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...

Geologic imaging technique measures strength of Earth’s outer shell
Geologic imaging technique measures strength Earth’s outer shell
2016/10/10
An advanced imaging technique used to map Earth’s outer shell also can provide a measure of strength, finding weak spots and magma upwellings that could point to volcanic or earthquake activity, accor...
Shell analysis of elliptical guard cells in higher plants: a review
Shell analysis elliptical guard cells higher plants
2015/8/27
This presentation reviews finite element shell analyses (linear and nonlinear, isotropic and anisotropic) of microscopic stomata modeled as doubly-elliptic toroidal shells. Stomata are the regulating ...
The environments of supernova explosions are often inhomogeneous, and there may be jumps in their density structure. We have developed a semianalytic model under the thin-shell approximation for super...
DISTANCE DETERMINATION TO THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3 AND THE SEARCH FOR ITS SUPERNOVA REMNANT SHELL
supernova remnants molecules radio continuum
2014/12/23
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
Microarray Analysis of Genes Involved with Shell Strength in Layer Shell Gland at the Early Stage of Active Calcification
Chicken Microarray Differentially Expressed Genes Eggshell Strength
2016/5/11
The objective of this study was to get a comprehensive understanding of how genes in chicken shell gland modulate eggshell strength at the early stage of active calcification. Four 32-week old of pure...
Dielectronic recombination of W^20+ (4d^10 4f^8): addressing the half-open f-shell
Dielectronic recombination half-open f-shell Atomic Physics
2012/4/20
A recent measurement of the dielectronic recombination (DR) of W^20+ [Schippers et al Phys. Rev. A83, 012711 (2011)] found an exceptionally large contribution from near threshold resonances (<1eV). Th...
Hypervelocity Impact of the Icy Droplet on Al Shell at Nanoscale: A Molecular Dynamics Probe
hypervelocity impact molecular dynamics debris cloud icy droplet
2012/9/24
Large-scale molecular dynamics (MD) simulations are conducted to investigate the hypervelocity impact of the icy droplet on spacecraft Al shell at the atom ic level. The velocity of the droplet is se...
The charged dust solution of Ruban -- matching to Reissner--Nordström and shell crossings
shell crossings even half cycle oscillation minimal size
2011/10/14
The maximally extended Reissner--Nordstr\"om (RN) manifold with $e^2 < m^2$ begs for attaching a material source to it that would preserve the infinite chain of asymptotically flat regions and evolve ...
Synthesis and Characterization of Silylated Kaolinite/Silica Core–Shell Nanoparticles
Core-Shell Kaolinite Modification Silane Silica
2011/11/14
Studies were conducted on the production of silane modified kaolinite/silica core-shell nanoparticles (SMKS). The SMKS nanoparticles were prepared via the sol–gel technique using tetraethyl oxysilane ...
