Thermal conductivity of lightly Sr- and Zn-doped La$_2$CuO$_4$ single crystals

, 2003
Both ab-plane and c-axis thermal conductivities ($\kappa_{ab}$ and $\kappa_c$) of lightly doped La$_{2-x}$Sr$_x$CuO$_4$ and La$_2$Cu$_{1-y}$Zn$_y$O$_4$ single crystals ($x$ or $y$ = 0 -- 0.04) are measured from 2 to 300 K.

Occurrence characteristics of Sr in coal from Tashan Coal Mine in Datong,Shanxi Province

Meitan kexue jishu
Datong Coalfield was intruded by igneous intrusions in both the Indosinian (Late Permian to the end of the Triassic) and the Yanshan (Late Jurassic to the Early Cretaceous) periods，which caused contact metamorphism of the coal seam. Previous studies have

Spin Relaxation in a Quantized Hall Regime in Presence of a Disorder

, 2003
We study the spin relaxation (SR) of a two-dimensional electron gas (2DEG) in the quantized Hall regime and discuss the role of spatial inhomogeneity effects on the relaxation.

Lived and Care Experiences of Chronic Musculoskeletal Shoulder Pain in Australian Adults: A Qualitative Study

Arthritis Care &Research, EarlyView.
Objective Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centered care and informing local service pathways and care guidelines or standards.

Study on the modified NaAlCl4/ZSM-5 catalysts —catalytic performance of the disproportionation of chlorotrimethyl and trichloromethyl silanes(NaAlCl4/ ZSM-5分子筛催化剂的改性研究)

Zhejiang Daxue xuebao. Lixue ban, 2010
前期工作表明NaAlCl4/ZSM-5分子筛有较好的催化一甲基硅烷和三甲基硅烷制备二甲基硅烷活性.本文通过浸渍法制备了一系列的用La(NO3)3改性及Sr(NO3)2改性的NaAlCl4/ZSM-5分子筛催化剂.结果表明La(NO3)3的加入对反应活性有一定程度的提高,当加入La(NO3)3的量为5%时,二甲产率最高,为68.24%.当加入Sr(NO3)2的量为3%时的效果最好,二甲含量为77.63%.采用IR表征的结果与实验结果比较吻合.用量子化学计算对所得结果进行了理论解释.
