Summary: This study investigates the reductant engineering to grow high-quality tin perovskite single crystals under ambient conditions. Oxalic acid is proved to be an ideal reductant and sacrificial agent for protecting Sn2+ ions in methanol. By constructing a single crystal heterojunction, the FPEA2SnI4 single crystal exhibits low trap density perovskite surface and improved X-ray sensitivity. This research is of great importance in addressing the challenges of tin perovskite single crystal growth under ambient conditions.

Summary: Oxalate is a divalent organic anion that is commonly found in plant-derived foods and can also be produced by humans and other mammals. It is known to be a major component of kidney stones and can cause an inflammatory response. Oxalate is used in various industries but can also be problematic, depending on the context. Efficient methods for quantifying oxalate have been developed over the years, including electrochemical detection, mass spectrometry, and indicator-based methods. This review explores the strengths and limitations of each method, providing researchers with a reference for choosing the most suitable approach.

Summary: Pretreatment with aqueous protic ionic liquid (PIL)-ethanolamine bis(oxalate) combined with ultrasonic disintegration was used to produce cellulose nanofibrils (CNFs) from pulp fibers. The optimization of pretreatment parameters was conducted using the response surface methodology and resulted in a maximum CNF yield of 86.2%. The produced CNFs exhibited high crystalline index and thermal stability, making them suitable for low-cost and clean production.

Summary: Zinc and manganese spinel cobaltites were prepared by hydrothermal method using oxalic acid as precipitant. The structural, microstructural, and magnetic and microwave absorption properties were analyzed. The ZnCo2O4 nanoparticles were arranged as lamellar-like morphology, while the MnCo2O4 powders were composed of the large octahedral particles. The ZnCo2O4 powders showed higher magnetization and better microwave absorption performances.

Summary: In this study, reduced graphene oxide (rGO) was prepared via hydrothermal treatment in the presence of montmorillonite (Mt), which helped prevent the reduction of graphene oxide by oxalic acid and reduce the irreversible restacking of rGO sheets. The resulting rGO electrode exhibited high specific capacitance and excellent cycle stability, demonstrating the potential of utilizing multi-role Mt to control the effects of oxalic acid on graphene oxide.

Summary: This study investigates the effects of different amendments and low-molecular-weight organic acids on the release of potentially toxic elements (PTEs) from soils. The highest release of PTEs was observed with citric acid, followed by oxalic and malic acids. The addition of poultry manure was found to be the most environmentally friendly amendment. The results highlight the importance of considering cadmium (Cd) in order to prevent environmental pollution.

Summary: This study evaluated the potential efficacy of the natural compound oxalic acid (OA) as an inhibitory agent against the invasion of SARS-CoV-2 variants Delta and Omicron. OA significantly blocked the binding of Delta B.1.617.2 and Omicron B.1.1.529 receptor binding domains (RBDs) to ACE2 in vitro and inhibited the entry of pseudoviruses of these variants into ACE2-expressing cells. Surface plasmon resonance analysis confirmed the direct bindings of OA to RBDs and ACE2. Molecular docking predicted the binding sites on the RBD-ACE2 complex, showing similar binding abilities to both Delta and Omicron variants. In conclusion, OA is a promising small-molecule compound for targeting SARS-CoV-2 variants.

Summary: Oxalic acid, a low molecular weight organic acid, plays important roles in plant growth and development, as well as response to stresses. While its metabolism is well-studied in microorganisms, fungi, and animals, it remains less understood in plants. Excessive accumulation of oxalic acid is harmful to plants, thus precise control of its level is necessary. This review summarizes the metabolism, function, and regulation of oxalic acid in plants and discusses solutions to manipulate its metabolism for regulating plant responses.

Summary: The effect of mannitol was studied on the separation of poplar using mannitol-assisted oxalic acid pretreatment. The optimized conditions for separation efficiency were identified. Hemicellulose separation was achieved at 79.08%, while the separation of cellulose and lignin decreased. Smooth fiber surfaces and changes in lignin structure were observed, indicating lignin prevention. The environmentally friendly separation of hemicellulose provides a practical approach for resolving lignin problems during organic acid pretreatment.

Summary: Form II paracetamol, with improved compressibility, has attracted researchers' attention. This study focused on the selective polymorphic formation of paracetamol using cooling crystallization with four types of additives. The results showed that the addition of more additives increased the probability of forming Form II paracetamol. By seeding the paracetamol solution with Form II paracetamol and fumaric acid crystals, Form II paracetamol could be induced, while the other three carboxylic acids were not effective. The study also discovered a new solution complex of paracetamol-oxalic acid, responsible for the selective nucleation of Form II paracetamol in the oxalic acid solution. Additionally, the range of supersaturation for nucleating Form II paracetamol was extended with the assistance of oxalic acid or fumaric acid. In large-scale crystallization, Form II paracetamol was successfully produced using continuous crystallization in a fumaric acid aqueous solution.
