Abstract: The present invention discloses an embedded hydrothermal-resistant NiSn—CS nano-catalyst and a preparation method therefor and use thereof. The method includes the following steps: firstly dissolving a Ni salt, a Sn salt and chitosan to form a sol solution; and then removing a solvent from the sol solution to obtain a gel, and subjecting the gel to carbonization treatment to obtain the embedded hydrothermal-resistant NiSn—CS nano-catalyst; wherein temperature of the carbonization treatment is 400° C. to 600° C., and duration of the carbonization treatment is 1 to 4 hours. The embedded hydrothermal-resistant NiSn—CS nano-catalyst prepared by the present invention significantly improves the dispersion of NiSn catalytic active sites and the stability of the structure and activity in hydrothermal environments.

Abstract: The present invention relates to a nitrogen-doped carbon-wrapped nickel catalyst for synthesis of higher alcohols by assembly of bioethanol and a preparation method therefor. The preparation method includes the following steps: S1, subjecting a soluble nickel salt and polyacrylamide to stirring with water, completely dissolving and then drying to obtain a precursor, where a molar ratio of the soluble nickel salt to polyacrylamide is 1:(0.5-8); and S2, subjecting the precursor to pyrolysis in an inert atmosphere at 300° C.-800° C. for 1-6 hours to obtain the nitrogen-doped carbon-wrapped nickel catalyst. The catalyst prepared by the method of the present invention has an active phase with high dispersity which enables synthesis of higher alcohols by efficient assembly of small molecules, and has relatively high stability which can still maintain high conversion rate and high yield for organic phase after 10 times of repeated use.

Abstract: A wireless communication method and system enabling dynamic multi-path data transmission and reception across heterogeneous radio access networks. The method includes selecting between sequential, concurrent, or redundant multipath transmission strategies based on real-time measurements of link quality parameters, including signal-to-interference-plus-noise ratio (SINR), reference signal received power (RSRP), delay, and spectrum availability. The system further enables adaptive transmission power control, modulation scheme selection, and carrier configuration based on physical layer feedback, minimizing interference and optimizing spectral efficiency. Peer-to-peer communication between terminals is supported without base station mediation, reducing RAN load. Multi-base station connectivity is enabled, allowing terminals to simultaneously transmit through multiple nodes and aggregate at the core network.

Abstract: The invention overcomes the constraints imposed by conventional wireless communication standards by introducing a physical-layer optimized architecture that decouples transmission control from any single protocol. Rather than being confined by the predefined behaviors of LTE, 5G NR, Wi-Fi, or NB-IoT, the system implements a unified control system that dynamically manages radio parameters—such as modulation, coding, and power—based on real-time link quality and network context. This cross-standard, multimode capability effectively supersedes traditional standard-driven implementations, enabling adaptive, low-latency, and spectrum-efficient communication in complex heterogeneous environments. The system dynamically controls radio access network (RAN) and physical layer parameters, including carrier aggregation, dynamic spectrum allocation, modulation and coding scheme (MCS) adaptation, beamforming configuration, channel coding, transmit power control, and frequency selection.
