Abstract:
... Recycling phosphorus (P) from waste is an effective way to alleviate resource and environmental pollution due to excessive phosphate consumption. In order to better understand the feedback of P cycle to waste recycling methods, a P waste feedback model was built and was then used to predict P waste generation, recycling, loss and phosphate consumption in China under several P management scenarios. ...

Abstract:
... Partially dephosphorylated bovine beta-casein has great potential to become a novel infant formula base in the future. At present, there are few studies on the self-association properties of partially dephosphorylated bovine beta-casein, which are very essential and important for its processing and application. This study investigated the self-association properties and physical stability of parti ...

Abstract:
... Many studies have examined per- and poly-fluoroalkyl substances (PFASs) in human blood. However, the distribution of PFASs in human blood remains not well known, especially for perfluorooctane sulfonate (PFOS) precursors. In this study, human blood samples (n = 162) were collected from general Chinese population, and then the isomer-specific partitioning of PFASs between human plasma and red blood ...

Abstract:
... Lead (Pb) contamination is one of the most significant exposure hazards to human health. Contaminated soil particles may be eroded and transferred either to the atmosphere (<10 μm) or to streams; or they may be incidentally ingested (<200 μm). Among strategies for the long-term management of this risk, one of the most cost-effective is the reduction of Pb mobility and bioavailability via amendment ...

Abstract:
... We applied an integrated target, suspect, and non-target screening strategy to analyze known and unknown organophosphate esters (OPEs) in 107 foodstuffs collected from Nanjing City, China, in 2020. Twelve out of 19 target OPEs were detectable in at least one of the analyzed samples. Among the nine food categories, meat samples were contaminated the most severely with a mean ΣOPEs concentration of ...

Abstract:
... Organophosphorus pollutants (OPs), which are compounds containing carbon‑phosphorus bonds or phosphate derivatives containing organic groups, have received much attention from researchers because of their persistence in the aqueous environment for long periods of time and the threat they pose to human health. Heterogeneous photocatalysis has been widely applied to the removal of OPs from aqueous s ...

Abstract:
... Antibiotic pollution imposes urgent threats to public health and microbial-mediated ecological processes. Existing studies have primarily focused on bacterial responses to antibiotic pollution, but they ignored the microeukaryotic counterpart, though microeukaryotes are functionally important (e.g., predators and saprophytes) in microbial ecology. Herein, we explored how the assembly of sediment m ...

Abstract:
... Despite being an effective and attractive functional strategy for aqueous phosphorus (P) removal, the use of zero valent iron (ZVI) biochar composites has been severely impeded by rapid self-erosion. We describe a new approach for extending the lifespan of Fe-rich sludge-derived ZVI biochar composites via CaCl₂ modification. Preliminary results showed that composites obtained at 900 °C without mod ...
... Pseudomonas fragi and Escherichia coli are considered as common colonizers of fresh and spoilage meat, where they tend to live in the proximity. In this study, we primarily tested interplay patterns between different isolates of these two species in two-by-two combinations grown on stainless steel surfaces as dual-species biofilms. Results showed that these two species presented competition as maj ...
... Organophosphate esters (OPEs), which are frequently used as flame retardants and plasticizers in versatile products, are readily released to the external environment. Although workers at municipal waste incineration plants may be extensively exposed to OPEs, only scarce health monitoring and risk assessments have been conducted in this population. In this study, we investigated the levels of eight ...

Abstract:
... As an energy-efficient and eco-friendly technique, capacitive deionization (CDI) has shown great potential for uranium (U(VI)) capture recently. However, extracting U(VI) with high kinetics, capacity and selectivity remains a major challenge due to the current surface active sites-based material and co-existing ions in aqueous solution. Here we rationally designed a layered 2D/2D niobium phosphate ...

Abstract:
... Sodium-ion batteries, featuring resource abundance and similar working mechanisms to lithium-ion batteries, have gained extensive interest in both scientific exploration and industrial applications. However, the extremely sluggish reaction kinetics of charge carrier (Na⁺) at subzero temperatures significantly reduces their specific capacities and cycling life. Herein, this study presents a novel h ...

Abstract:
... Tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) is a commonly used organophosphate-based flame retardant and can bio-accumulate in human tissues and organs. As its structure is similar to that of neurotoxic organophosphate pesticides, the neurotoxicity of TDCIPP has raised widespread concerns. TDCIPP can increase neuronal apoptosis and induce autophagy. However, its regulatory mechanism remains un ...
... The naive detection of scheduled H drug oxytocin is a vital requisite, owing to its deleterious impact on societal affluence prompted by unconstrained usage. Therefore, a reliable, cost-effective, and quick-to-respond analytic technique for this drug is in ample demand. In this work, we report electrochemical detection of oxytocin employing novel nitrogen, phosphorus co-doped coke-derived graphene ...
... The external acid environment of cancer cells is different from that of normal cells, making a profound impact on cancer progression. Here we report a simple poly-l-lysine-modified graphene field-effect transistor (PLL@G-FET) for in situ monitoring of extracellular acidosis around cancer cells. PLL is a well-known material with good biocompatibility and is rich in amino groups that are sensitive t ...
... The hypoxic tumor microenvironment and photodynamic therapy (PDT)-aggravated hypoxia compromise the anticancer efficacy of chemotherapy, immunotherapy, and PDT. Thus, sophisticated nanomedicines that can activate their anticancer capability in situ in response to specific stimuli need to be developed. This study aimed to construct a hybrid nanomedicine that activated chemotherapy by inducing hypox ...
... Icariin, the most effective bioactive component in Epimedium, is also the index component of Epimedium quality control in Pharmacopoeia. It was a very attractive approach for bioconversion from epimedin C to icariin. However, its potential was impeded by poor stability and non-recyclable properties of free enzymes. In this study, we have fused the linker (4LP) to α-L-rhamnosidase BtRha and success ...

Abstract:
... A novel, simple and high-sensitivity gas chromatography-tandem mass spectrometry (GC-MS/MS) method combined with external calibration was developed for the qualitative and quantitative determination of penicillin G residues in poultry tissues and pork. Samples were extracted by an ASE 350 apparatus with 0.2 mol/L phosphate buffer solution (pH 8.0) and purified on HLB solid-phase extraction (SPE) c ...
... Fe/S-bearing erdite flocculant has been proven to be effective in the precipitation of heavy metals from real electroplating wastewater, with the only drawback being the huge production of sludge. This sludge was rich in Fe/S/Zn/Cu/Ni and refractory to be recycled due to the extractant pollution by free Fe and the dissolution of sulphide. Herein, a multistep separation method was developed to diss ...
... Organophosphosphorus pesticides (OPs) are widely used as insecticides in agriculture. Human exposure to OPs has been linked to adverse effects including poorer child neurodevelopment, reduced birth weight, altered serum hormone levels, and reduced semen quality. We measured six OP dialkyl phosphate (DAP) metabolites [three dimethyl alkylphosphates (DMs) and three diethyl alkylphosphates (DEs)] in ...
