Dynamic transition of nanosilicon from indirect to direct-like nature by strain-induced structural relaxation
(AIP Advances, 2021)
Silicon nanoclusters exhibit light emission with direct-like ns-mu s time dynamics; however, they show variable synthesis and structure, optical, and electronic characteristics. The widely adopted model is a core-shell in ...
Prediction of shrinkage ratio of ZA-27 die casting alloy using artificial neural network, computer aided simulation, and comparison with experimental studies
(Sharif University of Technology, 2021)
In cast alloys with a long freezing range such as ZA-27, casting defects like porosity and shrinkage may occur in case of failure to control casting variables. In this study, the role of casting variables in the formation ...
Polarization-based surface enhanced Raman scattering from single colloidal DNA decorated with 3 nm silicon nanoparticles
(American Institute of Physics Inc., 2021)
Surface enhanced Raman scattering (SERS), in which sample molecules are placed in the proximity of conducting nanostructures, subjects the molecules to intense electron oscillation (plasmon) field. The intense field, ...
Time-thermo-dynamics of anti-Stokes and Stokes scattering and luminescence in 1-nm silicon nanoparticles: Toward an optical nanorefrigerator
(American Institute of Physics Inc., 2022)
The thermodynamics of nanosystems is interesting, as they constitute the transition between the atomistic and solid states. This is empowered by the development of tools to manipulate individual atoms and perform atomistic ...
Electrochemical α-fetoprotein immunosensor based on Fe3O4NPs@covalent organic framework decorated gold nanoparticles and magnetic nanoparticles including SiO2@TiO2
(Springer, 2022)
The early diagnosis of major diseases such as cancer is typically a major issue for humanity. Human alpha-fetoprotein (AFP) as a sialylated glycoprotein is of approximately 68 kD molecular weight and is considered to be a ...
A novel paraoxon imprinted electrochemical sensor based on MoS(2)NPs@MWCNTs and its application to tap water samples
(Elsevier, 2022)
Organophosphorus pesticides are widely utilized in agricultural fertility. However, their long-term accumulations result in serious damage to human health and ecological balance. Paraoxon (PAR) can block acetylcholinesterase ...
A Study On The Examination of the Sinter Metallographic Structure
(European Journal of Technique, 2020)
Sintering process is carried out domestic and imported iron ore powders, fluxes, coke dust, metallurgical recycling powders and slag forming agents. Nowadays, in order to obtain process and operating parameters that will ...
Emerging Methods of Monitoring Volatile Organic Compounds for Detection of Plant Pests and Disease
(MDPI, 2022)
Each year, unwanted plant pests and diseases, such as Hendel or potato soft rot, cause damage to crops and ecosystems all over the world. To continue to feed the growing population and protect the global ecosystems, the ...
Development of novel inhibitive water-based drilling muds for oil and gas field applications
(Elsevier, 2022)
The aim of this study is to develop inhibitive drilling fluid systems generated from waste materials that can contribute to the reduction of potential well instability problems caused by drilling fluid based on rheological ...
Industrial scale extrusion performance of cryogenically processed DIN 100 Cr6 and DIN 21NiCrMo2 steels
(CSIC Consejo Superior de Investigaciones Cientificas, 2022)
The effects of diferent heat and cryogenic (sub-zero) treatment parameters such as temperature and holding time on the microstructure (amount of retained austenite) and hardness of extrusion molds produced from the 21NiCrMo2 ...
