Summary: This study presents experimental results on the ohmic conductivity degradation of nanostructured anatase bridges under the long-term effect of direct current. The degradation is found to be irreversible and is likely caused by the capture of conduction electrons by deep traps in anatase nanoparticles. The analysis of voltage drops reveals a critical exponent for ohmic conductivity, which agrees well with the model data for percolation systems. The observed changes in the spectral density of conduction current fluctuations suggest the increasing contribution of blockages and avalanche-like breakdowns near the percolation threshold.

Summary: We improved the sensitivity of NO2 analyte by adjusting the width ratio of adjacent graphene oxide (GO) and reduced graphene oxide (rGO) layers using GO laser reduction technique. The reduction of GO led to a chemiresistive response to NO2, and an optimum GO/rGO width ratio achieved a chemiresistive response of 18.1% towards 100 ppm of NO2 with a limit of detection of 230 ppb. The enhanced chemiresistive response of GO/rGO sensors to NO2 physisorption was attributed to increased sorption energy and improved charge transfer at the GO/rGO interface area compared to fully reduced GO.

Summary: In this paper, LixCa(1-x)Cu3Ti4O12 (LCCTO) solid solutions were successfully synthesized and the doping effect of lithium on the properties of LCCTO ceramics was investigated. It was found that low concentrations of lithium (x < 0.05) inhibited grain growth, while higher concentrations of lithium promoted grain growth. The addition of lithium also significantly decreased the grain boundary resistivity of the ceramics. The relaxation times for grain dipoles and grain boundary dipoles were determined using the Havriliak-Negami equation.

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.
