In the reaction of 4,4'-methylenebis(phenyl isocyanate), polycaprolactone diol, and N-methyldiethanolamine, they were synthesized aqueous dispersions of polyurethane cationomers, from which films were prepared after adding 0-2 wt% graphene. In order to obtain nanocomposites, graphene was previously noncovalent functionalized in tetrahydrofurane in the field of ultrasound. The chemical structure...
It is well known that high rates of fusion failure and pseudoarthrosis development (5~35%) are concomitant in spinal fusion surgery, which was ascribed to the shortage of suitable materials for bone regeneration. Citrate was recently recognized to play an indispensable role in enhancing osteconductivity and osteoinductivity, and promoting bone formation. To address the material challenges in sp...
CO2 sorption–desorption cycles with a methyldiethanolamine (MDEA)/piperazine (PZ) blend have been performed rotoevaporator. Similar to other separation technologies, the heating involved in MDEA/PZ solvent regeneration is most energy-intensive step overall process. Thus, this study investigated desorption kinetics under low-pressure (<200 mbar) and low-temperature conditions range from 308 3...
Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, absorption process frequently suffers various operational issues, including foaming. The main objective current work elucidate effect degradation product on foaming behavior in methyldiethanolamine (MDEA) piperazine (PZ) solution evaluate antifoaming performance poly...
In the last years, reduction of CO2 emissions from steel industry has been great importance. Carbon capture, oxygen blast furnaces and top gas recycling technologies, among others, have deeply studied as low carbon solutions. this paper, a novel integration capture power to technologies in steelmaking is presented. Green hydrogen via proton exchange membrane (PEM) electrolysis methyldiethanolam...
To accelerate the conversion to more sustainable lubricants, there is a need for an improved understanding of adsorption at solid/liquid interface. As first step, density functional theory computed energies can be used screen ability additives cover surface. Analogously what has been found in catalysis with universal scaling relations, we investigate here if general ranking found, independently...
