A laminated structured 2205 duplex stainless steel (DSS) with graded grain size was prepared via aluminothermic reaction and subsequent hot rolling deformation of 80% at 1000°C, its mechanical properties, strengthening toughening mechanism were studied. Our materials have extraordinary elongation 54% high tensile strength 990 MPa. The lamellar structure is characterized heterogeneous lamella au...

Plant nutrition has a vital role in crop production. This study was performed to investigate the effects of different application methods some nutrients (nano Fe, Zn, and Ti), gibberellin on yield, morphophysiological grain protein white beans 2018 as factorial experiment randomized complete block design with four replications. Experimental factors included seed priming (hydropriming, priming, ...

Nano-Sn/C composites are ideal anode materials for high energy and power density Li-ion batteries. However, because of the low melting point of Sn and the tendency of grain growth, especially during high temperature carbonization, it has been a significant challenge to create well-dispersed ultrasmall Sn nanoparticles within a carbon matrix. In this paper, we demonstrate an aerosol spray pyroly...

Understanding the grain size-dependent failure behavior of polycrystalline graphene is important for its applications both structurally and functionally. Here we perform molecular dynamics simulations to study the failure behavior of polycrystalline graphene by varying both grain size and distribution. We show that polycrystalline graphene fails in a brittle mode and grain boundary junctions se...

The ability to produce large, continuous and defect free films of graphene is presently a major challenge for multiple applications. Even though the scalability of graphene films is closely associated to a manifest polycrystalline character, only a few numbers of experiments have explored so far the electronic structure down to single graphene grains. Here we report a high resolution angle and ...

It is reported that the ductility and strength of a metal matrix composite could be concurrently improved if the reinforcing particles were of the size of nanometers and distributed uniformly. In this paper, we revealed that gas atomization solidification could effectively disperse TiB2 nanoparticles in the Al alloy matrix due to its fast cooling rate and the coherent orientation relationship b...

The microstructure, mechanical properties, and hydrogen permeation behavior of hot rolled enamel steel were investigated. Three coiling temperatures were adopted to gain different sizes of ferrite grain and TiC precipitates. The results show that a large number of interphase precipitates of nano-sized TiC can be obtained at coiling temperatures of 650 and 700 °C, while a few precipitates are fo...

In the Structuring Nanotechnology Knowledge project, a material-independent platform for supporting development of innovative nano-materials is developed. The platform is called “Structured Knowledge Platform for Nano-materials and Products”. It consists of various kinds of resources. However, domains and grain sizes of the resources are different from each other. Therefore, we need a consisten...

Context. Carbonaceous nano-grains play a fundamental role in the physico-chemistry of interstellar medium (ISM) and especially photon-dominated regions (PDRs). Their properties vary with local physical conditions affect chemistry dynamics. Aims. We aim to highlight evolution carbonaceous three different PDRs propose scenario dust as response conditions. Methods. used Spitzer/IRAC (3.6, 4.5, 5.8...
