在本文中，绿色和简便合成含硫和氮的共掺杂的碳纳米球（CNS）从提取物制备玫瑰茄L请直接水热法。最后，硫碳纳米球（CNS）用作吸附剂，以除去铅⁺²离子从由于来自CN的和N-的CN S-CN的高表面积的水溶液。将合成的纳米球是由傅立叶检查变换红外（FTIR）光谱法，X射线衍射（XRD），场发射扫描电子显微镜，透射电子显微镜（TEM），和氮吸附 - 脱附等温线。The results show spherical shapes have a particle size of up to 65 nm with a high surface area capable of absorbing lead ions efficiently. Additionally, the factors affecting the process of adsorption that include equilibrium time, temperature, pH solution, ionic intensity, and adsorbent dose were studied. The equilibrium removal efficiency was studied employing Langmuir, Freundlich, and Temkin isotherm forms. The kinetic data were analyzed with two different kinetic models, and both apply to the adsorption process depending on the values of correlation coefficients. The thermodynamic parameters including Gibbs free energy (ΔG度），标准焓变（ΔH度），和标准熵变化（Δ小号°）分别计算吸附过程。

粉煤灰，火电厂的废产物，是用作聚合物填充物的良好选择之一，尤其是在阻燃剂。飞灰是用于复合材料中，代替常规的阻燃添加剂的使用，例如卤代有机化合物对环境友好的阻燃添加剂，从而促进环境安全。在这项研究中，飞灰用硬脂酸改性，以提高在聚合物界面和增加的相容性粘附性。飞灰在本研究中，以合成飞灰 - 环氧复合材料中使用的各种体积（5，10，和20重量％的飞灰）进行了研究。The results show that the tensile strength, flexural strength, compressive strength, and impact strength of these synthetic materials increase when fly ash is modified to the surface, compressive strength: 197.87 MPa, flexural strength: 75.20 MPa, impact resistance: 5.77 KJ/m², and tensile strength: 47.89 MPa. Especially, the fire retardant properties are improved at a high level, with a modified 20% fly ash content: the burning rate of 16.78 mm/min, minimum oxygen index of 23.2%, and meet the fire protection standard according to UL 94HB with a burning rate of 8.09 mm/min. Scanning electron microscopy (SEM) and infrared spectroscopy were used to analyze the morphological structure of fly ash after being modified and chemically bonded with epoxy resin background.

这项研究调查了细菌的潜力单胞菌UCP 1601 to produce a new biomolecule with emulsifying properties by determining the hemolytic activity, obtaining a halo of 9 mm in blood agar. Fermentations were carried out in saline mineral medium supplemented with 10% waste soybean oil (WSO) and different concentrations of glucose, peptone, ZnCl₂和硫酸镁₄，根据2⁴全因子设计。结果表明，最好的结果是在4％葡萄糖，1％蛋白胨，2.72％的ZnCl组成条件6（介质获得₂和2.46％硫酸镁₄），具有82.74％的优异的高乳化指数，使用烧机油。所产生的生物分子的乳化性是由78.57，54.07乳化指数和58.62％，使用大豆，玉米，和柴油，分别与在pH值，温度的不同值的稳定性，和NaCl浓度证实。The yield of the produced bioemulsifier was 2.8 g/L, presenting an anionic character and polymeric nature (37.6% lipids, 28.2% proteins, and 14.7% carbohydrates), confirmed by FTIR. The new bioemulsifier demonstrated promising potential for bioremediation of hydrophobic contaminants in the environment, since it had the ability to reduce the viscosity of WSO and burned motor oil, as well as excellent dispersion capacity of the burned motor oil in water (69.94 cm²的油位移区），以及从沙土此石油衍生的71.7％。

在本文中，葡糖胺是由五个蘑菇酸水解产生。葡糖胺产量进行了研究，得到的最佳条件如下：酸型，硫酸;acid concentration, 6 M; ratio of raw material to acid volume, 1 : 10; hydrolysis temperature, 100°C; and time, 6 h. Under these conditions, the glucosamine conversion from chitin content reached up to 92%. The results of hydrolysis kinetics indicated that hydrolysis of five mushrooms to glucosamine followed zero-order kinetics. Moreover, the relatively low activation energy for hydrolysis of straw mushroom (18.31 kJ/mol) and the highest glucosamine yield (56.8132 ± 3.5748 mg/g DM, 0.9824 g/g chitin) indicated that hydrolysis of straw mushroom was energy-saving. Thus, sulfuric acid hydrolysis of straw mushroom for glucosamine production should be considered as an efficient process for the future industrial application. However, further study is needed for glucosamine purification.
