Summary: This paper provides a review of the inductively coupled plasma reactive ion etching (ICP-RIE) method for silicon carbide etching. The experimental results show that the addition of O-2 and changes in RIE and ICP power have an impact on the etching rate of the Cr mask and the selectivity of SiC/Cr etching. SiC, with its attractive properties, holds great potential benefits for advances in submicron semiconductor processing technology.

Summary: Arsenic speciation analysis was conducted on solid canned tuna samples, which were stored in oil and brine, using IC-ICP-MS. The method was optimized and validated, and the extraction of arsenic species was performed using (NH4)(2)CO3 at pH 10.5. The analysis showed that the total arsenic levels in the samples exceeded the limits set by Brazilian sanitary standards, but the major species detected was the non-toxic arsenobetaine.

Summary: Dissolved organic matter (DOM) is crucial in controlling the solubility and reactivity of trace metals in the environment. However, understanding the mechanisms of metal-DOM complexation has been challenging due to the complex mixture of organic compounds in DOM. In this study, a quantitative method using liquid chromatography with online inductively coupled plasma mass spectrometry (LC-ICP-MS) was developed to fractionate and detect organic-metal complexes. The method demonstrated high accuracy in quantifying the concentrations of organic-metal complexes and was used to investigate the effects of different stationary phases on the recovery and separation of trace metals in natural organic matter. It also revealed distinct metal-DOM speciation in oxidized and reduced soils. This method provides a valuable tool for advancing our understanding of metal-organic complexation in the environment.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: The study developed a split aptamer-based sandwich-type ratiometric biosensor for the detection of 17 beta-estradiol (E2) using photoelectrochemical and electrochemical assays. The biosensor utilized split aptamer fragments to recognize E2 and trigger a hybridization chain reaction, resulting in the production of double-stranded DNA labeled with CdTe quantum dots. This DNA complex was able to sensitize CdTe quantum dots and generate response signals for E2 detection. The developed biosensor demonstrated high sensitivity and accuracy with two linear ranges and low detection limits.
