High-Flux and Robust CoO Mesh for Efficient Oil/Water Separation in Harsh Environment.

Material with special wettability for oil/water separation has drawn more and more attention, since the oil spill accidents and industrial processing are growing in frequency and in volume. A superhydrophilic and underwater superoleophobic mesh was prepared by introducing CoO on a stainless steel mesh, through a simple hydrothermal process and subsequent calcination. The as-prepared CoO mesh can not only separate various oil/water mixtures with high efficiency and high flux, but also work effectively in harsh environment such as highly acidic, alkaline, and salty solutions.

A New Free-Standing Aqueous Zinc-Ion Capacitor Based on MnO-CNTs Cathode and MXene Anode.

Restricted by their energy storage mechanism, current energy storage devices have certain drawbacks, such as low power density for batteries and low energy density for supercapacitors. Fortunately, the nearest ion capacitors, such as lithium-ion and sodium-ion capacitors containing battery-type and capacitor-type electrodes, may allow achieving both high energy and power densities. For the inspiration, a new zinc-ion capacitor (ZIC) has been designed and realized by assembling the free-standing manganese dioxide-carbon nanotubes (MnO-CNTs) battery-type cathode and MXene (TiCT) capacitor-type anode in an aqueous electrolyte.

Analysis of microbial community in a continuous flow process at gene and transcription level to enhance biological nutrients removal from municipal wastewater.

In biological municipal wastewater treatment, gene level analysis of community structure could not determine functional genes that actually played a role and expression of viable microorganism. In this study, reverse transcriptional PCR (RT-PCR), cDNA high throughput sequencing and transcriptional activity analysis were conducted to investigate active microbial community with nitrogen and phosphorus removal from municipal wastewater. RT-PCR and correlation heatmap analysis suggested that transcriptional activities of bacteria had strong correlation with performance of nitrogen and phosphorus removal, they might be therefore regarded as an indicator for wastewater treatment monitoring.

Metacaspase gene family in Rosaceae genomes: Comparative genomic analysis and their expression during pear pollen tube and fruit development.

Metacaspase (MC), which is discovered gene family with distant caspase homologs in plants, fungi, and protozoa, may be involved in programmed cell death (PCD) processes during plant development and respond abiotic and biotic stresses.

Phylogenetic analysis suggested that the MC genes could be grouped into three clades: Type I*, Type I and Type II, which was supported by gene structure and conserved motif analysis.
