γ-MnO precoated lead (Pb)-based anodes have shown high initial activity in heavy-metal pollution reduction and production improvement for zinc electrowinning in laboratory. However, the accumulated impurity ions (M) in industrial MnO-precursors restrict its industrial application. Herein, the heterostructure-induced rich oxygen-vacancies for M-MnO and its higher activity (Pb/Co-MnO>Pb/Ni-MnO>Pb/Fe-MnO ≈Pb/Cu-MnO>Pb/MnO) was reported.

Metabolic reprogramming is pivotal in cancer stem cell (CSC) self-renewal. However, the intricate regulatory mechanisms governing the crosstalk between metabolic reprogramming and liver CSCs remain elusive. Here, using a metabolic CRISPR-Cas9 knockout screen, we identify ATP6V1D, a subunit of the vacuolar-type H-translocating ATPase (V-ATPase), as a key metabolic regulator of hepatocellular carcinoma (HCC) stemness.

Article Synopsis
  • * Researchers observed a unique redshift phenomenon in the far ultraviolet region when examining 14 inorganic anions, where absorption peaks below 200 nm shifted as pathlength and concentration increased.
  • * The results indicate that this redshift is caused by stray light in the spectrophotometer, highlighting the need for methodological and instrumental improvements to ensure accurate spectral analysis in scientific research.

The dysregulation of membrane protein expression has been implicated in tumorigenesis and progression, including hepatocellular carcinoma (HCC). In this study, we aimed to identify membrane proteins that modulate HCC viability. To achieve this, we performed a CRISPR activation screen targeting human genes encoding membrane-associated proteins, revealing TMX2 as a potential driver of HCC cell viability.

  • B4GALNT1 is found to be overexpressed in hepatocellular carcinoma (HCC) and correlates with worse patient outcomes, contributing to tumor stemness and aggressiveness.
  • Various experimental methods, including immunohistochemistry and flow cytometry, were used to demonstrate B4GALNT1's role in promoting key cancer-related behaviors, such as cell growth, migration, and invasion.
  • The study identifies a specific signaling pathway involving B4GALNT1, integrin α2β1, and the FAK/PI3K/AKT cascade as a possible target for HCC treatment, with Ophiopogonin D showing promise in disrupting this pathway.

In order to accurately obtain photometric information of high concentration SO and other substances in the process industry, the spectroscopy behavior of SO, S, Ni and Cu in air and nitrogen atmosphere was compared based on the UV-visible spectrophotometer with a nitrogen replacing the oxygen. Different from Ni and Cu, the accuracy of SO and S in the ultraviolet region was effectively improved by using a nitrogen atmosphere (P detection results were regressed within the limited standard range, RE < 5%). The nitrogen atmosphere suppressed the additional light attenuation caused by its absorption of ultraviolet rays by isolating oxygen and was also reflected in the decrease in the degree of red shift of the characteristic wavelength for SO with increasing concentration.

  • Absorption spectra are vital for analyzing chemicals, and understanding their characteristics can enhance the development of analytical models.
  • The study explored the electronic excitation properties of phosphate anions using time-dependent density functional theory (TD-DFT) and noted that red shifts in maximum absorption wavelengths occur with increasing concentration and optical path length due to changes in hydrogen bonding.
  • Results emphasized that the optical path length significantly affects absorption characteristics, providing insights for improving both qualitative and quantitative analyses of phosphate anions and potentially other chemicals through absorption spectroscopy.

Lead pollution precaution caused by lead-based anode corrosion is a hot and challenging issue for zinc electrowinning. A novel functional lead-based anode (MnO pre-coated anode-MPA) was precisely fabricated and its long-term performances were studied compared with typical Pb-1%Ag anode (TPA). Results indicated that MPA posed excellent effects on synergistic inhibiting lead dissolution and reducing hazardous pollutants generation, and decreasing the lead content of zinc products by 81%.

  • * Results indicated that Mn enhances the oxygen evolution reaction (OER) at concentrations of 1 and 3 g/L but causes instability and reduced efficiency at 10 g/L due to changes in oxide layer properties.
  • * The mechanism behind anode slime generation shifts with different Mn levels, with lower concentrations leading to smaller slime particles, while higher concentrations improve settling performance, suggesting that controlling Mn levels could offer a cleaner way to manage anode slime production.

Cr(VI) is a powerful oxidant and is capable of oxidizing most of the organic materials. Therefore, it is possible for Cr(VI) to oxidize the polymeric resins and change the sorption properties of the resins on the removal of Cr(VI) from wastewater by anion exchange. In this study, three polystyrene resins (D201, D202, and D301) with different functional groups (-N(+)(CH3)3, -N(+)(CH3)2(C2H4OH), and N(CH3)2) were assessed on oxidation stability for Cr(VI) removal from wastewater in fixed-bed column experiments.

A novel Ni-Fe bimetal with high dechlorination activity for 4-chlorophenol (4-CP) was prepared by ball milling (BM) in this study. Increasing Ni content and milling time greatly enhanced the dechlorination activity, which was mainly attributed to the homogeneous distribution of Ni nanoparticles (50-100 nm) in bulk Fe visualized by scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS) with image mapping. In comparison with the Ni-Fe bimetal prepared by a chemical solution deposition (CSD) process, the ball milled Ni-Fe bimetal possessed high dechlorination activity and stability before being used up.
