Preparation and Dielectric Properties of Polyethylene Composites Modified by Nano‐ TiO 2 Coated Zeolites With Different Pore Sizes

ABSTRACT Low‐density polyethylene (LDPE) insulation in high‐voltage direct current (HVDC) cables is prone to space charge accumulation and electric field distortion. To address this, we propose a core–shell modification strategy using nano‐TiO 2 ‐coated porous zeolites (4A and Na...

Phase Transition Mediated Solvation Structure Regulation in Quasi‐Solid‐State Composite Electrolyte for High‐Voltage Sodium Batteries

ABSTRACT Quasi‐solid‐state composite electrolytes (QSSEs) represent a promising approach to fabricating high‐energy rechargeable batteries, but their practical implementation is hindered by structural instability and interfacial incompatibility. In this study, a QSSE was prepared...

Cloud-aided multi-party private set intersection using Chinese national cryptographic algorithms

Abstract Multi-party private set intersection (MPSI) is a fundamental primitive for privacy-preserving data collaboration, enabling multiple parties to compute the common elements of their private sets without revealing non-intersection elements. Existing MPSI protocols are mainl...

PerspectiveReview on Ammonia and Methanol: The Next-GenerationMarine Fuel for the Shipping Industry

Abstract The shipping industry is one of the leading contributors to greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has set ambitious targets under its 2023 GHG strategy, including reducing the carbon intensity by 40% by 2030 and achieving net-zero...

Reliability analysis of large area sintered Cu interconnects based on simulation and thermal shock test

Purpose The purpose of this study is to assess the thermomechanical reliability of large-area sintered Cu interconnects for automotive power modules under actual operating conditions and to determine the optimal sintering layer thickness using finite element simulation and experi...

Endowing CentrosymmetricOxides with Effective Piezoelectricityvia Oxygen Vacancy Engineering and Single-Atom Anchoring for MulticatalyticSono-Immunotherapy

Abstract Due to piezopotential-driven energy band tilting and the promotion of charge carrier separation, sonopiezoelectric therapy (SPT) holds promise in overcoming the limitations of band structure. However, the dependence of the piezoelectric effect on noncentrosymmetric cryst...

A causal evidential reasoning rule-based method for concrete compressive strength prediction

Concrete compressive strength is a key indicator for measuring structural performance and durability. Its accurate prediction is essential for engineering safety and construction quality. However, concrete strength is influenced by many material and environmental factors, making...
