Bioretention systems are widely used for stormwater management due to their ability to retain and purify runoff; however, their nutrient removal performance, particularly for nitrate (NO-N), remains inconsistent. To address this limitation, this study proposed an integrated approach that incorporated a novel polyurethane-biochar crosslinked material (PCB) into the filler soil, along with a zero-valent iron (ZVI) amended internal storage layer. PCB is a porous polymer sponge that has been demonstrated in previous studies to possess a high water holding capacity and strong ion exchange ability.

However, the response mechanism of arsenic (As) dynamics in sediments to these changes remains unclear. In this study, we employed high-resolution techniques to investigate the seasonal dynamics of As at the SWI in aquaculture-impacted lake zones, systematically analyzing its mobilization pathways and associated driving mechanisms.

Mixed infection refers to the presence of multiple strains within one host, while heteroresistance denotes the coexistence of drug-susceptible and drug-resistant strains or genotypes. Mixed infections and heteroresistance with can complicate drug resistance diagnosis, treatment options, and transmission inference. We conducted a population-based genomic epidemiological study of multidrug-resistant tuberculosis (MDR-TB) in Shanghai, China, between January 1, 2005, and December 31, 2018, to evaluate the prevalence and impact of mixed infection and heteroresistance on MDR-TB diagnosis and treatment outcomes.

This study simultaneously investigated the seasonal variation characteristics of P and W in sediments in Meiliang Bay, China. The results indicated that seasonal variations in pH, dissolved oxygen (DO), and temperature (T) at the sediment-water interface influenced the P and W composition as well as their release from sediments.

2D polymeric fullerene scaffolds, composed of covalently bonded superatomic C nanoclusters, are emerging semiconductors possessing unique hierarchical electronic structures. Hitherto their synthesis has relied on complex and time-consuming reactions, thereby hindering scalable production and limiting the technological relevance. Here, the study demonstrates a facile electrochemical exfoliation strategy based on the intercalation and expansion of a layered fullerene superlattice, to produce large size (≈52.

The interaction of atomic orbitals at the interface of perovskite oxide heterostructures has been investigated for its profound impact on the band structures and electronic properties, giving rise to unique electronic states and a variety of tunable functionalities. In this study, we conducted an extensive investigation of the optical and electronic properties of epitaxial NdNiO synthesized on a series of single-crystal substrates. Unlike nanofilms synthesized on other substrates, NdNiO on SrTiO (NNO/STO) gives rise to a unique band structure featuring an additional unoccupied band situated above the Fermi level.

It is well known that aquaculture can alter the microenvironments of lakes at sediment-water interface (SWI). However, the main mechanisms underlying the effects of aquaculture activities on arsenic (As) transformations are still unclear. In this context, the present study aims to investigate the variations in the sediment As contents in Yangcheng Lake, as well as to assess its chemical transformations, release fluxes, and release mechanisms.

Background: Isoniazid-resistant, rifampicin-susceptible tuberculosis (Hr-TB) globally exhibits a high prevalence and serves as a potential precursor to multidrug-resistant tuberculosis (MDR-TB). Recognizing the spatial distribution of Hr-TB and identifying associated factors can provide strategic entry points for interventions aimed at early detection of Hr-TB and prevention of its progression to MDR-TB. This study aims to analyze spatial patterns and identify socioeconomic, demographic, and healthcare factors associated with Hr-TB in Shanghai at the county level.

Sulfate concentrations in eutrophic waters continue to increase; however, the transformations of arsenic (As) in sediments under these conditions are unclear. In this study, we constructed a series of microcosms to investigate the effect of algal degradation on As transformations in sediments with high sulfate concentrations. The results showed that both the elevated sulfate levels and algal degradation enhanced the release of As from sediments to the overlying water, and degradation of algal in the presence of elevated sulfate levels could further contribute to As release.
