Roxarsone (ROX) is the main form of As pollution in the world, and developing effective methods for its elimination is beneficial to human health and ecological environment. Herein, we report glutaraldehyde-crosslinked chitosan encapsulated CoCe-LDH as an outstanding catalyst for the advanced oxidation of ROX and the efficient adsorption of inorganic arsenic. 100% of ROX and more than 98.5% of As(III)/As(V) were eliminated, and over 99.3% of remained inorganic arsenic was oxidized to low toxicity As(V) in the PMS-activation system, and some specific properties of LDH are considered the main reasons. The hierarchical anion exchange has been confirmed to be beneficial for constructing a high concentration PMS inter layer microenvironment. And the unique reverse electron transfer process induced the 100% selective production of singlet oxygen. This work not only develops an advanced ROX removal method, but also provides a new understanding of LDH-based advanced oxidation process. © 2024, The Authors. All rights reserved.

Five negatively charged organic compounds with different structures, sodium methane sulfonate(MS), sodium benzene sulfonate(BS), sodium 6-hydroxynaphthalene-2-sulfonate(NSS), sodium dodecyl sulfate(SDS), and sodium dodecyl benzene sulfonate(SDBS), were used to examine the fouling of an anion exchange membrane(AEM) in electrodialysis(ED),to explore the effect of molecular characteristics on the fouling behavior on the AEM and changes in the surface and electrochemical properties of the AEM. Results indicated that the fouling degree of the AEM by the different organics followed the order:SDBS > SDS > NSS > BS > MS. SDBS and SDS formed a dense fouling layer on the surface of the AEM, which was the main factor in the much more severe membrane fouling, and completely restricted the transmembrane ion migration. The other three organics caused fouling of the AEM by adsorption on the surface and/or accumulation in the interlayer of the AEM, and exhibited almost no influence on the transmembrane ion migration. It was also concluded that the organics with benzene rings caused more severe fouling of the AEM due to the stronger affinity interaction and steric effect between the organics and the AEM compared with organics with aliphatic chains.

Wastewater from tanneries besides having toxic compounds also contain nutrients such as carbon, phosphorus, and nitrogen, which facilitate the rapid multiplication of microalgae. Currently, several researches search microalgae capable of growing in industrial effluents, exploiting the advantages of removing the nutrients present in these waters and producing biomass with high value added. The liquid effluents produced in tanneries for finished leather have essential nutrients for the growth of microalgae, but also some compounds that may restrict or hinder the growth of microalgae in this medium. Therefore, the present work has the objective to evaluate the growth of a microalgae consortium for the removal of phosphorus and ammonia from wastewater streams of a tannery processing wet-blue to finished leather with different photoperiods. Microalgae consortium was cultivated at two different compositions of mixtures of raw wastewater (R) and wastewater after secondary biological treatment (B): 50% of R + 50% of B, (50R50B) and 75% of R + 25% of B, (75R25B), in photoperiod of 24 hours and 12 hours of light, temperature of 25 °C and constant aeration. The growth of microalgae in the effluent and the removal of phosphorus, nitrogen and ammonia were monitored throughout the cultivation. The highest growth was achieved in the 24-hours condition with maximum biomass concentrations in the 75R25B effluent (1.40 g L-1) and phosphorus removal (97.94% for the 50R50B), nitrogen removal (71.53% for the 50R50B) and ammonia removal (100% for both effluent). © 2019 VGCT.

Microplastics, interacting with drought stress, have become threat to crops by altering soil environment. Currently, the effect of combined microplastic and drought stress on crop growth remain poorly understood. In this work, the mechanism of multi-stress responses was investigated under the exposure of polvinylchloride microplastic (PV) and drought (D) individually and in combination (DPV) on rice varieties Hanyou73 and Q280 through proteomics and metabolomic analysis. All treatments negatively affect chlorophyll content, antioxidant enzyme activities, rice grain composition, metabolome and proteomic profiling of both rice varieties. Full rice grain yield was decreased under all treatments except PV treatment in which it was increased in both rice varieties. DPV treatment shows the lowest grain yield and more adverse effects on metabolome by affecting glycerophospholipid metabolism, tryptophan metabolism and alanine, aspartate and glutamate metabolism. Soluble sugar contents were decreased in H73 but in Q280 increased by 159 % under DPV and 123 % in PV treatment, compared to their control group. The results from metabolomics illustrate that glycerophospholipid metabolism is commonly altered in both rice types under all treatments. PV and drought alone and in combination induce extensive alterations in proteomics of rice leaves especially impacting proteins related to binding, translation and photosynthetic process. The results reveal that PV and DPV treatments highly distort the abundance of metabolites and proteins in both rice types, demonstrating that microplastic toxicity effects on rice plants become more severe when combined with drought stress. © 2024 Elsevier B.V.

In this paper we focus on the sensor scheduling for dynamic state estimation among multiple processes. Multiple sensors transmit their measurements to the remote estimator via a shared wireless channel. Only a subset of sensors are allowed to transmit at each time. The objective of the scheduler is to maximize a linear combination of the terminal time estimation error covariances in a log-determinant sense. We develop conditions under which the objective is monotone and submodular. A submodularity-based greedy scheduling algorithm is proposed, and its performance bound is provided. Numerical examples are presented to illustrate the theoretical findings.

Selective methanol oxidation reaction (MOR) to value-added formate can maximize the input energy utilization for water electrolysis by replacing the high onset-potential and kinetics sluggish oxygen evolution reaction. However, to date only first-row 3d transition metal oxides present the capacity of selective MOR, motivating the design of new kinds of electrocatalysts to further enhance the MOR performance. Herein, we show amorphous Nb2O5 as an efficient electrocatalyst, for the oxidation of methanol to formate, with a low operating potential of 1.47 V vs. RHE to achieve industry-relevant current densities (>100 mA cm-2) with a Faraday efficiency of ~100%. We demonstrate, via operando Raman measurements, this superior electrochemical MOR activity originated from the in-situ induced short Nb-O bonds from the amorphous structure, while the crystalline Nb2O5 fails to generate this active site resulting in a poor activity. This work may provide valuable insight for developing novel transition metal oxides for MOR catalysts. © 2023, The Authors. All rights reserved.

Exploiting metal chalcogenide-based photocatalysts has fascinated researchers as a source of green hydrogen (H2) energy. Herein, we have designed a novel selenium-enriched NiSe1+x/ZIS (NiSexZ) photocatalytic system via a two-step hydrothermal and facile photo-deposition method. It was fascinating to conclude here that the NiSexZ photocatalytic system showed boosted H2 evolution results in comparison with other sulphur-enriched NiS1+x/ZIS (NiSxZ) and tellurium-enriched NiTe1+x/ZIS (NiTexZ). The optimized NiSe0.5Z composite exhibited a photocatalytic H2 evolution of 3.24 mmol g -1 h -1, a 9.8-fold increase over pure ZIS and it demonstrated an apparent quantum efficiency (AQE) of 2.06% via 420nm filter. Moreover, sulphur (S), selenium (Se), and tellurium (Te) synergistic active sites were exposed to promote H2 evolution reaction in this work. Given the significant advancements and commendable performance exhibited by the Se-Hads across the week bond, it is extremely probable that the NiSe1+x cocatalyst holds immense potential for the development of sophisticated photocatalytic materials. © 2024, The Authors.
