In this paper, we present a simple method for preparation of graphene-ZnO nanocomposites (G-ZnO). The method is based on thermal treatment of the graphene oxide (GO)/ZnO paste which reduces the graphene oxide into the graphene and leads to the formation of the G-ZnO nanocomposite. The structure, morphology and optical properties of synthesized nanocomposites are characterized with XRD, FESEM, F...

Photocatalytic H 2 production from water splitting is an effective method to solve energy crisis and environmental pollution simultaneously. Herein, carbon@CdS composite hollow spheres (C@CdS-HS) are fabricated via a facile hydrothermal using porous carbon (C-HS) as the template. The C@CdS-HS shows excellent photocatalytic -generation rate of 20.9 mmol h ?1 g (apparent quantum efficiency 15.3% ...

Since their discovery, carbon dots (CDs) have been a promising nanomaterial in variety of fields including nanomedicine. Despite potential this area, there are many obstacles to overcome for CDs be approved biomedical use. One major hindrance CDs’ approval is related poorly defined structure. Herein structural study presented order rectify shortcoming. The properties three which significant pro...

An extractive bioconversion with Bacillus cereus cyclodextrin glycosyltransferase (CGTase, EC 2.4.1.19) in aqueous two-phase system (ATPS) was investigated for the synthesis and recovery of cyclodextrins (CDs). Optimum condition for the extractive bioconversion of CDs was achieved in ATPS consisted of 7.7% (w/w) polyethylene glycol (PEG) 20,000 and 10.3% (w/w) dextran T500 with volume ratio (VR...

Mature messenger RNAs (mRNAs) consist of coding sequence (CDS) and 5' and 3' UTRs, typically expected to show similar abundance within a given neuron. Examining mRNA from defined neurons, we unexpectedly show extremely common unbalanced expression of cognate 3' UTR and CDS sequences; many genes show high 3' UTR relative to CDS, others show high CDS to 3' UTR. In situ hybridization (19 of 19 gen...

The connected dominating set (CDS) has been generally used for routing and broadcasting in mobile ad hoc networks (MANETs). To reduce the cost of routing table maintenance, it is preferred that the size of CDS to be as small as possible. A number of protocols have been proposed to construct CDS with competitive size, however only few are capable of maintaining CDS under topology changes. In thi...

We have successfully demonstrated the use of capped carbon dot systems, namely, CDs/ β -cd, CDs/LMH, and CDs/Suc, as fluorescent sensors for the detection of hemin. The capped carbon dot systems showed quenching of PL intensity in the presence of hemin. The minimum detection limit was determined to be ~1 μ M. The PL response with free Fe(II) and Fe(III) was also studied. It was observed that PL...

A newly developed CdS/rGO/CC electrode was prepared based on a flexible carbon cloth (CC) substrate with cadmium sulfide (CdS) nanoparticles and reduced graphene oxide (rGO). The CdS was synthesized using an aerosol-assisted chemical vapor deposition (AACVD) method, and the graphene oxide was thermally reduced on the modified electrode surface. The existence of rGO in the CdS-modified electrode...

BACKGROUND Clinical decision support (CDS) for primary care has been shown to improve delivery of preventive services. However, there is little evidence for efficiency of physicians due to CDS assistance. In this article, we report a pilot study for measuring the impact of CDS on the time spent by physicians for deciding on preventive services and chronic disease management. METHODS We random...
