Li+ Intercalation into TiO2-B nanowires is reported up to a composition of Li0.91TiO2-B (specific charge capacity: 305 mA h g–1) and with superior rate capability nanoparticulate anatase bulk (see Figure). The combination high capacity for intercalation, capability, potential ∼1.6 V, renders the intercalated interesting as anodes rechargeable lithium batteries negative electrodes supercapacitors.

News on the wires: Nanowires of titanium dioxide polymorph TiO2-B have been synthesized in high yield by a simple hydrothermal reaction between NaOH and TiO2-anatase followed acid washing subsequent heat treatment (see picture). Li+ ions electrons may be inserted into nanowires, which renders them ionically electronically conducting, then subsequently removed. Since discovery carbon nanotubes much interest has shown preparation greater chemical complexity, especially, recent times, oxide...
Purpose To identify the reproducible and nonredundant radiomics features (RFs) for computed tomography (CT). Materials Methods Two phantoms were used to test RF reproducibility by using test-retest analysis, changing CT acquisition parameters (hereafter, intra-CT analysis), comparing five different scanners with same inter-CT analysis). Reproducible RFs selected concordance correlation coefficient (as a measure of agreement between variables) variation (defined as ratio standard deviation...
There is much interest in Na-ion batteries for grid storage because of the lower projected cost compared with Li-ion. Identifying Earth-abundant, low-cost, and safe materials that can function as intercalation cathodes an important challenge facing field. Here we investigate such a material, β-NaMnO2, different structure from NaMnO2 polymorphs other compounds studied extensively past. It exhibits high capacity (of ca. 190 mA h g(-1) at rate C/20), along good capability (142 2C) retention...
Recent advances regarding the implementation of 3D printing for solid oxide fuel cells, batteries, solar energy and environmental applications are reviewed.
In the past few years a novel concept of Solid Oxide Fuel Cells (SOFC) has been developed: symmetrical (SSOFC). this configuration, same electrode material is used as anode and cathode. Several state-of-the-art SOFC materials have tested optimised to operate in such case lanthanum chromites traditionally interconnect materials, chromium manganites strontium titanates generally anodes typically cathodes. cell performances approximately 800 mW cm−2 ∼500 under H2 CH4 atmospheres obtained using...
Here we report the first synthesis of TiO2-B nanotubes by a simple hydrothermal route; lithium may be intercalated up to composition Li(0.98)TiO2 compared with Li(0.91)TiO2 for corresponding nanowires.

Capacity fade 0.16% per cycle compared 0.10% the corresponding nanowires. There an irreversible loss 29% on first but thereafter charge/discharge efficiency close 100%.
A stereolithography-based additive manufacturing technique has been used for the fabrication of advanced ceramics. customised 3D printer using a Digital Light Processing (DLP) projector as UV source built to fabricate green bodies from photosensitive resins loaded with 25–60 wt% alumina, 3- and 8-YSZ. The 3D-printed were then sintered in 1200–1500 °C exhibited thermal stability. As expected, higher ceramic loadings rendered objects density given sintering temperature. limit solid loading...
Molybdenum substituted lanthanum tungstate, La28–y(W1–xMox)4+yO54+δ (x = 0–1, y 0.923), was investigated seeking for an enhancement of the n-type electronic conductivity its use as a mixed electron–proton conductor in hydrogen gas separation membrane applications.

The effect on the activity in breast cancer models of small tyrosine kinase inhibitor dasatinib (DAS), either alone or combination with other antitumoral agents, has been recently explored. However, DAS is characterized by its low and highly pH-dependent solubility, which could lead to poor uptake drug limiting tumoral efficacy. Thus far, development safe efficient delivery vehicles improve therapeutic efficacy minimizing toxicity profile still required. In this work, a biodegradable...
