The key challenges in thermoelectric power conversion are creating a significant temperature difference and obtaining more heat energy through a thermoelectric device. Herein, graphene/polyethyleneglycol composites (G-PEGs) were proposed as a heat supply for thermoelectric devices. The G-PEGs not only afford a lot of…
Surface modification of gold nanorods allows biocompatibility and complex architecture design for novel theranostic applications.
Although fluorescence offers ultrasensitivity, real-world applications of fluorescence techniques encounter many practical problems. As a noninvasive means to investigate biomolecular mechanisms, pathways, and regulations in living cells, the intrinsic heterogeneity and inherent complexity of biological samples always…
Dy-substituted nickel nanoferrites have been investigated in order to explore the possibility of Dy-for-Fe substitution in nickel ferrites, as well as the effect of the substitution on the microstructural and electrical properties. The samples were prepared by a simple citrate nitrate auto-ignition method. Rietveld an…
Graphene oxide (GO) nanosheets were easily covered with uniform metal-organic network films composed of tannic acid and Fe ions. The surface morphology of the wrapped GO sheets was elucidated using atomic force, scanning electron, and transmission electron microscopy measurements. The GO sheets covered with the TA-Fe…
Polymer-functionalized reduced graphene oxide (polymer-FG), produced as individually dispersed graphene sheets, offers new possibilities for the production of nanomaterials that are useful for a broad range of potential applications. Although non-covalent functionalization has produced graphene with good dispersibilit…
An excellent electromagnetic interference shielding effectiveness of ∼19.5 dB was measured for a 1 mm thick flexible few-layered graphene (FLG)/PVA composite sheet owing to the formation of network-like features by FLG in the PVA matrix.
Perylene-bisimides (PBIs) modified with tetraphenylethene (TPE) at N-terms show unique X-aggregation and are non-fluorescent in solution, aggregate and solid film due to the photoinduced charge transfer between TPE and PBI subunits.
NiTiO 3 thin films grown using a co-sputtering process exhibited well defined structural, morphological and optical characteristics, which showed enhanced visible light photocatalytic activity.
Tungsten disulfide (WS 2 ), with its transformation from indirect to direct band transitions when scaled down to a monolayer, exhibits great potential for future micro-device applications.
Effective deposition of MOFs on "inert" solid surfaces is very challenging. In this work, we found that polydopamine, which can be facilely and tightly formed on any types as well as any forms of solid surfaces, could be used as an effective nucleation center for MOF deposition. Based on this finding, various MOFs wer…
Europium doped silver tungstates α-Ag2-3xEuxWO4 (x = 0, 0.0025, 0.005, 0.0075 and 0.01 mol) were synthesized by the coprecipitation method at 90 °C for 30 minutes. These crystals were structurally characterized by means of X-ray diffraction (XRD), Rietveld refinement, and micro-Raman (MR) and Fourier transformed infra…
The luminescence of rare earths in CeO 2 is sensitized by intrinsic Ce 3+ ions.
The self-assembly of anionic kappa and iota carrageenan polysaccharides in the presence of NaCl, KCl and CaCl2 is studied by high-resolution atomic force microscopy (AFM). A hierarchical supramolecular chirality amplification over various length scales is observed upon the addition of KCl, whereas in the presence of N…
Cotton fabric was modified with 1,2,3,4-butanetetracarboxylic acid as cross-linking agent in the presence of sodium hypophosphite as catalyst.
Manganese oxides are shown to be applied materials including their use as efficient catalysts for various environmental applications.
In the latest years, researchers have been working to reduce the dependence on petroleum based fuels and products due to the increase in environmental consciousness. This leads to investigate the environmentally friendly sustainable materials in order to replace the existing ones. One of these polymeric materials is p…
Schematic illustration for the preparation of g-CNQDs though a thermal condensation process and CL of the g-CNQDs–K 3 [Fe(CN) 6 ] system.
Ampicillin, a common antibiotic, is detected at trace concentrations in milk using surface enhanced Raman spectroscopy in a microfluidic device, using less than 20 μL of sample, in 10 minutes, with minimal off-chip preparation. The device is configured so as to favor the interaction of the analyte with colloidal silve…
An all-solid-state flexible supercapacitor that achieves a high specific capacitance of 442.5 F g −1 was facilely synthesized based on a Co 3 O 4 @carbon nanotubes/polyindole composite.
