Low temperature is one of the most common environmental stresses affecting plant growth and agricultural production. Serine/threonine protein phosphatases 2C (PP2Cs) have been suggested to play an important role in stress signaling. To identify potential new member of the PP2C proteins in maize and investigate its functions for stress responses, the ZmPP2C2(More)
The large-scale practical application of fuel cells cannot come true if the high-priced Pt-based electrocatalysts for oxygen reduction reaction (ORR) cannot be replaced by other efficient, low-cost, and stable electrodes. Here, based on density functional theory (DFT), we exploited the potentials of layered SiC sheets as a novel catalyst for ORR. From our(More)
Net Photosynthetic rate(Pn), relative electrical conductivity and MDA content of 11 fennel varieties were tested using LI-6400 portable photosynthesis system. The results showed that Pn of XJ0710 has distinct difference with other varieties in which there is no obvious difference. But the relative electrical conductivity and MDA of the varieties have(More)
Bacterial vaginosis frequently persists, even after treatment. The role of some strains of bacteria associated with bacterial vaginosis treatment failure remains poorly defined. The aim of our study was to define the risk of bacterial vaginosis treatment failure, including pre-treatment detection of specific vaginal bacteria. Bacterial vaginosis is present(More)
After being affected by naturally low temperature (-4~0℃), the changes of relative electrical conductivity and MDA content of 11 fennel varieties were tested. The experiment studied the relationship between the cold resistance and changes of relative electrical conductivity and MDA content of varieties. The results showed that the relative electrical(More)
To increase Pt utilization for oxygen reduction reaction (ORR) in fuel cells, reducing particle sizes of Pt is a valid way. However, poisoning or surface oxidation limits the smallest size of Pt particles at 2.6 nm with a low utility of 20%. Here, using density functional theory calculations, we develop a core-shell Al13@Pt42 cluster as a catalyst for ORR.(More)
