Fabrication and microstructure of SiO2−GeO2 sol-gel glass coatings

SiO₂−GeO₂ sols and gel glass coatings with different contents of germanium dioxide were fabricated. Stable and transparent sols could only be obtained when the content of GeO₂ was under 35%. It is shown by SEM that only one continuous phase is observed in the coating of 65SiO₂·35GeO₂ and plenty of Ge, O and Si were all found in it. However, the separated phase is found in the coating of 60SiO₂·40GeO₂ and a large number of Ge and O. It is proved by the Raman scattering investigation that the separated phase in the coating of 60SiO₂ ·40GeO₂ is germanium dioxide. The congeries of hydrolystates of Cl₃ GeCH₂ CH₂ COOH play the main role in the formation of the separated phase when the proportion of GeO₂ is much higher. Si−O−Ge, Si−O−Si, and Ge−O−Ge bonds form in the coating of 65SiO₂·35GeO₂ and this coating is homogenous.

镉质量浓度和鱼尺寸对罗非鱼积累和转移镉的影响

为研究尺寸和镉(Cd~(2+))质量浓度对罗非鱼积累和转移水环境中Cd~(2+)的影响,用室内培养的方法,选取4种尺寸的罗非鱼,设置不同质量浓度Cd~(2+)的暴露试验,分别测定其半致死率、Cd~(2+)积累量和对Cd~(2+)的转移系数以及罗非鱼的相对增长率.结果表明:不同尺寸的罗非鱼对Cd~(2+)的响应不同,其中,幼龄鱼的LC50浓度最低,体长为31.5±3.4 cm的罗非鱼LC50最高;低质量浓度Cd~(2+)(0.5 mg/kg)处理下,罗非鱼尺寸不同,相同鱼组织对Cd~(2+)的吸收积累量差异显著(P0.05),而高质量浓度Cd~(2+)处理时,不同尺寸罗非鱼的同一组织对Cd~(2+)的积累量无显著性差异;除体长27.4±2.9 cm罗非鱼外,相同尺寸的罗非鱼Cd~(2+)转移系数都是低质量浓度显著大于高质量浓度(P0.05);高质量浓度Cd~(2+)处理对各种尺寸罗非鱼质量增加的抑制率显著高于低质量浓度Cd~(2+)处理的抑制率.此外,不同Cd~(2+)质量浓度对相同尺寸的罗非鱼也产生不同的影响.因此,罗非鱼的尺寸和Cd~(2+)质量浓度都对罗非鱼积累和转移Cd~(2+)产生影响.     

The electronic structure and grain boundary segregation by boron addition

The electronic structure and grain boundary segregation caused by boron addition to Ni₃Al have been studied by X-ray photoelectron spectroscopy and Auger electron spectroscopy, respectively. The obtained results show that the Ni2p_3/2 electron binding energy rises gradually in the sequence of pure Ni<Ni₇₆Al₂₄<Ni₇₄Al₂₆<Ni₇₅Al₂₅, while it reduces monotonously with an increase in boron addition to Ni₃Al. Besides, it is found that the grain boundary segregation of boron occurring in Ni₃Al is a combined equilibrium and non-equilibrium type in nature. Based on the concept of the bonding environmental inhomogeneity, measured by the shift in Ni2p_3/2 electron binding energy from the nickel atoms in the simple substance nickel to those in the intermetallic compound Ni₃Al (ΔE _B), being responsible for the brittle behavior of the alloy, a binding energy shifting criterion for the brittle-ductile fracture transition in Ni₃Al is presented; when ΔE _B>0, the brittle failure occurs in Ni₃Al; when δE _B<0, the ductile one appears. Combined with the above experimental rules, the criterion predicts that pure Ni₃Al is brittle, and there exist the stoichiometric effect and concentration effect in the ductilization process for Ni₃Al by boron addition. Hence the criterion can be taken as a theoretical guide to alloy design in developing ductile intermetallics. Project supported by the National Natural Science Foundation of China.

不同类型稻田亚硝酸型CH4厌氧氧化潜力的比较研究

甲烷(CH₄)厌氧氧化是稻田土壤中消减温室气体排放的重要过程.本试验选择内陆性南京稻田和滨海性上海崇明岛围垦稻田,比较研究稻田耕层(0~10 cm)和深层(50~60 cm)土壤中亚硝酸盐型CH₄厌氧氧化(n-DAMO)潜力的差异及其微生物驱动机制.结果表明,南京稻田耕层土壤的n-DAMO速率为3.51 nmol·g^-1·d^-1(以¹³CO₂计),显著高于围垦稻田耕层土壤(1.43 nmol·g^-1·d^-1).两种类型稻田耕层土壤的n-DAMO速率均显著高于深层土壤.南京稻田和围垦稻田M.oxyfera-like细菌的16S rRNA基因拷贝数分别为(2.31~4.82)×10⁷和(0.89~2.12)×10⁷ copies·g^-1,与亚硝酸盐型CH₄厌氧氧化速率显著正相关.相关性分析发现,土壤有机碳、总氮、无机态氮是稻田n-DAMO速率分异的重要原因.综上所述,内陆性稻田土壤n-DAMO氧化潜力较高,其主要由较高的土壤本底碳、氮水平和功能微生物丰度所致.

Effect of electrolysis superheat degree on anticorrosion performance of 5 Cu/（10NiO-NiFe2O4） cermet inert anode

5Cu/(10NiO-NiFe2O4) cermet inert anodes were prepared by cold-pressing and sintering process, and the effect of superheat degree of melting K3AlF6-Na3AlF6-AlF3 on their anticorrosion performance was studied under electrolysis conditions. The results show that, the fluctuation of cell becomes small with increasing of superheat degree, which is helpful to inhibit the formation of cathodic encrustation; the concentration of impurities from inert anode in bath goes up to certain degree, but it is far smaller than those in traditional high-temperature bath. Increasing the superheat degree of melting K3AlF6-Na3AlF6-AlF3 has unconspicuous effect on the contents of impurities in cathodic aluminum. The total mass fractions of Fe, Ni and Cu in aluminum are 15.38% and 15.09% respectively under superheat degree of 95 and 195 ℃. From micro-topography of anode used view, increasing the superheat degree can aggravate corrosion of metal Cu in inert anode, and has negative influence on electrical conductivity of electrode to some extent.     

Hydrothermal preparation and crystal habit of X-zeolite powder

The preparation of X-zeolite powder was investigatedin hydrothermal system, the crystal growth process of X-zeolite in hydrothermal condition was characterized by means of X-ray diffraction, scanning electron microscope and infrared ray. The results show that X-zeolite powder with uniform granularity and intact crystal shape can be obtained in hydrothermal system of acid-treated stellerite-NaOH-NaAl(OH)4-H2O; the crystallite size is in the range of 2 - 3μm. The best reaction time of hydrothermal preparation is 6 h. The formation phases of X-zeolite crystal are as follows: dissolution of feedstocks → formation of [SiO4]4- and [AlO4]5- tetrahedron, many-membered ring,β cage → formation of crystal nucleus and nano-particle → aggregation growth of nano-particle → coalescence growth of crystallite. The crystal habits of X-zeolite are intimately related with crystallization orientation ofβ cage in crystal and with its coupling stability on every crystal face family.
