application of supramolecular polymer blending in preparation of materialswith adjustable mechanical properties is addressed. it is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. on this basis, the effect of strongly dimerising ureidopyrimidinone end groups (upy) with the capability of quadruple hydrogen bondi...
in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...
In this study, thermo-mechanical stability of two-pass constrained groove pressing (CGP) AA1050 sheets towards friction stir welding (FSW) employing hybrid powder (%50vol. micrometric graphite powder+%50vol. α-Al2O3 nanoparticles) was investigated by examining its microstructural evolutions and mechanical properties. FSW was carried out via different process variables in order to reach the high...
a considerable amount of energy is released in the form of shock wave from explosive charge detonation. shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. the rest of the shock wave energy is transferred to rock mass as ground vibration. ground vibration is conveyed to the adjacent structures by body and surface waves. geological structures li...
The Clouds and the Earth’s Radiant Energy System (CERES) project relies on geostationary (GEO) imager derived TOA broadband fluxes and cloud properties to account for the regional diurnal fluctuations between the Terra and Aqua CERES and MODIS measurements. Anchoring the GEO visible calibration to the MODIS reference calibration and stability is critical for consistent fluxes and cloud retrieva...
Polyurea-urethanes are one of the polyurethane categories that causes better phase separation due to increasing the hard segment length and non-covalent interactions. In this research, hydroxyl-terminated polybutadiene based polyurea-urethanes have been synthesized via one-pot polymerization of triethanol amine triflouroborate comlex as cross-linker, isophoron diisocyanate as curing agent and v...
bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. this microstructure has shown ultimate tensile strength of about 2.2 gpa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 hv and impact toughness in the range of 30 to 40 mpa m1/2. with ca...
We introduce a new geometric, rank-based model for the link structure of on-line social networks (OSNs). In the geo-protean (GEO-P) model for OSNs nodes are identified with points in Euclidean space, and edges are stochastically generated by a mixture of the relative distance of nodes and a ranking function. With high probability, the GEO-P model generates graphs satisfying many observed proper...
The obtainment of new materials with distinct properties by mixing two or more polymers is a potential strategy in sustainable packaging research. In the present work, blend cellulose acetate (CA) and zein (60:40 wt/wt CA:zein) was manufactured adding glycerol tributyrin as plasticizers (30% wt/wt), garlic essential oil (GEO), complexed (IC) not ?-cyclodextrin (?CD), to produce active packaging...
