After their service life is over, nuclear power plants must be decommissioned. Accordingly, Sweden has a system with segregated funds to cover the costs. Payments to the funds are dictated by the results of recurrent cost estimates. Recently, differences have been observed between different estimations for the Barsebc…

Tujuan penelitian ini adalah untuk mengetahui pengaruh asam terhadap pening…
The hexyl ester of 5-aminolevulinic acid (HAL) is an efficient inducer of the endogenous photosensitizer protoporphyrin IX (PPIX) in neoplastic tissue and approved for the fluorescence photodetection of bladder cancer. It is, however, limited to topical application due to unsuitable pharmacokinetic and pharmacodynamic…

Abstract The corrosion behavior of an Al–0.63Mg–0.28Si alloy under MgCl2 solution droplets with different initial concentration in environments of 33, 75, and 88% relative humidity (RH) was studied using a Kelvin probe. The available cathodic limiting current associated with oxygen reduction was highly dependent on th…
One of the concerned phenomena that influencing to the performance of electron beam mask writer is contamination of deflector. Previous studies show that the relation between the deflector contamination and pattern placement error. In fact, the source of the contamination of deflector was not defined clearly yet. Howe…
This paper presents results of the optimization of an EUV mask cleaning process and compares the results to data obtained on COG and EPSM masks using processes specifically designed for such masks. The key parameter investigated was cleaning efficiency, as measured in terms of Particle Removal Efficiency (PRE), CD shi…
Scanner expose condition is simulated to reproduce Chrome (Cr) migration on COG mask, known as a new type of mask degradation, with high energy fluency ArF acceleration tool. Contact hole size is decreased by forming rim inside sidewall of contact hole. CD change is observed as expose energy accumulates. Bridge defect…
Strict reticle critical dimension (CD) control is needed to supply ≤ 20nm wafer technology nodes. In front end lithographic processes for example, precise temperature control in resist baking steps is considered paramount to limiting reticle CD error sources. Additionally, current density during writing and focus are…
As an alternative to EUV lithography, ArF immersion multiple patterning lithography has been heavily employed in semiconductor fabrication. This situation has led to increase use of bright-field photomasks with floating small patterns. Latest CDSEMs are equipped with various charge compensation features and applicable…
Abstract Chrysanthemum‐like Co3O4 with nanorod assemblies is hydrothermally obtained from aqueous solutions of CoCl2 and urea (autoclave, 120 °C, 20 h, followed by calcination in air, 300 °C, 2 h).
Cellulose was dissolved at 3 wt % in 15 mL of 1-allyl-3-methylimidazolium chloride ([Amim]Cl) together with 2 wt % water, and then gas–liquid interface discharge was carried out at 20 W for 200 s. As a result, 7.6% of initially dissolved cellulose decomposed and 3.9% of initially dissolved cellulose changed into reduc…
In this study, bamboo activated charcoal was mixed with acrylic resin in various proportions and deposited on poly-ethylene terephthalate (PET) non-woven fabrics. A series of characterizations were carried out to estimate the performances of PET non-woven fabrics such as far infrared ray emission, heat retention, nega…
We present first MD simulation results of C 60 adsorption inside a single-walled carbon nanohorn. The assumed carbon nanohorn model and the values of the force field parameters lead to relatively good agreement between simulation and experiment. We show that the confinement of water and ethanol inside a carbon nanohor…
Liquid crystal polymer (LCP) has interesting characteristics that have garnered the attention of RF and microwave circuit designers. One major difference from typical high-frequency materials is that LCP is a thermoplastic. With LCP’s advent, engineers have discovered how to integrate high-performance electronics dire…

Selection of a most appropriate material is a very important task in design process of every product. There is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations and in making right decisions. This p…
This paper proposes a new foaming technology (solid-state foaming) to produce structural foams from waste thermosetting resins. The proposed technology is easy and does not require specific and expensive equipments. Solid tablets are produced by cold compaction of resin powder, and foam by heating in an oven. Composit…
A 3-D simulator of laser crystallization for polycrystalline-silicon thin-film transistors has been developed. Random nucleation, crystal growth velocity, latent heat emission, and partial crystallization are modeled, and a 2-D algorithm is extended to a 3-D algorithm. The$\mu$-Czochralski technique is analyzed using…
