Perovskite solar cells （PVSCs） have attracted extensive studies due to their high power conversion efficiency （PCE） with low-cost in both raw material and processes. However, there remain obstacles that hinder the way to their commer- cialization. Among many drawbacks in PVSCs, we note the problems brought by the use of noble metal counter electrodes （CEs） such as gold and silver. The costly Au and Ag need high energy-consumption thermal evaporation process which can be made only with expensive evaporation equipment under vacuum. All the factors elevate the threshold of PVSCs＇ commercialization. Carbon material, on the other hand, is a readily available electrode candidate for the application as CE in the PVSCs. In this review, endeavors on PVSCs with low-cost carbon materials will be comprehensively discussed based on different device structures and carbon compositions. We believe that the PVSCs with carbon-based CE hold the promise of commercialization of this new technology.

One Gram-negative Bacillus was isolated from a brain sample of a pig with neurological *** examination showed meningitis at necropsy. Ochrobactrum anthropi (O. anthropi) was successfully isolated from the brain sample and was confirmed by biochemical reaction results (API 20 NE) and gene sequencing. The strain was highly resistant to b-lactam antibiotics. Mice were experimentally infected with O. anthropi and showed typical meningitis. This is the first report on O. anthropi isolated from a pig, and indicates that O. anthropi may have a broader host spectrum of infection.

Owing to almost unmatched volumetric energy density, Li-based batteries have dominated the portable electronic industry for the past 20 years. Not only will that continue, but they are also now powering plug-in hybrid electric vehicles and zero-emission vehicles. There is impressive progress in the exploration of electrode materials for lithium-based batteries because the electrodes(mainly the cathode) are the limiting factors in terms of overall capacity inside a battery. However, more and more interests have been focused on the electrolytes, which determines the current(power) density, the time stability, the reliability of a battery and the formation of solid electrolyte interface. This review will introduce five types of electrolytes for room temperature Li-based batteries including 1) non-aqueous electrolytes, 2) aqueous solutions, 3)ionic liquids, 4) polymer electrolytes, and 5) hybrid electrolytes. Besides, electrolytes beyond lithium-based systems such as sodium-, magnesium-, calcium-, zinc-and aluminum-based batteries will also be briefly discussed.
