Pathological amyloidogenic prion proteins have a toxic effect on functional cells in the human cerebrum because of poor degradability and the tendency to accumulate in an uncontrolled manner under physiological conditions. HET-s, a fungal prion protein, is known to undergo conformational variations from fibrillar to nanosheet structures during a change from low to high pH conditions. It has bee...

The search for lightweight and low-cost anticorrosion coatings is particularly important in coastal environments with high salt humidity. Graphene-based are currently unable to provide long-lasting corrosion protection metals because of their “corrosion-promoting activity”, graphene-like materials, such as molybdenum disulfide (MoS2), beginning be anticipated its ability protect against metals....

Requirements of low energy consumption and material-volume reduction in the aerospace industry have spurred improvements mechanical tribological behaviors TiAl (TA) alloys. TA-graphene (TAG) has poorer properties (6.02 ± 0.42 GPa nano-hardness, 150 12.32 elasticity modulus, 802 21 MPa yield strength) than (6.25 0.52 159 14.21 850 19 TA-graphene-silver (TAGS). Multilayer graphene nanosheets were...

to explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. the electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. the graphene with the most stable configuration defect named as sw defect is considered. the hig...

Limited control over charge recombination between photogenerated charge carriers largely hinders the progress in photocatalysis. Here, we introduce metal nanoparticles (Cr, Ag) to the surface of MoS2 nanosheets by simple synthetic means creating a hybrid metal-MoS2 nanosheet system with well-defined metal/semiconductor interfaces. We demonstrate that this hybrid nanosheet structure is capable o...

   This paper explores the mechanical properties and fracture analysis of C2N-h2D single-layer sheets using classical molecular dynamics (MD) simulations. Simulations are carried out based on the Tersoff potential energy function within Nose-Hoover thermostat algorithm at the constant room temperature in a canonical ensemble. The influences of boron (B) doping on the mechanical properties, ...

This study developed a facile approach for preparing Ti(3+) self-doped TiO2-graphene photocatalyst by a one-step vacuum activation technology involved a relative lower temperature, which could be activated by the visible light owing to the synergistic effect among Ti(3+) doping, some new intersurface bonds generation and graphene oxide reduction. Compared with the traditional methods, the vacuu...
