Article Synopsis
- The study investigates how different oxygen levels in artificial seawater affect the corrosion of a high entropy alloy (HEA) called AlCoCrFeNi.
- It finds that lower oxygen levels lead to a significant increase in corrosion rates, with rates at 2.0 mg/L being 421 times higher than at 7.0 mg/L, and changes the corrosion type from pitting to uniform corrosion.
- The corrosion issue is primarily due to a thin passivation film in low oxygen conditions and the high reactivity of alloy elements like Al and Ni, suggesting that future designs should limit Al and cautiously include Ni to enhance corrosion resistance.
Swallowtail butterflies (Papilionidae) are a historically significant butterfly group due to their colorful wing patterns, extensive morphological diversity, and phylogenetically important position as a sister group to all other butterflies and have been widely studied regarding ecological adaption, phylogeny, genetics, and evolution. Notably, they contain a unique class of pigments, i.e.

Objective: To study the radiobiological characteristic of human nasopharyngeal carcinoma cell lines CNE1 and CNE2 and the changes in expression MRN (Mre11-Rad50-Nbs1) complex in the cell lines exposed to irradiation.
Methods: CNE1 and CNE2 were irradiated by a linear accelerator. Radiobiological characteristics were detected by colony assay and MTT assay.

Article Synopsis
- New negative pressure biopsy technology includes an automatic gun and specific puncture needle developed for better biopsy procedures.!
- In a study, renal biopsies were performed on 1136 cases resulting in a 99.9% success rate, with some cases experiencing gross hematuria.!
- The biopsy gun is user-friendly, boasts a higher success rate, and has fewer complications compared to traditional methods.!
Article Synopsis
- Thioacetamide was immobilized on silica gel to extract copper(II), lead(II), and cadmium(II) ions from water using the Mannich reaction.
- Effective extraction conditions, including optimal pH levels and desorption methods, were identified for each metal ion, enabling their determination through flame atomic absorption spectrometry.
- The adsorption capacities were significant, with the highest for lead(II), and the method was successfully applied to real water samples from various sources.
