Graphene has become one of the most widely researched materials lately since its discovery in 2004. It has interested scientists due to the exceptional electronic properties of the relativistic Dirac fermions. In this thesis I will present the research I have done to study the charged impurity scattering mechanism in…
Insulin assembly follows different pathways under different environments. But the mechanism of insulin assembly and the pathology of insulin-related amyloidosis diseases remain unclear. This work, illustrating different pathways of insulin aggregation induced by short peptide segment, may shed light on these research…
Die Entwicklung Nanomedizin-basierter Therapeutika (Nanomedizin = medizinsche Anwendung der Nanotechnologie) hat zum Ziel, pharmakologische Substanzen zielgerichtet zu ihrem Wirkort zu transportieren und so die mangelnde Gewebsspezifität konventioneller Wirkstoffe zu überwinden. Humanes Serumalbumin bietet sich als Ba…
Empty 55-gallon drums that formerly held transuranic (TRU) waste (often over-packed in 85gallon drums) are generated at LANL and require radiological characterization for disposition. These drums are typically measured and analyzed individually using high purity germanium (HPGe) gamma detectors. This approach can be r…
For the purpose of improving the electrochemical cycle stability of the La-Mg-Ni based A2B7-type electrode alloys, both reducing Mg content and substituting La with Pr were adopted. The La0.8-xPrxMg0.2Ni3.15Co0.2Al0.1Si0.05 (x=0, 0.1, 0.2, 0.3, 0.4) electrode alloys were fabricated by casting and annealing. The invest…
Bubbly flow is widely encountered in many engineering applications, such as those in chemical and nuclear systems, bubble column reactors and oil transportation pipes. The \n \n \n \ndeformation of bubbles as well as their interactions has significant effect on the flow field. Therefore, the understanding of bubble dy…
In this article, the potential vs time curves during the coloring process of the 430 stainless steel were tested by CS350 electrochemical workstation. The color reproduction of the colored stainless steel was controlled by same coloring time, same coloring potential, same potential difference and being colored to stab…
To accomplish the research of a PM synchronous motor driven by 15 kW at a rated speed of 120 krpm. This paper represents an approach to minimize the eddy current losses that occur frequently at high speeds. Various simulation and testing techniques are applied to grasp the physical phenomena. Here, sleeve thickness is…
Plastic Electronics, Organic Electronics, Printed or Polymer Electronics, is a branch of Materials Science dealing with Electrically-Conductive Polymers and conductive small molecules. It is called 'Organic' Electronics because the polymers and small molecules are carbon-based. This contrasts with traditional electron…
Pr3+ 为大改进共同做的使用中间红外线(中间 -- 红外) 在 2.9 m 和 2.4 m 的排出物在 Ho3+/Pr3+ 被调查共同做的 LiYF4 晶体。与 Pr3+ 离子的介绍， Ho3+:5I7 水平的荧光一生是为 Ho3+/Pr3+co-doped 水晶的 2.15 ms，并且为 Ho3+ 的一生单身地做水晶是 17.70 ms，当 Ho3+:5I6 水平的一生为 Ho3+ 从 2.11 ms 稍微减少时: LiYF4 到为 Ho3+/Pr3+ 的 1.83 ms : LiYF4。Pr3+ 的介绍极大地增加使人口减少的 Ho3+:5I65I7 的中间红外线的排放，这也被表明 Ho3+:5I7 水平当它几乎没在 Ho3+…
The application of the Life Cycle Assessment (LCA) methodology to analyze the environmental impact to different swine waste treatment systems was investigated. The first part of LCA is to organize an inventory of parameters and emissions released due to the system under investigation. In the following step of the Life…
In the present work, electroless plating was used for coating thin films consisting mainly of Ni and P on carbon fiber. Structural changes appeared upon the post-annealing at various temperatures of the Ni-P film on carbon fiber was studied using various analysis methods. Scanning, a flat surface structure of Ni-P fil…
Through this work we adopted Rotating Disk Electrode (RDE) Voltammetry to study the kinetics of oxidation and the effect of hydrazide group on ferrocene in organic medium. Thus, two different electrodes (Pt and Gc) were used in ordre to determine this latter. According to the ferrocene taken as a witness the hydrazide…
Das Keratinnetzwerk in eukaryonten Zellen verleiht den Zellen Schutz vor mechanischer Beanspruchung. Um das Verhalten von Keratinfilamenten bei mechanischer Zelldehnung in lebenden Zellen zu untersuchen, wurden SCC-25-Zellen auf Silikonmembranen kultiviert und mit Hilfe eines Zelldehnungsapparates gedehnt. Zur Verände…
. Те точки, в которых (38) больше или равно единице, принадлежат пластической области, а те в которых выражение (38) меньше нуля – упругой. На основе формул (34), (35) созданы программы, которые позволяют с любой точность строить пласти-ческие и упругие области в скручиваемом стержне. Решение тестовых задач показало х…
Organic semiconductor-based soft electronics has potential advantages for next-generation electronics and displays, which request mobile convenience, flexibility, light-weight, large area, etc. Organic field-effect transistors (OFET) are core elements for soft electronic applications, such as e-paper, e-book, smart ca…
The hydration characteristics of pre-cast concrete considering the effects of effective initial steam-curing and water-curing duration were measured and analyzed with XRD, TG, X-ray CT, SEM-BSE and MIP techniques. The results show that the effective initial steam-curing duration for pre-cast concrete with lower water-…
In the paper, the evolution of the pulse laser technology and its physical mechanism is described briefly, and the new progresses in applications of laser ablation in traditional material processing fields, such as laser drilling, cut- ting and welding, are focused on. Moreover, the latest developments of laser ablati…
article The prospect of synthesizing ordered, covalently bonded structures directly on a surface has recently attracted considerable attention due to its fundamental interest and for potential applications in electronics and photonics.
