Zincite (ZnO) nanoparticles are prepared by adopting reflux assisted co-precipitation method. Prepared product is subjected to different instrumental techniques to investigate its morphology and lattice structure. Rietveld refinements are performed on XRD results and values of various lattice parameters are calculated and structural model of ZnO is predicted. The morphology of the product is analyzed with the help of scanning and transmission electron microscopies (SEM and TEM). The size of prepared nanoparticles is in the range of 80–100 nm where as some larger particles having irregular morphology with size up to 1 μm are also observed in the product. Prepared product is also used as fuel additive and its effect on different fuel parameters is studied. The combustion characteristics (flash and fire point) and physical characteristics (cloud and pour point, kinematic viscosity and specific gravity) of fuel are studied in the presence of 10, 15 and 20 ppm dosage of additive. ZnO is used as nanoadditive for enhancing concrete durability. Concrete pellets are formed with different dosage (0, 0.1, 0.5, 1.5 w/w%) of nanoadditive. Ratio of cement, sand and nanoadditive is kept as 33:66:1 respectively in all concrete samples with constant amount of water. Effect of nanoadditve is studied on different properties of cement such as aging, porosity, compressive strength, specific heat, thermal conductivity and thermal diffusivity. ZnO nanoadditive is found to be effective in modulating both mechanical and thermal properties of concrete samples.

锌酸锌纳米颗粒作为燃料添加剂的结构表征,合成与应用

采用回流辅助共沉淀法制备了ZnO(ZnO)纳米粒子。制备的产品要经受各种仪器技术的研究,以研究其形态和晶格结构。对XRD结果进行Rietveld精修,并计算各种晶格参数的值,并预测ZnO的结构模型。借助扫描和透射电子显微镜(SEM和TEM)分析产品的形态。制备的纳米颗粒的尺寸在80–100 nm范围内,其中在产品中还观察到一些较大的具有不规则形态的颗粒,尺寸最大为1μm。制成品还可用作燃料添加剂,并研究了其对不同燃料参数的影响。在添加剂的添加量为10、15和20 ppm的情况下,研究了燃料的燃烧特性(闪点和着火点)和物理特性(浊点和倾点,运动粘度和比重)。ZnO用作纳米添加剂以增强混凝土的耐久性。形成具有不同剂量(0、0.1、0.5、1.5 w / w%)的纳米添加剂的混凝土颗粒。在水量恒定的所有混凝土样品中,水泥,沙子和纳米添加剂的比例分别保持为33:66:1。研究了纳米添加剂对水泥不同性能的影响,例如老化,孔隙率,抗压强度,比热,导热系数和热扩散系数。发现ZnO纳米添加剂可有效地调节混凝土样品的机械性能和热性能。在添加剂的添加量为10、15和20 ppm的情况下研究了燃料的运动粘度和比重)。ZnO用作纳米添加剂以增强混凝土的耐久性。形成具有不同剂量(0、0.1、0.5、1.5 w / w%)的纳米添加剂的混凝土颗粒。在水量恒定的所有混凝土样品中,水泥,沙子和纳米添加剂的比例分别保持为33:66:1。研究了纳米添加剂对水泥不同性能的影响,例如老化,孔隙率,抗压强度,比热,导热系数和热扩散系数。发现ZnO纳米添加剂可有效地调节混凝土样品的机械性能和热性能。在添加剂的添加量为10、15和20 ppm的情况下研究了燃料的运动粘度和比重)。ZnO用作纳米添加剂以增强混凝土的耐久性。形成具有不同剂量(0、0.1、0.5、1.5 w / w%)的纳米添加剂的混凝土颗粒。在水量恒定的所有混凝土样品中,水泥,沙子和纳米添加剂的比例分别保持为33:66:1。研究了纳米添加剂对水泥不同性能的影响,例如老化,孔隙率,抗压强度,比热,导热系数和热扩散系数。发现ZnO纳米添加剂可有效地调节混凝土样品的机械性能和热性能。形成具有不同剂量(0、0.1、0.5、1.5 w / w%)的纳米添加剂的混凝土颗粒。在水量恒定的所有混凝土样品中,水泥,沙子和纳米添加剂的比例分别保持为33:66:1。研究了纳米添加剂对水泥不同性能的影响,例如老化,孔隙率,抗压强度,比热,导热系数和热扩散系数。发现ZnO纳米添加剂可有效地调节混凝土样品的机械性能和热性能。形成具有不同剂量(0、0.1、0.5、1.5 w / w%)的纳米添加剂的混凝土颗粒。在含水量恒定的所有混凝土样品中,水泥,沙子和纳米添加剂的比例分别保持为33:66:1。研究了纳米添加剂对水泥不同性能的影响,例如老化,孔隙率,抗压强度,比热,导热系数和热扩散系数。发现ZnO纳米添加剂可有效地调节混凝土样品的机械性能和热性能。
