Synthesis of well-dispersed ZnO nanomaterials by directly calcining zinc stearate

Preparation and properties of high‐performance recyclable ethylene propylene diene rubber

“…The EPDM‐g‐CCA/n‐Am samples had the characteristic peaks of EPDM (2915, 2848, 1465, 1435, and 1376 cm −1 ), the CO stretching peak at 1702 cm −1 , and additional amide (I) CO stretch peak at 1646 cm −1 and amide N–H stretching peak at 3570 cm −1 in the range of 3500∼3700 cm −1 indicating the occurrence of amidation reaction between carboxylic acid and amino acid. The EPDM‐g‐CCA/n‐Am/Io samples show the characteristic peaks of EPDM (2915, 2848, 1465, 1435, and 1376 cm −1 ), the CO stretch peak at 1702 cm −1 , amide (I) CO stretch peak at 1646 cm −1 , amide group peak at 3570 cm −1 , and zinc carboxylate salt peak at around 1538 cm −1 which originated from the CO stretching vibration of metal‐carboxylate salts, indicating the successfully formation of ionomers (EPDM‐g‐CCA/n‐Am/Io). Additionally, the intensity of carboxylate peak at 1538 cm −1 was found to decrease very slightly with increasing the carbon number of amino acids.…”

Mechanical Properties and Recyclability of Ionic Thermoplastic Rubber Based on Citraconated Ethylene Propylene Diene Monomer

“…(10) showed a characteristic peak for the stearate component at around 1539 cm -1 . 26 The IZnO(5)/ZnSt. ( 5)) sample had both two characteristic peaks for the Zn-ionomer and stearate component.…”

Antibacterial and photocatalytic activities of sonochemically prepared ZnO and Ag–ZnO

“…Preparation of Ag-ZnO nanoparticles by chemical [10], photochemical [11,12], coprecipitation [5,13], sol-gel [4], hydrothermal [14][15][16][17][18] or solvothermal [19], microwave [20], flame spray pyrolysis [21], electrospinning [22], and RF magnetron sputtering [23] methods and hybrid induction and laser heating technique [24] have been reported already. Although reports on synthesis of nanocrystalline ZnO are numerous, ZnO nanostructure continues to be of interest; it has been synthesized in the form of nanoparticles by chemical precipitation [25], nanowires by solution-phase reaction [26], nanoparticles, nanosheets, and hexagonal nanopyramids by direct calcination [27], and nanoparticles, nanowires, nanobelts, nanorods, prismatic nanorods, nanosheets, nanoflowers, nanospheres, and hollow spheres by hydrothermal method recently [28][29][30][31][32]. …”
