Lead-free soldering for electronic industry is a segment of global trend toward lead-free environment. Although initiated in U.S. in early 1990’s, it advanced much more rapidly in Japan and Europe. This differentiation in Pb-free progress triggered great concerns of users of Pb-containing solders about maintaining business opportunity, therefore further expedites the advancement of Pb-free sold...

Antimicrobial nanobunches with different amounts of chitosan-capped Ag were prepared by continuous gas-liquid green route under ultrasound irradiation. Spark-produced aerosol Cu nanoparticles were directly injected into an ultrasound Ag(I)-chitosan reaction cell for efficient hydrosolization of the Cu particles and the subsequent incorporation of Ag and chitosan on Cu. Subsequently, electrospra...

The Ildeus mafic–ultramafic complex represents plutonic roots of a Triassic magmatic arc tectonically emplaced into the thickened uppermost crust beneath Mesozoic Stanovoy collided margin. cumulates host Ni-Co-Cu-Pt-Ag-Au sulfide-native metal-alloy mineralization produced through differentiation subduction-related primary mafic melt. This melt was sourced in metal-rich sub-arc mantle wedge hybr...

We measured the spontaneous decays of internally hot copper and silver dimer anions, ${\mathrm{Cu}}_{2}^{\ensuremath{-}}$ ${\mathrm{Ag}}_{2}^{\ensuremath{-}}$, stored in one two ion-beam storage rings Double Electrostatic Ion Ring Experiment (DESIREE) at Stockholm University. A coincidence detection technique was utilized enabling essentially background-free measurements ${\mathrm{Cu}}_{2}^{\en...

This study synthesizes hybrid of silver (Ag) and zinc oxide (ZnO) from their bulk salt to form Ag–ZnO nanocomposites for application as a humidity sensor. The Ag ZnO nanoparticles are synthesized using chemical reduction method, followed by co-mixing calcination yield the nanocomposite. characterized SEM, TEM, XRD, EDX establish morphological, structural elemental composition. Sensing measureme...

The nonlinear optical properties and the role of the surface-plasmon resonance (SPR) on optical limiting (OL) properties of Ag–Cu nanoclusters co-doped in SiO2 matrix prepared using the sol-gel technique with a Cu/Ag molar ratio of 1, 2 and 3, respectively, are presented. The studies were made using the second harmonic of high-power nanosecond and picosecond Nd:YAG lasers. These films show a se...

MAMMALIAN METALLOTHIONEIN IS REMARKABLE IN ITS METAL BINDING PROPERTIES: well-characterized species exist for metal to sulfur ratios of M(7)S(20), M(12)S(20), and M(18)S(20), where M = Cd(ll), Zn(ll), Hg(ll), Ag(I), Au(I), and Cu(I). Circular dichroism and luminescence spectra provide rich details of a complicated metal binding chemistry when metals are added directly to the metal free- or zinc...

The effects of five nanomaterials (multiwalled carbon nanotubes [MWCNTs], Ag, Cu, ZnO, Si) and their corresponding bulk counterparts on seed germination, root elongation, and biomass of Cucurbita pepo (zucchini) were investigated. The plants were grown in hydroponic solutions amended with nanoparticles or bulk material suspensions at 1000 mg/L. Seed germination was unaffected by any of the trea...

Adsorption of carbonmonoxide on the silver ion-exchanged Ag-ZSM-5 zeolite has been studied using both quantum cluster and embedded cluster at the models B3LYP/6-31G(d,p) level of theory. The Ag...Oz distance in Ag-ZSM-5 complexes is predicted to be 2.26 Å for the quantum cluster and 2.32 Å for the embedded cluster, the latter is in agreement with the experimental value of 2.30 + 0.03 Å. The opt...

Silver crystallite-graphene oxide (Ag-Nps/GO) composites are widely used for various applications and an attractive material next-generation nano-electronic devices, we demonstrate their use in humidity sensors. crystallite (Ag-Nps) is prepared through a single step by reduction method at room temperature. The resulting pure phase as confirmed X-ray diffraction (XRD) without any traces of oxide...
