Summary The effect of the plasticizer content (mixture of water and glycerol) on the cellular structure of the considered material and its influence on the resulting properties, such as mechanical stiffness, are investigated by means of optical microscopy, X‐ray diffraction, thermogravimetry and standard mechanical te…
Abstract Self‐consistent modeling of dust particle kinetics and multi‐fluid multi‐species transport of boundary plasmas in ITER is performed with the multi‐physics code DUSTT/UEDGE. Results are presented for the sensitivity of the pedestal and divertor plasmas to the injection rate, size, and source location of the du…
Efficient capture of sunlight remains one of the great challenges to photovoltaics today. This is particularly so for the dominant photovoltaic material - crystalline silicon - which, as an indirect gap semiconductor, needs several hundred micrometers thickness for efficient operation. This paper gives an overview of…
We apply retrospective cost adaptive control (RCAC) to a command-following problem for uncertain Hammerstein systems with Duhem hysteresis nonlinearities. The only required modeling information of the linear plant is a single Markov parameter. We numerically investigate the sense in which RCAC achieves internal model…
We have successfully synthesized three-dimensional (3D) hierarchical ZnO nanostructure through a simple hydrothermal synthetic approach, namely nanoflowers. We have also studied the growth process of nanoflowers based on a series of experiments. In addition, the comparative photocatalytic studies showed the photocatal…
Crystallization is a major separation process in the pharmaceutical industry. Most crystallizations are performed batchwise, but there is great incentive for switching to continuous operation. We have investigated the modeling, simulation, optimization, and robustness of a multi-segmented, multi-addition plug-flow cry…
Die Lebensdauer abrasiv beanspruchter Bauteile kann durch Beschichtungen verlängert werden. Für die Herstellung dicker Schichten sind das Auftragschweißen und nunmehr auch das induktive Beschichtungsverfahren geeignet. Beide Technologien werden verglichen. Verfahrens- aber auch werkstofftechnische Aspekte helfen, die…
In the TC4 titanium alloy subject to high pulsed magnetic field, the phase transformation from α to β occurs. When the magnetic induced intensity increased from 2T, 3T to 4T with constant 30 pulses, the percent of α phase adds up gradually. When the magnetic induced intensity is 4T the volume fraction of α phase amoun…
Abstract Preliminary TECXY code simulation results of scrape‐off layer conditions in DEMO1 reactor design are presented. The values for snowflake (SF) and single null divertor configurations are discussed. The SF divertor configuration used here, although not fully optimised yet, already promises better performance th…
Although BSA Au clusters fluoresce in red region (λmax: 650 nm), they are of limited use due to low fluorescence quantum yield (~6%). Here we report an enhanced fluorescence imaging application of fluorescent bio-nano probe BSA Au clusters using multipulse excitation scheme. Multipulse excitation takes advantage of lo…
The ceramic industry, and others industries of manufacturing and transformation of materials produce, in greater or lesser degree, a quantity of waste that are not reused or doesn’t have a destination ecologically correct. Finding a correct destination for this kind of materials comes being a big tool for society nowa…
Ca x Zn (1-x) Al 2 O 4 thin films (x = 0.00; 0.05; 0.10; 0.15 and 0.20) were prepared by sol-gel method with the substitution of Zn 2+ by Ca 2+ in the framework of ZnAl 2 O 4 . The effect of Ca addition on the structure and morphology of CaZnAl 2 O 4 thin films was investigated by x-ray diffraction ( XRD), field-emiss…
This paper aims to apply a thermal treatment of beech and spruce sawdust dried to 10% moisture in order to determine the mass loss and to obtain pellet sets. This paper considers the colour change of the treated material during the treatment, as function of time and temperature increase. It also highlights the changes…
In this study, we investigated the electrical, optical and structural properties of aluminum-doped ZnO (AZO) thin films by RF magnetron sputtering under different working pressure of 5 - 40 mTorr. Optimization of the prepared thin films shows low resistivity of 6.11 × 10-4Ω-cm, mobility of 4.295 cm2/V-s and carrier co…
Abstract A 31‐inch FHD (1920times1080) AM‐OLED TV was developed by using a‐IGZO TFTs. Co‐planar type of a‐IGZO TFT was fabricated at Gen 4.5 glass substrate with IGZO (1:1:1) AC sputtering system for AM‐OLED. We also used Fine Metal Mask (FMM) for R,G,B sub‐pixel arrangement.
Ultrathin Cu(In,Ga)Se2(CIGS) films were deposited by 1-stage, 2-stage and 3-stage co-evaporation processes. In situ, real time spectroscopic ellipsometry (RTSE) was used to study the growth dynamics of the ultrathin CIGS films. Time dependent surface roughness layer (ds) and bulk layer (db) thicknesses were extracted…
Based on a modified form of Archard’s wear theory, significant data were obtained using the finite element analysis code DEFORM during the process of warm extrusion, including instantaneous interface temperature, sliding velocity, and interface pressure distribution of every node. From the acquired data, the wear of t…
Cuprous oxide is deposited on various substrates such as stainless steel (SS), Cr-Au (20-100 nm) coated SS, fluorine doped tin oxide on glass (FTO-G), Cr-Au (20-100 nm) coated FTO-G and Ga doped ZnO (GZO) through potentiostatic electrodeposition method. A wide range of potential is used for deposition and all the resu…
The need for photovoltaic coverglass coatings that are both broadband antireflective and omni-directional has led to the development of biomimetic moth-eye type graded index of refraction surfaces. In this study, we evaluate generic nanostructured coatings derived using both top-down and bottom-up approaches. It is fo…
Investigation on polycrystalline electroceramics involves the synthesis, the consolidation and the analysis of the electrical behavior, along with careful evaluation of the final microstructure. The synthesis of ceramic powders with controlled characteristics is crucial in the study of materials with optimized propert…
