Foams of gray cast iron as efficient energy absorption structures: a feasibility study
(Wiley-V C H Verlag Gmbh, 2019)
Gray cast iron foams, were produced using a reticulated polyurethane by using a modified investment casting process. To evaluate the attributes of the produced micro-geometries, foam segments and single struts are investigated ...
Effect of the improved bulk modulus on dielectric properties of poly (methyl methacrylate)/borax hybrid composite at radar frequencies
(Materials Today Communications, 2022)
A cross-linkable thermoplastic has been synthesized by the Atom Transfer Radical Polymerization method for the
development of PMMA/Borax composite with broadband radio-absorbing properties. The radio-physical characteristics ...
FKBPs in bacterial infections
(Elsevier Science Bv, 2015)
Background: FK506-binding proteins (FKBPs) contain a domain with peptidyl-prolyl-cis/trans-isomerase (PPlase) activity and bind the immunosuppressive drugs FK506 and rapamycin. FKBPs belong to the immunophilin family and ...
Calibration-free extraction of constitutive parameters of magnetically coupled anisotropic metamaterials using waveguide measurements
(Amer Inst Physics, 2017)
A calibration-free method for extraction of electromagnetic properties of magnetically coupled anisotropic biaxial metamaterial (MM) slabs from waveguide measurements is proposed. It relies on three measurement steps (thru, ...
Effect of soft segment molecular weight on tensile properties of poly(propylene oxide) based polyurethaneureas
(Elsevier, 2012)
Influence of soft segment molecular weight and hard segment content on the morphology, thermomechanical and tensile properties of homologous polyurethaneurea copolymers based on narrow molecular weight poly(propylene ...
Production of rare earth element oxide powders by solution combustion: a new approach for recycling of NdFeB magnets
(Royal Society of Chemistry, 2022)
NdFeB magnets are employed in various technological applications due to their outstanding magnetic properties, such as high maximum energy product, high remanence and high coercivity. Production of NdFeB has gathered more ...
An Ab Initio and DFT study of structure and conformers of glycerol
(American Institute of Physics, 2020)
In this paper, the effect of the simultaneous rotation of two different groups, hydroxyl (OH) and hydroxymethyl (CH2OH) groups, on the basic properties of Glycerol are comprehensively studied. Relative energies are reported ...
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 ...
A sufficient condition for the almost global stability of nonlinear switched systems with average dwell time
(Ieee, 2019)
A sufficient condition for the almost global stability of nonlinear switched systems under average dwell time restriction is obtained. This condition is derived leaning upon the existence of multiple Lyapunov densities, ...
Performance evaluation of reverse logistics in food supply chains in a circular economy using system dynamics
(Wiley, 2020)
Supply chains are composed of multiple stakeholders who have complex interrelationships. In addition, the forward and reverse flow of materials, information, human resources, and finance occurs among different stakeholders ...
