Two-dimensional materials gets a new theory for control of properties（图）
Two-dimensional materials new theory control of properties
2017/10/26
Desirable properties including increased electrical conductivity, improved mechanical properties, or magnetism for memory storage or information processing may be possible because of a theoretical met...
A fast,non-destructive test for two-dimensional materials
A fast non-destructive test two-dimensional materials
2017/7/19
Thinning a material down to a single-atom thickness can dramatically change that material's physical properties. For example, graphene, the best-known 2D material, has unparalleled strength and electr...
Stenciling with atoms in two-dimensional materials possible
Stenciling two-dimensional materials possible
2017/7/19
The possibilities for the new field of two-dimensional, one-atomic-layer-thick materials, including but not limited to graphene, appear almost limitless. In new research, Penn State material scientist...
Controlling the properties of matter in two-dimensional crystals
Controlling the properties two-dimensional crystals
2016/11/29
By creating atomic chains in a two-dimensional crystal, researchers at Penn State believe they have found a way to control the direction of materials properties in two- and three-dimensional crystals ...
Two-dimensional finite element simulation of fracture and fatigue behaviours of alumina microstructures for hip prosthesis
alumina crack finite element fatigue fracture ceramic microstructure
2012/4/19
This paper describes a two-dimensional (2D) finite element simulation for fracture and fatigue behaviours of pure alumina microstructures such as those found at hip prostheses. Finite element models a...
On the critical nature of plastic flow: one and two dimensional models
plasticity dislocations self-organized criticality Frenkel-Kontorova model statistics of avalanches intermittency
2012/2/24
Steady state plastic flows have been compared to developed turbulence because the two phenomena share the inherent complexity of particle trajectories, the scale free spatial patterns and the power la...
Hysteretic magnetoresistance and thermal bistability in a magnetic two-dimensional hole system
Hysteretic magnetoresistanc thermal bistability a magnetic two-dimensional hole syste
2011/9/8
Colossal negative magnetoresistance and the associated field-induced insulator-to-metal transition, the most characteristic features of magnetic semiconductors, are observed in n-type rare earth oxide...
Determination of the boundary conditions in two-dimensional solidification of pure metals
Artificial Intelligence methods Solidification Inverse Stefan problems
2010/2/8
Purpose: Solidification of pure metal can be modelled by a two-phase Stefan problem, in which the distribution of temperature in solid and liquid phases is described by a heat conduction equation with...
