Electrodeposition and characterization of polypyrrole films on T304 stainless steel
Springer Science and Business Media LLC - Tập 7 - Trang 69-72 - 2022
This work presents a study on the electrochemical deposition of polypyrrole (PPy) on T304 stainless steel and the effects that glow discharge plasma (GDP) in aqueous solution had when doping with polypyrrole (PPy). Deposition and doping were carried out at atmospheric pressure with times of 10, 30, and 60 min. The results showed that GDP doping changed the morphology and increased the presence of ......
Zeolite Modified Vanadium Pentoxide Sensors for the Selective Detection of Volatile Organic Compounds
Springer Science and Business Media LLC - Tập 1 - Trang 3349-3354 - 2016
Exposure to volatile organic compounds can lead to asphyxiation, pneumonia like conditions, comas, seizures and irreversible lung, kidney and central nervous system damage. Volatile organics are additionally extremely flammable and explosive, making their early detection in the immediate environment increasingly important. Metal oxide semiconductor (MOS) gas sensors present a potential technology ......
Performance of HfOx- and TaOx-based Resistive Switching Structures for Realization of Minimum and Maximum Functions
Springer Science and Business Media LLC - Tập 3 - Trang 3427-3432 - 2018
In our contribution we present and analyze implementation of the resistive switching structures for logic application based on Zadeh fuzzy logic. Resistive switching structures based on HfOx and TaOx were connected in an anti-serial configuration (complementary resistive switch). The complementary resistive switches integrated into logic circuit for Min-Max function implementation were analyzed us......
Nghiên cứu cấu trúc vi mô trong hợp kim AA7075 khi hàn bằng các kim loại bổ sung khác nhau Dịch bởi AI
Springer Science and Business Media LLC - Tập 4 - Trang 3017-3029 - 2019
Mặc dù AA 7075 là một hợp kim nhôm có tính chất cơ kỹ thuật cao, nhưng nó không thường được áp dụng trong sản xuất. Điều này xảy ra vì nó được coi là rất khó để sản xuất các mối hàn không có khuyết tật. Nguyên nhân là hợp kim này có xu hướng bị nứt nóng. Các vấn đề kim loại học xuất hiện trong quá trình hàn AA 7075 vẫn chưa được giải quyết hoàn toàn nhưng đã được giảm thiểu bằng cách sử dụng các h......

Rheological effect of the concentration of nanoparticles in cassava starch
Springer Science and Business Media LLC - Tập 4 - Trang 2889-2896 - 2019
Biodegradable material was prepared from cassava starch in combination with zinc oxide nanoparticles (ZnO NPs) to give the properties of microbial growth resistance, glycerin concentrations were varied to 5%, 10%, and 20% (w/v) for the study of the rheological properties. The nanoparticles were characterized by a spectrophotometer where an exciton peak at 370 nm was obtained. The different samples......
The Influence of Metalized Graphene Oxide/Reduced Graphene Oxide and Sulfonated Polystyrene on Dental Pulp Stem Cell Differentiation and Protein Adsorption
Springer Science and Business Media LLC - Tập 2 - Trang 1059-1070 - 2017
Human dental pulp stem cells (DPSCs) can differentiate, showing potential for regenerative medicine. Designing artificial surfaces with properties appropriate for the initiation of extracellular matrix (ECM) adsorption and organization is a critical step in tissue engineering and can greatly impact protein adhesion. Sulfonated polystyrene (SPS), used as a scaffold for tissue development, stimulate......
Porosity and surface defects characterization of hot isostatically pressed Inconel 718 alloy turbine blades printed by 3D laser metal fusion technology
Springer Science and Business Media LLC - Tập 7 - Trang 197-201 - 2022
Selective laser melting (SLM) additive manufacturing technique was applied to fabricate the turbine blade test parts using Inconel (IN) 718 powder. To reduce the porosity, the SLM-built turbine blade parts were subjected to the hot isostatic pressing (HIP) post-treatment. The focus of this study is to study the porosity, surface defects and texture of the SLM-printed and HIP-treated complexly shap......
CO Sensor based on Thin Film of ZnO Nanoparticles
Springer Science and Business Media LLC - Tập 2 - Trang 2695-2700 - 2017
In this research, zinc chloride has been used as precursor and zinc oxide nanostructures have been synthesized by Sol-Gel process, using deionized water and 2-propanol as solvents in order to evaluate their influence on the final materials and their properties. Thin films of synthesized samples were deposited on glass substrates by the dipping method. The structure and morphology of crystals were ......
Polystyrene adsorbed multi-walled carbon nanotubes incorporated polymethylmethacrylate composites with modified percolation phenomena
Springer Science and Business Media LLC - - 2017
Extensive work has been done on the modification of multi-walled carbon nanotubes (MWCNTs) to improve their characteristics. Here, polystyrene (PS) was adsorbed on the surface of MWCNTs by dispersion process, using toluene as medium. PS modified MWCNTs (PS-MWCNTs) have been dispersed in polymethylmethacrylate (PMMA) matrix to prepare composite, PS-MWCNTs/PMMA. It is expected that PS adsorbed at th......
