The relationship between curing regime and mechanical properties of controlled low-strength material
(Elsevier Ltd, 2022)
This paper outlines research conducted on controlled low strength material (CLSM) to examine the effects of curing condition and water-cementitious material (w:cm) ratio on its engineering properties, including compressive ...
Response surfaces for compressive strength of concrete
(2013)
The aim of total quality management (TQM) is to offer satisfactorily high quality products to customers for providing increased productivity and decreased costs. Various methods are used for process improvement, development ...
Experimental and numerical investigation of heat transfer in a channel with multiple phase change materials (PCMs)
(Elsevier Ltd, 2022)
In this study, the thermal performance of an air-phase change material (PCM) unit used in free cooling applications was examined experimentally and numerically by Comsol finite element simulation software. Effects of the ...
Glutathione-responsive multifunctionalizable hydrogels via amine-epoxy "click" chemistry
(Elsevier Ltd, 2020)
A novel glutathione-responsive hydrogel was synthesized through catalyst-free epoxy-amine ‘click’ chemistry using PEG-diamine and a redox-responsive diepoxy crosslinker. The chain length of PEG-diamine component was varied ...
Monomer concentration effect on electrochemically modified carbon fiber with poly[1-(4-methoxyphenyl)-1H-pyrrole] as microcapacitor electrode
(2009)
In this study, films of poly[1-(4-methoxyphenyl)-1H-pyrrole] [poly(MPPy)] were electrochemically grown on carbon fiber microelectrodes (CFMEs) in 0.05 M of tetraethyl ammonium perchlorate-dichloromethane. The effect of ...
Electronically Tunable Memcapacitor Emulator Based on Operational Transconductance Amplifiers
(World Scientific, 2021)
Memory circuit elements are of interest due to their use in different fields of science and technology. In this research, a new multi-outputs operational transconductance amplifiers (MO-OTA)-based memcapacitor emulator is ...
Investigation of physical and mechanical properties of mortars produced by polymer coated perlite aggregate
(Elsevier Ltd, 2021)
With its low unit weight, expanded perlite (EP) offers significant advantages in heat and sound insulation in the construction sector. However, due to its high-water absorption capacity, EP affects the physical and mechanical ...
Effect of bimetallic (Ni and Co) substitution on magnetic properties of MnFe2O4 nanoparticles
(Elsevier Ltd, 2016)
Nickel and cobalt substituted manganese ferrite nanoparticles (NPs) with the chemical composition NixCoxMn1–2xFe2O4 (0.0?x?0.5) NPs were synthesized by one-pot microwave combustion route. The effect of co-substitution (Ni, ...
A new methodology for the determination of enzyme activity based on carbon nanotubes and glucose oxidase
(Elsevier, 2015)
In this research, a novel enzyme activity analysis methodology is introduced as a new perspective for this area. The activity of elastase enzyme, which is a digestive enzyme mostly of found in the digestive system of ...
Influence of raw rice husk addition on structure and properties of concrete
(2013)
When concrete is exposed to high temperatures, vapor pressure increases and the concrete may spall. In order to prevent this, polypropylene fibers are added to concrete. However, it is known that these fibers produce harmful ...
