| 1 | Synthesis and Characterization of Hydrogels Based on Potato Starch/Poly(vinyl Alcohol)/N,N′-Methylenebisacrylamide显示文摘Several hydrogels were synthesized by free-radical polymerization in an aqueous medium based on potato starch(PS),poly(vinyl alcohol)(PVA),and N,N′-Methylenebisacrylamide(MBAm),being possible to study these hydrogels as a function of the proportion of components incorporated.In this way,the products generated from the synthesis were characterized by swelling and deswelling kinetics,the first swelling being verified with Schott and statistical models,allowing to contrast the proximity between the experimental and theoretical behavior.Additionally,water retention in soil(R%),spectroscopy(FTIR),morphological(SEM),and thermal(TGA and DSC)analysis allowing to know the intrinsic characteristics of the material,increasing in general terms the knowledge of this type of material.In this context,it was possible to verify the characteristics and effectiveness of the synthesis and crosslinking of the main components.The experimental results obtained show that the synthesized hydrogels present representative swellings consistent with kinetic and statistical models,optimal thermal stability depending on the amount of crosslinker,and excellent water retention in environments such as soil,presenting it as an excellent alternative to be used in agro-industrial applications in an eco-friendly way. | Diego David Pinzón-Moreno Eder Clidio Vicuña-Galindo JoséVulfrano González-Fernández JoséLuis Soto-Gonzales María Verónica Carranza-Oropeza | 2022 | Journal of Renewable Materials2022，10，8： | 0 |
| 2 | Multi-Material ALE with AMR for Modeling Hot Plasmas and Cold Fragmenting Materials显示文摘We have developed a new 3D multi-physics multi-material code,ALE-AMR,which combines Arbitrary Lagrangian Eulerian(ALE) hydrodynamics with Adaptive Mesh Refinement(AMR) to connect the continuum to the microstructural regimes.The code is unique in its ability to model hot radiating plasmas and cold fragmenting solids.New numerical techniques were developed for many of the physics packages to work efficiently on a dynamically moving and adapting mesh.We use interface reconstruction based on volume fractions of the material components within mixed zones and reconstruct interfaces as needed.This interface reconstruction model is also used for void coalescence and fragmentation.A flexible strength/failure framework allows for pluggable material models,which may require material history arrays to determine the level of accumulated damage or the evolving yield stress in J2 plasticity models.For some applications laser rays are propagating through a virtual composite mesh consisting of the finest resolution representation of the modeled space.A new 2nd order accurate diffusion solver has been implemented for the thermal conduction and radiation transport packages.One application area is the modeling of laser/target effects including debris/shrapnel generation.Other application areas include warm dense matter,EUV lithography,and material wall interactions for fusion devices. | Alice KONIGES Nathan MASTERS Aaron FISHER David EDER Wangyi LIU Robert ANDERSON David BENSON Andrea BERTOZZI | 2015 | Plasma Science and Technology2015，17，2： | 0 |
