Summary: This study synthesized and characterized three different nanocomposite materials, including silver and zinc oxide nanoparticles modified reduced graphene oxide (rGO), and rGO modified with both silver and zinc oxide nanoparticles. These materials were characterized using XRD, FTIR, TGA, Raman spectroscopy, SEM, and TEM techniques. The electrochemical responses of these materials towards the standard ferrocyanide/ferricyanide [Fe(CN)6]3-/4- redox system were investigated using CV and EIS techniques. The results showed that ZnO modified rGO exhibited excellent electrochemical performance, attributed to the high surface area of ZnO, providing a larger electrode/electrolyte interface and more sites at the electrolyte-ZnO interface.

Summary: The interaction between carbon nanotubes (CNTs) and graphene oxide (GO) was studied experimentally and computationally. It was found that the addition of GO can effectively improve the dispersibility of CNTs. The epoxy group and hydroxyl group have a significant impact on the dispersibility of CNTs. The dispersion effect of GO on ac-CNT is more pronounced, and the contact area between GO and CNT has a significant influence on the interaction.

Summary: In this study, a high-sensitivity pH sensor was developed using a functionalized single-wall carbon nanotube graphene (FSWCNT/G) composite. The sensor consisted of Cr/Au electrodes and FSWCNT/G sealed in a PDMS microchannel on a glass substrate. The fabricated composite sensor exhibited superior performance compared to a pristine graphene sensor, as confirmed by field-effect transistor (FET), linear sweep voltammetry (LSV), and response time measurements. The composite nanosensor demonstrated a high potentiometric gradient of 98.75 mV/pH within the pH range of 4-10 and showed potential for label-free cancer cell detection with a concentration detection range of 5 x 106 to 2.5 x 105 cells/mL.

Summary: Aqueous supercapacitors are considered promising for commercial energy storage devices due to their safety, low cost, and environmental friendliness. However, the challenge of achieving both long electrode lifespan and qualified energy-storage property has hindered their practical application. In this study, an electrode-electrolyte integrated optimization strategy is developed to meet real-life device requirements. By optimizing the nanomorphology and surface chemistry of the tungsten oxide anode, along with the design of a hybrid electrolyte, record-breaking durability and stable operation under extreme conditions are achieved. These results demonstrate the possibility of replacing commercial organic energy storage devices with aqueous counterparts for various daily applications.

Summary: Electrochemical analysis has emerged as a novel method for plant analysis, allowing the collection of signals related to electrochemically active substances and enabling plant species identification. Moreover, these signals can be utilized for studying plant phylogeny. In this study, electrochemical fingerprint patterns of Malvaceae leaves were obtained using an established methodology, and after processing, the fingerprints exhibited distinct differences. Three different recognition models were employed for analyzing the electrochemical fingerprints, with linear support vector classification achieving high accuracy in species identification when combining the signals collected in different buffer solutions. Additionally, the collected fingerprints were utilized for phylogenetic investigation, resulting in the clustering of 18 species into three groups, with species from the same genus clustered together. The obtained dendrogram from electrochemical fingerprinting was compared with morphological and complete chloroplast genome-based results.

Summary: Catalytic ozonation is a technique that uses active free radicals generated by ozone degradation to mineralize organic matter in water. It can be divided into homogeneous catalytic reactions using metal ions as catalysts and heterogeneous catalytic reactions using solid catalysts. Heterogeneous catalytic ozonation has advantages such as easy recovery, lower cost, higher activity, and improved mineralization rate compared to homogeneous catalytic ozonation.

Summary: The present study focused on using phospholipid fatty acid (PLFA) technology to investigate the rhizosphere soil microorganisms of Minghui 86 (MH) and Yangdao No.6 (YD) rice at different growth stages. The results showed that the rhizosphere soil microorganisms of MH and YD had distinct sensitivities to exogenous phosphorus and had a certain inhibitory effect on rice enhancement. The sensitivity of rice root soil microorganisms to exogenous phosphorus also varied in different growth stages of rice. Bacteria were the dominant microorganism in the soil microbial community of rice roots, and the addition of exogenous phosphorus had a certain impact on the structure of the soil microbial communities. Through analyzing the microbial community characteristics, the study provided further understanding of the effect of exogenous phosphorus on the microbial community characteristics of rice rhizosphere soil and its impact on ecological functions.

Summary: With the increase in heat power density in modern integrating electronics, there is an urgent need for high thermal conductivity thermal interface materials (TIM) to fill the gaps between heat source and heat sinks. Graphene-based TIMs have attracted attention due to the high thermal conductivity of graphene nanosheets. In this study, a novel strategy for enhancing the through-plane thermal conductivity of graphene papers by in situ depositing AgNWs on graphene sheets (IGAP) was proposed. The IGAP exhibited greatly enhanced heat dissipation performance compared to commercial thermal pads.
