Summary: To address the limitations of traditional diagnostic methods for Pheochromocytoma (PCC), a dual-targeting Surface-Enhancement Raman Scattering (SERS) cytosensor was developed to identify and detect PCC-CTCs from peripheral blood. The SERS signal export was achieved using Meta-iodobenzylguanidine (MIBG) and octreotide-2,2 ',2 '',2'-(1,4,7,10 -tetraazacyclo-dodecane-1,4,7,10-tetrayl) tetraacetic acid (DOTA) functionalized magnetic Fe3O4 and Ag-DTNB as capture probe and signal probe, respectively. The use of Ag nanocubes (AgNCs) as Raman active substrate enhanced the signal intensity of DTNB, enabling trace analyte detection. This study provided new insights into the accurate detection of PCC-CTCs.

Summary: In this study, three-dimensional Ag aerogel-supported Hg single-atom catalysts were used as an efficient SERS substrate for monitoring enhanced oxidase-like reactions. The effect of Hg2+ concentrations on the SERS properties of 3D Hg/Ag aerogel networks was investigated, and an optimized addition of Hg2+ resulted in specific enhancement. The formation of Ag-supported Hg SACs was confirmed using HAADF-STEM imaging and XPS measurement, and the oxidase-like catalytic mechanism of Hg/Ag SACs was revealed using DFT. This research provides a mild synthetic strategy for fabricating Ag aerogel-supported Hg single atoms with promising prospects in various catalytic fields.

Summary: TiO2 is a photocatalyst material that can produce green hydrogen through water splitting. Plasmon-enhanced photocatalysis, which utilizes visible and near-infrared regions, has been explored to extend the absorption wavelength range. Noble metal surfaces can provide hot electrons and holes for hydrogen production. Localized surface plasmon resonance (LSPR) plays a key role in accelerating electron transfer. This review comprehensively discusses the dynamics of hot carriers in plasmon for more efficient green hydrogen production.

Summary: Net zero emission/energy can be achieved by utilizing solar energy through a parabolic trough collector (PTC), and the effective design process and adjustable operating settings are crucial factors. A comparative study was conducted on the power output and hydrogen generation of a parabolic trough solar collector integrated with a Rankine cycle and an electrolyzer. CuO nanomaterials in the absorber demonstrated the highest thermal efficiency of approximately 79%, leading to improved hydrogen generation and heat transfer rate, compared to Al2O3 and Water-WO3 nanomaterials with lower thermal efficiencies of approximately 72% and 68% respectively.

Summary: Sustainable energy development is a globally important research area that requires effective design processes and sustainable energy sources. A study conducted experiments using a solar heating system with two-parabolic trough collectors (PTC) to operate a Rankine cycle-based fuel cell for hydrogen production. The results showed that by optimizing the heat transfer rate and using a flow rate of 0.38 kg/s for the heat transfer fluid (HTF), the system achieved a thermal efficiency of 82% and a heat gain of 27589 kW. Increasing the flow velocity of the HTF improved both the solar collector's efficiency and the electrical energy output for the fuel cell, resulting in higher hydrogen production rates. The study also conducted a preliminary cost analysis using the solar advisor model (SAM) to determine the electric cost of the integrated system.

Summary: Phthalate esters (PAEs) are commonly used plasticizers in the plastic industry. Due to the lack of chemical bonding with the polymer matrix, they can easily separate from plastic products and enter the environment. A global systematic review and meta-analysis found that river water and lake water are the most contaminated water sources with PAEs, with Nigeria being the most contaminated and China being the least contaminated. The majority of the population, including adults and children, are at risk of PAEs-related health issues.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
