Strain FF17, a Gram-negative, obligate aerobic, motile, pink-pigmented, and methylotrophic bacterium, was selected for a polyphasic taxonomic investigation due to its capacity for aggregation, or floc formation. The predominant respiratory quinone observed was Q-10, accounting for 83.36% of the total, while the major fatty acids were summed feature 8 (18:1 w6c and/or 18:1 w7c).

3D mixed ion/electron-conducting scaffolds for stable sodium metal anodes.

Sodium (Na) metal batteries represent an optimal choice for the forthcoming generation of large-scale, cost-effective energy storage systems. However, Na metal anodes encounter several formidable challenges during the Na plating and stripping processes, which encompass the formation of an unstable solid electrolyte interface, uncontrollable dendrite growth, and infinite volume expansion. These issues result in a reduced Coulombic efficiency, shortened battery lifespan, and potential safety hazards, thereby constraining their commercial development.

Trace metals in sediment from Chaohu Lake in China: Bioavailability and probabilistic risk assessment.

Bioavailability-based probabilistic risk assessment is an effective approach for risk characterization of trace metals towards aquatic species. However, it has not been routinely applied in lake management due to limited research. In this study, Chaohu Lake (Anhui Province, China) was selected as a case study, and total and bioavailable concentrations of trace metals in surface sediment were investigated using chemical extraction and diffusive gradients in thin films (DGT).

Source tracing with cadmium isotope and risk assessment of heavy metals in sediment of an urban river, China.

The Nanfei River was one of dominant inflowing rivers of the fifth largest freshwater Chaohu Lake in China, which had been subjected to increasing nutrients and contaminants from population expansion, rapid industrialization and agricultural intensification in recent decades. In present study, surface sediment from the Nanfei River was collected to investigate the anthropogenic impact on distribution and bioavailability of heavy metals. Possible Cd sources along the river were constrained by using Cd isotope signatures and labile concentrations of heavy metals in sediment were determined through the DGT technique for risk assessment.

A Metal-Organic-Framework-Derived g-C N /α-Fe O Hybrid for Enhanced Visible-Light-Driven Photocatalytic Hydrogen Evolution.

As one of the most efficient systems for photocatalytic hydrogen evolution, the Z-Scheme system, consisting of different semiconductors with a reversible donor-acceptor pair, has attracted great attention. Considering the non-toxicity and low cost of photocatalysts, a series of g-C N /α-Fe O hybrids were rationally constructed based on the Z-Scheme mechanism for the first time, using a metal-organic framework template approach that can fine tune the compositions and properties of the hybrids. An optimized hybrid, g-C N /α-Fe O -2, exhibited prominent photocatalytic water splitting performance with a visible light response.

An Efficient, Visible-Light-Driven, Hydrogen Evolution Catalyst NiS/Zn Cd S Nanocrystal Derived from a Metal-Organic Framework.

Photocatalytic water splitting for hydrogen production using sustainable sunlight is a promising alternative to industrial hydrogen production. However, the scarcity of highly active, recyclable, inexpensive photocatalysts impedes the development of photocatalytic hydrogen evolution reaction (HER) schemes. Herein, a metal-organic framework (MOF)-template strategy was developed to prepare non-noble metal co-catalyst/solid solution heterojunction NiS/Zn Cd S with superior photocatalytic HER activity.

Metal-Organic Framework-Derived ZnO/ZnS Heteronanostructures for Efficient Visible-Light-Driven Photocatalytic Hydrogen Production.

Developing highly active, recyclable, and inexpensive photocatalysts for hydrogen evolution reaction (HER) under visible light is significant for the direct conversion of solar energy into chemical fuels for various green energy applications. For such applications, it is very challenging but vitally important for a photocatalyst to simultaneously enhance the visible-light absorption and suppress photogenerated electron-hole recombination, while also to maintain high stability and recyclability. Herein, a metal-organic framework (MOF)-templated strategy has been developed to prepare heterostructured nanocatalysts with superior photocatalytic HER activity.

Polyoxometalate-Based Metal-Organic Frameworks as Visible-Light-Induced Photocatalysts.

Two stable 3D polyoxometalate-based metal-organic frameworks (PMOFs), [Cu(trz)(HO)][α-SiWO]·2HO (1) and [Cu(trz)Cl][α-PWO] (2) (Htrz = 1- H-1,2,4-triazole) based on Keggin-type POMs were successfully obtained and fully characterized. The basic building units of the two PMOFs are [Cu(trz)], but polyoxoanion (POA) template effect leads to different structures and properties: 1 represents an interesting example that [α-SiWO] locate in the nine-membered Cu-trz rings through Cu···O weak interactions to form a 3D framework, whereas 2 shows a 3D structure constructed from 2D bilayer cationic network [Cu(trz)Cl] and [α-PWO] lying in the adjacent layers via Cu···O weak interactions. PMOF 1 as unusual visible-light photocatalyst exhibit significantly enhanced photocatalytic activity under visible-light and excellent stability during the photocatalysis process for recovering and recycling, as well as photocatalytic hydrogen evolution activity.

Comparison of the dissipation behaviour of three neonicotinoid insecticides in tea.

The dissipation behaviour of three neonicotinoids - thiamethoxam, imidacloprid and acetamiprid - was compared in tea shoots, in Chinese green and black tea, and after tea infusion in hot water. The simple and rapid analytical procedures for the quantification of these three residues in these matrices were developed using HPLC with ultraviolet (UV) detection.
