Nickel production for electric vehicle batteries increases by 30% every year. As the country with the most nickel production in 2021, Indonesia will operate six nickel refining plants with High-pressured acid leaching technology and one development of Step Temperature Acid Leach technology. Problems arise with many hydrometallurgical-based nickel refining plants where the leach residue will continue to accumulate and potentially pollute the soil environment. Lateritic nickel leach residue has a high Fe content reaching 44.45% in the form of hematite and an S content of around 1.3%. Besides, demand growth in the iron and steel industry is greater than the availability of its raw materials. Thus, secondary sources for raw materials for the iron and steel industry are needed. The maximum S content for steel raw materials is 0.1%, so the sulfur content in leach residue must be removed. This research focuses on removing sulfur content in lateritic nickel leach residue by roasting at a temperature of 500 °C until 1100 °C. The experiment was continued with reduction roasting at various temperature profiles. The reduced phase of the roasted leach residue sample is then compared with the reduced phase of the initial leach residue sample. Sulfur content decreases with increasing roasting temperature. Sulfur content reaches ~0% at a roasting temperature of 1100 °C. The optimum initial sample reductive roasting temperature of lateritic nickel leach residue was 1400 °C with 95.9% Fe content and 0.1% S in metal. The optimum reductive roasting temperature for 1100 °C roasted samples was 1200 °C with 94.6% Fe content and 0% S. Roasting treatment can reduce the optimum temperature for the reduction roasting process.

In this paper, we take a creative look at the effect of cracking on the buckling of graphene sheets. We introduced a significant improvement in molecular mechanical calculations that more accurately examine the behavior of atomic bonds during the instability of nanostructures in the presence of defects. A molecular mechanics method based on the modified couple stress (MCS) theory to consider the size effect on the graphene plate is introduced. Primary cracks with different lengths, orientations, and numbers were examined. For each crack, buckling parameters such as critical load and buckling modes of graphene sheets were investigated. This model has better computational performance and less computational compactness than other models. Our studies show that cracks perpendicular to the load direction have a greater effect on buckling parameters, including modes and critical buckling load than cracks aligned to the critical load. Increasing the crack length will further reduce the critical buckling load. The effect of the number of cracks in two directions in buckling parameters was investigated. Increasing the number of cracks always decreases a critical buckling load. Increasing the number of cracks affects the first buckling mode more than others. The study of the eccentricity of cracks shows that with increasing the eccentricity distance, in cracks perpendicular to the loading direction, the critical buckling load will be further reduced. However, for cracks aligned with the load direction, increasing the eccentric distance has less effect on reducing the critical buckling load.

This study reports the adsorption capacity of copper Cu (II) and nickel Ni (II) of biochar obtained from peanut shell. The kinetics and equilibrium of biosorption were examined in detail. Two kinetic models (pseudo-first order and pseudo-second order) were used to correlate the experimental data and to determine the kinetic parameters. Two well-known adsorption isotherms were chosen to describe the biosorption equilibrium (Langmuir and Freundlich). The equilibrium isotherms showed that modified peanut shells possess high affinity, sorption capacity for Cu (II) and Ni (II) ions, sorption capacities of 37.443 mg/g Cu (II) and 28.626 mg/g Ni (II) biomass, respectively. All results showed that peanut shells biomass is an attractive, alternative low-cost bio sorbent for removal of heavy metal ions from aqueous media, therefore biomass materials find good application prospects.

There are several energy drinks available in the market such as Red Bull, Sting, Rebound, Power Up! Triple X Energy Drink, and so on. After the Red Bull drink was introduced in the market in1990s, Energy drinks started to gain popularity and afterwards it became a common name especially among teenagers and young adults [1]. Most energy drinks are caffeinated nonindulgent beverages that are professed to give an additional increase in energy for day-by-day work, increase alertness, and improve athletic performance and mood. There are even certain shreds of evidence present to substantiate these claims, but the effects of these drinks on mental and physical health cannot be neglected. There are reports of adverse events such as insomnia, anxiety, cardiovascular events, seizures, tachycardia, type-2 diabetes, and even death are associated with the consumption of these drinks [2]. This review will focus on energy drinks, their ingredients, health risks associated with these drinks, and will also suggest some recommendations such as changes in marketing, providing education to children regarding adverse effects of these drinks, and further research should be carried out in this domain.

Particulate matter (PM) concentrations are significantly higher in urban railway tunnels (178.1 μg/m3) than in metropolitan areas (49 μg/m3). Nitrogen oxide (NOx) concentrations, which are a direct cause of lung disease, have been found to exceed the atmospheric standard of the Ministry of Environment in tunnels in Korea. Dust generated by trains is scattered at high speed along tunnels, making filtration difficult. The development of filters that can be used in tunnels is urgently required. In this study, the results of using an activated carbon filter (ACF) were analyzed and compared with the laboratory-scale PM adsorption using functional activated carbon non-woven fabric filters (Cerebasel, Cerecore) that can be manufactured in Korea. The fine PM concentration, filter depth, and flow rate in the tunnel were the experimental variables. We compared PM concentrations before and after the filter experiments, and calculated the PM removal efficiency to determine the optimal conditions.

The virulent Escherichia coli strains are responsible for extraintestinal infections. However, no past studies have been undertaken via the presence of virulence genes, ability of biofilms formation and the frequency of Escherichia coli pathovars recovered from different butcheries and slaughterhouses in Tunisia. The aims of this study was to investigate 1-) the prevalence of pathogenic E. coli strains isolated from bovine, ovine, and poultry meat in Tunisia, 2-) to determinate the antibiotic resistance profiles, and 3-) to determine their biofilm-forming ability by three phenotypic methods .Totally, 36 E. coli isolates from meat of healthy animals (bovines, ovine, and chickens) collected from different butcheries and slaughterhouses were investigated by searching by PCR genes encoding virulence factors (hlyA, stx1, stx2, fimH, papC, eaeAet papG allèle III, ibeA, iutA, and antibiotic susceptibility testing. Biofilm production was detected by three phenotypic: Congo Red Agar (CRA) method, tube method (TM) and tissue culture plate (TCP) method. In addition, the genetic relationship of isolates was determined by PFGE.

Cardiovascular disease (CVD) is one of the most common causes of mortality and morbidity worldwide.Coronary artery disease (CAD) is the most common form of CVD. To prevent CAD we need to assess the risk of future CAD in all patients referred for cardiovascular care, but each of the several available systems for risk assessment has its own limitations. This study was designed to determine whether vitamin D deficiency is a potential risk factor for CAD.
