| 1 | 多向锻造和单向轧制304不锈钢高温退火后的晶界面分布显示文摘固溶处理后的2组304不锈钢样品分别经应变量ε=2的多向锻造(MF)和单向轧制(DR)后,再经900℃高温退火2—120min.采用电子背散射衍射(EBSD)技术和五参数晶界面分析方法(FPA),研究了样品的晶界特征分布(GBCD)和晶界面分布(GBPD).结果表明,2组样品中∑3n(n=1,2,3)特殊晶界的比例均不超过45%,并且在退火过程中,非共格∑3晶界逐渐共格化,∑9和∑27晶界比例也随之下降.分别经MF和DR处理后再经120min退火的样品中,一般大角度晶界(过滤掉∑3n)一般均以(111)扭转晶界和(110)倾侧晶界为主,表明样品中均存在明显的晶界织构(GBT);在某些特定取向差条件下,一般大角度晶界的GBPD在样品中存在显著差异,表明退火之前的加工过程对304不锈钢的GBPD有显著影响. | 方晓英 刘志勇 Tikhonova M Belyakov A Kaibyshev R Rohrer G S 王卫国 | 2012 | 金属学报2012，48，8： | 9 |
| 2 | 冷轧退火后铁素体不锈钢的晶界面分布显示文摘采用EBSD技术测定了冷轧退火铁素体不锈钢样品单一截面(轧面)的取向成像显微图(OIM),采用直线拟合法重构出晶界迹线,利用五参数法对晶界面{hkl}的分布进行了统计分析.结果表明,经85%冷轧变形的样品再经780℃退火后,合金虽然不存在明显的晶粒取向织构,也不存在以特定轴角对为特征的晶界择优分布,但其晶界面{hkl}的分布却具有一定的择优特性,而且在不同退火阶段,随着平均晶粒尺寸由小变大,择优分布的晶界面随之改变.当平均晶粒尺寸为9μm时,择优分布的晶界面为{100}晶面,其分布密度超过平均值12%左右;随着晶粒的长大,当平均晶粒尺寸达到15μm时,择优分布的晶界面以{111}为主,其次为{100}和{112}晶面,其最高分布密度超过平均值10%左右.对于特定取向差晶界,这种晶界面的择优分布特性明显增强.分析认为,退火过程中某些低能晶界由于迁移速率低而被保留下来是晶界面分布存在择优性的重要原因. | 方晓英 王卫国 Rohrer G S 周邦新 | 2010 | 金属学报2010，46，4： | 3 |
| 3 | A machine-learned interatomic potential for silica and its relation to empirical models显示文摘Silica(SiO_(2))is an abundant material with a wide range of applications.Despite much progress,the atomistic modelling of the different forms of silica has remained a challenge.Here we show that by combining density-functional theory at the SCAN functional level with machine-learning-based interatomic potential fitting,a range of condensed phases of silica can be accurately described.We present a Gaussian approximation potential model that achieves high accuracy for the thermodynamic properties of the crystalline phases,and we compare its performance(and performance–cost trade-off)with that of multiple empirically fitted interatomic potentials for silica.We also include amorphous phases,assessing the ability of the potentials to describe structures of melt-quenched glassy silica,their energetic stability,and the high-pressure structural transition to a mainly sixfold-coordinated phase.We suggest that rather than standing on their own,machine-learned potentials for silica may be used in conjunction with suitable empirical models,each having a distinct role and complementing the other,by combining the advantages of the long simulation times afforded by empirical potentials and the near-quantum-mechanical accuracy of machine-learned potentials.This way,our work is expected to advance atomistic simulations of this key material and to benefit further computational studies in the field. | Linus C.Erhard Jochen Rohrer Karsten Albe Volker L.Deringer | 2022 | npj Computational Materials2022，，1： | 3 |
| 4 | 高效液相色谱-紫外检测法快速检测液态牛奶和奶粉中的三聚氰胺显示文摘将一种简单有效的处理液态牛奶和奶粉并结合高效液相色谱(HPLC)快速检测样品中三聚氰胺的方法与已被认可的高效液相色谱-紫外检测(HPLC-UV)方法进行了比较。利用醋酸铵缓冲液和乙腈作为流动相,AcclaimMixed-ModWCX-1柱能够更加快速地分离三聚氰胺并且显示出良好的保留能力。这种流动相能够防止离子对试剂损害色谱柱并能使分离方法适合与质谱联用。使用WCX-1柱的背景噪声小、检出限低。并且新发展的样品处理方法也能够降低劳动强度并具有更高的回收率。 | Jeff Rohrer Scott Lefferts | 2010 | 生命科学仪器2010，8，2： | 3 |

| 7 | Differential diagnosis in patients with suspected bile acid synthesis defects显示文摘AIM: To investigate the clinical presentations associated with bile acid synthesis defects and to describe identification of individual disorders and diagnostic pitfalls. METHODS: We describe semiquantitative determination of 16 urinary bile acid metabolites by electrospray ionization-tandem mass spectrometry. Sample preparation was performed by solid-phase extraction. The total analysis time was 2 min per sample. We determined bile acid metabolites in 363 patients with suspected defects in bile acid metabolism. RESULTS: Abnormal bile acid metabolites were found in 36 patients. Two patients had bile acid synthesis defects but presented with atypical presentations. In 2 other patients who were later shown to be affected by biliary atresia and cystic fibrosis the profile of bile acid metabolites was initially suggestive of a bile acid synthesis defect. Three adult patients suffered from cerebrotendinous xanthomatosis. Nineteen patients had peroxisomal disorders, and 10 patients had cholestatic hepatopathy of other cause. CONCLUSION: Screening for urinary cholanoids should be done in every infant with cholestatic hepatopathy as well as in children with progressive neurological disease to provide specific therapy. | Dorothea Haas Hongying Gan-Schreier Claus-Dieter Langhans Tilman Rohrer Guido Engelmann Maura Heverin David W Russell Peter T Clayton Georg F Hoffmann Jürgen G Okun | 2012 | World Journal of Gastroenterology2012，18，10： | 2 |
