Figure S1. Time‐dependent UV‐vis absorbance spectra of the MO solution in the presence (a) TiO2; (b) BiOI/TiO2‐C10; (c) BiOI/TiO2‐C20; (d) BiOI/TiO2‐C30; (e) mechanical mixture of BiOI and TiO2 (M‐BT) under UV light irradiation; (f) EDX of BiOI/TiO2‐C30 (Bi:Ti = 0.4:1).
Nanostructured photoanodes were prepared via a novel combination of titanium dioxide (TiO2) nanoparticles and mesoporous carbon (C). Four different photoanodes were synthesized by sol-gel spin coating onto a glassy substrate of fluorine-doped tin oxide. The photocatalytic activities of TiO2, TiO2/C/TiO2, TiO2/C/C/TiO2, and TiO2/C/TiO2/C/TiO2 photoanodes were evaluated by exposing the synthesize...
The objective of this article is to prepare a time-inhomogeneous intensity model for valuing cash-flow CDOs, which explicitly incorporates the credit rating of the firms in the collateral portfolio as the indicator of the likelihood of default. Our model can prove very useful for the pricing, structuring, rating and risk management of CDO notes, whenever the legal structure of the transaction, ...
The wettability of reactively sputtered Y₂O₃, thermally oxidized Y-Y₂O₃ and Cd-CdO template assisted Y₂O3 coatings has been studied. The wettability of as-deposited Y₂O3 coatings was determined by contact angle measurements. The water contact angles for reactively sputtered, thermally oxidized and template assisted Y₂O3 nanostructured coatings were 99°, 117° and 155°, respectively. The average ...
There are only two known thiol dioxygenase activities in mammals, and they are ascribed to the enzymes cysteine dioxygenase (CDO) and cysteamine (2-aminoethanethiol) dioxygenase (ADO). Although many studies have been dedicated to CDO, resulting in the identification of its gene and even characterization of the tertiary structure of the protein, relatively little is known about cysteamine dioxyg...
We present a new approach to price CDOˆ2-type transactions consistently with the pricing of the underlying CDOs. We first present an extension to the current market standard model using a Gaussian mixture (GM) copula model instead of one parameter single Gaussian Copula model. It shows that GM broadly captures the correlation skew shown in the index tranche market, but not exactly and across ti...
The Cdo-p38MAPK (p38 mitogen-activated protein kinase) signaling pathway plays important roles in regulating skeletal myogenesis. During myogenic differentiation, the cell surface receptor Cdo bridges scaffold proteins BNIP-2 and JLP and activates p38MAPK, but the spatial-temporal regulation of this process is largely unknown. We here report that KIF5B, the heavy chain of kinesin-1 motor, is a ...
Objective The objective of the study was to determine whether the cadmium-derived materials induce intracellular protein citrullination. Methods Human A549 lung epithelial cells were exposed to cadmium in soluble and nanoparticulate forms represented by cadmium chloride (CdCl2) and cadmium oxide (CdO), respectively, and their combinations with ultrafine carbon black (ufCB) produced by high te...
نانوذرات در چند سال اخیر به دلیل خواص فیزیکی و شیمیایی منحصر به فرد خود که با خواص شان در حالت حجمی متفاوت هستند، از توجه زیادی برخوردارند. تلاش های زیادی در تهیه ی نانوذرات اکسید کادمیوم به روش های مختلف از جمله: مکانیک- شیمیایی و شیمیایی انجام شده است. در این پایان نامه از دو روش برای تهیه ی نانوذرات cdo استفاده شده است. کم ترین مقدار اندازه ی ذرات تهیه شده با روش شیمیایی به دست آمد. آنالیز ح...
We propose a stable non-parametric algorithm for the calibration of pricing models for portfolio credit derivatives: given a set of observations of market spreads for CDO tranches, we construct a risk-neutral default intensity process for the portfolio underlying the CDO which matches these observations, by looking for the risk neutral loss process ’closest’ to a prior loss process, verifying t...
