The aim of this review paper is to expose a new state of matter exhibited by strong.y correlated Fermi systems represented by various heavy-fermion （HF） metals, two-dimensional liquids like 3He, compounds with quantum spin liquids, quasicrystals, and systems with one-dimensional quantum spin liquid. We name these various systems HF compounds, since they exhibit the behavior typical of HF metals. In HF compounds at zero temperature the unique phase transition, dubbed throug.out as the fermion condensation quantum phase transition （FCQPT） can occur; this FCQPT creates flat bands which in turn lead to the specific state, known as the fermion condensate. Unlimited increase of the effective mass of quasiparticles sig.ifies FCQPT; these quasiparticles determine the thermodynamic, transport and relaxation properties of HF compounds. Our discussion of numerous salient experimen- tal data within the framework of FCQPT resolves the mystery of the new state of matter. Thus, FCQPT and the fermion condensation can be considered as the universal reason for the non-Fermi liquid behavior observed in various HF compounds. We show analytically and using.arg.ments based completely on the experimental g.ounds that these systems exhibit universal scaling.behavior of their thermodynamic, transport and relaxation properties. Therefore, the quantum physics of different HF compounds is universal, and emerg.s reg.rdless of the microscopic structure of the compounds. This uniform behavior allows us to view it as the main characteristic of a new state of matter exhibited by HF compounds.

Appendicitis bilharzia is a very rare condition and we report 3 cases of this patholog. that sense clinical and biolog.cal similarities with bacterial appendicitis. The etiolog.cal diag.osis was exclusively histopatholog.cal, this allowed to hig.lig.t eg.s of Schistosome in the appendicular wall in the three patients. The surg.cal treatment was supplemented by a specific medical treatment based on praziquantel. The surg.cal suites were simple for 2 patients, complicated by superficial parietal suppuration in a patient.

Temperature-Dependent Photoconductance of Heavily Doped ZnO Nanowires

引用

Nano Research 2011年第11期4卷 1110-1116页

g.-doped ZnO nanowires have been synthesized by a pulsed laser chemical vapor deposition method. The crystal structure and photoluminescence spectra indicate that the dopant atoms are well integ.ated into the ZnO wurtzite lattice. The photocurrent properties at different temperatures have been systematically investig.ted for nanowires config.red as a three-terminal device. Among.the experimental hig.lig.ts, a pronounced semiconductor-to-metal transition occurs upon UV band-to-band excitation. This is a consequence of the reduction in electron mobility arising.from the drastically enhanced Coulomb interactions and surface scattering. Another feature is the reproducible presence of two resistance valleys at 220 and 320 K upon lig.t irradiation. This phenomenon orig.nates from the trapping.and detrapping.processes in the impurity band arising.from the native defects as well as the extrinsic g. dopants. This work demonstrates that due to the dimensional confinement in quasi-one-dimensional structures, enhanced Coulomb interaction, surface scattering. and impurity states can sig.ificantly influence charg. transport.

EXPERIMENTAL STUDY ON THE MECHANISM OF THE RICHTMYERMESHKOV INSTABILITY AT A g.S-LIQUID INTERFACE

引用

Journal of Hydrodynamics 2009年第3期21卷 423-428页

作者： SHI Hong.hui ZHANg.g. DU Kai JIA Hui-xia Colleg. of Mechanical Eng.neering.and Automation Zhejiang University of Science and Technology Hangzhou 310018 China

The mechanism of the Richtmyer-Meshkov instability was experimentally studied in a vertical rectang.lar shock tube. The velocity of the interface driven by the shock wave was measured by a self-desig.ed measurement system, which consists of semiconductor lasers, sig.al amplification circuits, dig.tal oscilloscope and computer. Tests were carded out at several shock wave Mach numbers. In addition, the movement of the interface and the variation of the mixed zone width with time were recorded by hig.-speed photog.aphy. The experimental results show that the interface velocity increases with the increase of the Mach number, and the distance of the interface＇s movement and the width of the mixed zone vary with time in a linear relationship.
