This work focuses on computation of simulated spectra the C2nH family (n = {1, 2,...}) of carbon chain rad-ical molecules and their silicon analogues, SiC2m+1H (m = {0, n}), that are potential carriers of the Diffuse Interstellar Bands (DIBs). High-level quantum chem-ical computations for the ground- and excited-state…
Gold nanorods functionalised with transferrin were used for photothermally induced necrosis and apoptosis of cancer cells. It was observed that the laser energy required to induce cell apoptosis is significantly lower than that for cell necrosis, indicating that photothermally induced apoptosis can be used for medical…
Pregnane glycosides previously isolated from genus Caralluma (C. Penicillata, C. tuberculata and C. russelliana) were tested for their antitrypanosomal activity. Penicilloside E showed the highest antitrypanosomal activity (IC(50) 1.01 microg/ml) followed by caratuberside C (IC(50) 1.85 microg/ml), which exhibited the…
Both modeling human body response to dynamic loading events and developing biofidelic human surrogate systems require accurate material property characterization over a range of loading rates for the various tissues that constitute the human body. This work describes a technique for measuring the shear properties of s…
Stigma proteins of Manglietia patungensis were extracted with an optimized method and separated by two-dimensional electrophesis.Stained with Coomassie Brilliant Blue R-250,858 and 865 protein spots were detected on the gels of stigma before bloom and after bloom,respectively.There were four spots,including one exclus…
Parmi les six nouveaux systemes de reacteurs nucleaires envisages par le Forum International Generation IV ; le reacteur a neutrons rapides et a caloporteur gaz est etudie en France. Ses conditions de fonctionnement nominal (haute temperature et pression d'helium) ont conduit a la selection de ceramiques non-oxydes po…
Показано, що за мiнералофлюїдологiчними i петрофiзичними показниками, враховуючи насамперед флюїдонасиченiсть надр (особливо в межах субвертикальних геофлюїдодинамiчних структур), яка фiксується термобарометрiєю i геохiмiєю газiв прожилково-вкрапленої мiнералiзацiї у вiдкладах нафтогазоносних областей i металогенiчних…
The perovskites RNiO3 (R rare earth ≠ La) are classified as a phase transition metal-insulator. The transition temperature is modulated by the size of the rare earth. The use of compound R1-xR'xNiO3 can vary transition temperature on a wide thermal range depending on the concentration of the two rare earths. The Sm1-x…
The development of planar chalcogenide glass waveguides leads the way toward integrated mid-infrared optics. As2S3 waveguides fabricated by solution casting have a transmission loss of 9.47 dB/cm at 4.8µm.
[Truncated abstract] The scientific endeavours described within this thesis attempt to create novel solutions to current scientific, commercial and industrial downfalls, and contribute to the advancement of technologies in these areas. This has been achieved through the application of theoretical and experimental prin…

Despite of the identification of dinitrosyl iron complexes (DNICs) featuring the EPR signal at g = 2.03 forty-five years ago, the de novo synthesis of DNICs in biological system remains elusive. Compared to the nitrosylation of complexes [Fe(SR)4]2–/1– (R = Ph, Et, tBu) leading to the formation of DNIC [(RS)2Fe(NO)2]–…
神經生長相關蛋白(Growth-associated protein-43; GAP-43)是一種高度表現在發育時期神經細胞軸突生長錐的膜蛋白，GAP-43負責神經發育及修復時突觸的生長、分支，改變前突觸膜(presynaptic membrane)構造以利釋放神經傳導物。本實驗室先前在蛋白質體研究中利用MALDI-TOF發現GAP-43會與一受器聚集蛋白(receptor clustering protein) - gephyrin結合。Gephyrin的功能是聚集突觸後膜上的氯離子通道神經傳導物受器，包括GABAA receptor與glycine receptor，用以增加抑制型突觸傳遞效能。GABAA receptor為大…

Ce mémoire a trait à la nitruration du phosphure d’indium. Le phosphure d’indium est un semiconducteur III-V présentant un fort potentiel dans les domaines de la micro, de la nano et de l’optoélectronique. La nitruration est un traitement de surface intervenant dans la croissance d’hétérostructures du type InN/InP. La…
Les oxydes mixtes type perovskite de formule ABO3,ces oxydes ont fait l’objet de plusieurs études dans le but de leur application,Tel que les piles à combustibles SOFC \nL’étude de la nonstoechiométrie du système LaCoO3 substitué par le strontium dans le site -A de la structure perovskite nous a permis d’affirmer que…
We summarize recent results on micromachined dielectric elastomer actuators (DEA), or artificial muscles, whose compliant electrodes are made by low energy ion-implantation into an elastomer. Out-of-plane displacements in buckling mode of over 25% of the device diameter were observed, with a response time of less than…
The motivation of this research work is focused on synthesis and electro-catalytic characterization of nano-hybrid catalysts for anode materials in fuel cell application. Carbon nanotubes are used as support to study the supporting effect for electro-catalysts. Noble metal, Pt, and metal oxide semiconductor, CeO2, hav…
The full potential of sugarcane bagasse has not been fully exploited, with the main usage in South Africa being for providing energy in sugar mill operations, and portions being utilised for paper products, animal feed and furfural production. The dissolution and subsequent reactions of cellulose from sugarcane bagass…
