In this study, sea-urchin shaped Bi2S3/CdS hierarchical heterostructures are successfully synthesized via a convenient one-pot growth rate controlled route. The product is mainly composed of Bi2S3 nanorods and CdS nanoparticles grown on their surfaces. The formation mechanism was proposed based on the evolution of morphology as a function of solvothermal time, which involves fast formation of t...
The use of pharmacogenomics (PGx) in clinical practice still faces challenges to fully adopt genetic information in targeting drug therapy. To incorporate genetics into clinical practice, many support the use of Pharmacogenomics Clinical Decision Support Systems (PGx-CDS) for medication prescriptions. This support was fueled by new guidelines to incorporate genetics for optimizing drug dosage a...
Cuprous oxide (Cu2O) is an attractive photocatalyst because of its visible-light-driven photocatalytic behavior, abundance, low toxicity, and environmental compatibility. However, its short electron diffusion length and low hole mobility result in low photocatalytic efficiency, which hinders its wider applications. Herein, we report an in situ method to introduce nitrogen-doped carbon dots (N-C...
We present a detailed simulation based performance study of our recently proposed strong-neighborhood based connected dominating sets (SN-CDS) for mobile ad hoc networks (MANETs). We compare the performance of SN-CDS with that of the well-known minimum connected dominating sets (MCDS) and the ID-based connected dominating sets (ID-CDS) for MANETs. We show that by computing the SN-CDS involving ...
انتقال نفت واکس دار از نقاط سرد سبب کاهش حلالیت ترکیبات پارافینی در نفت و رسوب آنها بر دیواره لوله میشود. با بررسی ساختار رسوب، می توان فرایند سخت شدن رسوب را بررسی نمود. بررسی ساختار رسوب در لوله نشان دادکه بلورها با رشد لایه رسوب، از ساختار صفحهای به ناقص و گویچهای تغییر شکل مییابد. با مشاهده های انجام شده نسبت ابعادی بلورها در معادله پیش بینی نفوذپذیری رسوب تصحیح شد.
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...
