In order to study the effects of oxalic acids on plant growth and Pb accumulation in different parts of the plants of intercropping and , pot experiment was conducted to investigate the changes of oxalic acid contents of the plants and Pb accumulation through exogenous oxalic acid addition (0, 5, 25 and 50 mmol kg). The results showed the root biomass of intercropped and total biomass of increased by 3.22 folds and 2.97 folds with 5 mmol kg oxalic acid treatment. The oxalic acid contents of shoots and root secretions decreased by 86.5% and 44.3%, respectively. The BCF (bio-accumulation factor) and TF (translocation factor) of intercropping reduced under 25 - 50 mmol kg oxalic acid treatments. There were relationships between exogenous oxalic acid treatment concentrations and oxalic acid contents of shoots, root secretions. The Pb contents of shoots of and were related to exogenous oxalic acid additions and oxalic acid contents of shoots. In general, 5 mmol kg oxalic acid treatment, that can improve plant growth of intercropped and , which Pb translocation and accumulation of were promoted, whereas Pb accumulation of was inhibited with 25 - 50 mmol kg concentrations addition. This study will provide a basis for promoting the application of phytoremediation techniques and efficient crop production in heavy metal contaminated areas.

In this study, phosphoramide compounds were successfully synthesized a series of reaction transformations from P(O)H compounds. The process began with the formation of P-Se-Ar bonds, facilitated by the synergistic effect of phenylboronic acid, selenium, and appropriate ligands in the presence of copper. Following this, nucleophilic substitution reactions with amine compounds were conducted to create P-N bonds.

Article Synopsis
- A study explored salvage chemotherapy using capecitabine plus oxaliplatin (XELOX) for gastric cancer patients who couldn't tolerate or were resistant to cisplatin, but it was halted due to low patient enrollment.
- 12 patients participated, revealing a disease control rate of 90% and a response rate of 30%, with median progression-free survival of 4.2 months and overall survival of 7.1 months.
- Common severe side effects included fatigue and low potassium levels, but there were no treatment-related deaths, suggesting XELOX might be beneficial for these patients.

Ferrous oxalate (FeCO)-based composite has been recognized as an eminent catalyst for Cr(III)-ethylenediamine tetraacetic acid (Cr(III)-EDTA) decomplexation. However, their practical application has been limited by low cycling capacity and an ambiguous mechanism. In this research, a composite catalyst consisting of biotite loaded with nano FeCO (CFS90) was prepared directly from iron-containing silicate tailing.

Abundant polyphenols in Flos Sophorae Immaturus tea (FSIt) exhibited xanthine oxidase (XO) inhibitory activity. However, the XO inhibitory activity of FSIt was closely related to the processing methods. Herein, organic acids were employed as catalysts for polyphenol conversion during heat treatment and applied to enhance the XO inhibitory activity of FSIt; the potential mechanisms were clarified by polyphenols degradation and conversion analysis, omission experiment, and interaction assay.
