Rethinking the effect of salinity on nitrogen removal capacity of aerobic granular sludge from the perspective of size distribution and granular morphology.

Granular size induces the operation performance variation of aerobic granular sludge reactor, but the profound reasons are unrevealed. This study investigated the influence of granular size distribution on the reactor operation under salt stress. The effective nitrogen removal was achieved at ≤4% salinity, but declined at 6% salinity.

High internal-phase Pickering emulsions constructed using myofibrillar proteins from large yellow croaker: Effect of glycerol.

Exploring the emulsification of myofibrillar protein (MP) from large yellow croaker (Larimichthys crocea) could meet the demand for high-value development and utilization of fish proteins. Therefore, MPs as the emulsifier to form stable high internal-phase Pickering emulsions (HIPPEs) with the addition of glycerol and the effects of different glycerol addition ratios of HIPPEs were investigated. HIPPEs could be constructed by MPs with the glycerol addition at a ratio of 15 %-30 % (v/v) compared to those without the addition of glycerol.

New quantified climate reconstruction in southern China suggests a potential influence of winter cloud cover across East Asia during the Holocene.

Previous studies have advanced our understanding of paleoclimate features and dynamics in East Asia, particularly within the East Asian monsoon domain (EAMD) since the last glacial period. However, a lack of quantitative reconstructions in the boundary area between tropical and subtropical zones has largely hindered our spatial comprehension of the relationship between precipitation and temperature throughout the EAMD. In this study, we present a continuous pollen record from the Pearl River delta over the past 13.

Mo-Pb redox triggers self-enhanced removal and recovery of Pb with superselectivity.

Membrane-based electrodeposition (MED) has emerged as a promising approach for reversible removal-recovery of toxic but valuable Pb. However, limited by the low specificity of membrane deposition toward various heavy metal ions in MED, the selective removal of Pb remains an obstacle. Inspired by the soft-hard acid-base theory, here we developed a Pb-affinity electroactive membrane by incorporating MoS with the cation exchange membrane (CEM) to achieve a tandem Pb selective adsorption-deposition process.

Characterization and application of Cinnamaldehyde-loaded zein nanoparticles in a polyvinyl alcohol/chitosan film for silver pomfret () packaging.

This study aims to prepare and characterize cinnamaldehyde-loaded zein/sodium alginate nanoparticles (ZCNPs) and incorporate them into polyvinyl alcohol/chitosan (PVA/CS) bioactive films (PSCN) to investigate their compatibility, physicochemical properties, and their application as a preservation material for pomfret fish. The results indicate that the anionic sodium alginate coating improved the particle size, zeta potential, and PDI of zein nanoparticles. The ZCNPs were uniformly dispersed within the films, enhancing the mechanical properties and water vapor barrier performance.

The N-terminal polypeptide of a new shell matrix protein hicraqin accelerates the rate of calcium carbonate deposition.

Matrix proteins play important roles in shell formation by regulating the assembly of organic matrix and minerals. Here, we obtained a new matrix protein (hicraqin) from Hyriopsis cumingii. The amino acid sequence of hicraqin contains multiple aggregated (Gly)n (n > 2) residues, a feature unique to silk-like matrix proteins.

Comprehensive effects of sediment dredging on environmental risk and bioavailability of heavy metals from the sediment of Lake Taihu, China.

The comprehensive effects of environmental dredging on heavy metals (HM) are still uncertain. This study comprehensively evaluates the long-term effects of dredging on the environmental risk and bioavailability of HM (Cu, Ni, Zn, Pb, Cd, Cr, and As) in Lake Taihu, China, by comparing simulated dredged treated (D) and undredged (UD) sediment cores under in-situ conditions for one year. Threshold effect level (TEL), geological accumulation index (I), potential ecological risk index (RI), and ratios of secondary phase and primary phase (RSP) methods were used to assess the environmental risk of sediment HM; and the diffusive gradient in thin-films (DGT) technique was applied to assess the bioavailability of sediment HM.

Simultaneous exposure to microplastics and heavy metal lead induces oxidative stress, histopathological damage, and immune dysfunction in marine mussel Mytilus coruscus.

The increasing deposition of microplastics (MPs) in aquatic ecosystems is a worldwide concern. MPs can interact with other environmental pollutants, such as heavy metals, and change their toxicity. In this study, we focused on the effects of MPs and lead (Pb), as a toxic heavy metal, on marine mussel Mytilus coruscus under separate and co-exposure situations at environmentally relevant concentrations: MPs (1 mg/L) and Pb (50 μg/L).

Phytohormones as a novel strategy for promoting phytoremediation in microalgae: Progress and prospects.

Microalgal phytoremediation is a promising bioremediation approach that can achieve significant resource recovery while effectively removing pollutants. However, the toxicity of some pollutants in wastewater often induces stress responses in microalgae, reducing their pollutant removal efficiency. Recently, phytohormones have been identified as a novel solution to reduce these stress responses, enhancing microalgae growth and improving their ability to remove various pollutants from wastewater.

Spontaneous and environment induced genomic alterations in yeast model.

While genomic alterations are fundamental to biological evolution, enabling adaptation and diversity, they can also result in detrimental outcomes, such as the development of genetic diseases including cancer. The budding yeast serves as an exemplary model for investigating the mechanisms behind various genomic alterations, including point mutations, chromosomal rearrangements, and whole-chromosome aneuploidy. In this review, we highlight the application of genetic screening systems to assess the mutagenic effects of physical and chemical agents efficiently.

Harnessing Janus structures: enhanced internal electric fields in CN for improved H photocatalysis.

Homojunction engineering holds promise for creating high-performance photocatalysts, yet significant challenges persist in establishing and modulating an effective junction interface. To tackle this, we designed and constructed a novel Janus homojunction photocatalyst by integrating two different forms of triazole-based carbon nitride (CN). In this design, super-sized, ultrathin nanosheets of carbon-rich CN grow epitaxially on a nitrogen-rich honeycomb network of CN, creating a tightly bound and extensive interfacial contact area.

Energy consumption forecasting for laser manufacturing of large artifacts based on fusionable transfer learning.

This study presents an energy consumption (EC) forecasting method for laser melting manufacturing of metal artifacts based on fusionable transfer learning (FTL). To predict the EC of manufacturing products, particularly from scale-down to scale-up, a general paradigm was first developed by categorizing the overall process into three main sub-steps. The operating electrical power was further formulated as a combinatorial function, based on which an operator learning network was adopted to fit the nonlinear relations between the fabricating arguments and EC.
