Abstract 2D materials possess a range of unique and exclusive properties due to their ultrathin feature, leading forefront role in several research areas, including electronics, photonics, catalysis renewable energy. To ensure wider application for high‐quality materials, there is global pursuit find new “industrial scale” methodologies the facile fabrication advanced materials. Blowing method ...

We investigate spatial cross-correlations between two constituents, both belonging to the same microstructure. These investigations are based on two approaches: one via the measurement of the cross-correlation function and the other uses the spatial distances between the constituents. The cross-correlation function can be measured using the fast Fourier transform, whereas the distances are dete...
identification and recognition of incomplete embryo is a new matter which has been raised recently. but rapid development of technology and recognition of prenatal disorders made abortion a means to relive and to prevent a child with untreatable and dangerous diseases from having a hard life. but some people are involved in it and it has created many social disorders. although many religious ju...
this research was conducted to study the effect of lime based flux with the composition of cao-20%caf2-8%feo on simultaneous removal of phosphorus and sulfur from hot metal. the effects of na2o and oxygen blowing were also studied. the experiments were performed using an induction furnace and hot metal produced in isfahan steel company in the temperature range 1350-1450 ºc. the results showed t...
Polyurethane foams currently dominate the global foam market. Nevertheless, main drawback of these remains use toxic isocyanate reagents. To overcome this issue, several ways have been explored. The most promising route appears to be aminolysis 5-membered cyclic carbonates leading formation polyhydroxyurethanes (PHUs). However, lack reactivity systems using C5-cyclic limits application range PH...
