Argon gas was trapped at high pressure within hollow carbon tubes grown in vapor that have an outer diameter of between 20 and 150 nanometers. The forced into the by hot isostatically pressing (HIPing) material for 48 hours 650°C under argon 170 megapascals. Energy dispersive x-ray spectroscopy maps line scans across show is inside bore not tube walls. room temperature these estimated to be about 60 megapascals, which indicates equilibrium attained HIPing temperature. These findings...
The research presented here was conducted within the scope of an experiment investigating technical feasibility and environmental impacts tire combustion in a coal-fired power station. Previous work has shown that coal+tire blend rather than pure coal increased bulk emissions various elements (e.g., Zn, As, Sb, Pb). aim this study is to characterize chemical structural properties emitted single particles with dimensions <2.5 microm (PM2.5). This transmission electron microscope (TEM)-based...
Lanthanum zirconate has been prepared via a new chemical synthesis method by combining sol–gel processing and complex precipitation. The was carried out in aqueous solution under ambient conditions. synthesized powder possessed the pyrochlore superstructure upon calcination above 1200°C. A suite of characterization techniques, including FTIR , Raman, X ‐ray electron diffraction, TEM SEM nitrogen sorption were employed to investigate microstructural evolution bulk properties. Dense ceramics...
Transmission electron microscopy of a geopolymer phase, derived from metakaolin and alkaline silicate solutions having nominal Na/Al Si/Al molar ratios 1 2, respectively, showed it to be amorphous on the ∼1 nm scale after curing at 40°C. In samples containing 5 wt% Cs or Sr, inhabited whereas Sr was incorporated only partly, being preferentially partitioned crystalline SrCO 3 . Heating progressively dewater material had little effect overall structure for temperatures up 500°C. From...
The ability to decrease the electron/hole recombination rate, and band gap of titania allow photoactivity on irradiation with visible light is attracting more attention. Here, boron doping titania, deposition gold nanoparticles, along a meso-macroporous structure were obtained using facile agarose gel templating process combined sol–gel chemistry. Au/B/TiO2 nanocomposites characterized SEM, TEM, XRD, N2 gas sorption, diffuse UV–vis, photoluminescence, SIMS. photocatalytic activity was...
Pyrochlore‐structured lanthanide stannate ceramic ( Ln 2 Sn O 7 ) has been synthesized via a new complex precipitation method. A suite of characterization techniques, including FTIR , Raman, X‐ray, and electron diffraction as well nitrogen sorption were employed to investigate the structural evolution calcined powder. XRD selected area results confirm presence pyrochlore structure after calcination powder above 1200°C. TEM imaging shows fine crystallites gradually increased in size from...
A novel 1 V battery composed of Sn−LiCoPO4 using aqueous lithium hydroxide electrolyte is described. Reversible extraction and insertion from into the olivine-type LiCoPO4 reported. The electrochemical behavior was analyzed charge/discharge cycling cyclic voltammetry. exhibited voltages 1.3 V/0.8 versus Sn with a reversible capacity 80 mAh/g. structural morphological changes particles before after measurements were investigated by X-ray diffraction (XRD) transmission electron microscopy. XRD...

Polycrystalline synthetic samples of Y2Ti2−xSnxO7 with x = 0.4, 0.8, 1.2, and 1.6, together Nd2Zr2O7, Nd2Zr1.2Ti0.8O7, La1.6Y0.4Hf2O7, were irradiated in situ the intermediate voltage electron microscope (IVEM)-Tandem Facility at Argonne National Laboratory using 1.0 MeV Kr ions temperatures 50 to 650 K. Determination critical amorphization fluence (Fc) as a function temperature has revealed dramatic increase radiation tolerance increasing Sn content on pyrochlore B site. Nonlinear...
