Cobalt-doped tin disulfide catalysts for high-capacity lithium-air batteries with high lifetime.

Dual electrolyte lithium-air batteries have received widespread attention for their ultra-high energy density. However, the low internal redox efficiency of these batteries results in a relatively short operating life. SnS is widely used in Li-S batteries, Li-ion batteries, photocatalysis, and other fields due to the high discharge capacity in batteries.

Environmentally stable and stretchable polymer electronics enabled by surface-tethered nanostructured molecular-level protection.

Stretchable polymer semiconductors (PSCs) are essential for soft stretchable electronics. However, their environmental stability remains a longstanding concern. Here we report a surface-tethered stretchable molecular protecting layer to realize stretchable polymer electronics that are stable in direct contact with physiological fluids, containing water, ions and biofluids.

Identification of Genetic Diversity, Pyrrocidine-Producing Strains and Transmission Modes of Endophytic Fungi from Crops.

Genotyping by sequencing (GBS) was used to reveal the inherent genetic variation within the haploid fungi isolated from diverse germplasm, including modern and its wild progenitors-the teosintes. In accordance with broad host relationship parameters, GBS analysis revealed significant host lineages of genetic diversity, indicating that genetic variation may associate with different evolutionary histories of host species or varieties. Based on a recently identified PKS-NRPS gene responsible for pyrrocidine biosynthesis in fungi, a novel PCR assay was developed to discriminate pyrrocidine-producing strains.

Coexistence of silver ion and tetracycline at environmentally relevant concentrations greatly enhanced antibiotic resistance gene development in activated sludge bioreactor.

Antibiotic resistance has become a global public health problem. Recently, various environmental pollutants have been reported to induce the proliferation of antibiotic resistance. However, the impact of multiple pollutants (e.

In Situ Electrochemical Fabrication of Ultrasmall Ru-Based Nanoparticles for Robust NH Oxidation.

Ultrasmall Ru nanoparticles is expected as a potential alternative to Pt for efficient hydrazine oxidation (HzOR). However, preparation of ultrasmall and well-distributed Ru nanoparticles usually suffered from the steps of modification of supports, coordination, reduction with strong reducing reagents (e.g.

Integrated measurement of intracellular proteins and transcripts in single cells.

Biological function arises from the interplay of proteins, transcripts, and metabolites. An ongoing revolution in miniaturization technologies has created tools to analyze any one of these species in single cells, thus resolving the heterogeneity of tissues previously invisible to bulk measurements. An emerging frontier is single cell multi-omics, which is the measurement of multiple classes of analytes from single cells.

Does gibberellin biosynthesis play a critical role in the growth of Lolium perenne? Evidence from a transcriptional analysis of gibberellin and carbohydrate metabolic genes after defoliation.

Global meat and milk production depends to a large extent on grazed pastures, with Lolium perenne being the major forage grass in temperate regions. Defoliation and subsequent regrowth of leaf blades is a major and essential event with respect to L. perenne growth and productivity.

Transcript profiling of fructan biosynthetic pathway genes reveals association of a specific fructosyltransferase isoform with the high sugar trait in Lolium perenne.

Lolium perenne cultivars with elevated levels of fructans in leaf blades (high sugar-content grasses) have been developed to improve animal nutrition and reduce adverse environmental impacts of pastoral agricultural systems. Expression of the high sugar trait can vary substantially depending on genotype×environment (G×E) interactions. We grew three potential high sugar-content and a control cultivar in three temperature regimes and quantified water soluble carbohydrates (WSCs) and the expression of all functionally characterised L.

Transcriptional regulation of phosphate transporters from Lolium perenne and its mycorrhizal symbionts in response to phosphorus supply.

Phosphate (P) uptake is critical for plant growth, but to date little is known about P uptake and transport in the pasture grass Lolium perenne L. We have identified a putative P transporter (PT) from L. perenne mycorrhizal roots (LpPT1) and assessed its transcriptional regulation by soil P availability and mycorrhizal colonisation.

Functional characterisation and transcript analysis of an alkaline phosphatase from the arbuscular mycorrhizal fungus Funneliformis mosseae.

Alkaline phosphatases (ALP) in arbuscular mycorrhizal (AM) fungi have been suggested to be involved in transfer of phosphate from the mycorrhizal fungus to the host plant, but exact mechanisms are still unknown, partially due to the lack of molecular information. We isolated a full-length cDNA (FmALP) from the AM fungus Funneliformis mosseae (syn. Glomus mosseae) showing similarity with putative ALP genes from Rhizophagus intraradices (syn.

One-step hydrotreatment of vegetable oil to produce high quality diesel-range alkanes.

A one-step hydrotreatment of vegetable oil combining deoxygenation and isomerization to directly produce low cloud point, high quality diesel is devised. The Pt/zeolite bifunctional catalysts prepared by using SAPO-11 and ZSM-22 zeolites as supports are used in this process. Catalytic reactions are conducted in a fixed-bed reactor under a hydrogen atmosphere.
