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 ...
The effect of TiO2 contained within a titanium silicalite (TS-1) catalyst and on the selective oxidation of ammonia
(Berkeley Electronic Press, 2013)
The selective oxidation of ammonia to hydroxylamine using titaniumsilicalite-1 as a catalyst with an increasing content range of 1-2.5 wt% TiO2 was systematically investigated in a batch reactor. The hydroxylamine yielded ...
Destructive fibrosarcoma of the maxillary sinus
(2018)
Paranasal fibrosarcoma of nasal cavity and paranasal sinuses is a very rare malignant tumor. It is usually presented with nasal obstruction and epistaxis. In this clinical report, clinical symptoms, pathogenesis, and ...
Mössbauer studies and magnetic properties of cubic CuFe2O4 nanoparticles
(Springer New York LLC, 2019)
This study reports the preparation and characterization of nanocrystalline spinel powder of cubic copper ferrite nanoparticles (NPs) which have been fabricated via a cost-effective citrate sol–gel approach. The structural ...
Comparisons of dry grinding kinetics of lignite, bituminous coal, and petroleum coke
(Taylor and Francis, 2013)
The objective of this study was to analyze dry grinding kinetics of three different solid fuels in terms of selection and breakage distribution functions values using a batch laboratory ball mill. For this purpose, first, ...
The use of co-polymer flocculants for the elimination of the environmental effects of wastewater of a coal washer and design of a thickener for supplies of fresh water
(Taylor and Francis, 2013)
A washing plant belonging to Özberil Mining Co. (Denizli/Turkey) has a 50 t/h of capacity and coal was washed with heavy media separation to increase its quality. Wastewaters of coal tailing streams of the washing plant ...
Prediction of the bond grindability index from the sink-float test data of coals
(Taylor and Francis, 2013)
In this study, a relation for calculating the Bond grindability by the sink-float test data of coals was studied. Primarily, sink-float tests for three coal samples were made. Secondly, the cumulative weight and ash content ...
Interrelationships between the bond grindability with physicomechanical and chemical properties of coals
(Taylor and Francis, 2013)
In this research, different techniques for the estimation of Bond grindability (Gbg) values of coals are studied. Data from ten sub-bituminous coals from Turkey are used by featuring physicomechanical (ISI, Is, and FD) and ...
