Korosi erosi merupakan salah satu kerusakan yang sering terjadi pada sistem perpipaan akibat adanya pergerakan relatif fluida korosif dengan permukaan logam. Konsentrasi NaCl sangat mempengaruhi laju korosi pada suatu material. Kecepatan fluida yang relatif tinggi dan mengandung partikel akan menyebabkan erosi, dan ke…
Zn2SiO4:Eu3+, Dy3+ phosphors have been prepared through the sol-gel process. X-ray diffraction (XRD), thermogravimetric and ddifferential thermal analysis (TG-DTA), FT-IR spectra and photoluminescence spectra were used to characterize the resulting phosphors. The results of XRD indicated that the phosphors crystallize…
High luminescent intensity micro – nanometer Ca0.69Sr0.23(PxMoy)O4:0.05Eu3+ phosphor were synthesized by an innovative co precipitation-melted-salt (CPMS) method, Using Eu2O3, Ca(OH)2, SrCO3, HNO3, (NH4)6Mo7O244H2O, (NH4)2HPO4 and inorganic flux as raw materials, room temperature co precipitation and Melted-salt-calci…
Ce0.5Ti0.5O2 ion storage films were prepared by using sol–gel routes employed butyltitanate（Ti(OC4H9)4） and cerium nitrate（Ce(NO3)3•6H2O） as main initial materials. Structural, optical and electrochemical properties were investigated by XRD, SEM, cyclic voltammetry curves and utraviolet visible spectroscopy in this wo…
La0.95Sr0.05GaO2.975 has been prepared by conventional solid state reaction method. The calcined sample has been isostatically pressed into pellets at a load of 12 kN cm-2 and then sintered at 1400 °C for 12h. The crystalline phase formation and composition has been examined by X-ray diffraction (XRD) method. Dielectr…
Silicon nitride-based nanocomposites with different quantities (0, 1, 2 wt%) of multiwall carbon nanotubes (MWCNT) have been prepared by isostatic pressing. Abrasive tribological tests were carried out at room temperature in ambient atmosphere with various types of abrasives (different material and grain size) and lub…
La-modified Bi4Ti3O12 is a typical ferroelectric, piezoelectric and electro-optic material, having relatively low coercive field, low dielectric constant, high Curie temperature and high breakdown strength. Goal of the present research was to apply mixed oxide method for fabrication of BiTLax ceramics, study its chemi…
Στόχος αυτής της διπλωματικής εργασίας ήταν η ανάπτυξη ενός νευρωνικού ρυθμιστή, δηλαδή ενός ρυθμιστή που υλοποιείται με χρήση νευρωνικών δικτύων με σκοπό να επιτυγχάνεται η αυτόματη ρύθμιση μη γραμμικών συστημάτων σε ασταθείς περιοχές λειτουργίας. Τα νευρωνικά δίκτυα είναι ένας κλάδος της τεχνητής νοημοσύνης που εξελ…
A capacidade dos nanotubos de carbono penetrar nas celulas abriu a possibilidade da utilizacao dessas nanoparticulas no diagnostico e tratamento das neoplasias malignas. Contudo, pouco se conhece sobre o efeito dessas particulas nao funcionalizadas, ou seja, sem moleculas acopladas, sobre a resposta imune. Nesse estud…
Viscoelastic surfactant (VES) fluids are preferred for many applications in the oil industry. Their viscoelastic behavior is due to the overlap and entanglement of very long wormlike micelles. The growth of these wormlike micelles depends on the charge of the head group, salt concentration, temperature, and the presen…
The use of microsystems technology for the manufacturing of integrated on-wafer optical systems often leads to shape restrictions of the optical surfaces. To achieve full performance in integrated free-space optical systems, light propagation has to be controlled in two directions: In the plane of the wafer and perpen…
A strange self-sustained oscillation in plastic uniaxial tension of various materials is called the Portevin Le Chatelier (PLC) effect. In modelling PLC dynamic strain aging is the common way of explanation. It is based mainly on dislocation dynamics. Experimental studies show the negative strain rate dependence (NRS)…
Lead sulfide ( PbS ) quantum dots (QDs) capped with oleic acid and oleic amine were synthesized by using safe and innocuous sulfur powder as S source instead of the bis (trimethylsilyl) sulfide ((TMS)2S). QDs with size distribution from 20 nm to 3 nm were gained by controlling the experiment parameters such as heating…
In this paper, self-healing PUF microcapsules were prepared by in situ polymerization. The test results show that: 1) the ratio of core/wall material can had a significant effect on the average particle size of microcapsules. The ratio happens to be 1.0 to 1.0, best coating, relatively dense surface can be achieved. W…
Lipofilling ou enxerto de gordura é uma técnica muito utilizada para corrigir defeitos em qualquer região do corpo humano. O objetivo deste estudo foi analisar a segurança desta técnica para corrigir defeitos de reconstruções mamárias após câncer de mama. Foram analisados 158 pacientes que receberam 194 procedimentos…
This paper presents the effects of rate of heat extraction by groundnut, melon, palm kernel, shea butter and palm oils on the mechanical properties of various samples of pure commercial aluminium heat treated at 200°C, 250°C, 300°C and 350°C. Muffle furnace equipped with digital thermometer and thermocouple was used f…
According to the Sentmanat Extensional Rheometer (SER) and its Universal Testing Platform, a uniaxial tensile method and its device design scheme based on single rotary drum applied for polymer films is proposed in the paper, which will be used to characterize mechanical properties of various types of plastic films un…
Three ultrahigh molecular weight polyethylene (UHMWPE) composites of differing composition, reinforced with multiwalled carbon nanotubes (MWCNT) were prepared. The homogeneous distribution of MWCNT has been attempted by two dry blending methods and one melt-mixing process. The efficiency of the various methods was cha…
The tensile properties of basalt filament were measured and compared with these of E-glass fiber.
