The complete and incomplete fusion cross sections for ^(6)Li+^(209)Bi were measured using the in-beamγ-ray method around the Coulomb *** cross sections of(deuteron captured)incomplete fusion(iCF)products were re-quantified experimentally for this reaction *** results reveal that the iCF cross section is equivalent to that of complete fusion(CF)above the Coulomb barrier and dominant near or below the Coulomb barrier.A theoretical calculation based on the continuum discretized coupled channel(CDCC)method was performed for the aforementioned CF and iCF cross sections;the result is consistent with the *** universal fusion function(UFF)was also compared with the measured CF cross section for different barrier parameters,demonstrating that the CF suppression factor is significantly influenced by the ch.ice of potential,which can reflect both dynamic and static effects of break.p on the fusion process.

Using first-principles calculations and crystal structure search methods, we found that many covalently bonded molecules such as H2, N2, CO2, NH3, H2O and ch4may react with NaC l, a prototype ionic solid,and form stable compounds under pressure while retaining their molecular structure. These molecules,despite whether they are homonuclear or heteronuclear, polar or non-polar, small or large, do not show strong chemical interactions with surrounding Na and Cl ions. in contrast, the most stable molecule among all examples, N2, is found to transform into cyclo-N5-anions while reacting with NaC l under high pressures. it provides a new route to synthesize pentazolates, which are promising green energy materials with high energy density. Our work.demonstrates a unique and universal hybridization propensity of covalently bonded molecules and solid compounds under pressure. This surprising miscibility suggests possible mixing regions between the molecular and rock.layers in the interiors of large planets.

CMOS devices play a maj.r role in most of the digital design, since CMOS devices have larger density and consume less power. The integrated circuit performance mostly depends on the basic devices and its scaling methods, but in conventional CMOS devices in ultra deep submicron technology, leak.ge power becomes the maj.r portion apart of dynamic power. The demerits of the conventional CMOS is less speed and, more leak.ge, for any digital design PDP is the figure of merit which can be used to determine energy consumed per switching event, hence we designed a NOVEL NMOS and PMOS which has superior performance than conventional PMOS and NMOS, the design and performance check.d at 90 nm, 180 nm and 45 nm technology and calculate the performance values.

A NOVEL THEORY OF EFFECTiVE MEchANiCAL PROPERTiES OF CLOSED-CELL FOAM MATERiALS

引用

Acta Mechanica Solida Sinica 2013年第6期26卷 559-569页

作者： Yuli Ma Xianyue Su R.Pyrz j.ch.Rauhe The State k.y Laboratory for Turbulence and Complex Systems (LTCS) and Department of Mechanics and Aerospace Engineering College of EngineeringPeking University chinalco Research.institute of Science and Technology Department of Mechanical and Manufacturing Engineering Aalborg University

in this paper a new theory of effective mechanical properties of foam materials is proposed. A cell volume distribution coefficient is introduced to modify the original Gibson-Ashby equations of effective mechanical properties of foam materials. The constants that influence the effective modulus are replaced by the coeff^cient. Based on the modified distribution coefficient, the yield stress is also recalculated. Using X-ray microtomography, the internal structures of dif- ferent samples of polypropylene-nanoclay foam are obtained. The cell volume distributions of these samples are derived from the experiment by image analysis and the fitting curves are plot- ted. The distribution coefficient is acquired using the parameters from the theoretical model of the distribution curves. The results of the improved theory are compared with the experimental values and show good fitting quality. it was found that the precision of the improved theory is high and the cell volume distribution has an impact on the effective mechanical properties that would lead to the optimization of the synthesis procedure.

Rice fields are a maj.r source of greenhouse gases,such as nitrous oxide (N_(2)O) and methane (ch_(4)).Organic fertilizers may potentially replace inorganic fertilizers to meet the nitrogen requirement for rice growth;however,the simultaneous effects of organic fertilizers on N_(2)O and ch_(4)emissions and crop yield in paddy fields remain poorly understood and *** this study,experimental plots were established in conventional double-cropping paddy fields in the Pearl River Delta,china,including an unfertilized control and five fertilizer treatments with fresh organic fertilizer (FOF),successively composted organic fertilizer (SOF),chemically composted organic fertilizer (COF),COF supplemented with inorganic fertilizer (COiF),and chemical fertilizers (CFs)(TFOF,TSOF,TCOF,TCOiF,and TCF,respectively).Paddy field soils behaved simultaneously as an N_(2)O sink.(cumulative N_(2)O emission:-196 to-381 g N ha^(-1)) and as a ch_(4)source (cumulative ch_(4)emission:719 to 2 178 k. ha^(-1)).Compared to CFs,the effects of organic fertilizers on N_(2)O emission were not *** contrast,total annual ch_(4)emission increased by 157%,132%,125%,and 37%in TFOF,TCOF,TSOF,and TCOiF,respectively,compared to *** TCOiF,rice yield was maintained,while ch_(4)emission was not significantly increased from the paddy fields characterized by a prolonged flood *** important next step is to extend these field-based measurements to larger rice cultivation areas to quantify the regional and national-scale impacts on greenhouse gas emissions and to help determine the optimum practice for fertilizer use.

The electrochemical properties of MEH-PPV were: studied in ionic liquid([bmim](+)[PF6](-)) by cyclic voltammetry, chronoamperometry and AC impedance measurements. Both p- and n-doping of MEH-PPV were observed in the cyclic voltammograms, The chronoamperometric and AC impedance results indicate that the p-doping of MEH-PPV was controlled by the linear diffusion of counterions.
