Quantum conductivity exponent of a fractal non-branching Koch curve

Solid State Communications

Quantum coherence effect on the conductance scaling law G similar to L(-theta) of a fractal nonbranching Koch curve is addressed. The quantum conductivity exponent theta of the fractal is exactly solved by combining the Landauer formula with a renormalization decimatio...

Surface Nanocrystallization (SNC) of Metallic Materials-Presentation of the Concept behind a New Approach

Ke LU , Jian LU

材料科学技术（英文）

In this paper, a concept of surface nanocrystallization (SNC) of metallic materials is introduced. Three types of SNC processes are classified. Different SNC mechanisms and possible techniques for SNC are discussed with emphasis on mechanically induced surface self-nanocrystallization. Further devel...

Nanomechanics of fiber-like nanomaterials

Z.L.Wang

材料科学技术（英文）

Property characterization of nanomaterials is challenged by the small size of the structure because of the difficulties in manipulation. Here we demonstrate a novel approach that allows a direct measurement of the mechanical properties of individual nanotube-like structures by in-situ transmission e...

ANALYSIS OF THE INTERGRANULAR FRACTURE SURFACE BY THE FOURIER SPECTRUM METHOD

Materials Science and Engineering a-Structural Materials Properties Microstructure and Processing

A quantitative analysis of the fracture surface of a 1045 steel was undertaken in order to relate important microstructural features to brittle intergranular fractures in the steel. It was found that the character of the profile was not random but periodic. There is a direct ...
