Elemental selenium(Se), as the world’s first but long-neglected photovoltaic material, has regained great interest recently in tandem solar cells as top cells due to its wide bandgap(~1.8 eV), simple, non-toxic and earth-abundant composition, and intrinsic environmental stability. In particular, Se possesses the lowest melting point of 217 °C among the photovoltaic absorbers reported so far, endowing Se with a unique advantage of film fabrication by blade coating the Se melt on substrate. However, the poor wettability of Se melt on widely-used photovoltaic functional layers such as TiO_(2) limits its melt processing. Here we introduce a wettability-modification strategy that decreases the contact angle of Se melt on substrate and improves the wettability by appropriately enhancing the heating temperature of molten Se while avoiding Se volatilization. We further reveal the mechanism of the inherent air stability of Se that originates from the high activation energy of oxygen chemisorption on Se(3.21 eV). This enables the realization of compact Se films through melt-based blade coating in ambient air. The resulting Se solar cells exhibit an efficiency of 3.5%. Unencapsulated devices show no efficiency loss after 1,000 h of storage under ambient conditions.

OBJECTIVE: To observe the effect of moxa-burning heat stimulating acupoints of Liangmen(ST 21)and Zusanli(ST 36) on the proliferation and apoptosis signaling proteins in rats with stress-induced gastric ***: Forty rats were randomly divided into four groups: negative control(NC), ulcer control(UC), acupoints of stomach meridian(ASM), and acupoints control(AC). The acute gastric ulcer model was established by bound and water *** in NC and UC groups didn't receive any moxa-burning heat stimulating treatment, while rats in ASM and AC groups were treated with buringmoxa heat stimulating the acupoints of Liangmen(ST 21) and Zusanli(ST 36) and their controlled points, respectively. Rats in all groups were sacrificed after 12 consecutive days treatment. The ulcer index was evaluated by using Guth's *** expression of tumor necrosis factor-alpha(TNF-α), apoptotic protease activating facter-1(Apaf-1), Caspase-3, p21 activated kinase 1(PAK1),extracellular regulated protein kinases 2(ERK2),phosphorylated ERK2(p ERK2), phosphoinositide3-kinase(PI3K) and RAC-alpha serine/threonine-protein kinase(Akt) in gastric mucosa was detected by enzyme linked immunosorbent assay(ELISA).RESULTS: Compared with UC group, the ulcer index of ASM and AC groups decreased, and the injured gastric mucosa was improved, the expression of TNF-α, Apaf-1 and Caspase-3 in gastric mucosa was significantly reduced(P < 0.05), while the ex-pression of PAK1, ERK2, p ERK2, PI3 K and Akt in gastric mucosa was significantly increased(P < 0.05).And ASM showed better effect than AC group(P <0.05).CONCLUSION: Moxa-burning Heat stimulating of Liangmen(ST 21) and Zusanli(ST 36) could promote the recovery of gastric mucosal lesion probably by inhibiting cell apoptosis and promoting cell proliferation in stress-induced gastric ulcer.

Data processing is a basic and crucial factor in seismic exploration,which can influence the effect of subsequent processing directly. Thus the selection of appropriate method for data processing is one of the most important tasks throughout the work. By simulating,the authors analyze and compare Fractional Fourier Transform( FRFT) and Wigner-Ville distribution( WVD),then summarize the similarities and advantages and disadvantages of the two methods. The results reveal that FRFT is more effective and suitable for application in seismic exploration than WVD.

Tectonic evolution of the Tethys and the boundary between the Gondwanaland and the Eurasia during the Carboniferous and Permian remain hotly debated. Qiangtang region in the Qinghai-Tibet Plateau may be a key place to study these problems. A paleomagnetic study was conducted on the Late Paleozoic rocks in the northern Qiangtang region （33.7°N, 86.7°W）, Tibet. Two sites （21 samples） in the Upper Carboniferous, eleven sites （101 samples） in the Permian, and two sites （16 samples） in the Lower Triassic were investigated. The rock magnetic data revealed hematite and magnetite as the main magnetic carders. In stepwise thermal demagnetization and/or combined alternating field （AC） demagnetization, two characteristic components in the majority of the samples were identified as （1） the Low-temperature Component （LTC）, characterized by northerly decli- nation and moderate to steep inclination, corresponding to a pole position overlay with the present North Pole. A minority of the samples present single component, and their directions are the same as （2） the High-temperature Component （HTC） of double components. The combined single-component and HTC data of the Permian can pass the R-test at 95% level and the F-test at 99% level, as well as the BC-test. The pole position from the Late Carboniferous is at 31.8°S, 45.7°E with dp=2.1, dm=3.9, that from the Early and Middle （Late） Permian is at 31.7°S, 46.8°E with @=9.2, dm=16.9 （34.4°N, 54.1°E with dp=6.9, dm=1 2.5） respectively, and that from the Early Triassic is at 16.9°S, 22.5°E with dp=4.9, dm=9.2. These pole positions are different from the other poles for the Qiangtang Block, which suggests the single-component and HTC directions are probably a primary magnetization and the northern Qiangtang Block was paleogeographically situated at low latitudes in the Northern Hemisphere in the Late Paleozoic.
