An increase in lattice constants and an order-disorder phase transition were observed in the magnesium aluminate spinel (MgAl
2 O4 ) powders after shock compression. Theoretical calculations on the basis of density functional theory confirm that the remarkable volume expansion in shocked MgAl2 O4 powders is closely related to the substantial site disorder in the MgAl2 O4 lattice. The calculations also show that the partially inverse MgAl2 O4 spinel with an inversion index of 0.7 represents the greatest disordered metastable phase and the most unstable structure.

Ti-10Fe-6Al alloy was rapidly solidified using single roller melt-spinning technique to obtain ribbons, which was developed and used for supercapacitor electrode materials for the first time through facile oxidation. After oxidation at 680 °C for 100 h, TiO
2 /Fe2 O3 /Al2 O3 nanocomposite on Ti-10Fe-6Al alloy ribbons consisting of numerous nanoparticles with average diameter of 90 nm was formed, which directly served as current collectors. For Ti-10Fe-6Al alloy foils cut from alloy ingot, oxidation product also showed particle shape but the diameter was far larger than that on oxided Ti-10Fe-6Al alloy ribbons. The ribbon electrode exhibited excellent electrochemical performance with areal capacitance of 10,500 µF cm−2 at current density of 40 µA cm−2 as well as long-term cycling stability of about 79.9% capacitance enhancement after 5000 cycles.

The oxidation behavior of AlON translucent ceramic was investigated both in non-isothermal (from room temperature to 1573 K) and isothermal (at 1373 and 1473 K) conditions. The mass gains, phase compositions and micromorphology of oxidized samples were examined by thermogravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopy (SEM), respectively. The results suggest that in non-isothermal environment the oxidation reaction starts at about 1173 K for both AlON bulk sample and powder. In isothermal condition, the mass gain indicates the two-stage reaction mechanism which starts with chemical reaction, followed by diffusion controlled stage. XRD patterns suggest that AlON is thermodynamically unstable and it partly decomposes into corundum phase Al2O3 and AlN during the oxidation process. SEM results indicate that different micromorphology is obtained at different temperatures in the oxidation process. The estimated apparent activation energy for the diffusion rate controlled stage from isothermal experiment is about 245.2 kJ/mol. [ABSTRACT FROM AUTHOR]

Chemical stability of (Bi
1/2 Na1/2 )TiO3 (BNT) ceramics against water was studied through a comparison experiment. Immersion of BNT in 0.01 M NaOH solution showed no noticeable influence, while BNT ceramics were seriously affected when hydrogen was deposited on them through the electrolysis of water in the solution: the capacitance was obviously decreased and the dielectric loss was dramatically increased in the low-frequency range. X-ray diffraction analysis indicated that hydrogen was first dissolved into BNT and then caused decomposition, with some other phases formed. As water-induced degradation is an important cause of degradation for piezoelectric devices, it is important to ensure that the chemical stability of BNT is not decreased when using doping and/or the formation of a solid-state solution with other perovskite-type oxides in order to improve the piezoelectric properties of BNT-based ceramics.

- Abstract
Highly c-axis oriented CaRuO3 thin films were prepared on LaAlO3 buffered Si(100) substrates at 650 °C by pulsed laser deposition. The buffer layer had a significant effect on the microstructure and electrical properties of the subsequent CaRuO3 thin films. Typical columnar grown CaRuO3 films were available using LaAlO3 as a buffer layer, although the buffer layer was not well-crystallized at the deposition temperature. The resistivity of the highly oriented CaRuO3 thin film was 287.8 μΩ·cm at room temperature. The film showed typical metallic behaviour and its resistivity was sufficiently low to be used as a buffer layer in superconductor tapes or electrode materials in dielectrics devices.

The authors have studied the effects of film thickness on the lattice strain and in-plane dielectric and ferroelectric properties of Ba
0.7 Sr0.3 TiO3 thin films epitaxially grown on LaAlO3 (001) single crystal substrates. With increasing film thickness from 20 to 300 nm, the in-plane lattice parameter (a) increased from 0.395 to 0.402 nm while the out-of-plane lattice parameter (c) remained almost unchanged, which led to an increased a/c ratio (tetragonality) changing from 0.998 to 1.012 and consequently resulted in a shift of Curie temperature from 306 to 360 K associated with an increase of the in-plane remnant polarization and dielectric constant of the film.

Transparent MgAl
2 O4 spinel nanoceramics have been sintered at relatively low-temperature (500–700 °C) under high pressure (2–5 GPa) using a hydrostatic press with high-temperature-calcined nanopowders. The morphology, nanostructure, optical property, and density of ceramics were analyzed by scanning electron microscopy, transmission electron microscopy, UV-VIS-IR transmission spectrum, and Archimedes draining method. The average grain size (<100 nm for all samples sintered) depends on the sintering pressure and temperature. The nanoceramics are highly transparent even though their relative densities are all less than 99%, due to the low or negligible light scattering from the nanosized grains and pores.

- Abstract
In the report, we explore a two-step efficient synthetic to purposefully fabricate three-dimensional (3D) NiCo2S4 nanosheets for advanced electrochemical supercapacitors. They were characterized for their structural, morphological and electrochemical properties by using XRD, SEM, TEM, cyclic voltammetry and charge discharge methods. The unique designed nanostructure exhibits a high specific capacitance (1257.1 F g−1 at current density 1 A g−1), good rate performance (75.7% retention for current increases around 20 times) and excellent cycling stability (80% retention at 5 A g−1 after 1000 cycles). We are the first step in the synthesis of 3D NiCo2S4 flowers, which have a specific capacitance of 700.7 F g−1 at the current density of 1 A g−1 and exhibit excellent cycling stability with 95% capacitance retention. The S-NiCo2S4//activated carbon asymmetric supercapacitor is can deliver a maximum energy density of 47.3 W h kg−1 at a power density of 477.3 W kg−1. Therefore, according to our investigation it can be concluded that the low cost and environmental friendly two-step approach from 3D NiCo2S4 nanoflowers to the 3D NiCo2S4 nanosheets could be used to deposit efficient 3D NiCo2S4 nanosheets for supercapacitor application.

- Abstract
Objective: To study hematopoietic stem cell transplantation-related bleeding prognosis and construct a bleeding prediction model. Methods: The clinical data of 555 patients with malignant hematologic diseases who underwent allogeneic hematopoietic stem cell transplantation between May 1(st) 2004, and April 1(st) 2012 was analyzed retrospectively, and a prediction model was constructed. Results: Of the 555 patients, a total of 302 (54.0% ) patients exhibited bleeding events of varying degrees, including 151 (27.0% ) with grade Ⅰ bleeding, 63 (11.0% ) with grade Ⅱ bleeding, 48 (9.0% ) with grade Ⅲ bleeding, and 40 (7.0% ) with grade Ⅳ bleeding. Multifactorial analysis showed that the overall mortality ( HR =12.53, 95% CI 7.91-19.87, P <0.001) and non-recurrence mortality ( HR =23.79, 95% CI 12.23-46.26, P <0.001) were higher in patients with higher bleeding grades (Ⅲ and Ⅳ bleeding) compared to those with lower bleeding grades. Additionally, the donor's underlying disease, graft-versus-host disease (GVHD) score, poor platelet reconstitution, and ineffective platelet transfusion were independently associated with bleeding risk. The bleeding model constructed using the above variables showed good accuracy (C-Index=0.934) , and its efficacy was significantly higher than previous bleeding models. Conclusion: Hematopoietic stem cell transplant patients are at increased risk of death after a bleeding event. The cross-validated bleeding risk prediction model is valuable for early intervention.

- Abstract
Tea plant (Camellia sinensis [L.] O. Kuntze) is a woody crop of high economic importance worldwide; however, information on the molecular mechanisms underlying the regulation of flower development in this species is limited. In the present study, two GLOBOSA (GLO) -like MADS-box genes, CsGLO1 and CsGLO2, were isolated from C. sinensis 'Ziyangzhong' and were characterized to elucidate their roles in flower development. We found that CsGLOl and CsGLO2 are nuclear-localized transcription factors without transactivation ability but with a robust interaction. They have similar patterns of expression, both mainly restricted to petals and stamens. Moreover, ectopic expression of either CsGLO1 or CsGLO2 in Arabidopsis thaliana resulted in a partial conversion of sepals to petals, suggesting full GLOBOSA functional activity. Our results indicate that CsGLO1 and CsGLO2 paralogs might redundantly contribute to petal and stamen, providing the first insight into their role in tea plant flower development.

- Abstract
Objective: To analyze the clinical characteristics, treatment and prognosis of 16 allogeneic hematopoietic stem cell transplantation (allo- HSCT)- associated thrombotic microangiopathy (TA- TMA) patients., Methods: The clinical data of 16 TA- TMA cases in 852 patients following allo- HSCT from Jan. 2013 to Jun. 2015 in the First Affiliated Hospital of Soochow University were retrospectively analyzed., Results: Of all the 852 allo-HSCT recipients, 16 patients were diagnosed as TA-TMA and the 1-year cumulative incidence of TA-TMA was (2.3±0.6)%. Among them, there were 9 males and 7 females, the median age was 41-year-old (12-54), and the median times of diagnosis of TA-TMA were 72 (21- 525) days after HSCT. Additionally, the median platelet counts, hemoglobin, percentage of schistocytes and Lactate dehydrogenase (LDH) levels were 20(11-36) ×10(9)/L, 74(56-99) g/L, 3% (2%- 13%) and 762(309-1 049) U/L, respectively. All 16 cases have normal ADAMTS13 level (over 60%), 10 patients had neurologic dysfunction and elevated creatinine were seen in 7. The major treatment of TA-TMA was withdrawn of calcineurin inhibitors, plasma exchange and corticosteroids. Finally, 8 patients achieved response after treatment and the other patients died of poor response. Compared with TA- TMA who achieved remission after therapy, those who got no response after interventions presented acute GVHD and they had higher schistocytes (62.5% cases>5% vs all cases ≤4%), LDH [826 (674-1 310) U/L vs 636 (309- 941) U/L] and serum creatinine levels [127 (70- 215) μmol/L vs 56 (22- 101) μmol/L]., Conclusion: TA-TMA was a severe complication after allo-HSCT, it could progress to multi-organ injury and was associated with poor outcome, the therapeutic efficacy depends on disease severity and coexisted complications.
