Electron Compensation Effect Suppressed Silver Ion Release and Contributed Safety of Au@Ag Core-Shell Nanoparticles
Au@Ag core-shell electron compensation safety biomedical application
2023/6/21
Silver nanoparticles (Ag NPs) have promising plasmonic properties, however, they are rarely used in biomedical applications because of their potent toxicity. Herein, an electron compensation effect fr...
Comparative Study of Gacun and Youre Silver–Lead–Zinc–Copper Deposits in Sichuan, SW China, and their Mineralization Significance
ore-bearing horizon structure of ore-bearing belt VMS deposit Gacun–Youre ore district
2018/4/10
The large Gacun silver–lead–zinc–copper deposit in Sichuan Province is one of the largest volcanogenic massive sulfide (VMS) deposits in China. The deposit consists of western and central ore bodies, ...

The Woods Hole Oceanographic Institution Women's Committee initiated the Woman Pioneer in Oceanography Award in 1994 as part of a Women's History Month celebration. Past awardees have included Mary Se...
Environmentally Friendly Lignin Nanoparticle ‘Greens’ Silver Nanobullet to Battle Bacteria
Environmentally Friendly Lignin Nanoparticle Greens Silver Nanobullet Battle Bacteria
2015/8/4
Silver nanoparticles have antibacterial properties, but their use has been a cause for concern because they persist in the environment. Here, we show that lignin nanoparticles infused with silver ions...
Nanfang Yu, assistant professor of applied physics at Columbia Engineering, and colleagues from the University of Zürich and the University of Washington, have discovered two key strategies that enabl...
Electric dipole-free interaction of visible light with silver metadimers
Electric dipole-free interaction visible light silver metadimers Optics
2012/4/19
In subwavelength-sized particles, light-induced multipole moments of orders higher than the electric dipole are usually negligibly small, which allows for the light-matter interaction to be accurately...
Thermochromism of Silver Oxide for Optical Switching Layers in Volumetric Optical Disks
phase change volumetric optical disk dual layer optical disk optical switching layer thermo-chromatic material thermochromism silver oxide
2011/11/28
For reading and writing on a lower targeted recording layer ofvolumetric optical disks, transmitted laser power is decreased by absorption and reflection ofthe upper layers. Thus, a layer ofthermo-chr...
We report the fabrication of nanoparticle silver oxide thin films by rf magnetron sputtering and characterization of their nonlinear optical properties. The chemical decomposition and reversibility of...

Through a simple room-temperature photoreduction process, this letter conformally replicates 3D submicrometer structures of wing scales from two butterfly species into Ag to generate practical surface...
Ultrathin optical switch based on a liquid crystal/silver nanoparticles mixture as a tunable indefinite medium
Ultrathin optical switch liquid crystal silver nanoparticles tunable indefinite medium
2011/8/2
Abstract: We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts of differ...
