TiO2 thin films and Ag/TiO2 nanoparticles were prepared by CVD and plasma bombardment method. XRD results showed the presence of Ag nanoparticles in TiO2 matrix. SEM image confirmed formation of Ag nanoparticles. XPS analysis was utilized to study the chemical state of the Ag/TiO2 nanostructure. Statistical surface analysis revealed that since there i...

Aerodynamically focused nanoparticle (AFN) printing was demonstrated for direct patterning of the solvent-free and inorganic nanoparticles. The fast excitation-purge control technique was proposed and investigated by examining the aerodynamic focusing of nanoparticles and their time-scale, with the analytical and experimental approaches. A series of direct patterning examples were demonstrated ...

Highly uniform and dense, hexagonal noble metal nanoparticle arrays were achieved on large-area transparent glass substrates via scalable, parallel processing of block copolymer lithography. Exploring their localized surface plasmon resonance (LSPR) characteristics revealed that the Ag nanoparticle array displayed a UV-vis absorbance spectrum sufficiently narrow and intense for biosensing appli...

The adsorption of three- and four-atom Ag and Pd clusters on the alpha-Al(2)O(3) (0001) surface is explored with density functional theory. Within each adsorbed cluster, two different cluster-surface interactions are present. We find that clusters simultaneously form both ionic bonds with surface oxygen and intermetallic bonds with surface aluminum. The simultaneous formation of disparate elect...

The paper demonstrated the synthesis of Ag-Ag2O/g-C3N4 nanoparticles via a simple liquid phase synthesis path and a facile calcination method. The synthesized Ag-Ag2O/g-C3N4 composites were well characterized by various analytical techniques, such as X-ray diffraction, Fourier transform infrared (FT-IR), X-ray photoemission spectroscopy, transmission electron microscopy, scanning electron micro...

The potential effects of extracellular polymeric substances (EPS) on the behavior and toxicity silver nanoparticle (Ag-NPs) sulfide (Ag2S-NPs) remains ambiguous. interaction EPS from Bacillus subtilis with Ag2S-NPs, metallic Ag-NPs, or ionic Ag, associated plant safety had been examined in this study. biological impacts Ag-NPs Ag2S-NPs were Ag form-dependent highly influenced by microbial EPS. ...

The natural convection heat transfer of horizontal rectangle enclosures with different aspect ratios (A = 2:1 and A = 4:1) filled with Ag-Ga nanofluid (different nanoparticle volume fractions φ = 0.01, φ = 0.03, φ = 0.05 and radiuses r = 20 nm, r = 40 nm, r = 80 nm) at different Rayleigh numbers (Ra = 1 × 103 and Ra = 1 × 105) is investigated by a two-phase lattice Boltzmann model. It is found ...
