Resumen: La continua aparición de nuevas aplicaciones y formatos de almacenamiento, requiere ordenadores cada vez más potentes y una mayor cantidad de espacio de almacenamiento. Para controlar este tipo de datos y aplicaciones que ocupan cantidades ingentes de espacio en memoria, aparece la compresión. Con el objetivo de demostrar su utilidad, se ha desarrollado un prototipo de una aplicación p...

In this research, CdS nanoparticles and core/shell CdS/ZnS nanoparticles were prepared by using aqueous solution method and used 3-mercaptopropionic acid (MPA) as capping molecule. The effect of ZnS shell on optical and structural properties of CdS was investigated. X ray diffraction patterns of CdS nanoparticles at the room temperature and after heat treatment show zinc blende structure. X ray...

in this report, we present a facile approach for the synthesis of luminescent cds and cds:mn+2 nanocrystals by reaction of cdso4 and na2s2o3 in the presence of thioglycerol (c3h8o2s) as capping agent. the influence of various experimental variables including, ph values and percentage of dopant, on the growth rate and optical properties of the obtained cds nanocrystals has been systematically in...

BACKGROUND In determining whether clinical decision support (CDS) should be interruptive or non-interruptive, CDS designers need more guidance to balance the potential for interruptive CDS to overburden clinicians and the potential for non-interruptive CDS to be overlooked by clinicians. OBJECTIVE (1)To compare performance achieved by clinicians using interruptive CDS versus using similar, no...

The high-level contribution of this paper is a simulation-based comparison of two contrasting categories (minimum node size vs. stability) of connected dominating sets for mobile ad hoc networks. We pick the maximum density-based CDS (MaxD-CDS) and Node ID-based CDS (ID-CDS) to be representatives of the minimum node size-based CDS algorithms; the minimum velocity-based CDS (MinV-CDS) and the no...

  The basic requirements of the CdS thin films on their applications are high optical transparency, low electrical resistivity, and better crystalinity (e.g.high orientation). Firstly, we prepared CdS films by thermal eveporation techniques on glass substrate and then studied their photoconductivity from room temperature to 200 . Secondly, we prepared CdS films with impurities of Cu, Ag, Au and...

CdS thin films were deposited by thermal evaporation in a vacuum of ~ 10-5 torr at room temperature. Samples were subjected to annealing in the range of temperatures 100-300 oC for 1 hour in air.The crystal structure of CdS films was characterized by XRD technique. Only hexagonal phase with the preferred (002) plane was found in CdS films

In this work In2S3 and CdS nanoparticles were prepared by a simple hydrothermal method and then annealed at 500 °C for 2 h in an Ar gas until CdIn2S4(CdIS)-CdS nanocomposites were formed. Afterwards, efficiency of the as-synthesized CdIS-CdS nanocomposite in quantum dot-sensitized solar cells (QDSSCs) was evaluated. For this purpose, the as-prepared CdIS-CdS nanocomposites were deposited on TiO...

A new method in differentiation of chiral molecules is reported based on the fluorescence quenching of functionalized CdS quantum dots (CdS-QDs) as nanosensor by differing in the chirality of functionalization species. The chemically functionalized CdS-QDs with strong yellow emission were prepared using chiral L-cysteine (L-Cyst) and D-cysteine (D-Cyst) molecules. Then, the functionalized CdS-Q...

طی سال‌های اخیر، فرایند فتوکاتالیستی نیم‌رساناها برای حذف ترکیبات آلی از آب، توجه زیادی را به دلیل پتانسیل این فرایند به‌عنوان یک فناوری تصفیه کم‌هزینه و دوست‌دار محیط‌زیست به خود جلب کرده است. در این پژوهش با هدف به‌دست آوردن مقدار بهینه محتوای CuS و CdS در نانوفتوکاتالیست‌های CuS-CdS/TiO2، چهار نمونه با مقدارهای متفاوت CuS و CdS با روش آب گرمایی سنتز شدند. نمونه‌های سنتز شده با روش‌های XRD، F...
