Spherical Ni0.5Mn0.5CO3 is synthesized via carbonate co-precipitation method which uses NH4HCO3 as the precipitator. However, obvious agglomerate of secondary particles occurs when NH4HCO3 is used as the precipitator. The agglomerate particles can result in inferior physical characteristic. An improved carbonate co-precipitation which used NH4HCO3 doped with different proportion of NaOH as a new precipitator is tested in our study. Observed by SEM and Mastersizer, spherical morphology with narrow particle size distribution is synthesized with the proportion of NaOH reaches 10%. The element lin

Abstract:
Abstract Precipitation methods are commonly used for removing phosphorus compounds from wastewater. Chemical precipitation method, based on adding iron, aluminium or calcium salts to the treated wastewater, is often used. Another possible way of precipitating phosphates is metal dissolution method, which is presented in this paper. The main difference between these two methods is how the phosphate precipitating ions are introduced to the wastewater. This paper discusses advantages and disadvantages of the metal dissolution method in comparison with traditional precipitation methods. Difference

Purpose The secondary phase decreased the corrosion resistance because of the segregation of Cr and Mo. Therefore, this paper aims to study the precipitation condition and the effect of secondary phase with volume fraction on corrosion behavior. Design/methodology/approach Secondary phase precipitated approximately from 375°C to 975°C because of saturated Cr and Mo at grain boundary by growth of austenite. Therefore, heat treatment from 800°C to 1,300°C was applied to start the precipitation of the secondary phase. Findings The secondary phase is precipitated at 1,020°C because of segregation

Abstract:
Hot-work tool steels make up an important group of steels that are able to perform with good strength and toughness properties at elevated temperatures and stresses. They are able to gain this behavior through their alloy composition and heat treatment, which relies on the precipitation of alloy carbides to counter the loss in strength as the tempered material becomes more ductile. As demand grows for materials that are suitable for even harsher applications and that show improved mechanical qualities, the steel industry must continuously investigate the development of new steel grades.

The development of tool steels for making and shaping other materials requires a better understanding of the material's properties during manufacture. These high-quality steels include many alloying elements, which give increased hardness during tempering. For producing hardened microstructures, austenite generation is essential. The martensite formed by rapid quenching of austenite followed by tempering helps develop high strength steels. Studying carbide precipitation is a challenge as they are very small in size, present only in small volume fractions and high number densities. The carbide

For correct treatment of heart failure, the mechanism, underlying cause, and any reversible precipitating factors must be identified.

Abstract:
AbstractIn urban environments, sustainable access to water resources depends on many factors, including climatic, social and economic conditions characterizing the surrounding environment. For urban areas in mountain environments these conditions are compounded by stressors resulting from climate change, such as drought, as well as physical remoteness, economic marginalization and poverty, phenomena which impose limits on access to water. Based on Sustainable Development Goals (SDGs) 1, 6 and 13, which were part of the 2030 Agenda for Sustainable Development adopted by UN member states in 2015, in this paper we assess the impact of urban drought on water security in the mountain city of Phuthaditjhaba, South Africa. World Meteorological Organization - Time Series (4.04) climate (precipitation and maximum temperature) data for Phuthaditjhaba were analysed for trends for the period between 1960 and 2019. Trends of Standardized Precipitation Index values and Maximum Temperatures were used to determine how climate change has affected Phuthaditjhaba’s sources of water supply, namely the Fika Patso and Metsimatsho dams. A sample of Landsat images from the same period was used to determine how the two water bodies have responded to the change over time. The results indicate that the two reservoirs have shrunk due to climate change induced drought, thus worsening water insecurity in the city. The results also indicate that mean annual stream discharge is projected to decrease by 39% for the 2016–2045 period. Lastly, based on government reports on water shortages in Phuthaditjhaba and other secondary sources, the results also indicate that though 90% of Phuthaditjhaba’s population has access to potable water, only 55% of the residents have access to reliable water supply. We conclude that without urgent government intervention the future of the livelihoods of the poor majority of Phuthaditjhaba’s residents will remain bleak due to dwindling water resources, making SDG 6, and those influenced by it, unattainable.

Abstract:
Effect of heat treatment on the precipitation behavior of secondary phases in a HR3C austenitic heat resistant steel was investigated. The microstructure of the steel in solution-treated state consists of austenitic matrix and coarse Z-phase particles. After aging treatment at 650–950°C for 1h, M23C6-type carbide precipitates along random grain boundaries. Dense and homogeneous nanosized Z-phase precipitates within austenite grains are obtained by an aging treatment at a temperature between 800 and 900°C for 1h. The high density of dislocation walls produced during the water-cooling process af

Abstract:
Precipitation crystallization is one possibility to produce nano-scaled solid particles from the liquid phase. High nucleation and growth rates are generated by mixing two well soluble reactants and their subsequent reaction to a sparingly soluble product. These primary processes can be very fast. Therefore experimental access to internal parameters is given insufficiently due to predominantly very short process times. Computational Fluid Dynamics (CFD) based methods are a promising tool to gain insight into those inaccessible processes. Unfortunately, 3D modeling of complex precipitation reac

Abstract:
Studies on the bioconversion of whey water formed from chickpea and pea grains in the preparation of protein concentrates have been performed. The serum remaining after precipitation of the main part of the protein was subjected to a symbiotic transformation of Saccharomyces cerevisiae 121 and Geotrichum candidum 977 yeast cultures with the formation of protein-containing products with a mass fraction of protein (52.27-57.90% of DS) and a complementary amino acid composition. A microbial-plant concentrate was used as an additive in the feeding of Wistar laboratory rats. After 25 days of feedin

Abstract:
Abiotic laboratory-based experiments were undertaken to determine the characteristics of mineral dissolution in seawater and thereby examine the potential for ocean alkalinization applications. As part of the mesocosm campaigns on Gran Canaria 2021 (WP5.3) and Bergen 2022 (WP5.4) we contributed to the impact assessment of OAE by conducting labbased experiments, focused on the carbonate chemistry and the stability of alkalinity in TA enhanced seawater. Due to extensive precipitation of secondary Ca-carbonates during the dissolution experiments, the focus of WP5.1 changed from mineral dissolutio

Abstract:
The potential biogeochemical and ecological impacts of ocean alkalinity enhancement were tested in a 5-weeks mesocosm experiment conducted in the subtropical, oligotrophic waters off Gran Canaria in September/October 2021. In the nine mesocosms, each with a volume of about 10 m3 inhabiting a natural plankton community, alkalinity enhancement was achieved through addition of a mix of sodium bicarbonate and sodium carbonate, simulating CO2-equilibrated alkalinization in a gradient from control up to twice the natural alkalinity.

Abstract:
Environmental impacts associated with the mining of carbonatite deposits are an emerging concern due to the demand for critical metals. This study investigates the chemistry of tailings seepage at the former Saint Lawrence Columbium mine near Oka, Québec, Canada, which produced pyrochlore concentrate and ferroniobium from a carbonatite-hosted Nb-REE deposit. Its objectives are to characterize the mineralogy of the tailings and their pore water and effluent chemistries. Geochemical mass balance modeling, constrained by aqueous speciation modeling and mineralogy, is then used to identify reactio
