Summary: In this study, a fluid-solid acoustic one-way coupling calculation model is established to investigate the combustion process of energetic materials in a closed bomb. The model is validated by experiments. The results show that the maximum peak sound pressure increases exponentially with an increase in loading doses or gas pressure. The combustion coefficient of the energetic materials has little effect on the combustion noise in the closed bomb. Thicker shell reduces the combustion noise of energetic materials and increases the range of reduction.

Summary: Metal-oxidizer nanocomposites have gained attention as potential gas-generating energetic materials that can replace or enhance CHNO compounds in certain applications. Experimentalists have used enclosed chambers to ignite metal-based energetic materials and report pressures. However, direct comparison of the reported pressures is difficult due to differences in chamber volume and mass. A parameter proportional to the released energy is proposed to harmonize experimental data, and calculations suggest that some nanothermites and ammonium nitrate-based energetic materials have achieved their theoretical performance levels. Furthermore, the calculations show that ammonium nitrate is a superior oxidizer compared to ammonium perchlorate.

Summary: The development of microbial fuel cells based on electro-catalytic processes is a new and sustainable approach to energy systems. Microbial fuel cells use microorganisms to transform chemical energy from renewable organic fuels and reduce pollution. However, not all microorganisms can generate sufficient energy. In this study, we evaluated the feasibility of using Rhizobium anhuiense as a catalyst for microbial fuel cells and found that using menadione as a mediator resulted in the best performance with an open circuit potential of 0.385 mV, maximal power density of 5.5 mu W/cm(2), and anode current of 50 mu A/cm(2) at 0.35 mV.

Summary: This review discusses the development of microbial biofuel cells and how similar principles apply to bioelectronic device development. Microorganism-based amperometric biosensors, with their low specificity, can be used to design microbial biofuel cells that can consume a wider range of chemical fuels. Charge transfer efficiency is a major challenge in biofuel cell development, which can be improved using nanomaterials and specific redox mediators. Additionally, the biocompatibility of conducting polymers with microorganisms is explored, including ways to modify cell-walls/membranes and improve charge transfer efficiency for biofuel cell design.

Summary: ZnO nanostructures with different morphologies and particle sizes were evaluated and applied for the development of an immunosensor. The nanostructures included spherical polydisperse structures, compact rod-like spherical structures, and rod-shaped particles. These ZnO nanostructures were mixed with Nafion solution and drop-casted onto screen-printed carbon electrodes, followed by immobilization of prostate-specific antigen (PSA). The affinity interaction of PSA with monoclonal antibodies against PSA was evaluated using the differential pulse voltammetry technique. The detection and quantification limits for anti-PSA were determined for different ZnO nanostructures.

Summary: Biomarkers are crucial in providing information about cancer and other diseases. Molecularly imprinted polymers (MIPs) have recently been used in analytical systems to detect cancer biomarkers, such as prostate cancer (PSA), breast cancer (CA15-3, HER-2), ovarian cancer (CA-125), hepatocellular carcinoma (AFP), and small molecule cancer biomarkers (5-HIAA and neopterin). The determination of low concentrations of these biomarkers in complex matrices is challenging, but MIP-based biosensors have been employed for assessment. This article provides an overview of the MIP-based sensor creation principles, analytical signal determination methods, and suitable materials for each biomarker through comparing and discussing the results of reviewed biosensors.

Summary: Ag/AgCl-based reference electrodes are widely used in electrochemical biosensors and bioelectrochemical devices. However, the large size of standard reference electrodes poses challenges when working with low-volume samples. This study presents a procedure to incorporate polyacrylamide hydrogel as a semipermeable junction membrane in Ag/AgCl reference electrodes, creating disposable, reproducible, and scalable membranes suitable for design. Experimental results demonstrate the efficacy of the home-built electrodes, which offer low potential deviation, long shelf-life, good stability, low cost, disposability, and high response rate, making them suitable for applications involving intense dyes or toxic compounds.

Summary: This study aimed to design an electrochemical sensor for the detection of Listeria monocytogenes using platinum and screen-printed carbon electrodes modified by molecularly imprinted polymer (MIP). The performance of MIP and non-imprinted polypyrrole (NIP)-modified electrodes was evaluated using pulsed amperometric detection. The results showed that the most effective extraction solution for removing bacteria and achieving a sensitive and repeatable sensor design was the proteolytic enzyme trypsin. The MIP-Ppy/SPCE sensor had a LOD of 70 CFU/mL and a LOQ of 210 CFU/mL, with a linear range from 300 to 6700 CFU/mL.

Summary: This study separated the total population of human skeletal muscle-derived mesenchymal stem/stromal cells (SM-MSCs) into different subpopulations using scanning electrochemical microscopy (AC-SECM) and evaluated their redox changes and myogenic differentiation potential. The results showed that the CD56(+) and CD56(-) subpopulations had different redox activities and myogenic differentiation potential, indicating that the total population of human SM-MSCs is heterogeneous and unevenly responsive to extracellular stimuli.

Summary: This study investigated the mechanism of interaction between SCoV2-S protein and specific antibodies using molecular dynamics, revealing that the formation of immune complexes occurs in two stages. By applying a two-step binding model for kinetic analysis, more precise determination of interaction rate constants was achieved compared to the 1:1 Langmuir binding model. These findings provide deeper insights into the formation of antigen-antibody immune complexes and offer a new approach for evaluating antibody affinity towards antigens.

Summary: Some drugs classified as persistent organic pollutants (POPs) cannot be efficiently removed by routine wastewater treatments. A combination of electrocatalysis and a sulfate-based advanced oxidation process via peroxymonosulfate activation has been proven to be an efficient and non-selective method for removing POPs. Perovskites, specifically calcium copper titanate (CCTO), were evaluated as electrode materials due to their unique structural properties and high chemical stability. Through fabrication of porous CCTO anodes with different percentages of polymethyl methacrylate (PMMA), it was found that the CCTO-30 anode exhibited the highest performance in terms of CuO phase amount, defect percentage, oxidation-reduction peak, and resistance. By using CCTO-30 as anodes in a beaker with PMS, paracetamol was completely decomposed due to copper catalytic cycle activation, leading to the generation of radicals and non-radicals that selectively remove paracetamol.
