“…The integrated energy system is generally composed of a variety of heterogeneous energy supply methods and a variety of energy units, and the requirements for information communication are far more complex than the single energy sys-tem. The intelligent integrated energy management platform is developed for the management and optimization of the integrated energy system, which is com-posed of related hardware and software systems [2].…”

Smart Integrated Energy System is a system that combines multiple energy sources, such as coal, oil, natural gas, electricity, and heat, through the use of cutting edge physical and information technologies, as well as innovative management models, in order to facilitate coordinated planning and efficient operation between energy subsystems, as well as collaborative management, interactive response, and mutual complementation. The platform can be constructed by using energy big data, 3D digital twin, multi-energy collaborative optimization and scheduling and intelligent operation. The platform furnishes data base and decision-making assistance for Integrated Energy services, al-lowing for comprehensive management applications of energy monitoring, operation scheduling, maintenance, charge management and customer service management, supplying energy production, transmission, consumption, and control throughout the process, and achieving efficient production, flexible control, and intelligent utilization of various forms of energy. The platform has the capability to create a comprehensive energy utilization system encompassing sources, grids, loads, and storage, thereby establishing the technical groundwork for advancing the comprehensive and extensive utilization of renewable energy.

Antibacterial Activity of ZnSe, ZnSe-TiO2 and TiO2 Particles Tailored by Lysozyme Loading and Visible Light Irradiation

et al. 2023

ZnSe, ZnSe-TiO2 microspheres and nanostructured TiO2 obtained by hydrothermal and sol–gel methods were tested against Staphylococcus aureus ATCC 25923 and Micrococcus lysodeikticus ATCC 4698 before and after lysozyme (Lys) loading. Morphological characterization of inorganic matrices and hybrid organic–inorganic complexes were performed by microscopy techniques (SEM, AFM and Dark Field Hyperspectral Microscopy). Light absorption properties of ZnSe, ZnSe-TiO2 and TiO2 powders were assessed by UV–visible spectroscopy and their ability to generate reactive oxygen species (•OH and O2•−) under visible light irradiation was investigated. Antibacterial activity of ZnSe, ZnSe-TiO2, TiO2, Lys/ZnSe, Lys/ZnSe-TiO2 and Lys/TiO2 samples under exposure to visible light irradiation (λ > 420 nm) was tested against Staphylococcus aureus and Micrococcus lysodeikticus and correlated with ROS photogeneration.

“…(2) the emission wavelengths from doped NCs can be modulated from ultraviolet to NIR wavelength region, accompanied by large Stokes shift, which can further enhance their application prospects in biological imaging; (3) doping transition metal ions into NCs can greatly extend their luminescence life, which can further expand their application in fluorescence lifetime imaging for inhibiting background fluorescence. To date, many research groups have studied the application of transition metal-doped NCs in bioimaging [20][21][22]. For the high resolution deep-tissue bioimaging, the probes should exhibit NIR emission and can be efficiently excited by multiphoton absorption (MPA) in the NIR wavelength range, especially in NIR-I (700-1000 nm), NIR-II (1100-1350 nm), NIR-III (1600-1870 nm) biological windows [23].…”

Due to their unique optoelectronic properties, doped semiconductor nanocrystals (NCs) are promising fluorescent probes for deep-tissue bioimaging applications. However, studies on the photophysical properties of cadmium-free doped NCs are scarce. In this study, we synthesized and studied the photophysical properties of one type of cadmium-free doped NCs (Cu: ZnInS/ZnS NCs), which exhibit near infrared-I (NIR-I) emission at 730 nm and long emission lifetime up to 1.38 μs. Femtosecond transient absorption spectra revealed a strong exciton coupling effect between the Cu2+ ions and the ZnInS/ZnS host, with a fast energy transfer time of ≈100 ps. More importantly, Cu: ZnInS/ZnS NCs exhibit efficient volume-normalized two- and three-photon absorption cross-sections in NIR-I (800–900 nm) and NIR-III regions (1600–1990 nm), with maximum values up to 6.9 GM nm−3 at 800 nm and 1.1 × 10−80 cm6 s2 photon−2 nm−3 at 1600 nm, respectively. This study can shed light on the exploration of novel environmentally friendly doped NCs for deep-tissue bioimaging applications.
