Summary: Gastrointestinal anthrax, caused by Bacillus anthracis, is an important but neglected disease in remote areas of the Indian subcontinent and Africa. This study evaluated the anti-Bacillus anthracis properties of commonly used plants in traditional medicine, with garlic extract showing the most promising bactericidal activity. Further research is needed to explore the potential application of garlic extract in preventing anthrax incidences in endemic areas.

Summary: This work reports the corrosion inhibition performance of modified hybrid particles reinforced into a polyolefin matrix. The modified hybrid particles, synthesized via a chemical precipitation process and coated with cerium oxide, were added to the polyolefin matrix at a concentration of 1 wt.%. Various analytical techniques were used to characterize the synthesized and modified hybrid particles. The results demonstrate the promising corrosion inhibition performance of the modified coatings, attributed to the efficient release of the inhibitor from the hybrid particles.

Summary: In this study, efficient and reliable in vitro induction protocols of autotetraploid garlic were established. The obtained autotetraploid garlic exhibited stable and remarkable dwarfness effect and other morphological and cytological changes. Furthermore, the level of phytohormones was significantly lower in autotetraploids, while organosulfur compounds accumulated a higher content significantly. These findings are of great importance for artificial polyploid breeding and investigation into the consequences of whole-genome doubling.

Summary: Two neonicotinoid derivatives, IMT and IMP, have been developed as copper corrosion inhibitors in a NaCl solution, with inhibition efficiencies greater than 97% at 298 K. These compounds can form a protective film on the copper substrate and create a more hydrophobic surface to shield corrosive ions, making them potential alternatives for corrosion inhibitors in harsh industrial seawater systems.

Summary: Garlic has been traditionally used as a food ingredient and remedy for diseases, with black garlic gaining popularity recently. A study found that major components in black garlic extract include sulfur derivatives, saccharides, peptides, and organic acids, showing antioxidant, metabolic, and hepatoprotective effects in cancer cells, as well as inducing maturation of acute myeloid leukemia cells. These findings suggest that black garlic consumption could potentially prevent metabolic and tumor diseases.

Summary: Disinfection is crucial in the production of drinking water, and free chlorine is commonly used for this purpose. Brazilian researchers investigated the corrosion resistance of ASTM A1018 steel in a solution containing 3.0 mg/L of residual free chlorine. The study revealed that the corrosion product layer formed in this solution has a bilayer structure, with an adherent magnetite layer as the internal layer and a gel-like and non-adherent lepidocrocite layer as the top layer. Electrochemical tests showed that the steel had low corrosion resistance and acted as a porous electrode, following the de Levie theory only in the high frequency region.

Summary: The corrosion and hydrogen-induced cracking (HIC) resistance, as well as hydrogen permeation behavior, of two API 5L X65 steels with different amounts of Mn and microalloying elements were compared. The corrosion behavior of both steels showed no significant differences in each medium, but their corrosion resistance was lower in the sour medium. The low Mn steel exhibited better resistance to hydrogen-induced failures, which could be attributed to the higher content of Nb carbides.

Summary: The effect of a post-treatment for a short time in 50 mM Ce(NO3)3 solution on the corrosion of AA2024-T3 anodized in tartaric-sulfuric acid was investigated. The tests showed that post-treatment at 50 degrees Celsius in an H2O2-containing solution improved the performance of the samples. Microstructural characterization revealed the presence of Ce oxy-hydroxides on the surface and within the pores of the anodized layer, indicating their preferential interaction with defective sites at both micro and nanoscale. The presence of Ce-species near corrosion products indicated active corrosion protection by Ce ions.

Summary: This work evaluates the electrochemical behavior and morphological characterization of a system consisting of a cerium conversion layer, a hybrid sol-gel coating, and the two coatings applied sequentially (duplex) for corrosion protection of WE43 Mg alloy. Different characterization techniques showed that the previous application of the conversion coating improved the surface coverage by the hybrid coating. Fitting impedance diagrams with electrical equivalent circuits allowed proposing a physical model for the coating, demonstrating its interaction with the porous Mg oxide/hydroxide layer. Self-healing properties of the duplex coating were also revealed.

Summary: This research aims to evaluate the potential of using graphene oxide modified with polycarboxylate-based superplasticizer as a corrosion inhibitor for reinforcement steel. The study incorporated 0.002 and 0.05 wt.% of graphene oxide (GO) in the cement extract and used various techniques to investigate the inhibitive effect of GO against steel corrosion. The results showed that the 1:8 ratio of GO: polycarboxylate achieved the best dispersion of GO in the cement extract, and the 0.002 wt.% GO content exhibited the most promising corrosion inhibition effect for steel in the studied environment.

Summary: In recent years, studies have focused on improving hybrid silane films obtained through the sol-gel route by modifying them with natural corrosion inhibitors. This study aimed to evaluate the corrosion resistance of a modified TEOS/GPTMS hybrid film treated with garlic peel and cocoa shell powders on SAE 1008 carbon steel. The film showed improved anti-corrosive properties when compared to a film without natural inhibitors.

Summary: Garlic peel, as a green inhibitor, demonstrated efficient corrosion inhibition capabilities in different aqueous solutions, especially in alkaline conditions. Mass loss and electrochemical corrosion tests confirmed the efficiency of garlic peel in acidic, neutral, and basic solutions. SEM/EDS analysis revealed the reduction and alteration of corrosion products, while quantum simulation explained the superior performance of garlic peel in NaOH solution, attributing it to the generation of more active species.

Summary: In this study, the use of ionic liquids (ILs) as electrolytes in sodium-ion batteries (SIBs) is overviewed. While efforts have been made to find high-capacity and high cell potential materials, electrolyte safety is also crucial. The volatility of organic solvent-based electrolytes used in commercial systems poses a safety risk, making ILs a possible alternative. However, ILs have poor transport properties. Strategies to overcome these limitations and recent applications of ILs in SIBs are discussed, as well as the use of Na-IL mixtures in solid-state electrolytes.

Summary: This paper introduces and discusses the electrochemical mechanisms of sulfide minerals, and highlights the potential of using macro and microelectrodes to study the electrochemistry of sulfide minerals. A bibliometric search reveals that there is relatively little research in this area, with the majority of articles coming from Australia, South Africa, Turkey, and Canada. Electrochemical techniques can be used to investigate the surface properties of sulfide minerals and the efficiency of flotation processes.
