Recent progress and potential impact of modulation spectroscopy for narrow-gap HgCdTe
SHAO Jun,MA Li-Li,LV Xiang,WU Jun
红外与毫米波学报 , 2008,
Abstract: Recent progress of infrared photoreflectance and modulated photoluminescence techniques was outlined with special attention focused on the significant improvement of signal-to-noise ratio, spectral resolution and time consumption relative to the conventional techniques. Application of these techniques to molecular beam epitaxially grown HgCdTe films was given as examples, from which the potential impact of the techniques was foreseen on the optical study of narrow-gap semiconductors and inter-subband transition of wide-gap semiconductors with low-dimensional structures.

Abstract: 目标自动激活模型认为,目标是行为满意状态或结果在个体头脑中的表征,它能够通过相关情境自动激活。无意识目标的激活方式有语义激活、工具激活和人际激活。无意识目标追求与有意识目标追求在目标实现、目标投射和动机特征方面相似,但其行为产生机制有所不同。未来研究应该对无意识目标的机制及其具体应用进行深入的探讨。

Abstract: 长期以来,心理学对文化差异的研究以价值观为主导。2002年Leung等人提出了社会通则概念(Social Axiom),使得对文化差异的研究有了新载体。社会通则区别于价值观、社会态度、人格特质等概念,它是个体对于他人、社会、物质和精神世界的一般化信念,特指个体对两个概念或者两个实体关系的一般性认识。研究者编制的社会通则问卷具有良好的信效度。该问卷在40多个国家的应用表明,社会通则在不同文化和社会背景下具有共同的5个维度,即愤世嫉俗、社会多样性、付出有回报、宗教性和命运控制。社会通则的研究从新视角探讨了文化差异以及心理机制和行为表现的关系,为社会心理学提供了新的研究方向。

Acta Crystallographica Section E , 2011, DOI: 10.1107/s160053681005186x
Abstract: In the cation of the title compound, [Cu(C32H29NP2)2]BF4, the CuI atom is four-coordinated in a distorted tetrahedral geometry by four P atoms from two N,N-bis[(diphenylphosphanyl)methyl]aniline ligands. In the crystal, the cations are linked by C—H...π interactions, forming chains along the a axis. Intramolecular C—H...N and intermolecular C—H...F hydrogen bonds are also observed.

Abstract: In the title centrosymmetric compound, [Hg2Cl4(C26H22N6O)2], each HgII center adopts a distorted HgN3Cl2 trigonal bipyramidal coordination geometry, formed by two pyridine N atoms, one imine N atom and two chloride anions. Within the organic ligand, the oxadiazole ring is nearly coplanar with the two benzene rings [dihedral angles = 5.9 (4) and 6.5 (4)°] and nearly perpendicular to the two pyridine rings with the same dihedral angle of 77.4 (4)°. The two organic ligands bridge two HgII ions to form the macrocyclic complex. Intermolecular N—H...Cl and N—H...N hydrogen bonding helps to stabilize the crystal structure.

Abstract: In the title compound, {(C8H20N2)[Al(HPO4)(PO4)]}n, the AlIII atom is coordinated by four O atoms from two HPO42 and two PO43 groups in a distorted tetrahedral geometry. Each AlO4 unit shares four O atoms with four adjacent PO4 units, leading to an anionic chain along [100]. The negative charge of the chain is compensated by doubly protonated camphoric amine cations. N—H...O hydrogen bonds connect the cations and the anionic chains. O—H...O hydrogen bonds are present in the chain.

Abstract: OBJECTIVE: To observe the pathological changes of vascular aging in spontaneously hypertensive rats (SHRs), and the effects of extracts from Panax ginseng, Panax notoginseng (Burk.) and Ligusticum chuanxiong on vascular aging. METHODS: Vascular smooth muscle cells (VSMCs) isolated from thoracic aorta of Wistar-Kyoto (WKY) rats and SHRs were primarily cultured and divided into WKY group, SHR group, valsartan group, low-dose extract group and high-dose extract group. Aging situation of VSMCs was detected by senescence-associated β-galactosidase (SA-β-gal) staining; the cell cycle was analyzed by flow cytometry; mRNA and protein expressions of p16, cyclin D1, cyclin-dependent kinase 4 (CDK4) and retinoblastoma protein (Rb) were detected by real-time fluorescence quantitative polymerase chain reaction (PCR) and Western blotting. RESULTS: SA-β-gal stain showed that compared with the WKY group, number of SA-β-gal-positive cells in the SHR group was increased significantly (P<0.01); extracts from Panax ginseng, Panax notoginseng (Burk.) and Ligusticum chuanxiong reduced the number of SA-β-gal-positive cells in the SHR group (P<0.01). Flow cytometry analysis showed that the number of VSMCs in G1 phase was reduced and in S phase was increased significantly (P<0.05) in the SHR group compared with the WKY group, and the number of VSMCs in G1 phase was increased and in S phase was reduced significantly in the extracts groups (P<0.05). PCR result showed that compared with the WKY group, the mRNA expressions of p16 and Rb in the SHR group were reduced and those of cyclin D1 and CDK4 were increased significantly, the mRNA expressions of p16 and Rb in the extracts group were increased and mRNA expressions of cyclin D1 and CDK4 were reduced significantly. Western blotting result showed that compared with the WKY group, the protein expression of p16 in the SHR group was reduced and the protein expressions of cyclin D1, CDK4 and phospho-Rb were increased significantly (P<0.05), while the protein expression of p16 in the extracts group was increased and the protein expressions of cyclin D1, CDK4 and phospho-Rb were reduced significantly (P<0.05). CONCLUSION: The extracts from Panax ginseng, Panax notoginseng (Burk.) and Ligusticum chuanxiong can delay vascular aging of SHRs, which works by p16-cyclin D/CDK-RB pathways to inhibit VSMC proliferation.
