Texto completoTrivedi, Darshan Parimal. "The effects of streaming potential modeled electric fields on bovine aortic endothelial cells". Thesis, Boston University, 2013. https://hdl.handle.net/2144/12862.
Texto completoBovine aortic endothelial cells (BAECs) respond to blood flow by modulation of membrane potential and nitric oxide production ([NO]). Shearing forces, mechanically generated by blood flow, have a well-described influence on BAEC biology. However, blood flow simultaneously generates an electrical streaming potential by inducing charge separation along the vascular wall. This study investigated the role of the streaming potential as a factor in BAEC biology. Within a laminar flow chamber, both shearing force and an electrical signal were recorded [0, 0.35, 1.2, 2.0 N-m^-2 ; 0-2 V-m^-1 DC/300 mV-m^-1 AC]. At constant flow onset, a membrane potential sensitive fluorescent probe, DiBAC4(3), demonstrated BAEC hyperpolarization (-8 mV, maximal at <100 secs) with depolarization back to baseline in 200 seconds. When the streaming potential was neutralized, flow onset induced a prolonged hyperpolarization (~4-6 mV, maximal at <100 seconds) without subsequent depolarization. Application of an isolated streaming potential modeled field caused a ~2 mV depolarization. Using channel blocking agents, the streaming potential effect was attributed to a flow-sensitive calcium-activated chloride channel. A nitric oxide specific fluorescent probe, DAF-2, showed [NO] to be proportional to the shearing force. When the streaming potential was neutralized, [NO] was potentiated. The pulsatile electrokinetic vascular streaming potential (EVSP), found in vivo, can be modeled mathematically by oscillating electric fields. EVSP applied to BAECs caused membrane depolarization (up to 7 mV, p < 0.05) proportional to field frequency, but not field strength. Without fluid flow, ATP stimulation of BAECs was needed to elevate [NO] into an observable range. ATP stimulated [NO] demonstrated early logarithmic (first 30 min) and subsequent (30 min to 2 hrs) exponential relationships. Simultaneous EVSP and ATP stimulation showed increased [NO] greater than ATP stimulation alone. Studies performed in ±Ca2+ media and with calcium channel blockade demonstrated effects proportional to EVSP field strength and frequency on these processes. In summary, our results provide evidence for a role of the streaming potential in the flow response of BAECs, previously attributed only to mechanical shearing forces. Streaming potential-modeled fields induced frequencydependent depolarization in BAECs. These fields decreased flow-induced [NO], and potentiated ATP-induced [NO].

Texto completoThe world has been experiencing energy-related problems following pressuring energy demands which go along with the global economy growth. These problems can be phrased in three paradoxical statements: Firstly, in spite of a massive and costless solar energy, global unprecedented energy crisis has prevailed, resulting in skyrocketing costs. Secondly, though the sun releases a clean energy, yet conventional plants are mainly being run on unclean energy sources despite their part in the climate changes and global warming. Thirdly, while a negligible percentage of the solar energy is used for power generation purposes, it is not optimally exploited since more than its half is wasted in the form of heat which contributes to lowering efficiency of solar cells and causes their premature degradation and anticipated ageing. The research is geared at addressing the issue related to unsatisfactory efficiencies and anticipated ageing of solar modules. The methodology adopted to achieve the research aim consisted of a literature survey which in turn inspired the devising of a high-efficiency novel thermal electric solar power panel. Through an in-depth overview, the literature survey outlined the rationale of the research interest, factors affecting the performance of PVs as well as existing strategies towards addressing spotted shortcomings. While photovoltaic (PV) panels could be identified as the most reliable platform for sunlight-to-electricity conversion, they exhibit a shortcoming in terms of following the sun so as to maximize exposure to sunlight which negatively affects PVs’ efficiencies in one hand. On the other hand, the inability of solar cells to reflect the unusable heat energy present in the sunlight poses as a lifespan threat. Strategies and techniques in place to track the sun and keep PVs in nominal operational temperatures were therefore reviewed.

Fuel cells are a promising new technology with the potential to benefit society through high energy conversion efficiencies, low environmental impact, and ability to deliver high quality electricity. After decades of development, the technology is on the verge of commercialization. However, fuel cell penetration of the electric power sector will be inhibited by a number of important market barriers, including high initial costs, lack of awareness, and undemonstrated operating performance. This thesis discusses the importance of developing a sound business strategy to ensure the market success of fuel cell technology. Two elements of marketing strategy are described as critical for commercialization initiatives: selecting the optimum target market for fuel cell products and designing an effective distribution strategy. A framework and criteria are proposed for choosing among alternative marketing strategies. Ongoing fuel cell commercializati0n efforts are examined in the context of this framework to derive lessons for the emerging fuel cell industry.

Texto completoLitiumjonbatterier anpassade för användning i tunga hybridfordon förbättras kontinuerligt med avseende på prestanda och livslängd men har fortfarande begränsningar som måste beaktas vid utveckling av nya hybridfordon. Syftet med denna avhandling har varit att studera och utvärdera potentiella prov- och analysmetoder lämpliga för användning i arbetet med att maximera livslängd och utnyttjandegrad av batterier i tunga hybridfordon. Ett koncept för battericykling på fordon har utvärderats. Arbetet innefattade utveckling av testutrustning, verifiering av hårdvara och mjukvara samt en längre periods validering på lastbilar. Arbetet har visat att konceptet har stor potential för utvärdering av strategier för användandet av batterier i hybridfordon, men är mindre användbar för åldring av batterier. Batterier kapslade i flexibelt förpackningsmaterial har undersökts med avseende på kapslingens hållbarhet i en krävande hybridlastbilsmiljö. Ingen påverkan på fuktinträngning kunde påvisas efter vibration och temperaturcykling av de testade battericellerna. Åldring av kommersiella battericeller av typen litiummanganoxid - litiumkoboltoxid/litiumtitanoxid (LMO-LCO/LTO) undersöktes med olika elektrokemiska metoder för att få en djupare förståelse för prestandaförändringens ursprung och för att förstå konsekvenserna av åldrandet ur en fordonstillverkares användarperspektiv. Undersökningen visade att både kapacitetsförlust och impedanshöjning till största delen var kopplat till den positiva elektroden för denna batterityp. Post-mortem analys av material från cyklade och kalenderåldrade kommersiella battericeller av typen LMO-LCO/LTO och LiFePO4/grafit utfördes för att avslöja detaljer kring åldringsmekanismerna för dessa cellkemier. Vid analys av cyklade LMO-LCO/LTO celler påvisades mangan i den negativa elektroden samt uppvisade den positiva elektroden kraftigast åldring. Vid analys av cyklade LFP/grafit celler påvisades järn i den negativa elektroden samt uppvisade den negativa elektroden kraftigast åldring.

Texto completoPulsed electric fields are widely used in research, medicine, food industry and other biotechnological processes. The interaction of one 100 µs pulse with the plasma membrane and the endoplasmic reticulum membrane was evaluated in two different cell types. Pulse amplitude ranged between 100 and 3 000 V/cm. Organelles membrane permeabilization using this kind of pulses was experimentally demonstrated for the first time. The use of such a pulse to control the spontaneous calcium oscillations in human-adipose mesenchymal stem cells was also assessed. By creating electro-induced calcium spikes of different amplitudes, the pulse can either add a supplementary spike, or, on the contrary, inhibit the spontaneous oscillations for some tens of minutes. During this inhibition period, the electric pulse-mediated addition of calcium spikes of desired amplitude and frequency is still possible. The delivery of 100 µs pulses to stem cells undergoing osteodifferentiation was also performed. The electric pulse seemed to delay the differentiation. Moreover, during osteogenic differentiation, cells cultures displayed an organization in a few cell layers. The characterization of these layers gave results that may help to obtain mature osteoblast in less time than usual one. The use of the microsecond electric pulses technology to permeabilize the plasma and the internal cell membranes as well as to modulate internal calcium concentrations is therefore interesting to study the role of calcium in many physiological processes and to manipulate the cell calcium dynamics (oscillations, waves, spikes) in different cell types. Doing so, this available, simple and easy to apply technology could be used for the modulation and the control of basic cellular functions such as proliferation, differentiation and apoptosis

Texto completoFerritic stainless steels (AISI 441, AISI444, and Crofer 22 APU) were evaluated for the application as interconnects in SOFCs. The interested properties studied were growth kinetics, area specifie resistance (ASR) and adhesion of oxide scales formed on the steels ln the temperature range 700-900°C. The AISI 441 was selected as the competitive grade for this application, but it seemed necessary to improve its ASR. The further work was then to evaluate the influence of coatings on this property, with Ti, TiO2 and TiN deposition on AISI 441 by the magnetron sputtering technique. As supposed, doping of the chromia scale by titanium increased ASR without degrading the other properties to a negative extent. Basing on investigated properties, it was concluded that TiN-coated AISI 441 exhibited the best optimised properties to be applied as SOFCs interconnect
