Nanoparticles of cerium oxide with a narrow size distribution (±15%) are prepared by mixing nitrate solution an ammonium reagent. High-resolution transmission electron microscopy (TEM) indicates that over 99% the synthesized particles single crystals. TEM and photon absorption used to monitor particle size. The lattice parameter increases up 0.45% as decreases 6 nm, observed x-ray diffraction. Raman spectra also suggest particle-size effect concomitant expansion. expansion can be explained...
Nanocrystalline ceria particles have been prepared by mixing aqueous solutions of cerium nitrate and hexamethylenetetramine at room temperature. The smallest size nanoparticles synthesized is 2 nm. For each batch prepared, a narrow distribution found with standard deviation less than ±15%. A transmission electron microscopy (TEM) investigation shows that these are single crystals having either an octahedral shape eight {111} surfaces, or additional {200} surface-truncated shape. In-situ...
Lean electrolyte (small E/S ratio) is urgently needed to achieve high practical energy densities in Li-S batteries, but there a distinction between the cathode's absorbed (AE) which cathode-intrinsic and total added (E) depends on cell geometry. While pore volume sulfur cathodes affects AE/S performance, it shown here that morphology, size, connectivity, fill factor all matter. Compared conventional thermally dried usually render "open lakes" closed pores, freeze-dried compressed (FDS-C)...
Tuning the extraction performance of phenanthroline-derived ligands for Am 3+ by combining different functional groups.
Abstract For Li‐Se batteries, ether‐ and carbonate‐based electrolytes are commonly used. However, because of the “shuttle effect” highly dissoluble long‐chain lithium polyselenides (LPSes, Li 2 Se n , 4≤ ≤8) in ether sluggish one‐step solid‐solid conversion between carbonate electrolytes, a large amount porous carbon (>40 wt % electrode) is always needed for cathodes, which seriously counteracts advantage electrodes terms volumetric capacity. Herein an acetonitrile‐based electrolyte...
To synthesize a novel purple zirconia ceramic, Nd2O3 was introduced as colorant to improve the mechanical properties and color of ceramics. It found that causes obey different rules. With increases Nd2O3, ceramics is gradually deepened, corresponding negative influence on hardness. In this case, optimal comprehensive can be at 4 mol% Nd−2.5YSZ, which with an even, continuously adjustable positive high-temperature stability obtained used new type environmentally friendly colorful Based their...
Multinuclear U(VI) species may be dominant in aqueous solutions under environmental conditions, while the structures of multinuclear on mineral surfaces remain unclear. This work reports structural and bonding properties possible surface complexes three species,
The redistribution of intergranular amorphous films during creep deformation Si 3 N 4 has been studied by high‐resolution transmission electron microscopy. film thickness distribution a high‐purity material before and after was measured. A narrow range widths in the uncrept bimodal were observed. These observations provided convincing evidence occurrence viscous flow . Moreover, response predicted model good agreement with experimental data.
The compressive creep behavior of a high‐purity silicon nitride ceramic with and without the addition Ba was studied at 1400°C. Two distinct stages were observed during high‐temperature deformation both materials. Transmission electron microscopy (TEM) has been used to characterize intergranular glass film thickness. Statistical analysis number grain‐boundary films indicates that thickness is confined narrow range in as‐sintered However, mean greater Ba‐doped than undoped material. standard...
With the widespread use of wood-plastic composites, they are inevitably affected by aging during transportation and outdoor use. In this research, in order to improve resistance WPC, acrylate-styrene-acrylonitrile (ASA) was used as modifier (10 parts, 15 20 parts). The effects ASA modification on behavior eucalyptus/polyvinyl chloride (PVC) composites studied with simulated xenon lamp artificial conditions. Artificial caused physical mechanical properties deteriorate. After 960 h aging,...
