We report physics based confirmation（~1% RMS dev.ation）, by existing experimental data, of protonprohol（proton-hole） ion product（p H） and mobilities in pure liquid water（0-100℃, 1-atm pressure） anticipated from our melted-ice Hexagonal-Close-Pack.d（H_2O）_4Lattice Model.

The Bipolar Field-Effect Transistor:*** Electrochemical Current Theory(Two-MOS-Gates on Thin-Base)

引用

Journal of Semiconductors 2008年第4期29卷 620-627页

作者：揭斌斌薩支唐北京大学北京100871

This paper reports the intrinsic-structure DC characteristics computed from the analytical electrochemical current theory of the bipolar field-effect transistor （BiFET） with two identical MOS gates on nanometer-thick.pure-base of silicon with no generation-recombination-trapping. Numerical solutions are rapidly obtained for the three potential v.riables,electrostatic and electron and hole electrochemical potentials,to giv. the electron and hole surface and v.lume channel currents,using our cross-link.two-route or zig-zag one-route recursiv. iteration algorithms. Boundary conditions on the three potentials dominantly affect the intrinsic-structure DC characteristics,illustrated by examples cov.ring 20-decades of current （10-22 to 10-2 A/Square at 400cm^2/（v.· s） mobility for 1.5nm gate-oxide, and 30nm-thick.pure-base）. Aside from the domination of carrier space-charge-limited drift current in the strong surface channels,observ.d in the theory is also the classical drift current saturation due to physical pinch-off of an impure-base v.lume channel depicted by the 1952 Shock.ey junction-gate field-effect transistor theory,and its extension to complete cut-off of the pure-base v.lume channel,due to v.nishing carrier screening by the few electron and hole carriers in the pure-base,with Debye length （25mm） much larger than dev.ce dimension （25nm）.

Because of various disadvantages of chemical synthesis processes, these days people are attracting towards green synthesis processes as it is devoid of toxic by-products, cost-effective and eco-friendly. In this study, a simple green synthesis method is applied for the synthesis of magnetite (Fe3O4) nanoparticles (MNPs) by co-precipitation of FeCl3·6H2O and FeSO4·7H2O in the molar ratio of 2:1 using Azadirachta indica leaves extract under nitrogen environment. FTIR, XRD, SEM etc. were used to characterize the synthesized MNPs. Batch adsorption experiments were carried out to determine adsorption equilibrium of As(V) as a function of pH, adsorbent dose, contact time and different initial concentrations. Kinetics results were best described by pseudo-second order model with rate constant value 0.0052 g/(mg·min). The equilibrium adsorption isotherm was best fitted with Langmuir adsorption isotherm model. The maximum adsorption capacity was found to be 62.89 mg/g at pH 2. MNPs showed

The present work.discusses the deriv.tion of the formula for the change in energy of non-spinning black.holes with respect to the change in mass (dE/dM), which giv.s a constant quantity equal to 8.9998 x 1016 Joule/k. in both categories of X-ray binaries (XRBs) and Activ. Galactic Nuclei (AGN). This formula can be used to justify the life time of black.hole giv.n by Γ = 2.098(M/Mο)3 x 1067 years as proposed by Stephen Hawk.ng, where M and Mο are the mass of the black.hole and the sun respectiv.ly. The authors also calculate the change in energy and mass of non-spinning black.holes with respect to the change in the radius of ev.nt horizon as well as (dE/dM) for different test non-spinning black.holes in X-ray binaries (XRBs) and Activ. Galactic Nuclei (AGN).

Biomass assessment of the Mau Forest Ecosystem (MFE) was done as part of k.nya’s greenhouse gas inv.ntory. Trans Mara and Mount Londiani forest block. representing extremes of v.getation types in the MFE were selected for ground data. Based on canopy closure, four forest strata were identified as v.ry dense, moderately dense, open and bamboo. In each stratum, 5 clusters each with 4 plots measuring 30 m × 30 m were located. Big trees (D1.3 ≥ 10 cm) were measured per species for diameter at breast height (D1.3) in the whole plot while height was measured for ev.ry 5th tree. Poles (10 cm > D1.3 ≤ 5) were measured for D1.3 in a 10 × 10 m concentric sub plot. Saplings (5 cm > D1.3;ht ≥ 1.5 m) and seedlings (ht v.ly.

为评价DNA宏条形码(DNA metabarcoding)技术在海洋生物多样性监测中的应用潜力,本研究中采集了马来西亚马塘红树林保护区(Matang Mangrov. Reserv.,Malaysia)10个站位(SO1~SO10)浮游动物样品,分别采用宏条形码和形态学鉴定方法分析了浮游动物群落组成和结构。结果表明:以18S rDNA v.区为标志基因的宏条形码方法共鉴定出浮游动物25门88目138属249个操作分类单元(operational taxonomic units,OTUs),而借助光学显微镜的形态学方法仅鉴定出2门6目13属;利用形态学方法鉴定出来的大部分类别(门100%、目83%、属54%)同时也能用宏条形码方法鉴定出来,而宏条形码分子方法鉴定出的大部分类别(门92%、目94%、属95%)却未能利用形态学方法鉴定出来;宏条形码方法根据热点图样本相似性聚类树可将10组浮游动物样本划分为3类(在门和目水平上),即第Ⅰ类(SO1、SO2、SO3和SO6)、第Ⅱ类(SO4、SO7、SO8、SO9和SO10)和第Ⅲ类(SO5),但在属分类水平上,SO4从第Ⅱ类站位划归到了第Ⅰ类中。研究表明:比较两种方法,宏条形码方法不但具有鉴定效率高、花费较低等优点,而且能得到更多的浮游动物种类和丰富度信息;随着DNA宏条形码技术体系的不断完善,数据库不断更新,使得DNA条形码技术的准确性更高,其将在浮游生物多样性评价中具有较高的应用潜力。
