“…The PDOS of the 2 p orbital of the O1 atom and the 3 d orbital of the Ti atom in the 3TiO 2 -graphene system are shown in Figure (f), and they overlap from −4 to −2 eV, which is consistent with the bonding of the 3TiO 2 -graphene system in Table . The doped graphene system has stronger electrical conductivity and stability and facilitates the gases’ adsorption compared to pristine graphene adsorption. − …”

Due to the high surface activity of metal atoms, it is difficult for doped metals to maintain long-term stability. Compared with other metal oxides, TiO2 graphene sensors have a higher sensing response and a larger specific surface area. However, there is currently no literature comparing and analyzing the effect of graphene-doped TiO2 on the adsorption performance of SF6 decomposition components. Therefore, this article investigated the adsorption performance of SF6 decomposition products: the distribution of SOF2 and SO2F2 on nTiO2 (n = 1,2,3)-doped graphene. In order to explore the interaction mechanism between gas molecules and these modified systems, their E ads, charge transfer, DOS, and PDOS were systematically studied. The doping of nTiO2 significantly improves the adsorption ability of graphene to gas molecules, discovers and enriches the online monitoring methods of GIS, and improves the engineering application value of GIS.

“…Unlike conventional ME power electronics research [47][48][49], the initial studies of ME power splitters focused on the conceptualization of the device prototype and rapidly expanded into the implementation. In 2023, inspired by the unique dual-port architecture of Rosen-type transformer, a ME power splitter from proof-of-concept to exploitable in the composite of ferrite/Rosen-type transformer was firstly opened up and implemented by our research group, the most salient feature of this attractive structure is the impedance gradient induced high isolation with simplified lumped topology [50]. Subsequently, investigations of theoretical modeling, configuration versatility and performance improvement have been our relatively recent endeavors.…”

Exploring low-frequency (LF) arbitrary power-splitting technologies to address the independent excitation issues of LF/VLF mechanical antennas (MA) with random distributions is challenging due to unidentified device construction and operation mechanism. In light of this, a device construction strategy for three-port magnetoelectric (ME) arbitrary power splitter in composite of ferrite/piezoelectric heterostructure, as well as theoretical model was developed. To validate the feasibility and effectiveness of the strategy, three size-tailored ME samples with length ratio of split PZT segments in 1:1, 2:1, and 3:2 were modeled, fabricated and comparatively characterized. Experimental results show that the achievable maximum power conversion efficiencies (PE) reach 52%, 71%, and 59% for three tailored ME samples, respectively, and as expected the power-splitting ratios are directly proportional to the square ratio of ME voltage coefficient (MEVC) from each port of the tailored ME samples, which are in coincidence with theory under desired operation stability and favorable experiment repeatability evaluated by uncertainties of 0.25854 V/cm Oe and 0.32979 V/cm Oe for each port. Therefore, a prediction of evolutionary tendency for arbitrary power splitter realization was expanded in view of our experimental observations, and a great flexibility for device future design and further optimization was also provided. Therefore, the presented LF power-splitting strategy paves the ways for arbitrary power splitter realization and enriches the multi-functional ME power electronics families, as well as enables potential applications for efficient excitations of MAs in high-permeable military underwater and civilian emergency rescue distribution long-wave communication system for practical scenarios of submarine, underground railways, tunnels and collapsed residential buildings.
