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.
Environmentally Responsible Product Assessments for the Automobiles Made in China

Abstract: This article discusses a general assessment of how the environmental performance of the automobile has changed over the years. We performed an SLCA and used the AT&T matrix and Delphi-technique to compare a 1990s era automobile(made in china) to one from the 2000s of China. From the comparison, we calculated 5 life stages of automobile production include premanufacturing, product manufacture, product delivery, product use and recycling. The comparison shows moderate environmental stewardship during resource extraction, packaging. The ratings during manufacturing and refurbishment/ recycling/ disposal are both poor, and during customer use are abysmal though it have some improvement. The overall rating of 1990s is far below what might be desired. In contrast, the overall rating for the 2000s vehicle is much better than that of the earlier vehicle but still leaving plenty of room for improvement. Key words: AT&T matrix, environment, LCA, SLCA, automobile Résumé: Cet article entreprend une évaluation générale du fait que comment la performance environnementale de l’automobile a changé ces dernières années. Nous avons effectué un SLCA et utilisé la matrice de l’AT&T ainsi que le technique Delphi afin de comparer un automobile des années 1990 (fabriqué en Chine) avec un autre des années 2000. A travers la comparaison, nous avons calculé 5 étapes de la production de l’automobile : préfabrication, fabricarion du produit, livraison du produit, utilisation du produit, recyclage. La comparaison montre un management environnemental modéré pendant l’extraction et l’empaquetage des ressources. Les évaluations durant la fabrication et la reconstruction /recyclage/ élimination sont toutes misérables, et pendant la période d’utilisation par les clients elle appara t épouvantable malgré des améliorations. L’évaluation générale des années 90 est loin de répondre à notre désir. Au contraire, celle des années 2000 est bien meilleure que la précédente, mais reste beaucoup à désirer.

Theoretical studies of the EPR parameters for Ni2+ and Co+ in MgO

Abstract: the electron paramagnetic resonance (epr) parameters (g factors and the hyperfine structure constants) for ni2+ and co+ in mgo are theoretically studied from the perturbation formulas of these parameters for a 3d8 ion in octahedral crystal-fields. in the computations, the ligand orbital and spin-orbit coupling contributions are taken into account using the cluster approach. the calculated epr parameters are in good agreement with the experimental data. the larger g factor and the smaller magnitude of the hyperfine structure constant for ni2+ as compared with those for co+ can be attributed to the higher spin-orbit coupling coefficient and the lower dipolar hyperfine structure parameter of the former, respectively.

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812028826
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.
