintrusive water surface velocity measurements from bridges and river banks. Comparisons with laboratory and field tests show very good agreement over a wide range of elevation and planview angles. Laboratory testing shows comparable results between ...
