The influence of TiO<sub>2</sub> nanoparticle incorporation on surface potential decay of corona-resistant polyimide nanocomposite films
No full textPI nanocomposite films containing surface modified nanoparticles by employing silane coupling agent were prepared using in-situ dispersion polymerization process. The surface potential decay measurements on films were investigated over the different negative corona-charged voltages and times in a controlled environment where temperature and relative humidity were kept at 21 ºC and 45%, respectively. There is a significant change in the surface potential decay characteristics after nano-fillers were introduced into polyimide. The surface potential decay pattern depends also on the amount of nano-fillers. The possible surface potential decay and corona resistance mechanisms responsible for the observed phenomena were discussed
Converting normal insulators into topological insulators via tuning orbital levels
No full textTuning the spin-orbit coupling strength via foreign element doping and modifying bonding strength via strain engineering are the major routes to convert normal insulators to topological insulators. We here propose an alternative strategy to realize topological phase transition by tuning the orbital level. Following this strategy, our first-principles calculations demonstrate that a topological phase transition in the cubic perovskite-type compounds CsGeBr[subscript 3] and CsSnBr[subscript 3] could be facilitated by carbon substitutional doping. Such a unique topological phase transition predominantly results from the lower orbital energy of the carbon dopant, which can pull down the conduction bands and even induce band inversion. Beyond conventional approaches, our finding of tuning the orbital level may greatly expand the range of topologically nontrivial materials.Ministry of Science and Technology of the People's Republic of China (Grant 2011CB606405)Ministry of Science and Technology of the People's Republic of China (Grant 2011CB921901)National Natural Science Foundation (China) (Grant 11334006)National Science Foundation (U.S.).

L. fem. adj. <i>lutea</i> yellow, being a yellow organism).</p> <p> An aerobic, Gram-stain-positive actinobacterium that grows well and forms an extensively branched substrate and aerial mycelia. Chains of rod-shaped spores with smooth surfaces are produced on ISP 2 medium. The strain shows good growth on ISP 2, CA and BA media, moderate growth on ISP 1, ISP 3, ISP 4, ISP 6 and ISP 7 media, and poor growth on ISP 5 and NA. No diffusible pigment is produced.

Hydrolysis of starch and aesculin, production of H 2 S and urease, milk coagulation and peptonization, nitrate reduction and liquefaction of gelatin are negative. D- Fructose, D- galactose, inositol, lactose, D- mannose, raffinose, L- rhamnose, D- ribose, D- sorbitol, sucrose and D- xylose are utilized as sole carbon sources, but L- arabinose, D- glucose, maltose and D- mannitol are not.

No full textTheranostic Applications of Gold Nanoparticles in Radiosensitization and X-Ray Fluorescence Computed Tomography Imaging
No full textIn recent years gold nanoparticles (AuNPs) have become a very intriguing tool for potential use in cancer therapy and cancer imaging. Many publications show AuNPs ability to improve radiation therapy (RT) in silico, in vitro, and in vivo by physical, chemical, and biological mechanisms. Additionally, the ability to better visualize cancerous areas and monitor AuNP biodistribution has been shown in silico, in vitro and in vivo using x-ray fluorescence computed tomography (XFCT) imaging. However, there are many disparities between physical models of AuNP-mediated radiosensitization and observed biological endpoints, such as cell survival; and pencil beam XFCT imaging is relatively slow and is limited to small animals/phantoms. This dissertation aims to further elucidate physical and chemical mechanisms of AuNP-mediated radiosensitization, decrease pencil beam XFCT imaging time, and show feasibility of large phantom XFCT imaging. TOPAS and TOPAS-nBio Monte Carlo (MC) simulation toolkits were utilized to help guide and optimize the research on these topics.The results presented here provide valuable insight into the physical and chemical mechanisms of AuNP radiosensitization. Additionally, dual-pencil beam XFCT imaging was shown to improve imaging speeds while maintaining high image quality. Finally, the feasibility of large phantom/anatomy XFCT imaging was shown. Together this research may help expedite clinical translation of a radiosensitizing AuNP and/or expand the use of XFCT imaging to monitor AuNP biodistribution in preclinical and clinical settings.</p
Leveraging Smart Lights for Passive Localization
No full textLocalization based on visible light is gaining significant attention. But most existing studies rely on a key requirement: the object of interest needs to carry an optical receiver (camera or photodiode). We remove this requirement and investigate the possibility of achieving accurate localization in a passive manner, that is, without requiring objects to carry any optical receiver. To achieve this goal, we exploit the reflective surfaces of objects and the unique propagation properties of LED luminaires. We present geometric models, a testbed implementation, and empirical evaluations to showcase the opportunities and challenges posed by this new type of localization. Overall, we show that our method can track with high accuracy (few centimeters) a subset of an object’s trajectory and it can also identify passively the object’s ID.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Embedded System
