采用基于密度泛函理论的第一性原理平面波超软赝势计算方法,研究了In、Scp型掺杂对SrTiO3母体化合物稳定性、电子结构和光学性质的影响.计算结果表明:掺杂后,SrIn0.125Ti0.875O3和SrSc0.125Ti0.875O3的稳定性降低,体系显示p型简并半导体特征,掺杂仅引起杂质原子近邻区域的几何结构发生变化.同时,SrIn0.125Ti0.875O3和SrSc0.125Ti0.875O3体系的光学带隙分别展宽0.35、0.30eV,光学吸收边发生蓝移,在1.25-2.00eV的能量区间出现新的吸收峰,该吸收峰与体系Drude型自由载流子的激发相关.此外,SrIn0.125Ti0.875O3和SrSc0.125Ti0.875O3体系的可见光透过率有了明显的提高,在350-625nm波长范围透过率高于85%.掺杂原子在费米能级处低的电子态密度限制了跃迁概率和光吸收.大的禁带宽度、小的跃迁概率和弱的光吸收是SrIn0.125Ti0.875O3和SrSc0.125Ti0.875O3体系具有较高光学透明度的原因.

Understanding how plants respond to drought can benefit drought resistance （DR） breeding. Using a non-destructive phenotyping facility, 51 image-based traits （i-traits） for 507 rice accessions were extracted. These i-traits can be used to monitor drought responses and evaluate DR. High heritability and large variation of these traits was observed under drought stress in the natural population. A genome-wide as- sociation study （GWAS） of i-traits and traditional DR traits identified 470 association loci, some containing known DR-related genes. Of these 470 loci, 443 loci （94%） were identified using i-traits, 437 loci （93%） co- localized with previously reported DR-related quantitative trait loci, and 313 loci （66.6%） were reproducibly identified by GWAS in different years. Association networks, established based on GWAS results, revealed hub i-traits and hub loci. This demonstrates the feasibility and necessity of dissecting the complex DR trait into heritable and simple i-traits. As proof of principle, we illustrated the power of this integrated approach to identify previously unreported DR-related genes. OsPP15 was associated with a hub i-trait, and its role in DR was confirmed by genetic transformation experiments. Furthermore, i-traits can be used for DR linkage analyses, and 69 i-trait locus associations were identified by both GWAS and linkage analysis of a recom- binant inbred line population. Finally, we confirmed the relevance of i-traits to DR in the field. Our study pro- vides a promising novel approach for the genetic dissection and discovery of causal genes for DR.

Graphene‐supported BiFeO3 (rG‐BiFeO3) was synthesized by the hydrothermal method and used for the efficient removal of ammonia under visible light. X‐ray diffraction, transmission electron microscopy,Fourier transform infrared spectroscopy, Raman spectroscopy, and ultraviolet‐visiblediffuse reflectance spectroscopy were conducted to characterize the rG‐BiFeO3. The specific surfacearea of the rG‐BiFeO3 catalyst was 48.6 m2/g, larger than that of BiFeO3 (21.0 m2/g). When used as aheterogeneous photocatalyst, rG‐BiFeO3 achieved 91.20% degradation of a NH3‐N solution (50mg/L) at pH = 11 under visible‐light irradiation in the absence of hydrogen peroxide. The degradationof ammonia followed pseudo‐first‐order kinetics, and the catalyst retained high photocatalyticactivity after seven reaction cycles. Study of the mechanism showed that the holes, superoxide anion radicals, and hydroxyl radicals, arising from the synergy between graphene and BiFeO3, oxidized NH3 directly to N2.

The SrTiO3 ： Pr^3＋ material, co-doped with monovalent Li^＋ , divalent Mg^2＋ , and trivalent Al^3＋ was prepared by a new sol-gel method. The phase and crystallinity of the synthesized materials were investigated by powder X-ray diffraction（XRD） and scanning electron microcopy（SEM）. Among the co-doped ion, Al^3＋ incorporation caused the least lattice change and had the best crystallinity. Photoluminescence spectra were taken to investigate the luminescence characteristics. We observed a red luminescence change of SrTiO3 ： Pr^3＋ after being co-doped, and a best enhancement on the red luminescence with the trivalent Al^3＋ was observed. The present results indicated that the charge defect associated with Al^3＋ has led to charge compensation of Pr^＋ and also implied that the charge defects（usually the second dopant ions replacing the A or B sites in the lattice） which are closer to PrSr^＋ contribute more to the red luminescence enhancement.

Background Humoral immunity is an important factor for long-term survival of renal allograft. Here we performed a four-year follow-up to explore the clinical significance of monitoring anti-human leukocyte antigens （HLA） and anti-major histocompatibility complex class I-related chain A （MICA） antibody expression after kidney transplantation. Methods We obtained serial serum samples from 84 kidney transplant patients over a four-year period. All patients were followed up at least 6 months after transplantation and had at least two follow-up points. Anti-HLA and anti-MICA antibody titres and serum creatinine （SCr） levels were evaluated at each follow-up. Patients were divided into 4 groups： HLA（＋） MICA（-）, HLA（-）MICA（＋）, HLA（＋）MICA（＋） and HLA（-）MICA（-）. The impact of post-transplant antibody level on kidney allograft function was evaluated. Results Antibodies were detected in 38.1% （32/84） of the renal allograft recipients. HLA, MICA and HLA＋MICA expression was observed in 18.89%, 14.44% and 5.93% of the recipients respectively. The most frequent anti-HLA and anti-MICA specific antibodies identified were All, A24, A29, A32, A33, A80; B7, B13, B37; DR17, DR12, DR18, DR52, DR53, DR1, DR4, DR9, DR51; DQ7, DQ4, DQ8, DQ2, DQ9, DQ5, DQ6 and MICA02, MICA18, MICA19, MICA07, MICA27. As the time after transplantation elapsed, more recipients developed de novo antibody expression. Total 11.91% （10/84） of the recipients had de novo antibody expression during the follow up. The average level of SCr and the percentage of recipients with abnormal allograft function were significantly higher in recipients with anti-HLA and/or anti- MICA antibody expression than those without. The appearance of anti-HLA and anti-MICA antibody expression always preceded the increase in SCr value. Conclusions Anti-HLA and anti-MICA antibody expression has predictive value for early and late allograft dysfunction. The presence of donor specific antibody is detrimental to graft function and graft survival

The adsorption and reaction of CO on SrTiO3 （100） surface with and without surface oxygen vacancy are investigated by the first-principles calculation based on the density functional theory. The calculated results reveal that the oxygen vacancy site prefers to the activation of the C-O bond. The adsorption energies increase to 1.0855 and 0.3245eV for defect-CO and defect-OC orientations, respectively. Particularly the C-O bond is elongated by about 0.1285 ？ in the defect-OC orientation compared with that in the Ti-OC one without surface oxygen vacancies. There is predominantly a chemisorption mechanism between the CO molecule and the surface in the defect-CO orientation.
