Irreversibility analysis of a two-evaporator vapour compression refrigeration system
(Inderscience Enterprises Ltd., 2015)
In this study, irreversibility analysis of a two-evaporator vapour compression refrigeration system under the influence of superheating and subcooling effects was carried out. The thermodynamic properties of the refrigerants ...
Investigation of the component exergy efficiencies of a two stage vapour compression cycle
(Inderscience Enterprises Ltd., 2018)
The exergy efficiencies of the components (compressor I and II, condenser, evaporator and flash tank) of a two stage vapour compression refrigeration cycle were analysed with respect to evaporator and condenser temperatures ...
Irreversibility analysis of a compression refrigeration cycle using natural refrigerants for a sustainable future
(2012)
Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of ...
Ion imprinted cryogels for selective removal of Ni(II) ions from aqueous solutions
(Elsevier B.V., 2017)
In this article, ion imprinted poly(hydroxyethyl methacrylate) (PHEMA) based supermacroporous cryogels were synthesized in the presence of a functional monomer, namely N-methacryloyl-histidine methyl ester (MAH), to be ...
One step effective removal of Congo Red in chitosan nanoparticles by encapsulation
(Elsevier B.V., 2017)
Chitosan nanoparticles (CNPs) were prepared with ionotropic gelation between chitosan and tripolyphosphate for the removal of Congo Red. The production of chitosan nanoparticles and the dye removal process was carried out ...
Investigation of the breakage parameters of gypsum as dependent on interstitial filling in a laboratory ball mill
(Springer Nature, 2011)
Gypsum is an industrial material used in many applications such as building and chemical industry, fertilizer manufacture, medicine and dentistry. In these industries, there is need for finely ground gypsum. Energy consumption ...
Investigation of breakage behavior of different mineralogical and morphological characteristic pumices
(2011)
The objective of this study is to analyze dry grinding behavior of four different pumices in terms of Bond grindability value, selection and breakage parameters values. For this purpose, firstly, Bond grindability test ...
A numerical study on the effects of EGR and spark timing to combustion characteristics and NOx emission of a GDI engine
(Taylor and Francis Inc., 2016)
EGR is one of the most significant strategies for reducing especially nitrogen oxides (NOx) emissions from internal combustion engines. The thermal efficiency of spark ignition engines is lower than compression ignition ...
Toward a universal method for preparing molecularly imprinted polymer nanoparticles with antibody-like affinity for proteins
(American Chemical Society, 2016)
We describe a potentially universal, simple and cheap method to prepare water-compatible molecularly imprinted polymer nanoparticles (MIP-NPs) as synthetic antibodies against proteins. The strategy is based on a solid phase ...
Decomposition of NaBH4 with self-regeneration of carbon-supported CoCl2 catalyst
(Taylor and Francis Inc., 2017)
In this study, economically favorable CoCl2 catalysts at four different amounts were supported on activated carbon (AC) for NaBH4 dehydrogenation. Supported catalyst could achieve hydrogen release for 2,060 cycles, which ...
