Lithium metal-based secondary batteries are very promising for next generation power battery due to their high energy density. However, lithium anodes suffer from poor electrochemical reversibility in organic electrolytes Li dendrites and instability of the solid electrolyte interphase. Recent research demonstrated that problem can be alleviated via tetraethoxysilane (TEOS) treated metal form a...

Grafting non-polar polymer chains on the surface of polar nanoparticles (e.g., silica) is an effective way to enhance particle/matrix interactions and thus promote their homogeneous dispersion within a matrix, which leads improved mechanical properties. Current grafting methods have not yet produced with well-defined polymers high density. Here, we employed anionic polymerization vacuum techniq...

Eccentric ellipsoidal variables (aka heartbeat stars) is a class of eccentric binaries in which proximity effects, tidal distortion due to time-dependent potential particular, lead measurable photometric variability close the periastron passage. The varying may also give rise tidally-excited oscillations (TEOs). TEOs play an important role dynamical evolution massive systems. Our study aimed at...

Highly porous organic–inorganic hybrids have been prepared from 3-(2,4-dinitrophenylamino)propyltriethoxysilane (DNPTES) and tetraethylorthosilicate (TEOS) by sol-gel method. The hybrids were characterized by FT-IR spectroscopy, UV–vis spectroscopy and elemental analysis, and their pore characteristics were studied by nitrogen sorption porosimetry. The applicability of the hybrids as adsorbent ...

In this work, rice straw fibers were modified using NaOH, KBM-403, and tetraethyl orthosilicate (TEOS), the changes in surface groups of before after modification analyzed by infrared testing. Straw/polylactic composite prepared hot pressing, effects modifiers used on properties these blends studied conducting mechanical thermal performance tests. The results showed that tensile strength fiber ...

We investigate the effects of amplitude modulation (AM) discharge method on growth nanoparticles and relation between plasma generation in tetraethylorthosilicate (TEOS)/O2/Ar plasma. The laser-light scattering (LLS) intensity, which is proportional to density sixth power size Rayleigh regime, decreases by 18% at an AM level 10% 60% 50%. On other hand, ArI emission roughly density, higher than ...
