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 application of sensitizers to utilize visible light for chemical reactions is an established method. Several recent publications have impressively demonstrated the versatile use of visible light for various transformations, such as the conversion of alcohols to alkyl halides, and [2+2], [3+2], and [4+2] cycloadditions as well as carbon– carbon and carbon–heteroatom bond formations. The comb...

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...

Micro/nanomotors are capable of a wide variety tasks related, i.e., to biomedical or environmental applications. Light-driven semiconductor-based micromotors especially appealing, as they can split surrounding water via light irradiation, and therefore, move infinitely. However, their motion is typically limited in-plane with four degrees freedom (4DoF) even pseudo-1D 2DoF. Herein, magnetically...

Cadmium sulphide (CdS) quantum dot sensitized solar cells (QDSSCs) based on screen-printed TiO₂ were assembled using a screen-printing technique. The CdS quantum dots (QDs) were grown by using the Successive Ionic Layer Adsorption and Reaction (SILAR) method. The optical properties were studied by UV-Vis absorbance spectroscopy. Photovoltaic characteristics and impedance spectroscopic measureme...

Photoelectrode made of nanocable structure of ZnO nanorods (NR) coated with TiO(2) nanosheets (NSs) was investigated for CdS/CdSe quantum dot co-sensitized solar cells. ZnO NRs prepared solution reaction at 60 °C served as the backbone for direct electron transport in view of the single crystallinity of the ZnO NRs and the high electron mobility of ZnO semiconductor. Anatase TiO(2) NSs with the...

Oxygen-deficient TiO(2) nanowires show substantially increased donor density due to an increase in oxygen vacancies introduced intentionally by thermal treatment in ammonia, vacuum, or hydrogen. By coupling oxygen-deficient TiO(2) nanowires with CdS quantum dots, a significant enhancement in their photoactivities was observed in the entire wavelength region from 350 to 550 nm. These new nanocom...

The fabrication of reusable and biodegradation materials from renewable resources such as cellulose is essential for a sustainable world. The core-shell structured CdS-decorated TiO₂/Carbon microspheres (CdS/TiO₂/Carbon MS) photocatalyst was synthesized with controlled hydrolysis and a novel sonochemical method. It was prepared by using crosslinked microcrystalline cellulose as the core, tetrab...

  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...

Several attempted syntheses of Ti-TMS1, a hexagonal mesoporous TiO2 reported by Antonelli and Ying,1 have resulted in a lamellar structure as determined by twodimensional powder X-ray diffraction and transmission electron microscopy (TEM). Conventional one-dimensional powder X-ray diffraction patterns of the lamellar materials are similar to those reported for Ti-TMS1.1 Regions, of similar size...
