Market Risk of Lithium Industry Chain—Evidence from Listed Companies

Lithium, a crucial raw material for new energy vehicles, is experiencing significant market price fluctuations due to escalating geopolitical conflicts, periodic mismatches in supply and demand, and increased attention to lithium resources from countries around the world. These factors may adversely affect the development of the new energy vehicle industry. This paper adopts the TVP-VAR-DY model, which measures dynamic spillover effects by allowing for variance changes through the estimation of a stochastic Kalman filter, thereby measuring risk spillover among upstream and downstream firms in the lithium industry chain. We selected 16 listed companies and six regional financial markets as the research sample, with the sample period from 4 July 2018, to 30 June 2023. The main conclusions are as follows: Between 2018 and 2020, the overall risk spillover in the lithium industry chain demonstrated a declining trend, though it experienced a sudden surge in 2020 as a result of the COVID-19 pandemic. This increase was followed by a gradual decline as the global economy improved and market stability was restored, leading to a reduction in risk aversion. Regarding the reception of risk spillovers, upstream firms exhibited a generally consistent level of directional risk spillovers, whereas downstream firms experienced more significant fluctuations. Chinese firms exhibited a higher level of received risk spillovers compared to their international counterparts, with less variation in these spillovers. From the perspective of risk spillover effects, significant variations were observed between firms in both the upstream and downstream markets. Chinese firms exhibited a higher level of risk inflow than international firms, with more pronounced changes in risk spillovers. Upstream enterprises should enhance their market competitiveness to mitigate the adverse effects of economic uncertainty. Downstream enterprises can alleviate the rise in raw material costs resulting from market price fluctuations through strategic cooperation. Additionally, the government should increase the market supply of resources, which will contribute to the establishment of a more robust lithium industry chain system.

Performance of preserved alpha prime belite phase within belite-ye’elimite-ferrite clinker

Belite-ye’elimite-ferrite (BYF) cement has garnered significant interest as an alternative to ordinary Portland cement (OPC) due to its lower limestone content, early-age strength development, and improved durability. However, the main challenge to the commercial production of BYF cement is the requirement for large quantities of costly aluminous raw materials. The introduction of alpha prime belite (α'C2S) to BYF clinker would minimize production costs while maintaining mechanical properties. Herein, α'C2S containing BYF clinkers were synthesised and analysed to determine their properties and hydration characteristics. The clinker samples were synthesised using a previously reported clinkering technique wherein a sulfur-containing atmosphere was used, with a raw mix design including additions of a combination of boron, potassium, and sodium-containing doping agents. Preliminary data showed adequate amounts of α'C2S were preserved reaching more than 40 wt.% of total clinker composition. Moreover, the heat release curves revealed enhanced hydration kinetics for the modified clinkers compared to the unmodified ones. While there was a noticeable improvement in ettringite precipitation upon hydration, the precipitation of strätlingite remained the same after doping. The experimental findings showed high potential for the existence of low ye’elimite BYF clinker formulations as part of the wider portfolio of OPC clinker alternatives.

USE OF PULVERIZED COAL FUEL FOR PREHEATING SCRAP

Preheating of scrap in the converter is an actual area of ​​research in modern metallurgy. The growing requirements for energy efficiency and the reduction of raw material costs encourage the development of new technological solutions to increase the share of scrap metal in the charge of converter production. Traditional methods are often limited to the use of no more than 25% of scrap, which is associated with difficulties in its uniform heating and the possible formation of a liquid phase as a result of local overheating. The work evaluates the effectiveness of traditional and experimental technological solutions, such as two-tier and fuel-oxygen nozzles. The stages of ignition and burning of lump coal and pulverized coal fuel and their influence on the uniformity of scrap heating were studied. Experimental studies have shown that with a specific oxygen consumption of 1-1.35 m³/kg of pulverized coal fuel, uniform heating of scrap metal is ensured without the risk of melting the upper layers. During the use of a fuel-oxygen lance, the following features of heating scrap metal using pulverized coal fuel, which was blown in an oxygen ring shell, were discovered: - during the combustion of coal dust in an oxygen environment, due to the significant total surface of coal particles, the bulk of volatile СmНn does not have time to separate before the beginning particle ignition, and carbon burns at the same rate as volatiles. This contributes to the formation of high-temperature torches with great luminosity, which effectively affect the surface of the scrap; - the coefficient of use of blown oxygen and pulverized coal fuel is significantly higher than when using lump gas coal during heating of any duration. This is due to the greater luminosity of the formed torches, which contributes to the intensive absorption of thermal energy by the surface of the scrap; - the time required to heat the surface of the scrap metal to the specified temperature is reduced, which allows you to avoid the formation of a liquid component that can lead to undesirable consequences, such as uneven heating or damage to the converter lining. Based on the results of experimental studies, the relationship between the specific oxygen consumption and the flame temperature was established. The ability to control the temperature regime during the heating of scrap metal indicates the prospects of using a fuel-oxygen nozzle made of PVP to optimize the converter production process. For the full implementation of the technology, additional research and industrial testing are needed to optimize processes and increase production efficiency.

Application of waste fly ash and graphite powder used as backfill materials in vertical ground heat exchangers

Backfill material plays a significant role in heat transfer between the ground heat exchangers (GHEs) and surrounding soil. Fly ash is the fine ash wasted from coal combustion in thermal power plants, which may cause a serious of problems including air, water and soil pollution. To fully utilize the waste resources and improve the thermal performance of backfill material, a method of using waste fly ash and graphite powder is proposed, and the feasibility of using them as backfill material is investigated via laboratory and field test, in which the economic aspect is taken into consideration. The results indicate that the highest thermal conductivity of thermally enhanced backfill material could be increased to 2.391 W/(m·K) via laboratory test, with a growth rate of 23.69%, in which the mass ratio of graphite reaches 10% meanwhile guaranteeing the workability of fresh mortar. Heat transfer rates could be enhanced by 27.22% compared with traditional backfill material of natural sand via field test, corresponding to a highest heat transfer rate of 55.80 W/m. The economical value could be achieved through the lower cost of raw material and the reduction of drilling depth.

Severe plastic deformation of Mn-Al permanent magnets

Manganese-aluminum permanent magnets are promising candidates to fill the cost and performance gap between lower-performance bonded ferrites and high-performance magnets based on rare-earth elements. This is due to the favorable combination of saturation magnetization and magnetocrystalline anisotropy in the Mn-Al τ phase combined with low raw material cost. However, the τ phase is metastable and prone to decomposition at high temperatures, making processing by conventional milling and sintering difficult. Severe plastic deformation (SPD) is an alternative processing route to control the microstructure of a material by applying very high amounts of strain. In this study, equal-channel angular extrusion (ECAE) and high-speed high-pressure torsion (HS-HPT) were both tested as SPD processing routes. ECAE improved magnetic energy product, (BH)max, by 220% by refining the grain size and imparting a high density of dislocations. HS-HPT enabled a rapid phase transformation from the high-temperature ε phase to the τ phase but lowered Hci, making it better suited to soft magnet processing.

Exceptional tensile ductility and strength of a BCC structure CLAM steel with lamellar grains at 77 kelvin

The low-temperature tensile brittleness of body-centered cubic (BCC) metals and alloys can seriously compromise their service applications. In this study, we prepared a BCC structured China low activation martensitic steel (CLAM) steel with lamellar grains by regulating the rolling and heat-treatment processes, successfully reversing the decreasing trend of ductility in the steel with decrease in temperature. Compared with current face-centered cubic (FCC) structural steels and high-entropy alloys, the lamellar grained CLAM steel exhibits an excellent synergy of strength and ductility at 77K, but with lower raw material costs. The superior low temperature ductility of the lamellar grained steel can be attributed to an increase in grain strength at low temperatures which promotes the propagation of layered tearing cracks; this in turn leads to a significant increase in the necking area of the steel, thereby compensating for the decrease in ductility. We conclude that our lamellar grain structures can be utilized to significantly enhance the low-temperature tensile ductility of BCC metals and alloys, thereby expanding their service range to cryogenic temperatures.

Multifunctional Copper Nanoclusters for the Detection of pH and Berberine Hydrochloride.

The copper nanoclusters (CuNCs) have been garnered significant attention owing to their low cost raw materials, outstanding optical properties, environmental friendliness and good biocompatibility. In this study, copper nanoclusters stabilized by Acid Chromic Blue K (ACBK-CuNCs) were synthesized. The optimal excitation wavelength of the synthesized ACBK-CuNCs is 344nm and the optimal emission wavelength is 460nm. Its fluorescence intensity can be retained for more than two weeks, which indicated that the antioxidant capacity of the synthesized ACBK-CuNCs is strong. It was noted that the fluorescence intensities of the synthesized ACBK-CuNCs significantly increased with the decrease of pH. There are good linear correlation between the fluorescence intensity ratio of the system to the fluorescence intensity of the original solution (F/F0) and the pH of the medium. Based on this finding, a method for fluorescence analysis to detect the pH of solution was developed. Additionally, it was discovered that the fluorescence intensity of CuNCs could be quenched efficiently by Berberine hydrochloride (BH), and there is a favorable linear relationship between the change value of fluorescence intensity of CuNCs ((F0 - F) / F0) and the concentration of BH. This gave rise to the establishment of a fluorescence analysis method for determining the concentration of BH. Simultaneously, visual quantitative detection for BH and pH was achieved based on smartphones and colorimetric analysis software using ACBK-CuNCs as the fluorescent probes.

Lead ion adsorption by biochar manufactured from downed timber: the effect of downed timber maturity and environmental exposure period

ABSTRACT Downed timber is valuable for manufacturing biochar in environmental remediation applications due to the low cost of raw materials and low-temperature manufacturing process. Loblolly pine (Pinus taeda L.) trees at different maturities (15-, 30-, and 39-year-old) with 0, 6, and 12 months of local environmental exposure in the southeastern region of the US were collected for biochar manufacturing. The biochar samples were characterized for their physicochemical properties, including morphologies, elemental compositions, surface functional groups, carbon structure, pH, electrical conductivity, and specific surface area. The Pb2+ adsorption isotherms were measured. The results indicated that the biochar physicochemical properties, affected by the tree maturities and the environmental exposure periods, significantly impacted the Pb2+ adsorption capacity. The Pb2+ adsorption capacity of biochar increased with the environmental exposure of wood for 6 months, followed by a decrease for biochar made from wood with an environmental exposure of 12 months. A recommendation can be made that downed timber collected up to a 6-month environmental exposure period can manufacture biochar with superior performance regarding adsorbing Pb2+ in water systems. The research outcome offered insights for the biochar manufacturing community to prepare forest feedstock for biochar production with better performance in Pb2+ adsorption.

Application and practice of LILCEO sintering proportion optimization algorithm in sintering plant

Purpose To ensure the stable operation of ironmaking process and the quality and output of sinter, the multi-objective optimization of sintering machine batching process was carried out. Design/methodology/approach The purpose of this study is to establish a multi-objective optimization model with iron taste content and batch cost as targets, constrained by field process requirements and sinter quality standards, and to propose an improved balance optimizer algorithm (LILCEO) based on a lens imaging anti-learning mechanism and a population redundancy error correction mechanism. In this method, the lens imaging inverse learning strategy is introduced to initialize the population, improve the population diversity in the early iteration period, avoid falling into local optimal in the late iteration period and improve the population redundancy error correction mechanism to accelerate the convergence rate in the early iteration period. Findings By selecting nine standard test functions of BT series for simulation experiments, and comparing with NSGA-?, MOEAD, EO, LMOCSO, NMPSO and other mainstream optimization algorithms, the experimental results verify the superior performance of the improved algorithm. The results show that the algorithm can effectively reduce the cost of sintering ingredients while ensuring the iron taste of sinter, which is of great significance for the comprehensive utilization and quality assurance of sinter iron ore resources. Originality/value An optimization model with dual objectives of TFe content and raw material cost was developed taking into account the chemical composition and quality indicators required by the blast furnace as well as factors such as raw material inventory and cost constraints. This model was used to adjust and optimize the sintering raw material ratio. Addressing the limitations of existing optimization algorithms for sintering raw materials including low convergence accuracy slow speed limited initial solution production and difficulty in practical application we proposed the LILCEO algorithm. Comparative tests with NSGA-III MOEAD EO LMOCSO and NMPSO algorithms demonstrated the superiority of the proposed algorithm. Practical applications showed that the proposed method effectively overcomes many limitations of the current manual raw material ratio model providing scientific and stable decision-making guidance for sintering production operations.

Annual Workplan and Budget (AWP&B) are prepared annually by public organization as required by the government policy for funds allocation by the treasury which presents a focused role and a determined direction that estimates organization finances against her activities in a financial year. This study analyzed the effect of AWP&B on the performance of County Forest Conservancies (CFCs) in Kenya. Specifically, the study derived a correlation between funds allocation and the performance of CFCs. A descriptive research design was employed to analyze the AWP&B on the performance of CFCs. The result of the correlation between funds allocation and performance of CFCs with the application of the Linear Programming (LP) model of optimization provided optimal solution on performance that will lead to lasting output, especially the allocation of enough funds for better implementation of the activities towards the achievement of planned targets. In conclusion, funds allocation and performance of CFCs correlated with established constraints of budget, raw materials cost, labour cost, and machine operation cost due to limited fund allocation, which had a negative effect on performance in terms of the level of activities done. LP model clearly provided optimal solutions to the viability of carrying out seedling production and other activities in the counties. To this effect, the LP model is to be enhanced to help the organizations optimize decisions on variables to solve problems of limited resources and multiple objectives incurred when implementing AWP&B.

The results revealed the highest conversion and product rate, with the lowest energy cost, side product, and bare module cost, CBM. The decision variable plots indicate that the reactor’s pressure significantly affects the optimal solution. This study provides valuable insight into optimizing CH3OH production.

A synergistic strategy for formulating a facile and cost-effective soybean protein-based adhesive via co-crosslinking and inorganic hybridization

Soybean protein-based adhesives (SPAs) are environmentally friendly, sustainable, and renewable, but their wide applications are limited by moderate bonding strength, poor water resistance, undesirable flame retardancy, and high costs. Inspired by the organic-inorganic hybridization of oysters, a facile and cost-effective SPA was developed in this study via co-crosslinking branched melamine-urea-glyoxal (MUG) and polyamidoamine-epichlorohydrin (PAE) resins, as well as inorganic hybridization by using the mineral bentonite (BT). Low-cost branched MUG resins that could efficiently co-crosslink with PAE resin and substitute for 40 % expensive PAE resin were optimally copolymerized from melamine, urea, and glyoxal. This approach provided more co-crosslinkable sites for constructing denser multiple covalently-crosslinked SP-PAE-MUG networks via MUG-protein crosslinking and MUG-PAE co-crosslinking. 30 wt% of low-cost layered mineral BT was intercalated to further reinforce the mechanical properties and flame retardancy of SPA by forming a compact organic-inorganic hybridized structure. The coordination of MUG-PAE co-crosslinking and BT inorganic hybridization resulted in a cost-effective and robust SPA with a 61.2 % higher dry strength, a soaked wet strength of 126.0 %, an aged wet strength of 86.0 %, a residual carbon content after combustion of 94.3 %, and reduced the raw material cost for formulating adhesive by 19.5 % compared with controlled commercial SPA. This novel strategy highlights the potential applications of the SP in bio-adhesives and bio-composites with excellent bonding strength, water resistance, and flame retardancy.

METHODS: Engineers use the method of changing working bodies designed as layouts aiming to turn the machines into the modules capable of performing various types of operations based on working conditions. Thanks to this method, sets of individual working bodies and combinations are prepared for any kind of conditions (soil, climate, etc.). In addition to the advantages, this system has a number of disadvantages. One of these is that at the factory-built modules that are part of the original basis of the unit cannot be fully adapted to environmental conditions and economic factors of production. In this regard, combination of structural layouts and selection of the necessary parameters become problem causing. It is difficult to choose necessary parameters that are capable of ensuring minimal losses and adjusting the unit to the necessary operating mode. The objects of study are the devices and production processes, the main task of which is performing tillage and sowing operations. The practical value of this study presented in the form of: building the algorithm capable of structuring the analysis and synthesis of the structural layout of the tillage-sowing unit to find the working links for various types of unit functions; finding the methods and improved combinations of working bodies, comparison of similar mechanical analogues with the original properties of systems. RESULTS: When studying the studies of Wilde, who gave a description of the combined units, as well as the studies of Runchev, who determined the generalization of the combined machines, the relevant typology of agricultural machinery was developed. In this typology, one of the most important characteristics is multifunctionality, which has developed from the need for the versatility of units and the compilation of combinations of several units. The developed technology contains a number of characteristics that are fundamental for the choice of agricultural machinery. CONCLUSION: As a result of the study, it was determined at which velocity of the unit the system is balanced.

Area-based composition predictions of materials fabricated using simultaneous wire-powder-directed energy deposition

Functionally graded materials are an emergent method for designing components with programmable site-specific material properties. These materials are typically fabricated using metal additive manufacturing tools by simultaneously feeding multiple wire and/or powder feedstocks at various rates to achieve spatial composition change. The wire-powder-directed energy deposition (WP-DED) technique is of particular interest for many functionally graded material applications by balancing the low raw materials cost of wire with the high resolution of powder. However, feeding wire and powder are inherently different processes since all extruded wire enters the melt pool, while much of the blown powder is scattered, which makes determining the composition of the build challenging. In this study, we devise a simple area-based measurement method for estimating the composition of WP-DED structures. WP-DED single beads are printed using 309L stainless steel wire and commercially pure Fe powder at five wire feed rates (0.5, 0.75, 1.00, 1.25, 1.50 mm/mm) and five powder feed rates (2, 4, 6, 8, 10 rpm). Characteristic defects including interface gaps and macrosegregation (lack of mixing) tendencies are examined. High powder feed rates (8, 10 rpm) result in interface gaps at all wire feed rates, but smooth deposition and complete mixing is achieved at low powder feed rates, particularly with lower wire feed rates as well. The area-based composition measurement method is within ±20% of energy dispersive x-ray spectroscopy measurements for all samples, showing its effectiveness as a rapid composition estimate for WP-DED materials development.

Sustainable soil rehabilitation with multifunctional mandarin orange peel/tobermorite composite hydrogels: Water retention, immobilization of heavy metals, fertilizer release and bacterial community composition

Traditional hydrogel applied in soil tends to be unacceptable due to the high cost of synthesis raw materials and difficulty in degradation. To enhance water holding, adsorption of heavy metals and substrate fertility, this work developed a novel composite hydrogel (MxTy-CH) prepared from mandarin orange peel (MOP) and tobermorite (TOB). By arranging the enhancement of MOP and TOB, the water absorbency (from 171.23 g/g to 204.29 g/g), water holding (66.77 %, 144 h), adsorption characteristics (Cd2+ 339.93 mg/g; Pb2+ 1743.44 mg/g) and fertilizer slow-release performance (0.938 % released in 6 days) were significantly enhanced. The results indicated that the addition of MOP and TOB contributed to an enrichment in the number of –COOH and –OH groups contained in the system. Additionally, the adsorption behavior of cadmium/lead on MxTy-CH was more consistent with the pseudo-second-order kinetics and Langmuir isotherm models. The regeneration test results suggested that the adsorption removal rate of cadmium/lead by MxTy-CH remained stable after 5 cycles. Fish toxicity tests indicated that MxTy-CH was biocompatible and would not cause obvious physiological toxicity to fish organisms. The MxTy-CH treatment group performed better than control group in Cd(II) and Pb(II) passivation performance in soil with mung beans. Changes in the microbial community composition and structure after MxTy-CH treatment in soil provided demonstration for stimulated C and N cycling in soil, suggestive of enhanced soil quality. The abovementioned further proves the considerable application potential of MxTy-CH in plant growth and rehabilitation of cadmium and lead contaminated soil.
