In this work, surface modification of 6FDA-BisAAF fluorine-contained polyimide by or plasma was carried out and material characteristics of the surfaces after plasma treatment were investigated. X-ray photoelectron spectroscopy analysis reveals that plasma will react with carbon atoms in the polyimide structure to for…

到 TiNi 合金的混合 TiO_2 和 NiO 粉末的直接电气化学的减小被经常的电压电解成功地在 900 deg C 在熔融的 CaCI_2 表明了。电解精力消费象 23.4 kWh/kg-TiNi 一样低，尽管电流效率在初步的实验是 20.5% 。在这个过程期间， NiO 首先以高速度被归结为 Ni，由 TiO_2 伴随到是的 CaTiO_(3_x ) 的 perovskitized 逐渐地正在被减少 toNi_3Ti 和 TiNi，由 preformed Ni 的去极帮助了。为 TiNi 合金的准备的房间电压为 Ti 是比那低的。调整房间电压不仅影响了减小速度，而且把方便存取提供了给 thenickel/perovskite…
Abstract We describe and summarize the optical challenges for future instrumentation for Extremely Large Telescopes (ELTs). Knowing the complex instrumental requirements is crucial for the successful design of 30–60 m aperture telescopes. After all, the success of ELTs will heavily rely on its instrumentation and this…
With increasing requirements on the crash safety of automotive components and on virtual prototyping it becomes more and more important to model damage behaviour of structural components in crash simulations. Especially high strength steels show a lower ductility in comparison with conventional steels. To predict the…
In this paper, the ITER project, the ITER test blanket module (TBM) program and its origin are introduced briefly. The definition and development strategy of DEMO reactor, relevant to the TBM program, are summarized. The design progress and RD plans of Chinese ITER test blanket module design based on the solid breeder…
SummaryThe antifungal activity of chitosan was tested in vitro against Alternaria alternata and Geotrichum candidum, two major post-harvest pathogens of tomato. Chitosan, at all concentrations, inhibited spore germination in A. alternata and G. candidum. Survival of the yeast biocontrol agent, Candida utilis, in chito…
I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii The Solid Oxide Fuel Cell (SOFC) is a promising technology for electricit…
Purpose: This work was performed in the aim of exploring non-conventional injection moulding technique and to study the effect of processing thermomechanical treatment on the morphology and properties of polymerpolymer composites. Design/methodology/approach: Multilayered highly oriented skin regions induced by high s…
The effect of furfural benzoylhydrazone and its derivatives (I-VII) as corrosion inhibitors for C-steel in 1M phosphoric acid solution has been studied by weight-loss and galvanostatic polarization techniques. A significant decrease in the corrosion rate of C-steel was observed in the presence of the investigated inhi…
This experimental study mainly focuses on the effects of overfeed ratio, twist direction and amount of twist of the binder yarn, and the effect of yarn count on the properties of bouclé yarns and their performance in single jersey and rib (1 × 1) structures. Based on the results, it is evident that the twist direction…
A new magnetostriction sensor and an on-line liquid level and density measuring equipment were developed. The operating principle of the measuring equipment with magnetostrictive sensor was described and a multi-floater relative displacement algorithm based on Wiedemann and Viuary Effect was brought forward. The effec…
Novel MCM-41 aluminosilicate/aluminophosphate materials that exhibit good mesostructural ordering have been synthesized and characterised; the synthesis of these silicoaluminophosphates involved the use of gel mixtures containing amorphous mesoporous aluminosilicate and aluminophosphate phases as precursor.
FSM-16, a mesoporous silica, was found to catalyze oxidative photo-decarboxylation of alpha-hydroxy carboxylic acid, phenyl acetic acid derivatives and N-acyl-protected alpha-amino acids to afford the corresponding carbonyl compounds. Furthermore, FSM-16 proved to be re-usable by re-calcination at 450 degrees C after…
The process of obtaining alginate-chitosan fibres intended for medical applications was the subject of our investigations. Two methods of forming two-component alginate-chitosan fibres of the core-skin type (calcium alginate and chitosan respectively) were developed. The first method of forming fibres (A), which consi…
The valence state and the mesomorphic behaviour of a new cerium phthalocyanine double-decker complex bearing thioalkyl substituents are described and spectroscopic studies have revealed that the metal center in this lanthanide double-decker complex is tetravalent making the whole molecule neutral.
Degradation of porous low dielectric constant materials during their exposure in etch and strip plasmas is analyzed from point of view of surface chemistry and recombination of active radicals. Although the degree of damage during the etching can be significantly reduced, the damage in O2and H2based strip/cleaning pla…
New dissymmetrical neutral-cationic or anionic-cationic alpha,omega-diamido bolaamphiphiles have been synthesized in which the polar headgroups are derived from alginate and glycine betaine and which exhibit monolayer lipid membrane vesicles, large lamellae and rods.
History of structural ceramics study has been examined specifically proceeded in NGK. At the early time of the age, structural ceramics had been selected to aim the potential candidate material for the variety of heat engine to achieve the better fuel efficiency. Many kinds of the sciences and technologies had been in…
The physical properties of vitreous and amorphous silicon nanoparticles containing 300, 400, and 500 atoms are investigated by the molecular dynamics method. For a limited number of degrees of freedom, the internal energy of the amorphous phase is often less than the internal energy of the vitreous phase. The structur…
