Nitrogen fixation continues to be a problem of fundamental scientific importance.Recent progress in this research area appears to have occurred along three major lines:
FeCo/Ru/FeCo exchange coupled synthetic antiferromagnetic multilayers were prepared with two sputtering modes. One is continuous sputtering mode, and the other mode is layer‐by‐layer sputtering mode. The former mode implies that substrate faced the target and film growth process was continuous when FeCo layers were sp…
An induction heating problem can be described by a Fredholm Integral Equation of the second kind. The equation is used to compute the eddy current of density. One method for solving such an equation is the Nyström method. It is based on the approximation of the integral in an equation by the numerical integration rule…
A combination of experimental techniques is used to demonstrate that optical field concentration and Ohmic losses in planar chiral plasmonic metasurfaces depends on the handedness of circularly polarized light. Chiral dischroism in transmission is demonstrated.
We read with great interest the review article by Fan et al. [1] that discusses a range of microsurgical techniques used for vascularization and neurotization in bone tissue engineering. Not only the lack of vascularization but also the lack of neurotization within tissue engineered bone can lead to insufficient ossif…
Duality plays the main role in all mathematical theories. In wave optics based on the concept of “the zero-distance phase front,” duality takes the form of Damien’s theorem and the mirror symmetry between the conic refracting surfaces with the plane zero-distance phase front and the plane refracting surfaces with the…
We experimentally demonstrate apodized focusing fully etched sub-wavelength grating couplers for the transverse electric (TE) mode. An insertion loss of 4.2 dB, 1-dB bandwidth of 36 nm, and back reflection of -24 dB have been obtained.
In the last few decades, plasmonic nanostructures have been studied and used vividly for numerous applications ranging from medicine and diagnostics to efficiency enhancement of solar cells. In line with this, the main focus of this thesis is to investigate the applicability of plasmonic nanostructures and develop new…
Injection process is essential for many industrial applications especially in water desalination and water treatment market. The new concept of injection, line bleeding injection pump (LBIP) [8], opens a door for injection processes of simpler and effective injection facilities with relatively low cost and less mainte…
We fabricate 3D gratings and diffraction optics using direct laser writing. Diffraction patterns of gratings agree with Laue theory. We demonstrate zone plates for visible wavelengths. Direct laser writing is promising for integrated diffraction optics.
We measured the photocurrent density of quantum well (QW) and inverse quantum dot (IQD) photovoltaic devices. The photocurrent per unit area of IQD was enhanced as the carrier confinement became stronger with increasing diameter.
Extraction and SERS detection of TNT in soil.
The specific activities of natural and artificial radionuclides in 8 Water samples collected from Habiganj district in Bangladesh, have been Studied and evaluated. Experimental results were obtained by using a High Purity Germanium (HPGe) Detector and the radioactive standard sources supplied by IAEA were used to dete…
The nature of the calcium-silicate-hydrate phase in hydrated Portland cement has been the subject of considerable debate for decades. Various nanostructural models have been proposed including those constructed from colloidal-based particulate systems and those formulated on the basis of layered calcium-silicate-hydra…
The fabrication of silicon oxynitride (SiON)/ZnO nanotube (NT) arrays and their application in improving the energy conversion efficiency (η) of crystalline Si-based solar cells (SCs) are reported. The SiON/ZnO NT arrays have a graded-refractive-index that varies from 3.5 (Si) to 1.9~2.0 (Si3N4and ZnO) to 1.72~1.75 (S…
Oxidation of copper slag in air under isothermal (at 700, 760, 800, 860 and 900C) and nonisothermal (25 – 1000C) conditions is studied using simultaneous DSC-TG and DTA-TG analysis with a flow rate of the oxidizing gas of 20 ml/min. Mechanism of the oxidizing process is proposed on the basis of the thermal curves and…
以天然磷脂1,2-二-十四烷基磷脂酰胆碱(DMPC)和合成肽脂Ala制备人工细胞膜，向不同样品中分别加入10%、20%、30%的胆酸，以1,6-二苯基-1,3,5-己三烯(DPH)作为荧光试剂，利用荧光偏光法检测不同浓度胆酸对人工细胞膜的流动性的影响。结果表明，在实验设置的温度范围内，不同浓度的胆酸对DMPC囊泡的流动性影响不大。Ala囊泡在凝胶态温度下，随着胆酸浓度的增加，偏光值P值逐渐减小，流动性增大；而在液晶态温度下，不同浓度胆酸对Ala囊泡的流动性影响不大。本实验为阐明生物体内胆酸和细胞膜的相互作用机理提供了参考依据。The natural phospholipid DMPC and Ala, a kind of synt…
文章中合成了四种粒径相近，形貌不同的纳米氧化亚铜，并进行了XRD和SEM表征，知其形貌分别为球形, 立方块，六棱柱，六角形，其粒径均在20 nm左右。根据盖斯定律设计了热循环，并通过RD496-2000微热量热仪对热循环中的反应物与生成物进行溶解焓测定，经计算得到标准摩尔生成焓，其值分别为(−77.284 ± 0.191) kJ/mol, (−136.084 ± 0.194) kJ/mol, (−137.114 ± 0.203) kJ/mol, (−162.114 ± 0.220) kJ/mol。由此得到纳米氧化亚铜的标准摩尔生成焓因形貌不同而不同的结论，且形貌差别越大，标准生成焓值差别也越大。 Four kinds of nan…
Porous and specularly reflective films of inorganic silver oxide (AgO) with thickness ranging from 275-435nm have been deposited by chemical bath (CBD) in a mixed solution of silver nitrate AgNO3 and precursor of triethanolamine (TEA) maintained at a temperature of 318K. Surface morphology of the films was characteriz…
In this work, we present a calculation of the π‐bond energy in the SiH2 ═ XHn system at the QCISD(T)/6‐311++G(3df,2p) level combined with an isogyric correction, which shows that PSub‐DSSE (partly substituted divalent state stabilization energy) is a reliable methodology for analyzing the properties of doubly bonded s…
