China's rapid development of renewable energy sources has led to increasing short-term peak loads on the electricity grid. Coupled with the impact of extreme weather events, certain regions are experiencing tension between power supply and demand. It shows a growing inadequacy in resources to flexibly regulate and ensure the safe operation of the power grid, resulting in a significant decline in power system reliability and economic efficiency. To address these problems, Commercial Virtual Power Plant under Electricity Trading has been implemented. A Virtual Power Plant aggregates large-scale access to the grid for adjustable loads, distributed power generation, energy storage, and other regional multi-resources. Leveraging advanced information and communication technologies, the VPP integrates these diverse resources into a unified system and promote the use of these resources by users to participate in electricity market transactions. This integration enhances the grid's regulatory capacity, improves flexi

High-performance pilot-operated proportional directional valves, as critical foundational components in China's manufacturing industry, hold significant importance. However, these valves, widely utilized across various sectors in China, are predominantly monopolized by companies such as Bosch Rexroth from Germany and Atos from Italy. This monopoly situation has led to constraints on China's autonomous development in terms of technology, pricing, supply cycles, and other aspects, posing a bottleneck problem for the independent development of many major equipment in China. In addressing pilot-operated proportional directional valves, a comprehensive design of proportional valves is undertaken. Simulation and optimization analyses are conducted on proportional valves with different shapes of throttle slots to explore the impact of various slot shapes on the valves. Main valve flow validation is performed, and dynamic and static characteristics analyses are carried out on the proportional valves. Structural optimization of the valves is conducted using orthogonal experiments, and an acceleration test load spectrum is compiled based on the actual usage conditions of the proportional valve product.
Metamaterial-based sensors have been received great attention due to their high sensitivity and miniaturized size for determining the permittivity. This project presents the design and simulation of a metamaterial microwave sensor operating as a dual band sensor at 2.2GHz and 3.3GHz to determine the liquid ratio in water. The sensor was designed with split ring resonators(SRRs) and an electronic inductance circuit(ELC) resonator in the defected ground structure(DGS). The slot in the transmission line coupled with two half-ring are used for generating the resonances and the photonic band gap(PBG) structures to enhance the quality factor and improve sensitivity. The gaps in the ELC section are considered to have dual band characteristic.
The treated effluents enter the initial (receiving) tank. In the receiving tank, homogenization is carried out to a homogeneous suspension, which is fed into the KP-10 installation. A quicklime solution (Ca(OH)2). It's a cheap consumable. In KP-10, the mixture is dispersed. All molecular compounds are destroyed. Dispersion occurs due to the effects of cavitation, which occurs under the influence of magnetic bodies and fields, the structure and nature of which are a trade secret of the applicant. As a result of processing, complex compounds disintegrate, oxidize and are converted into passive forms of salts, which reduces the hazard class of the treated masses to a minimum, up to process water and harmless humus.

Grain is a major source of food, while grain security has been considered as a strategic issue in many countries. Temperature and moisture as the two key properties affect the quality of stored grain. Most existing approaches for sensing this properties are expensive, time-consuming, and are difficult to deploy. In this scheme, we utilize a commercial RFID system to affix tags onto sensing targets. The RFID reader communicates with these tags to gather tag information and acquire the target temperature and moisture. The system boasts low cost (with tags priced at only 0.3 RMB each) and facilitates easy online measurement.
The current construction waste in China is 3,000MT /y approximately, which has accounted for more than 40% of the total municipal solid waste, and is expected to reach 4,000MT in 2025, however, the recycling rate of construction waste in large and medium sized cities are not more than 10%, a great amount of waste are still treated by the mode of traditional landfill and lower class crack-sieving, which increased the conflict of "city surrounded by rubbish "and land shortage . Therefore, it is ncecessary to develop an efficient process and complete plant for construction waste pretreatment and resource recycle ,and solve the issues of prominent shortage of natural resource and environmental pollution caused by construction waste, so as to realize the waste recycle and utilization maximally, Maqiao Renewable Resource Utilization Project is just a developped successful project case of construction waste recycle industry under this backgound, which can provide a reference and demonstration to other city in environment governance and construction waste recycle field . the basic process route is as the following: Construction debris and decoration waste gathered from city and town is transported to the utilization center of construction waste and stacked separately , through preselection by labour force, then broke the bag and load material by excavator to pretreatment workshop of " two class crack, two class sieving " for construction debris or "two class crack, four class sieving" for decoration waste, then different grain sizes of recycle aggregates are produced, which of them are transported to resource utilization workshop at the down steam for producing regeneration brick ,others are sales to concrete mixing station outside as the raw material of concrete and mortar production, the plastics, wood ,metal sieved by this unit are recycled by special company , and the remained muck and light materials without values are transported to landfill yard and waste incineration plant planed by municipal authority for filling and burning , so as to realize the utilization of "reduction, harmless & recycle " to construction wastes, and promote the development of circular economy.
Climate change poses a critical global challenge, and CO2 geological sequestration is an effective strategy for reducing greenhouse gas emissions. While the successful injection of CO2 into subsurface formations is important, ensuring that it remains securely stored without leakage is crucial for the success of sequestration efforts. Immediate detection and remediation of any leakage are essential to prevent atmospheric release. Current methods, such as seismic monitoring, are often not real-time, have low accuracy, and are costly. Delayed detection means CO2 could be released for an extended period, undermining sequestration efforts. Therefore, real-time leakage detection is crucial. Experts from the Institute of Geology and Geophysics, Chinese Academy of Sciences, and Saudi Aramco have collaborated to develop a novel technology for this purpose. The major innovations include: 1. Automatic Interpretation Techniques: These techniques analyze large volumes of geological data, and stochastic discrete fracture network methods simulate various geological scenarios to enhance accuracy. 2. Deep-Learning Based Upscaling: This method generates computationally efficient geological models. 3. Bayesian Inversion Methods: Combined with deep learning algorithms, these methods identify potential leakage sites in real time. This innovative approach has been successfully adopted by Saudi Aramco and implemented in the largest carbon capture and storage (CCS) project in the MENA region.

Cross-cultural engagement in the Global South involves the sharing of ideas, norms, values, and beliefs among societies with diverse cultural backgrounds. It is crucial in a globalized world to foster mutual understanding and respect between different cultural spheres. However, issues like cultural imperialism, misinterpretation, and underdevelopment can arise. Cultural diplomacy advocates for balanced cross-cultural relations by sharing cultural heritage and resources, while intercultural competence promotes cognitive, affective, and behavioral capabilities. Local context-based development focuses on leveraging local values, norms, and belief systems to adapt development projects to local needs. Collaborative global governance ensures a multi-directional and cooperative decision-making process, reducing the influence of neo-colonial power dynamics and creating a more inclusive space for the exchange of ideas, skills, and knowledge. Addressing cross-cultural issues in the Global South requires addressing cultural imperialism, misinterpretation, and underdevelopment.
