The ability to synthesize multicomponent nanocomposites (NCs) is important for exploring their functional properties of not only individual single components but also combinations in technological applications. This paper presents an investigation on the synthesis and characterization water-soluble bifunctional ZnO−Au NCs, which ZnO provides fluorescence Au used organic functionality bioconjugation. nanocrystals were employed as seeding material nucleation growth reduced gold by citrate form...
High-quality ordinary differential equation (ODE) solver libraries have a long history, going back to the 1970s. Over past several years we implemented, on top of PETSc linear and nonlinear package, new general-purpose, extensive, extensible library for solving ODEs algebraic equations (DAEs). Package includes support both forward adjoint sensitivities that can be easily utilized by TAO optimization which is also part PETSc. The ODE/DAE integrator strives highly scalable but deliver high...
To improve the mechanical properties of high-entropy alloys (HEAs) and expand application range metastable engineering, NbZrTiTa alloy was researched. The results show that this exhibits uniform element distribution a single-phase body-centered cubic (BCC) structure. During loading, diffusion occurs, then TiZr-rich TaNb-rich regions form. increased Ti Zr content reduces stability BCC structure leads to in-situ transformation in region. Element ductility by absorbing loading work releasing...
An ant colony optimization (ACO)-based methodology for solving a multimode resource-constrained project scheduling problem (MRCPSP) with the objective of minimizing duration is presented. With regards to need determine sequence and mode selection activities MRCPSP, two levels pheromones each are proposed guide search course in ACO algorithm. The corresponding heuristics probabilities type pheromone considered, their calculation algorithms flowchart algorithm described, where serial schedule...
This work develops new implicit-explicit time integrators based on two-step Runge--Kutta methods. The class of schemes interest is characterized by linear invariant preservation and high stage orders. Theoretical consistency, stability, stiff convergence analyses are performed to reveal the excellent properties these framework offers extreme flexibility in construction partitioned since no coupling conditions necessary. Practical orders three, four, six constructed used solve several test...
We investigate a new class of implicit–explicit singly diagonally implicit Runge–Kutta methods for ordinary differential equations with both non-stiff and stiff components. The approach is based on extrapolation the stage values at current step by in previous step. This was first proposed authors context general linear methods.
In the numerical solution of partial differential equations using a method-of-lines approach, availability high order spatial discretization schemes motivates development sophisticated time integration methods. For multiphysics problems with both stiff and nonstiff terms implicit-explicit (IMEX) stepping methods attempt to combine lower cost advantage explicit favorable stability properties implicit schemes. Existing IMEX Runge--Kutta or linear multistep methods, however, suffer from...
Saturation overshoot and pressure are studied by incorporating dynamic capillary pressure, hysteresis hysteretic coefficient with a traditional fractional flow equation in one-dimensional space. Using the method of lines, discretizations constructed applying Castillo–Grone's mimetic operators space direction semi-implicit integrator time direction. Convergence tests conservation properties schemes presented. Computed profiles capture both saturation phenomena. Comparisons between numerical...
