L'alliberament de fàrmacs és un procediment en què un compost o un dispositiu allibera una molècula de manera controlada. D’aquesta manera, el medicament podrà ser sotmès a absorció, distribució, metabolisme i excreció. Els semiconductors nanoporosos com l'alúmina o el silici s'utilitzen per a la fabricació de vehicles de fàrmacs a causa de les seves característiques distintives, com ara: fabricació de baix cost, estructura de porus/ mida controlable dels nanotubs, química superficial adaptable, gran àrea superficial, capacitat d'alta càrrega, resistivitat química i rigidesa mecànica.

Abstract:

Intro Generic: Nanotechnology research has gained much interest in the last decades. Fabrication of materials at nano-scale levels has brought to light many new unique physico–chemical characteristics of materials which are otherwise not present in their bulk counterpart. Harvesting these new properties has led to many unique applications in biotechnology, medicine and environmental sciences in recent years. Even though many exciting innovations have already been presented, a wealth of possibilities still lies ahead further uniting the fields of biology, physics, chemistry and material scien

En aquesta tesi es planteja fabricar una cel·la solar nano-estructurada de perovskita utilitzant alúmina nano-porosa anoditzada (NAA en les seves sigles en anglès) com a suport.

El fet que la cel·la estigui nano-estructurada aportarà estabilitat davant la radiació, la temperatura i la humitat, sent aquest el principal problema d'aquests dispositius.

Abstract:

A novel way of producing nanostructures in the past decade has been through the use of an anodized alumina template. This template has dense, self-ordered nanometric pores that grow in the oxide as the aluminum is being anodized. This technique is a fairly new method of processing nanostructures, and much study and research is presently being done to understand the formation mechanisms of the highly ordered pores. Ultra-pure aluminum foil and pure aluminium single crystal plates were anodized to create porous anodized alumina, and using it as a template to electro-deposit Nickel nanostructures

Conducting polymers have been applied in different applications, such as organic solar cells, organic light-emitting diodes, and field-effect transistors. Compared with studies of conducting polymers in the bulk and thin film states, less studies focus on the physical and optical characterization of conducting polymers un the nanoscales. In this work, we study the fabrication and characterization of nanomaterials of poly(9,9-di-n-octylfluorene-alt-ben

By tuning the anodize processes, that is changing the anodize voltage, time of the electrolyte process, time of reaming process, it is possible to control its geometry. Samples were obtained by two-step anodize processes. We used 0.3M oxalic acid solution as electrolyte, an anodize voltage of 20-60 V, and a temperature of 10℃. Films with antidot array have been prepared by the sputtering of Ni80Fe20 onto anodic alumina membrane templates. The pores

Abstract:

Despite advances in solar technologies, there is still a growing and urgent demand for light-harnessing materials that enable efficient utilisation of solar energy for solar-to-fuel conversion and environmental remediation applications. Existing photocatalytic technologies present inherent limitations to achieve these goals due to wide energy bandgap and poor electrochemical properties of conventional materials. A combination of fundamental and applied materials science, nanotechnology, chemistry, photonics and applied physics offers a way forward for developing new light-confining photocataly

Abstract:

碩士<br>國立交通大學<br>應用化學系碩博士班<br>105<br>In recent years, morphology control of the polymer materials has been widely studied. The tuning of polymer morphologies can be processed in many dimensions, such as the sizes of the polymer materials, the isotropic and anisotropic properties, and the processes of the morphology transformations. For the size differences, the micro- and the nano- particles may have distinct physical or chemical properties from the bulk materials. Rayleigh instability is a common phenomenon observed in our daily lives, and it is important for the post-treatment of materials. I

It can be used under high applied bias (>110 V) for improving the uniformity of current density.

<div>Self-assembled templates allow the creation of many complex arrays of nanostructures, which would be extremely difficult and expensive, if not impossible, to realize using any of the other available fabrication techniques. The complexity of these advanced nanostructures, synthesized using the various template assisted electrodeposition techniques, can be controlled to nanometer scale range by tuning the structural properties of the template, which is achieved by adjusting its various growth parameters during the self-assembly process.</div><div>Electrodeposition allows the creation of arr
