Scriptless cross-chain deferred asset transfer for AIoT

In AIoT service scenarios such as sensing-as-a-service and edge AI outsourcing, a service requester may need to establish a payment commitment before service execution, while final transaction should be deferred until service delivery is verified. When the requester and the provi...

Transforming waste into multifunctional biochar catalysts for pollution control: Synthesis strategies, catalytic mechanisms, and practical challenges

Abstract Converting waste feedstocks into multifunctional biochar catalysts provides a promising route for coupling solid‐waste valorization with pollution control. However, existing studies often emphasize individual removal performance, while the relationships among feedstock c...

Scribe: Private Web2-to-Web3 eligibility proofs for decentralized applications with transparent STARKs

Decentralized applications increasingly require eligibility checks based on Web2-held attributes, yet provider-side signing and centralized attestations limit deployability and can expose sensitive user data. This paper presents Scribe , a distributed eligibility verification ser...

Microstructural Evolution, HAZ Softening and Failure Behavior of Large-Diameter QT/AR 1045 Steel CDFW Joints

As piston rods for excavator boom hydraulic cylinders shift from integral forging to welded assemblies of separately manufactured rod bodies and rod heads, joint reliability becomes critical to load-bearing performance. In this study, 60 mm diameter quenched-and-tempered/as-rolle...
