Abstract Melatonin is a multifunctional molecule found in all organisms that has been shown to play a crucial role in plant growth, development, and stress response. Plant melatonin is typically synthesized in organelles termed chloroplasts, and the mechanisms of its synthesis and metabolic pathways have been extensively studied. Melatonin serves a significant regulatory function in plant growth and development, influencing the morphological and physiological characteristics of plants by modulating biological processes. While studies on plant melatonin receptors are in their early stages compared to studies in animal receptors, the binding mechanism with melatonin is now recognized… More >

Abstract Ag/Al₂O₃ powders are highly effective catalytic materials utilized in the epoxidation of ethylene to produce ethylene oxide. One of the critical challenges in this catalytic process is the stability of nano-sized Ag particles, especially during high-temperature catalysis. However, this issue can be effectively addressed through in-situ reaction synthesis. To gain a deeper understanding of the underlying mechanisms, the phase transformation process and the thermodynamic mechanism of the oxidation reaction in the Ag/Al₂O₃ system have been investigated using first-principles thermodynamic calculations in conjunction with traditional thermodynamic data. These calculations, whose accuracy has been verified, provide valuable insights into… More >

Abstract The application of generative artificial intelligence (AI) is bringing about notable changes in anime creation. This paper surveys recent advancements and applications of diffusion and language models in anime generation, focusing on their demonstrated potential to enhance production efficiency through automation and personalization. Despite these benefits, it is crucial to acknowledge the substantial initial computational investments required for training and deploying these models. We conduct an in-depth survey of cutting-edge generative AI technologies, encompassing models such as Stable Diffusion and GPT, and appraise pivotal large-scale datasets alongside quantifiable evaluation metrics. Review of the surveyed literature… More >

Abstract The low efficiency of phytoextraction of lead (Pb) from agricultural fields poses a significant agricultural challenge. Organic chelating agents can influence Pb bioavailability in soil, affecting its uptake, transport, and toxicity in plants. This study aimed to assess the impact of citric acid (CA) and diethylenetriaminepentaacetic acid (DTPA) on chelate-assisted phytoextraction of Pb and its effect on growth and physiology of two cultivars (07001; 07002) of mung bean (Vigna radiata). The cultivars of mung bean were exposed to 60 mg·L⁻¹ lead chloride (PbCl₂) solution, with or without the addition of 300 mg·L⁻¹ CA or 500 mg·L⁻¹ DTPA, until… More >

Abstract Naturally occurring yellow leaf mutants are an important resource for studying pigment content and biosynthesis, as well as related gene expression. In our ongoing cultivation of Rehmannia chingii H. L. Li, we found an off-type yellow plant. The yellowing started with the new leaves and gradually spread downward until the entire plant exhibited a stable shade of yellow. We studied the differences in the chlorophyll and carotenoid content, carotenoid profile, and transcriptome of this yellow-leaf mutant (P2). Compared to the wild-type R. chingii plant (P1), P2 leaves had significantly lower chlorophyll and carotenoid content. LC-MS/MS analysis revealed More >

Abstract Grain filling is a critical determinant of yield and quality in rice. This study aims to clarify the association between grain photosynthesis and the filling rate of rice varieties with different grain weights, providing a theoretical foundation for optimizing grain-filling processes. Two rice varieties with similar growth duration but different grain weights were selected: a large-grain variety, Lingliangyou 268 (L268), and a small-grain variety, Ruiliangyou 1053 (R1053). Differences in grain filling, grain photosynthetic rate, and grain chlorophyll content were systematically examined during the filling stage. Results showed significant differences in grain-filling, grain photosynthetic rate, and… More >

Abstract Sunflower leaf photosynthesis strongly depends on the leaf position in the plant stem conditioning, which directly affects other physiological processes. Therefore, a study of the leaf’s physiological status regarding the leaf position in the stem was performed on sunflowers in the flowering stage. Eight differently positioned leaves were investigated, starting with the youngest leaf on the top of the stem to the leaves of the stem bottom, assigned as the oldest senescent leaves. According to chlorophyll fluorescence (ChlF) parameters connected to photosystem II (PSII) processes, significant changes in PSII functioning occurred only in the senescent… More >

Abstract The selection of carbon sources and the biosynthesis of polyhydroxybutyrate (PHB) by the Azotobacter vinelandii N-15 strain using renewable raw materials were investigated. Among the tested substrates (starch, sucrose, molasses, bran), molasses as the carbon source yielded the highest PHB production. The maximum polymer yield (26% of dry biomass) was achieved at a molasses concentration of 40 g/L. PHB formation was confirmed via thin-layer chromatography, gas chromatography and Fourier transform infrared spectroscopy. Composite films based on PHB, polylactic acid (PLA), and their blends were fabricated using the solvent casting. The biodegradation of these films was studied More > Graphic Abstract

Abstract In this study, 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate (ECC) and refined Camellia oleifera seed oil (RCOSO) obtained from saponification and acidified hydrolysis has been used as raw materials to perform ring-opening reactions for the preparation of cyclohexyl acrylate derivative (CAR). The structure of the synthesized product was characterized using infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance spectroscopy. CAR was employed as a plasticizer to produce modified polyvinyl chloride (PVC) films, dioctyl phthalate plasticizer (DOP) used in reference samples to investigate the influence of different plasticizer molecular structures on the properties of PVC films. Observation suggested that (1) CAR More >

Abstract PU, or polyurethane, features a repeating urethane group (-NH-COO-) in its molecular structure. Traditionally, PUs are synthesized from isocyanate and polyol compounds derived from fossil resources through polymerization reactions. The depletion of fossil fuels and the increasing climate problems call for the expansion of more renewable sources of chemicals, such as modern biomass. However, the conversion of biomass into chemicals is challenging due to the inherent molecular complexity of its composition. In recent years, advances in green chemistry have led researchers to focus on developing bio-based polyurethanes by sourcing polyols, isocyanates, and chain extender precursors More >
