Article Synopsis
  • MXenes, which are 2D transition metal compounds, show potential for use in non-noble-metal catalysts for hydrogen evolution reactions by maximizing their large surface area.
  • This study introduces a composite material, Au-TiCO, created by synthesizing oxygen-functionalized TiCT MXene and adding gold nanoparticles, enhancing electron transfer and catalytic activity.
  • The results indicate improved catalytic performance with an overpotential of 62 mV, supported by electron interactions between Au NPs and MXene, as confirmed by advanced microscopy and theoretical calculations.

Article Synopsis
  • - Rhabdias kafunata is a parasitic nematode affecting toads, with its mitochondrial genome sequenced to understand its genetic structure, which is 14,068 bp long and contains 36 genes, including 12 protein-coding genes.
  • - The nucleotide composition of its mitochondria is biased toward adenine (A) and thymine (T), making up 75.5% of the genome, and the cox1 gene can be used for species identification due to its conservation.
  • - Phylogenetic analysis shows R. kafunata is part of the Rhabditidae family and is closely related to Litoditis marina and Caenorhabditis angaria, indicating its

Background: Urine sediment examination is a time-tested and non-invasive diagnostic tool. This study investigated the characteristics of urine sediment and its association with severity and renal outcomes in diabetic nephropathy (DN) patients.

Methods: A total of 201 biopsy-proven diabetic nephropathy patients (according to the pathological classification of diabetic nephropathy proposed by the Renal Pathology Society in 2010) who underwent manual urine sediment microscopic examination were included.

Article Synopsis
  • This study focused on creating copper oxide (CuO) using a microwave-assisted hydrothermal method and combining it with rare metal compounds to enhance the degradation of tetracycline (TC) in water.
  • The resulting composite material, ZnInS@CuO, demonstrated a high degradation efficiency of 95.8% for TC, significantly outperforming CuO and ZnInS alone due to improved electron-hole separation and charge transfer facilitated by the Z-scheme heterojunction structure.
  • Additionally, ZnInS@CuO showed good stability over multiple cycles and identified the sites of radical attack on TC, suggesting a promising strategy to improve photocatalytic materials for wastewater purification.

The characterization of the heterostructure active sites during the hydrogen evolution reaction (HER) process and the direct elucidation of the corresponding catalytic structure-activity relationships are essential for understanding the catalytic mechanism and designing catalysts with optimized activity. Hence, exploring the underlying reasons behind the exceptional catalytic performance necessitates a detailed analysis. Herein, we employed scanning electrochemical microscopy (SECM) to image the topography and local electrocatalytic activity of 1T/2H MoS heterostructures on mixed-phase molybdenum disulfide (MoS) with 20 nm spatial resolution.

Benzo[]pyrene is difficult to remove from soil due to its high octanol/water partition coefficient. The use of mixed surfactants can increase solubility but with the risk of secondary soil contamination, and the compounding mechanism is still unclear. This study introduced a new approach using environmentally friendly fatty acid methyl ester sulfonate (MES) and alkyl polyglucoside (APG) to solubilize benzo[]pyrene.

Aims: In diabetic kidney disease (DKD) patients, early-onset T2DM effects on renal disease severity and outcomes remain uncertain. Herein, we aim to investigate the clinicopathological characteristics and renal outcomes in DKD patients with early-onset T2DM.

Methods: 489 patients with T2DM and DKD were retrospectively recruited and classified as having early (age at onset of T2DM < 40 years) and late (age at onset of T2DM ≥ 40 years) T2DM onset, analyzing the clinical and histopathological data.

Background: Although extensive efforts have been paid to identify reliable predictors for renal outcomes of diabetic kidney disease (DKD) patients in type 2 diabetes mellitus (T2DM), there are still only a limited number of predictive factors for DKD progression. Increasing evidence reported the role of the overactivated complement system in the pathogenesis of DKD. Whether renal complement depositions are associated with renal outcomes of DKD in T2DM is of interest.

In recent years, thanks to the investigation of the in-depth mechanism, novel cathode material exploitation, and electrolyte optimization, the electrochemical performance of rechargeable Zn-based batteries (RZBs) has been significantly improved. Nevertheless, there are still some persistent challenges locating the instability of the Zn anodes that hinder the commercialization and industrialization of RZBs, especially the obstinate dendrites and hydrogen evolution reaction (HER) on Zn anodes, which will dramatically compromise the cycle stability and Coulombic efficiency. Therefore, various strategies with fundamental design principles focusing on the suppression of dendrite and the HER have been carefully summarized and categorized in this review, which are critically dissected according to the intrinsic mechanisms.

Introduction: As the most common complication of diabetes mellitus (DM), diabetic nephropathy (DN) was initially considered to begin with proteinuria preceding the progression of renal insufficiency. This clinical paradigm has been questioned in the late decades, as many DM patients without proteinuria have progressive renal insufficiency. However, the characteristics of nonproteinuric DN were not fully clear yet.
