Advanced Materials Interfaces, EarlyView.This study investigates friction and wear of AISI 52100 steel under dry sliding in CO2, air, and N2 atmospheres, with and without contact electrification. CO2 forms a stable carbon‐rich tribofilm that reduces friction by ∼30% and wear by ∼85%. High‐resolution TEM, EELS, and molecular dynamics reveal pressure‐dependent lubrication mechanisms, showing ...

意识规范场论:基于几何对偶的统一模型 Consciousness Gauge Field Theory: Unified Model Based on Geometric Duality
本文提出基于纤维丛几何的意识物理模型,将宇宙定义为信息联络场与物质曲率场的对偶系统,构建SU(2)×U(1)规范不变作用量,证明引力与规范相互作用均源于联络场的局域对称性破缺与真空凝聚。意识被严格定义为纤维丛上的水平提升过程。模型数学自洽、物理严谨,公式采用线性文本形式,可在WPS与微信传输中稳定显示。This paper proposes a physical model of consciousness based on fiber bundle geometry. The universe is defined as a dual system of information connection field and matter curvature field.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

意识规范场论:基于信息-几何对偶的统一模型 Consciousness Gauge Field Theory: A Unified Model via Info-Geometric Duality
现代物理学的割裂源于将观察者(意识)置于时空背景之外。本文提出意识规范场论(CGFT),基于纤维丛几何与信息对偶性构建统一模型。将宇宙定义为信息联络场(阴,\omega)与物质曲率场(阳,\Omega)的动态耦合。通过变分原理证明:爱因斯坦场方程与杨-米尔斯方程均源于信息场的局域对称性破缺,且引力常数G是信息场凝聚强度的宏观涌现。意识被严格定义为纤维丛上的水平提升(Horizontal Lift)与视界穿越过程。本模型数学自洽,给出了可证伪的神经微管干涉与引力常数漂移预言。The fragmentation of modern physics stems from placing the observer (consciousness) outside the spacetime ...
