Silver nanoparticles prepared by chemical reduction-protection method, and their application in electrically conductive silver nanopaste

Mechanical properties of nano-silver joints as die attach materials

“…Generally, the Ag nanoparticles of sizes less than 20 nm are precipitated from Ag salts to form agglomerates with sizes ranging from 800 to 3500 nm [31]. Reducing agents like ascorbic acid [40,56], hydrazine monohydrate [57], sodium citrate [58] or sodium citrate dihydrate [59], polyvinylpyrollidone [50], ethylenediaminetetraacetic acid (EDTA) [60], sodium sulfite [61] and sodium borohydride [62] were added into Ag salts like nitrates, sulphates or chlorates or Ag-ammonia complexes [62]. The reducing reaction occurred in a polar solvent such as ethanol, methanol, acetonitrile or tetrahydrofurane [40].…”

Preparation and characterization of gelatin mediated silver nanoparticles by laser ablation

“…Recently, researchers have published various preparation methods of metal nanoparticles, including chemical and physical methods [1][2][3]. Among the physical methods, the photo-irradiation synthesis method offers many advantages, such as space-selective fabrication.…”

Enhanced chemocatalytic reduction of aromatic nitro compounds by biosynthesized gold nanoparticles

“…Chemical reduction method is the simplest process, widely used to obtain uniform, small size and highly dispersed nanoparticles [10]. But chemical reduction process for the syntheses of nanoparticles has a big drawback of requirements of hazardous chemicals and formation of toxic byproducts, making nanoparticles unsuitable for biological purposes [11][12][13].…”
