This thesis discusses the viability of the polymer infiltration nanocomposite preparation technique for aligned carbon nanotubes (A-CNTs) as produced by two methods: pre-deposited catalyst chemical vapor deposition (CVD), and vapor-phase CVD. Both types of growth furnaces were constructed, and the resultant A-CNT "for…
Рассматриваются механизмы отклонения пучков заряженных частиц большой энергии изогнутыми кристаллами, связанные с явлением плоскостного каналирования частиц, отражением частиц от изогнутых кристаллических плоскостей атомов и многократным рассеянием частиц на изогнутых цепочках атомов кристалла (стохастический механизм…

Single-crystalline alpha-MnO2 nanowires and beta-MnO2 microcrystals have been controllably synthesized by a common hydrothermal method based on the redox reaction between MnO4 and Cr3+. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive sp…
Silicone-based compounds enable chemists to extract the desired fractions of materials from plants as well as impart cosmetic aesthetics. Here the authors discuss how to extract actives using amphiphilic silicones that have different partition coefficients, which are obtained by altering the ratio of oil-, water- and…
The electrical and luminescence properties of siliconbased tunnel transittime lightemitting diodes (LEDs) p + /n + /nSi:Er, emitting under reverse bias on the p + /n + junction in the breakdown regime, have been investigated. The roomtemperature emission power at the wavelength λ ≈ 1.5 μm (~5 μW), exter� nal quantum e…
In this Final Year Report, characterization and simulation of the major components in an optical transceiver will be the main focus. The characterization of the photodiode and the Metal Oxide Semiconductor Field Effect Transistor (MOSFET) structures will be performed using the apparatus in the Nanophotonic Laboratory.…
CS-C/SWNT complex while the strong intramolecular Coulombic interaction in CS-B results in its poor dispersibility and weakest binding energy of the CS-B/SWNT complex.

Tissue engineering is an interdisciplinary field promising new therapeutic means for replacing lost or severely damaged tissues or organs. However, the fabrication of complex engineered tissues has been hampered due to the lack of vascularization to provide sufficient blood supply after implantation. In this article,…
As there is a need to develop higher power conversion efficiency and low cost photovoltaic (PV) cells, Organic PV (OPV) has sparked the interest of many to carry out more research work in this area. \nCurrently Tin-doped indium oxide (ITO) is commonly used for one of the important components of OPV, i.e. the transpare…
A study of titanium oxynitride system for self-cleaning applications was conducted. TiO2 has been studied extensively for its photocatalytic effects. N-doped TiO2 has significantly better photocatalytic activity over TiO2 under visible light. In this project, we explored ways of developing photocatalyst using TiN as t…
Single-crystalline alpha-MnO2 three-dimensional nanostructures were synthesized via a novel redox reaction of KMnO4 and Cr(NO3)(3) under hydrothermal conditions. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), and hi…
Single walled carbon nanotubes (SWCNTs) have sparked considerable interest in biosensing applications due to their exceptional charge transport properties and size compatibility (diameter of ~1 nm) with biomolecules. Charges being confined to the nanotube surface are able to detect molecular level changes in their imm…

从原理和实验两方面分析了采用锌溶法处理Al—Zn—Fe—Si渣分离金属铝工艺的可行性。Al-Zn、Fe—zn、Si—Zn二元相图表明，当溶解温度在450℃～650℃的范围内，铝在锌中的溶解度比铁、硅大得多。溶Al—Zn—Fe～Si渣的过程中．渣中的铝被锌溶解形成Al-Zn合金液。铁、硅不溶或很少溶解形成浮渣。去渣。得到Zn—Al合金，铝从Al—Zn—Fe—Si渣中分离出来。实验表明：用此法可以将渣中的铝分离得到含铁为0．0043％、硅小于0．05％的锌铝合金，渣中的铝含量从51．68％降低到3．65％．铝的溶解率为74．42％。低温得到的合金含杂质少。
A scratch test machine is used to simulate the microforming conditions during the \n \ndie forging process. The scratch test is regarded as a miniature frictional process \n \nwhich is similar to the die punching process with respect to contact pressure, normal force, sliding speed and distance on wear and friction.
