Tunable band gaps bilayer graphene-BN heterostructures
2010/11/19
We investigate band-gap tuning of bilayer graphene between hexagonal boron nitride sheets,
by external electric elds. Using density functional theory, we show that the gap is continuously tunable fr...

Measuring Colloidal Forces Particle Position Deviations
2010/11/17
We present a method to measure interaction forces between pairs of charged colloidal particles
suspended in a relatively low-polar medium (5 . " . 8) directly from the deviations of particle
positio...
Predictions of hadronic observables in Pb+Pb collisions at \surd sNN = 2.76 TeV from a hadronic rescattering model
Predictions of hadronic observables Pb+Pb collisions \surd sNN = 2.76 TeV hadronic rescattering model
2011/1/6
A kinematic model based on the superposition of p + p collisions, relativistic geometry and
final-state hadronic rescattering is used to predict various hadronic observables in psNN = 2.76 TeV Pb + P...
Solvation Effects in Phase Transitions in Soft Matter
Solvation Effects in Phase Transitions Soft Matter
2010/11/18
Phase transitions in polar binary mixtures can be drastically altered even by a small amount of salt. This is because the preferential solvation strongly depends on the ambient composition.
Ab initio prediction of ferrimagnetism, exchange interactions and Curie temperatures in Mn2TiZ Heusler compounds
initio prediction of ferrimagnetism Curie temperatures
2010/11/19
The Heusler compounds Mn2TiZ (Z = Al, Ga, In, Si, Ge, Sn, P, As,Sb) are of large interest due to their potential ferrimagnetic properties and high spin polarization. Here, we present calculations of t...
We present a search for β+/EC double beta decay of 120Te performed with the CUORICINO xperiment, an array of TeO2 cryogenic bolometers.
Extraordinarily Efficient Conduction in a Redox-Active Ionic Liquid
Extraordinarily Efficient Conduction Redox-Active Ionic Liquid
2010/11/19
Iodine added to iodide-based ionic liquids leads to extraordinarily efficient charge transport, vastly exceeding that expected for such viscous systems. Using terahertz time-domain spectroscopy, in co...

为提高测力传感器的测量精度和灵敏度，研制了一种以非晶态合金材料为压磁元件的测力传感器。首先，对硅钢片、坡莫合金以及铁基非晶态合金的软磁特性进行了比较，选择了国产Fe80B20辊剪薄带作为传感器铁芯冲片。其次，通过对传感器的磁路分析，推导出了它的感应输出方程。然后，根据铁磁学和现有参考资料，确定了传感器的各项技术参数。最后，对传感器的静态特性以及励磁电流强度、励磁频率的影响进行了试验研究。试验结果显...
鉴于当前实验研究结果不断地给基本粒子标准模型提出疑难，揭示轻子、夸克存在亚结构的迹象，例如EMC效应预示轻核与重核之间存在差异，p〖AKp-]碰撞单举截面分布在横能ET>200?GeV时与QCD计算发生较大偏差，发现了反轻子-夸克共振事例，先后发现了夸克的味变中性流和轻子的味变中性流，轻子的“反常量”等等．这些实验迹象都迫使我们有必要及时对基本粒子标准模型进行一番全面、系统的审视．
