Green synthesis of thermally stable Ag-rGO-CNT nano composite with high sensing activity

Construction of Er3+:YAlO3/RGO/TiO2 Hybrid Electrode with Enhanced Photoelectrocatalytic Performance in Methylene Blue Degradation Under Visible Light

“…The grain sizes of T, ET, RT and ERT were 8.9, 9.8, 11.1 and 9.9 nm, respectively. These values were estimated from the diffraction peak widths in the XRD patterns using the Scherrer equation and were consistent with the scanning electron microscopy (SEM) results for ERT. For RGO, the characteristic diffraction peak of the prepared GO in the experiment at 10.8° (see Supporting Information) was not detected, while peaks at 24.7° and 43.5° assigned to the (203) and (101) crystal planes of carbon were observed .…”

Synthesis, Characterization, and Electrochemical Performance of rGO-MWCNT/Mn-Co-Cu Nanohybrid as Novel Catalyst for Methanol Electrooxidation

“…In this process, the functionalities on the surface of GO were reduced, and rGO-MWCNT support material was obtained. 58 A hydrothermal method was employed to prepare oxide composites. 59 To synthesize trimetallic composites, 2 mmol of CoSO 4 •7H 2 O, 2 mmol of CuSO 4 •5H 2 O, and 2 mmol KMnO 4 with 20 mmol of NaSO 4 were sonicated in 100 mL of water for 30 min and sealed in a Teflon-lined autoclave at 160 °C for 10 h. The resulted precipitate was filtered, washed with water, and dried at 80 °C.…”

A Fluorescence System Composed of Nitrogen-doped Graphene Quantum Dots and Gold Nanoparticles Coated With Phenylalanine for Selective and Sensitive Quantification of Piroxicam in Biological Samples

“…Fluorescence resonance energy transfer (FRET), introduced as a technology in uorescence methods in which energy can be transferred from uorophore as a donor to an acceptor via dipole-dipole coupling process [10,11]. This technique has been successfully utilized for the detection of different biological molecules [12][13][14] and ions [15,16], but there is no report on the use of this method for the determination of piroxicam. In the design of a FRET system, the selection of proper donor-acceptor pairs is important for the achievement of good e ciency.…”
