Additionally, in situ TEM heating experiments at 550 °C revealed that the formation of V-phase occurs due to a nucleation and growth mechanism following the dissolution of Si particles and nanoscale (Al,Si)3Sc precipitates.doi:10.1016/j.jallcom.2020.158511Jayshri Dumbre a...
It is suggested that, the use of 0.18%Sc has more-or-less the same grain refining efficiency of 0.15%Ti added in the form of Al–Ti–B master alloy i.e., reduction in the grain size by about 85% and an increase in the alloy strength by about 30%. For a given solidification rate...
The court stated that since elections after the dissolution of a provincial assembly were to be held within a stipulated period of time, the president or the governor “must discharge the constitutional responsibility of appointing a date for the said election swiftly and without any delay and with...
The dissolution of C O2 alone is not expected to cause a significant decrease in the solubility of sodium chloride in water at elevated pressure/temperature (Sawamura et al. 2007; Zhao et al. 2015). However, the solu- bility of other salts (e.g., calcium carbonate) are strongly...
摘要: CSV file with scientific output of 102 countries (rows) by 27 major Scopus/SCImago subject areas, from 1996 to 2006. Data extracted from SCImago Journal & Country Rank (scimagojr.com).DOI: 10.5281/ZENODO.7544 被引量: 7 年份: 2013 ...
The resulting structure (Fig. 4a and Supplementary Fig. 4) consists of a water-solvated Ca2+ species within the 1W film as an outer sphere complex. Using the Blue-Moon sampling method41, we examined the free energetics of the dissolution process by computing the poten- tial of mean force...
Sc-CO2containing 20% ethanol as compared to only 39% without co-solvent. Zhang et al. (2002) postulated that the addition of co-solvent makes the dissolution process in Sc-CO2becomes less exothermic. However, there are difficulties in separating co-solvent from the product after extraction (...
performed a series of first-principles calculations to predict the dissolution and diffusion properties of interstitial hydrogen in tungsten and the influence of temperature and the defect-trapping effect29. Hydrogen atoms are extremely difficult to aggregate at interstitial sites to form a stable cluster...
This study aims to elucidate the mechanism of Sc2O3 reduction using Al–Ca alloys. However, the oxidation state of scandium in the CaO–CaCl2 flux must be determined to confirm the ionic reaction of scandium within the flux. The oxidation refining mechanism suggests that the dissolution of vari...
Most of current SDS removal strategies are time consuming, laborious, and have low reproducibility. Here, we describe a method, SDS–cyclodextrin (CD)-assisted sample preparation, by which CD can bind to SDS and form CD–SDS complexes in solutions, allowing for direct tryptic digestion. We ...
