Moringa oleifera, a versatile plant, has been traditionally used to treat various ailments and is gaining scientific attention due to its potential as a medicine. Native to the Indian subcontinent, it is widely grown in tropical and subtropical regions, thriving in Asia, Africa, and South America, especially in arid climates. This study explores the antioxidant potential of Moringa oleifera leaf extract (MOLE), employing a comprehensive screening approach with various solvents to identify the most effective extraction method. Initial experiments assessed antioxidant efficacy and yield using distilled water (D.W.), 95% ethanol, and 95% methanol. Among these, 95% ethanol extract demonstrated superior antioxidant activity, confirmed through assays such as 2,2-diphenyl-1-14 picrylhydrazyl (DPPH) radical scavenging assay, total polyphenol content analysis, and reducing power assay. In addition, with the 95% ethanol MOLE, a higher extraction efficiency was yielded compared to other solvents, making it the most effective for large-scale preparation. HPLC analysis revealed the presence of key bioactive compounds, including ellagic acid, rutin, Q-3-O, quercetin, and kaempferol. Results revealed that MOLE, prepared using 95% ethanol, exhibited remarkable antioxidant properties, attributed to its rich polyphenolic content. This research underscores the therapeutic potential of MOLE as a natural antioxidant source and highlights the importance of solvent optimization in phytochemical extractions.

Seeds of some barberry species have embryo with physiological dormancy that requires a cold stratification for germination. Berberis amurensis Rupr. is a native species of Japan, Korea, the Russian far east, and parts of China. This specific plant is important for its edible fruits and rhizomes with high medicine value. This study aimed to determine the effect of stratification on germination and physiological change of B. amurensis. Seeds were placed on sterilized sand medium moistened with distilled water in 9 cm diameter petri dishes and stored at 4 and 25˚C for 0, 15, 30, 45 and 60 days. Each treatment had 40 seeds per replica, and three repetitions per treatment. Immediately after stratification, total phenolics contents (TPC) was analyzed and seeds incubated at 15/6˚C for 12 weeks. Warm stratification had a significant effect on seed forcing for germination than cold stratification treatment. At 25˚C for 60 days, stratified seed showed highest germination percentage (25.7±4.3%) and germination started in 14 days of the stored period. Whereas TPC was significantly decreased with increasing stored period. Contrastively, cold stratification had no effect on the germination ability. In the same way germination percentage of non-stratified seeds were also zero. The results confirmed that B. amurensis seeds were in a dormant state and warm stratification increased the germination ability by breaking of dormancy.

In this study, ester co-solvents and fluoroethylene carbonate (FEC) were used as low-temperature electrolyte additives to improve the formation of the solid electrolyte interface (SEI) on graphite anodes in lithium-ion batteries (LIBs). Four ester co-solvents, namely methyl acetate (MA), ethyl acetate, methyl propionate, and ethyl propionate, were mixed with 1.0 M LiPF6 ethylene carbonate:diethyl carbonate:dimethyl carbonate (1:1:1 by vol%) as the base electrolyte (BE). Different concentrations were used to compare the electrochemical performance of the LiCoO2/ graphite full cells. Among various ester co-solvents, the cell employing BE mixed with 30 vol% MA (BE/MA30) achieved the highest discharge capacity at − 20 °C. In contrast, mixing esters with low-molecular-weight degraded the cell performance owing to the unstable SEI formation on the graphite anodes. Therefore, FEC was added to BE/MA30 (BE/MA30-FEC5) to form a stable SEI layer on the graphite anode surface. The LiCoO2/ graphite cell using BE/MA30-FEC5 exhibited an excellent capacity of 127.3 mAh g− 1 at − 20 °C with a capacity retention of 80.6% after 100 cycles owing to the synergistic effect of MA and formation of a stable and uniform inorganic SEI layer by FEC decomposition reaction. The low-temperature electrolyte designed in this study may provide new guidelines for resolving low-temperature issues related to LIBs, graphite anodes, and SEI layers.

Electrical and thermal transport properties of a polycrystalline carrier-doped wide-gap semiconductor LaCu1-δ S0.5Se0.5O (δ = 0.01), in which the CuCh (Ch = S, Se) layer works as conducting layer, were measured at temperatures 473~673 K. The presence of δ = 0.01 copper defects dramatically reduces the electrical resistivity (ρ) to approximately one part per million compared to that of δ = 0 at room temperature. The polycrystalline δ = 0.01 sample exhibited ρ of 1.3 × 10-3 Ωm, thermal conductivity of 6.0 Wm-1 K-1, and Seebeck coefficient (S) of 87 μVK-1 at 673 K. The maximum value of the dimensionless figure of merit (ZT) of the δ = 0.01 sample was calculated to be 6.4 × 10-4 at T = 673 K. The ZT value is far smaller than a ZT ~ 0.01 measured for a nominal LaCuSeO sample. The smaller ZT is mainly due to the small S measured for LaCu1-δS0.5Se0.5O (δ = 0.01). According to the Debye model, above 300 K phonon thermal conductivity in a pure lattice is inversely proportional to T, while thermal conductivity of the δ = 0.01 sample increases with increasing T.

This review examines the microstructural and mechanical properties of a Ti-6Al-4V alloy produced by wrought processing and powder metallurgy (PM), specifically laser powder bed fusion (LPBF) and hot isostatic pressing. Wrought methods, such as forging and rolling, create equiaxed alpha (α) and beta (β) grain structures with balanced properties, which are ideal for fatigue resistance. In contrast, PM methods, particularly LPBF, often yield a martensitic α′ structure with high microhardness, enabling complex geometries but requiring post-processing to improve its properties and reduce stress. The study evaluated the effects of processing parameters on grain size, phase distribution, and material characteristics, guiding the choice of fabrication techniques for optimizing Ti-6Al-4V performance in aerospace, biomedical, and automotive applications. The analysis emphasizes tailored processing to meet advanced engineering demands.

A new variety of Alfalfa (Medicago sativa L.), named 'Alfaking' was developed between 2015 and 2023 at the Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, Cheonan, Republic of Korea. The variety was produced through artificial hybridization, with ‘Paravivo’ serving as the maternal line and ‘WL514’ as the paternal line. ‘Alfaking’ underwent field tests across four regions (Cheonan, Pyeongchang, Jeongeup, and Jinju) to evaluate its agronomic characteristics and forage production over two years (2022-2023). The dry matter yield of ‘Alfaking’ reached 22,516 kg/ha, which is 11% higher than the control variety, ‘Vernal.’ ‘Alfaking’ exhibited 2.1% higher crude protein content than ‘Vernal’ in forage nutritive value. The development of this new alfalfa variety, which exhibits excellent adaptability to challenging environmental conditions, is expected to enhance forage cultivation and productivity in Korea.

Background: Porcine embryonic development is widely utilized in the medical industry. However, the blastocyst development rate in vitro is lower compared to in vivo . To address this issue, various supplements are employed. Extracellular vesicles (EVs) play the role of communicators that carry many bioactive cargoes. Additionally, the contents of EVs can vary on the estrous cycle. Methods: We compared the effects of adding EVs derived from porcine uterine fluid (UF), categorized as non-EV (G1), EVs in estrus (G2) and EVs in diestrus (G3). After in vitro culture (IVC) was performed in three different groups, cleavage rate and blastocyst development rate were examined. In addition, glutathione (GSH) and reactive oxygen species (ROS) levels were measured 2 days after activation to assess oxidative stress. Results: Using NTA and cryo-TEM, we confirmed the presence of EVs with sizes ranging from 30 nm to 200 nm, that the particles were suitable for analysis for analysis. In IVC data, the highest cleavage rate was observed in G2, which was significantly different from G1 but not significantly different from the next highest, G3. Similarly, the highest blastocyst development rate was observed in G2, which was significantly different from G1 but not significantly different from the next highest, G3. Conclusions: These results indicate that estrus derived EVs contain biofactors beneficial for early blastocyst development, including GSH which protects the blastocyst from oxidative stress. Additionally, although diestrus-derived EVs are expected to have some effect on blastocyst development, it appeared to be less effective than estrus-derived EVs.

Meristem culture (MC) is a technique for producing virus-free garlic plants with high vigor and productivity. We assessed the changes in the agronomic traits of “Namdo” garlic over several generations after the cultivation of MC-induced bulbils. We examined the plant height, leaf sheath length and diameter, leaf number, bulb weight and diameter, clove number, and bulb size distribution. Compared with that of the control, bulb weights of the first-generation bulbils cultivated for three and two years and the second-generation bulbils cultivated for one year increased by 8.7–27.2, 13.9–30.4, and 36.6–46.9%, respectively. In three and two-year cultivation of the firstgeneration bulbils and one-year cultivation of the second-generation bulbils, the proportions of extra-large-sized bulb weight in meristem-cultured plants were 16.2–38.6, 24.0–35.8, and 27.1–51.1%, respectively, whereas that of the control was 7.6%. Thus, the first-generation bulbils can be cultivated for three years to renew the seed bulbs while maintaining productivity.

Despite enormous popularity of graphene oxide (GO) several open questions remain regarding the structure and properties of this material. One of those questions is the role of a graphite precursor on the properties of GO product. In this study, we investigate the oxidation process and the structure of GO products, made from the four different graphite precursors: synthetic graphite, two natural flaky graphites, and expanded graphite. The highest rate of the oxidation reaction was registered for the small particle size synthetic graphite. Thermal expansion of natural flaky graphite did not significantly affect the rate of the reaction. The nature of the graphite precursor does not notably affect the chemical composition of the synthesized GO products. However, it affects stability of respective aqueous dispersions. The solutions of the three GO samples, prepared from the natural graphite sources demonstrate excellent stability due to complete exfoliation of GO to single-atomic-layer sheets. GO from synthetic graphite forms unstable dispersions due to the presence of numerous multi-layered particles. This, in turn, is explained by the presence of not fully graphitized, amorphous inclusions in synthetic graphite. Our observations suggest that synthetic graphite should not be used as GO precursor when the ability to completely exfoliate and the stability of dispersions are critical for intended applications.

수염풍뎅이(Polyphylla laticollis manchurica)는 과거에는 흔히 발견되었으나, 1970년대 이후 한반도 내 개체수 가 급격히 감소하여 2005년 환경부에 의해 멸종위기 야생생물 Ⅰ급으로 지정되었다. 또한 해당종의 분자생물학적 연구는 멸종위기종이라는 특성으로 인해 제한적으로 진행되었다. 그로 인해 NCBI 등 공공 데이터베이스에서 제공되는 서열정보들 또한 부족한 실정이다. 이 연구는 이러한 한계를 극복하고 수염풍뎅이의 유전적 특성을 규명하기 위해 생물정보학적 기술을 활용하여 전사체 분석을 진행하였다.
