A Compressor model to determine cooling cycle efficiencies and performances without or with internal heat exchanger for specific refrigerant
(2023)
Today, the importance of refrigeration has
increased due to the shortage of food, food storage,
health, and industrial cooling. Global warming is the
most important environmental problem that the
world has faced recently. ...
Morphological, microstructural and photocatalytic characterization of undoped and Ni, Co doped Fe2O3 particles synthesized by sonochemical method
(Scientific & Technical Research Council Turkey-TUBITAK, 2022)
In this study, an abundant and eco-friendly photocatalytic material, Fe2O3 particles were synthesized by sonochemical method. Morphological and microstructural investigations of synthesized undoped and Ni, Co-doped Fe2O3 ...
Preparation and characterization of porous hydroxyapatite pellets: effects of calcination and sintering on the porous structure and mechanical properties
(Sage Publications Ltd, 2016)
In this study, porous hydroxyapatite structures were produced by using urea particles of 600-850 mu m size. Samples with two different urea composition (25 and 50 wt%) were prepared along with samples without any urea ...
Comparison of deep drawability of AA5754-H22 and AA6061-T6 aluminum alloys for automotive applications
(Carl Hanser Verlag, 2017)
Being one of the most commonly applied sheet metal forming processes in automotive industry, deep drawing technologies are challenged by the concerns of global warming for higher fuel economy requirements in the recent ...
Effects of alumina (Al2O3) addition on the cell structure and mechanical properties of 6061 foams
(Cambridge Univ Press, 2013)
In this study, a powder blend representing 6061 Al-alloy was first mixed with Al2O3 ceramic particles and then foamed by using the powder compact melting method. 6061-Al2O3 foams and control specimens 6061 foams (without ...
Effect of coating method on the surface characteristics of niti shape memory alloy
(Trans Tech Publications Ltd, 2020)
Metallic materials including stainless steel, cobalt-chromium alloys, titanium and its alloys, and nickel-titanium (NiTi) shape memory alloys have been used in biomedical applications since the 1940s due to their favorable ...
Cooling performance prediction of a metal foam internal heat exchanger: An artificial neural network approach
(2023)
Although HFC refrigerants have high global warming potential (GWP) values, they are preferred due to their satisfactory cooling performance and A1 fire protection classification. If possible, alternatives of HFC-type ...
Strain hardening reduces energy absorption efficiency of austenitic stainless steel foams while porosity does not
(Elsevier Sci Ltd, 2018)
Strain hardening significantly affects the mechanical function of steel foams. We compare hardening and failure of two commercially available austenitic stainless steel foams (316L and 310) spanning strut porosities of 9.4 ...
Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Heidelberg, 2020)
Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ...
Core-shell PVA/gelatin nanofibrous scaffolds using co-solvent, aqueous electrospinning: toward a green approach
(Wiley, 2018)
Electrospinning (ES) of gelatin often requires cytotoxic organic solvents or acidic environments, which deteriorate cell recognition sites. In this study, aqueous, non-toxic, co-solvent ES was performed to obtain core-shell ...
