In underground mining and tunneling projects, directional fracture-controlled blasting is critical for precise tunnel formation and reducing over- and under-excavation. However, the presence of well-developed joints in r...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

This study investigates the effect of discharge voltage on fracture distribution and fragmentation extent in multi-hole pulsed discharge rock fragmentation. Comparative experiments were conducted on red sandstone specime...

Refined delay blasting using digital electronic detonators has been widely used in rock breaking engineering, where notched borehole could control the direction of explosion-induced crack propagation. This study investig...

To investigate the influence of cracks and gaps on the reaction evolution characteristics of aluminum-containing DNAN-based explosives after the formation of mechanical induced hotspots, explosive charge samples with dif...

Efficient and highly accurate road crack detection algorithms are particularly important in road inspection systems. However, some of their limitations have gradually come to the fore as the target detection aspect has b...

Ethylene is an important raw material, and ethylene cracking furnaces (ECFs) are the core equipment sources of ethylene plants. The quality of the operation of the ECF directly affects the overall economic benefits of th...

Abstract NiFe2O4/H-ZSM-5 and NiFe2O4/SiO2 catalysts were prepared via co-precipitation method followed by physical mixing with a 1:1 loading ratio. Their catalytic performance for direct methane decomposition was evaluat...

This study investigates the failure and energy dissipation patterns of tuff under impact loads with varying occurrence conditions in Dahongshan Copper Mine through Split Hopkinson pressure bar (SHPB) tests, digital image...

SiC reinforced aluminum matrix composites (AMCs) are widely employed in various fields, and great importance has been attached to SiC/Al interface. Here, SiC/2009Al AMCs are fabricated for further research into SiC/Al in...

Abstract To ensure the prefabrication quality of concrete segmental beams for assembled railway bridges, this study investigates the main factors affecting the casting and curing of such beams. Using the Zheng-Xu regiona...

This study investigates how four nano-additives, namely graphene, amine-functionalized graphene, hexagonal boron nitride (hBN), and multi-walled carbon nanotubes, affect the properties of polylactic acid (PLA) used in ma...

Deep beams are an important element in infrastructure and offshore structures. This paper investigates the shear capacity of glass fiber reinforced polymer GFRP reinforced high-strength fibrous concrete deep beam. (12) s...

ABSTRACT Silicon anodes require binders that not only buffer volume changes but also preserve interfacial integrity. However, excessive encapsulation limits ion transport and long–term stability. Here, we develop a lip...

Abstract This study aims to develop a performance grade (PG) zoning map for asphalt pavements along the Kabul–Salang Highway in Afghanistan, considering local climatic conditions and traffic factors, to support optimiz...

BackgroundHMPV is a leading cause of pediatric lower respiratory tract infections, second only to respiratory syncytial virus in causing severe pneumonia in children. Its clinical presentation closely mimics other common...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

With the expanding use of woven composites in critical load-bearing applications under harsh environmental conditions, it is essential to evaluate how hygrothermal exposure affects their performance. This study aims to s...

BackgroundIn practical engineering, the waterproof coal pillar usually suffers from different degrees of dynamic load from the overlying strata, and its internal water distribution is non-uniform. Although the traditiona...

This study examines the mechanical and fracture behavior of glass fiber-reinforced epoxy laminates enhanced with graphene nanoplatelets (GNPs) to explore the effect of GNP through-thickness distributions on tensile, pin-...

Abstract A fiber laser was used to perform multiple laser cladding passes on AISI 1045 steel to fabricate SiC particle-reinforced Ni60A alloy coatings. The microstructure and phase composition of the cladding layers were...

Abstract Friction Stir Welding (FSW) is a reliable solid-state joining technique for aluminium alloys, where conventional fusion welding often causes porosity, solidification cracking, and excessive heat-affected softeni...
