Climate change is making droughts more frequent, which a major problem for crop yield, especially crops that are vulnerable to drought, such as common buckwheat (Fagopyrum esculentum). Drought stress affects negatively on physiological and biochemical processes of plants, leading reduced yields. This study addresses the knowledge gap regarding effective strategies mitigate drought-induced damage enhance productivity in buckwheat. We hypothesized iron oxide nanoparticles (Fe3O4 NPs) rice husk...
A model to predict the enhanced thermal conductivity of water based copper nanofluid on basis molecular dynamics simulation coupled with stochastic shows for first time that temperature a nanoparticle colliding heat source can rise rapidly within short collision period (e.g., 10-50 ps) estimated by impact due phonon transfer. Thereafter particles undergo Brownian movement in base fluid and transfer excess about 2 3 ms surrounding resulting an appreciable enhancement fluid. Microconvection...
An Al-Zn-Mg-Cu alloy is aged at 120 °C for varying time and the peak hardness (T6) found 24 h. A multi-step ageing was adapted to produce interrupted (T6I6) temper. Stress corrosion cracking behaviour of T6 T6I6 tempers has been studied by slow strain rate test free potential (FCP) applied anodic potentials in 3.5 wt.% NaCl solution. temper exhibited higher SCC resistance than FCP, but both are damaging potentials. TEM microstructures, SEM fractographs crack morphology used analyze tempers.
A fine-grain micro-alloy (MA) steel coated with nanocrystalline (NC) nickel by pulse electrodeposition (PED) has been studied electrochemical impedance spectroscopy (EIS) in a 3.5 wt. % NaCl solution and shown to have improved corrosion resistance. Hydrogen embrittlement (HE), assessed slow strain rate test (SSRT) at of 2 × 10−6 s−1, showed that the uncoated MA is highly susceptible HE, whereas NC Ni resistance HE. Fractographs revealed characteristic brittle ductile fracture features for...
It is known that conductive heat transfer takes place from the hotter to colder region of a material following Fourier's law conduction and as consequence becomes progressively heated up until it reaches temperature place. Based on thermal evolution conductivity can be estimated using equation conduction. Present work reports estimation an amorphous carbon nanotube basis associated with through molecular dynamics (MD) simulation, which very promising tool characterize thermo-physical...
A coupled molecular dynamics (MD)-stochastic simulation based model has been proposed here for the thermal conductivity of ethylene glycol (EG) copper nanofluid. The is on evolution nanoparticles dispersed in nanofluid which contact with a heat source. It natural that would move randomly by Brownian motion and repeatedly collide During each collision extract some conduction mode from source this be dissipated to base fluid during combination microconvection mode. Thus, addition normal...
A model reported by the present investigators has earlier shown that extent of heat pick up a nanoparticle during its collision with source in given nanofluid would depend on thermal conductivity (k p , unit W/m.K), density (ρ, kg/m 3 ), elastic modulus (E, GPa) and Poissons ratio (μ) source. Considering expression for period nanoparticle, factor χ =k (ρ/E) 0.4 is proposed here examined preliminary identification potential dispersoid enhancing nanofluid. The χ-factor Ag, Cu, CuO, Al 2 O SiO...
Important factors in the design of a metal feeding system for thin strip casting steel are size and shape tundish, type location flow control devices throughput.
