Performance of leonardite humic acid as a novel superplasticizer in Portland cement systems
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
Significance of superplasticizers (SPs) in sustainable development of concrete industry is well known regarding to reduced water and Portland cement content of the mixtures. Development of eco-efficient alternative types ...
Quantum dot and electron acceptor nano-heterojunction for photo-induced capacitive charge-transfer
(NATURE RESEARCHHEIDELBERGER PLATZ 3, BERLIN 14197, GERMANY, 2021)
Capacitive charge transfer at the electrode/electrolyte interface is a biocompatible mechanism for the stimulation of neurons. Although quantum dots showed their potential for photostimulation device architectures, dominant ...
Amorphous boron phosphide: An ab initio investigation
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
We generate a structural model of amorphous boron phosphide (BP) by quenching the melt via ab initio molecular dynamics calculations and compare it structurally and electrically with the crystal. We find that both phases ...
Optical detection of microplastics in water
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2021)
Unfortunately, the plastic pollution increases at an exponential rate and drastically endangers the marine ecosystem. According to World Health Organization (WHO), microplastics in drinking water have become a concern and ...
Investigation of the Effects of Multi-Layer Winding Structures in Two Pole Synchronous Reluctance Machines
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, a comparative study is performed between single, various double, and triple-layer winding structures to investigate the effects of the winding MMF harmonics and end winding length on the two-pole synchronous ...
Sensorless Position and Speed Control of IPMSM with Sliding Mode Observer and Voltage Signal Injection
(Institute of Electrical and Electronics Engineers Inc., 2021)
A sensorless control approach based on a sliding mode observer for predicting the rotor position and speed is studied in this work. For predicting the motor speed and position, the sliding mode observer followed by a phase ...
Experimental and Molecular Dynamics Simulation-Based Investigations on Hydrogen Embrittlement Behavior of Chromium Electroplated 4340 Steel
(ASMETWO PARK AVE, NEW YORK, NY 10016-5990, 2021)
In this study, chromium electroplating process, corresponding hydrogen embrittlement, and the effects of baking on hydrogen diffusion are investigated. Three types of materials in the form of Raw 4340 steel, Chromium ...
Development of an optical measurement system for surface depth measurements and study of focus effect on determination of steel inclusion content by EN-10247
(SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS1000 20TH ST, PO BOX 10, BELLINGHAM, WA 98225, 2021)
Surface inspections are important in steelmaking processes to characterize the final product's quality. We present a method to measure surface depth profile using laser scattering geometry. This technique is used to analyze ...
