Abstract Monotypic catalytic site for bifunctional hydrogen evolution reaction (HER) and oxygen (OER) at low overpotential is a grand challenge in alkaline water splitting. Herein, new strategy of dual‐type atomic site‐support interaction reported, which ruthenium heteroatoms are situ implanted into both the N‐C nanosheet matrix (Ru 1 ‐N‐C) supported Co 2 P nanoparticle lattice ‐P‐Co) boosting It found that Ru ‐N‐C ‐P‐Co can give rise to synergistic effect HER OER catalysis. Density...
Traditional explosives have characteristics of high risk, large vibration, and poor directional fracturing. Consequently, an instantaneous expander with a single crack surface (IESCS), which is novel non-explosive rock-breaking technique, has been developed. The roof-cutting mechanism the IESCS method, driven by high-pressure gas, was theoretically analyzed. Laboratory experiments numerical simulations proved slitting effect method to be excellent. Compared shaped-charge blasting, charge...
Changes in Impermeable Surface Area (ISA) are an important factor reflecting urban expansion. In this study, the global land surface was divided into grids of 10×10km. By using dataset (2000-2020), study analysed spatiotemporal changes ISA worldwide, and used modeling method to identify hotspots on rate change different periods. Combining Global Population Data Urban Boundary (GUB) Data, we explored patterns growth or shrinkage. The Random Forest evaluate main factors variation...
The use of explosives is restricted on some important holidays, and the handling unexploded charge very dangerous. Therefore, an innovative non-explosive technology called instantaneous expansion (IE) was developed for tunneling. IE, whose components are derived from solid wastes such as coal gangue straw conduces to realizing reuse waste. Moreover, its cost lower than explosives. Blind guns IE easy treat with water. tunneling method classified into two categories, i.e. a single fracture...
Shaped charge blasting (SCB)—a directional fracture technology—has the disadvantages of low safety, harmful gas, and dust emissions. This study proposes a new type rock-breaking technology called shaped hydraulic (SCHB) that uses water as medium instead air. To verify effectiveness method, we performed theoretical analysis. Twelve groups on-site roof-cutting tests were carried out on SCB SCHB for comparison in coal mine. The results showed that, although both methods achieved goal roof...
The key block of the basic roof is main contributor to structural stability a roadway. Research on structure great significance for promotion noncoal pillar mining with automatically formed gob‐side entry (GEFANM) technology. This paper set in engineering context GEFANM experiment at Ningtiaota Coal Mine. study fully considered differences gob caving roof‐cutting‐line side, and range rotation angles maintain stable was determined. Based this angles, safe bulking coefficients gangue...
Urbanization is a dynamic process. At different stages of urbanization, polices managing car-bon emissions should be adjusted. In this paper, two types nighttime light data and statistical 68 cities in China from 2002 to 2021 are used establish an urban development evalua-tion system comprising population, economy, construction, society subsystems. Then, were categorized into expanding, contracting, stable understand the uncertainty urbanization's impact on carbon emissions. The...
When a high-pressure water source is located near tunnel under excavation, inrush commonly associated with hydraulic fracturing effect. To study the effect of (HFEWI), flow-rock failure process analysis (F-RFPA2D) was adopted to simulate process. The simulated results indicated that stress disturbance area formed in front excavation face and fracture zone karst cavity. Similarly, concentrations characterized by concentration, local crack propagation result concentration. In addition, pore...
