고각 환형 암시야 주사투과전자현미경기법과 투과전자현미경기법을 이용한 상용 청색 발광다이오드의 종합적인 구조분석
This study suggested comprehensive structural characterization methods for the commercial blue light emitting diodes(LEDs). By using the Z-contrast intensity profile of Cs-corrected high-angle annular dark field scanning transmission electron microscope(HAADF-STEM) images from a commercial lateral GaN-based blue light…
Quantum Electronic Matter in Two Dimensions
Most often, the electrical properties of a material are described as either "conducting" or "insulating". Copper, everyone knows, is a good conductor. It is the foundation of the electrical infrastructure of the nation. Glass, on the other hand, is an excellent insulator. But do these two words describe all the possib…
The Cementitious Barriers Partnership Experimental Programs and Software Advancing DOE’s Waste Disposal/Tank Closure Efforts – 15436
The U.S. Department of Energy Environmental Management (DOE-EM) Office of Tank Waste Management-sponsored Cementitious Barriers Partnership (CBP) is chartered with providing the technical basis for implementing cement-based waste forms and radioactive waste containment structures for long-term disposal. DOE needs in t…
On the modification of non-regular linear functionals via addition of the Dirac delta function

Molecular and nanodimensional metal based systems for the therapy against neurodegenerative diseases
Reactive oxygen species (ROS) are harmful species produced during metabolic processes, such as photosynthesis and respiration, of living organism. In both case, the substrate (oxygen/water) undergoes several multi electronic reaction, during which some electrons can “escape” from the catalytic cycle and produce ROS, s…
NEW SUBCLASSES OF ANALYTIC AND BI-UNIVALENT FUNCTIONS INVOLVING BECKER
In the present paper, we introduce two new subclasses of the function class $\Sigma$ of bi-univalent functions involving Becker defined in the open unit disc $\U:=\{z:z\in \mathbb{C},\;|z|<1\}$. The estimates on the coefficients $|a_2|$ and $|a_3|$ for functions in these new subclasses of the function class $\Sigma$ a…

含水量对TiO 2 纳米管形貌控制参数的影响
以不同含水量的乙二醇溶液为电解液，采用阳极氧化法制备TiO2纳米管阵列。通过记录反应过程中电导率、粘度及回路电流随时间的变化曲线，研究含水量对电解液粘度、电导率及电流等过程参数的影响，分析了纳米管形貌尺寸与TiO2溶蚀所耗电荷量的关系。粘度初始值和初始电导率均与含水量呈三次关系，相关系数分别为0.992 5和0.977 8。在反应过程中，溶液粘度值有缓慢增加的趋势。由于不同含水量的电解液粘度的不同，H+和OH-数量不同，F-迁移速率不同，电导率-时间曲线及电流-时间曲线具有不同的变化趋势，并对其进行了理论分析。当水体积分数为4%，5%，6%和10%时，纳米管的形貌较为有序并且TiO2纳米管阵列表面的碎片较少，纳米管直径变化范围为5…
HOMOPROTOKATEKOLAT DİOKSİJENAZ (HPKD) ENZİM AKTİF MERKEZİNİN İKİNCİL KOORDİNASYON ETKİLERiNİN KURAMSAL ANALİZİ
Fe-HPCD is a non-heme extradiol enzyme that operates in the oxidative ring opening pathways of aromatic compounds.[1,2] Recent studies showed that the proton transfer to afford 3 or 4 from 0 (Figure 1) is assisted by an His200 residue that is lying in the secondary sphere of HPCD active site.[3,4] Thus, the main role…

具有异质结的富勒烯C 60 /酞菁纳米复合材料的可见光响应光催化应用
Organic semiconductor nanoparticles composed of fullerene C60 and/or metal-free phthalocyanine (denoted as Pc) were synthesized by a reprecipitation method, in which N-methyl-2-pyrrolidone (NMP) solutions dissolving C60 and/or Pc were injected into another solvent (e.g., water or ethanol, denoted as poor solvent). The…
Double-Diffusive Convection During Growth of Halides and Selenides
Heavy metal halides and selenides have unique properties which make them excellent materials for chemical, biological and radiological sensors. Recently it has been shown that selenohalides are even better materials than halides or selenides for gamma-ray detection. These materials also meet the strong needs of a wide…
On the Failure Locus of Isotropic Materials in the Stress Triaxiality Space
The aim of this paper is to contribute to the prediction of the failure of materials (ductile and brittle) with a single criterion (rule) not violating the assumptions of continuum mechanics. In this work, the failure behavior of isotropic materials is connected with the ability of a material to store elastic strain e…
Helical Carbon Nanotubes Alter F-Actin and ARP2 Distribution in Macrophages and Inhibit Pseudomonas aeruginosa Phagocytosis in an Intracellular Accumulation-Dependent Manner
The similarity of carbon nanotubes (CNTs) to the shape and size of asbestos fibers has raised concern over their potential pulmonary toxicity in occupational and environmental settings. Studies have demonstrated pulmonary toxicity associated with exposure to CNTs, including modulation of the pulmonary immune system an…
Synthesis of Alumina Nanowires in a Cordierite Pore Structure by a CVD Process Using a Powder Source
We fabricated a composite cordierite pore structure with alumina (Al 2 O 3 ) nanowires by a chemical vapor deposition ( CVD ) process. The Al 2 O 3 nanowires were grown in a horizontal Al 2 O 3 tube furnace by CVD using an aluminum (Al) powder source without the use of any catalysts at a temperature of 1200°C and a pr…

Effects of prestrain applied to poly(ethylene terephthalate) substrate on microstructures and morphologies of porous TiO_2 film and optical scattering behaviors of light
A mold was designed to simulate a thin ceramic film coating on a soft, flexible substrate using a rotating deposition system. With this mold, three prestrains (2%, 4%, and 6%) were applied to a polyethylene terephthalate (PET) substrate before the deposition of a thin TiO(2) film. The contact angle of the substrate an…
