The paper was presented on Oct. 10 and will be published in a special issue of Journal of Cellular Automata. There was some useful discussion following on the presentation, including amazement that I had computed some of the results by hand rather than using a computer.
This chapter uses a case study of two-dimensional electron gases in heterostructures to illustrate the theoretical concepts put forward in Chapters 7 and 8. The electrostatics and the field effect in these structures are worked out, and the capacitance between the electron gas and a top-gate is determined. Quantum mec…
A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer fibers with high specific surfaces for the collo…
Test structures for the electrical characterization of ultrathin conductive (ALD) films are presented based on electrodes on which the ultrathin film is deposited. The contact resistance of the buried electrodes to the ultrathin ALD TiN films is investigated using contact chain structures. This work includes test stru…
A suspension of sediment from a lagoon in a tap water production plant was collected for this experiment. The suspension was spray dried and calcined at 700 °C for 1 h. After calcining, 30 wt.% of the sediment were mixed with pottery clay. Samples with and without calcined sediment were sintered at 900, 1000 and 1100…
BACKGROUND: The analysis of the macromolecular tumour necrosis factor (TNF)-receptor interface helps to understand the antigenicity of this inflammatory protein. METHOD: The calculations are based on structural data from the protein database. The residues of the macromolecular interface are identified in the interface…
The objective of the research work is to afford the real applicability of UHTC materials to the manufacturing of new advanced hot structures designed for space applications providing, at the same time, non conventional characterization procedures specifically aimed at UHTC materials. Also objective of the work is to c…
\n Um dos maiores desafios da ortopedia moderna é recuperar o tecido ósseo que tenha sido perdido por motivo de doença ou acidente. Na busca de substitutos para os enxertos, tem-se utilizado comumente biomateriais para recuperação desse tecido. Um dos vários tipos de biomateriais usados são os preparados à base de col…
E very woman carries on her back, outside her rug, a basket made of a tough kind of rush, occasionally ornamented with stitches of various kinds. They also carry in the same way a bag formed of the tough inner bark of the acacia tree. Failing to procure this bark, which is the best for the purpose, they use the inner…
Thin TiN films have many important applications in Integrated Circuit (IC) technology. In spite of its chemical inertness, it is reported that TiN can be oxidized when exposed to oxidants (O2, H2O, etc.). To avoid an undesired oxidation of the metal-nitride layers, a study on this process is necessary. In this work, w…
Introduction Dynamic imaging, or tracking, of a “bolus” of intravascularly administered tracer can be interpreted to yield information both from the “first pass,” relating primarily to tissue perfusion, or from later “pseudo steady-state” phases, relating to transendothelial transport of the tracer between intravascul…
L'objectif de ce travail est de développer de nouveaux matériaux carbonés dont la structure poreuse est contrôlée en taille et en morphologie dès l'étape de synthèse. Nous nous sommes tout d'abord intéressés à la technique de nanomoulage. Nous avons, tout d'abord, cherché à optimiser les conditions de synthèse de la r…
In connection with the study of the phenomenon of drying, this work focuses on the study of slow evaporation of a liquid confined in a capillary of square cross section. In such a capillary, if the liquid wetting contact angle is low enough, liquid films are trapped by capillary forces along the capillary inside corne…

采用差示扫描量热仪、热重分析仪等研究了滑石粉作为成核剂对聚对苯二甲酸乙二醇酯（PET）结晶性能、热性能以及力学性能的影响。结果表明，滑石粉的添加量为0．5％（质量分数，下同）时，可有效改善PET的结晶性能，结晶温度（Tc）比经历相同热历程的PET空白试样提高11．36℃，且结晶完善程度随降温速率的减小而提高；非等温结晶动力学研究发现，Jeziorny法和莫志深法更符合复合材料的非等温结晶过程，而二次结晶的存在使Ozawa法并不适用；由于滑石粉与基体树脂相容性好并可均匀分散，从而很好地保持了原树脂的热性能，且所得复合材料的力学性能均有所提高，其中拉伸强度提高12％。
Coupled quantum dot systems exhibit the physics of artificial molecules with tunable properties. This chapter discusses the electrostatics of electrons in coupled quantum dots and the resulting charge stability diagram, the effects of finite tunneling coupling, and spin physics including hyperfine coupling. Related tr…
Carrier confinement in a high quality silicon volume has been proven to be a requirement for efficient silicon LEDs. Carrier injectors that are able to supply electron-hole pairs to the emitting volume without participating any further to non-radiative recombination play a fundamental role in achieving such a confinem…
In this article the impact of sidewalls, formed during reactive ion etching, on the electrical behavior of thin film structures is presented. The presence of sidewalls was experimentally characterized by sheet resistance measurements on Van der Pauw structures. The effect of these sidewalls on the extraction of specif…
The book provides a comprehensive treatment of combinatorial development of heterogeneous catalysts. In particular, two computer-aided approaches that have played a key role in combinatorial catalysis and high-throughput experimentation during the last decade - evolutionary optimization and artificial neural networks…
Conversion coefficients have been calculated for fluence-to-absorbed dose, fluence-to-effective dose and fluence-to-gray equivalent for isotropic exposure of an adult male and an adult female to (56)Fe(26+) in the energy range of 10 MeV to 1 TeV (0.01-1000 GeV). The coefficients were calculated using Monte Carlo trans…
