The present study on the microstructure evolution of hot form-quench (HFQ) AZ31 twin roll cast magnesium alloy attempt to provide an understanding on the grain structure and heterogeneous intermetallic phase formation in the alloy and texture development following the HFQ process. Grain recrystallization and partial d…
Electrochemical noise (EN) was used to study the corrosivity of haze under Tianjin’s urban atmosphere by using two electrochemical corrosion probes made by T91 and Q235B steels. Experimental results indicate that temperature, relative humidity and concentrations of pollutants (PM10, PM2.5, SO2, NO2 and O3) can affect…
Foam injection molding uses physical blowing agents under high pressure and temperature to produce structural foams having a cellular core and a compact solid skin. This technology is particularly interesting for biodegradable polymers, which often present a very narrow processing window, with the suitable processing…
Hydrogen is considered to be a clean, economical and safe renewable energy source that would be ideal to replace fossil fuels, because it is light, highly abundant and its oxidation product (water) is environmentally benign. However, hydrogen is easy to burn (the chemical energy per mass of hydrogen is at least three…
With the increasing of the traditional energy, the utilization of traditional energy and new energy researching is an important direction for the development of the new era. Phase change material, is a new era for the sustainable development of new energy research. The phase change material wrapped into microcapsules…
We report the synthesis of a photocatalytic composite of spherical porous hydroxyapatite (sHAp) and TiO2. sHAp was prepared by a wet method using simulated body fluid as a slurry and was then mixed with a TiO2 sol to obtain the sHAp + TiO2 composite. The TiO2 content of sHAp + TiO2 was ~7.8 wt. %. sHAp+TiO2 showed pho…
This paper presents the results on the development of theoretical methods of evaluation and prediction of mechanical properties of Zr–Nb alloys over a range of strain rates from 10−3 to 103 s−1. The mechanical behavior of coarse- and ultrafine-grained Zr–1Nb (E110) was investigated numerically. The ranges of strain ra…
Electrospinning is one of the techniques used in the fabrication of nanofibers. Polycaprolactone (PCL), is a biodegradable polymer which was commonly electrospun without the presence of nanoparticles as additives and/or filler in the applications such as tissue engineering, biosensors, filtration, wound dressings, dru…
Polymer macrogels with rapid and significant responses to glucose concentration changes were made of a poly(phenylboronic acid) microgel array tethered chemically to bridging polymers.
The lack of phase diagrams and other related thermodynamic information for the silicate slag system with additions Nb and REE seriously restrict the comprehensive utilization of REE-Nb-Fe ore deposit resources in China. In this study, the equilibrium phase relations in the CaO–SiO2–Nb2O5–La2O3 quarternary system at 12…
This paper aims to study the effect of the thermoforming process on the assembly of a newly developed stretchable material for electric circuit and LEDs for manufacturing of automotive lighting. The thermoforming process was conducted using a mould developed based on commercially available automotive lighting product.…
Injection molding of thermoplastic resins is well known to produce volatile organic compounds which can adversely affect operator health, but there is little understanding of particulate emissions. Recent molding of nanocomposites produced no emission of carbon nanotubes, but emission of organic nanoparticulates of un…
CoFe 2 O 4 nanoparticles with 3–30 nm in diameter were synthesized by sol-gel method. The particles were spread as a solid discontinuous layer over planar silicon and TiN substrates by spin coating and covered by 15 nm thick ZrO 2 films by atomic layer deposition. Crystal structures distinctively characteristic of CoF…
New N 2 O controlling strategy: elucidating impact of PGM in by-products formation and then optimizing catalyst formations with rational PGM utilization.
Recently, the development of electronic and electric devices has caused an increase in the level of electromagnetic radiation; therefore, the demand for protection against this danger has increased. There are many ways how to ensure the protection of device against electromagnetic interference; however, this paper is…
ABSTRACT Biochar as a soil amendment has been shown to improve soil quality and crop growth. However, biochar’s effect on urea-N use efficiency in long term is not well elucidated. Here we studied urea-N (15N isotope) allocation in plants and soil in the presence of maize (Zea mays L.) stover biochar (equivalent to 46…
partition coefficient and (ii) the retention factor on thin layer chromatography. This concept could potentially be extended to test drugs or pharmacophores exhibiting any photoactive moiety.
An approach of machine learning called Deep Learning is utilized for construction of a prediction method of microsegregation behavior in Fe-based binary alloys with solute atoms of C, Si, Mn and P. Training data for the machine learning are obtained by quantitative phase-field simulations for directional solidificatio…
The paper outlines different solutions to address the problem of progressive collapse when designing buildings and structures and proposes possible modes of progressive collapse of structural systems. It presents the requirements stipulated by regulatory documents for assessing progressive collapse of buildings. It ov…
The special aspects of the edge morphology's formation were investigated under the diamond grinding for the si3N4-ceramics species, the crumbling types and geometrical parameters were defined. The interrelation between the grinding depth, the longitudinal and transverse motion and the crumbling geometrical parameters…
