The primary barrier to wider commercial adoption of graphene lies in reducing the sheet resistance of the transferred material without compromising its high broad‐band optical transparency, ideally through the use of novel transfer techniques and doping strategies. Here, chemical vapour deposited graphene was uniforml…
CuO quantum dot-assembled nanospheres are fabricated by laser ablation of Cu plates in water.
EPDM rubber was exposed to an accelerated thermal aging environment produced by an air-circulating oven. The changes of morphology, mechanical properties of EPDM were monitored by scanning electron microscope (SEM), tensile/compressive testing. Crosslink density of EPDM was measured by the solvent swell method. The re…
The photoelectrical characteristics of field-effect phototransistors (FEPTs) are investigated experimentally based on a graphene–PbS quantum dot (QD) hybrid. The device presented a wide spectral response range from 300 to 1400 nm because of multiple-exciton generation of PbS QDs. The photoelectrical responsivity reach…
Imaging is one of the most direct and ideal ways to track drug loading distributions in drug carriers on the molecular level, which will facilitate the optimization of drug carriers and drug loading capacities. Herein, we report the mapping of an individual mesoporous calcium silicate hydrate (CSH) microsphere before…
The first examples of high-nuclear 3d-4f heterometallic clusters with mixed amino acid ligands are reported. Four 30-nuclear clusters {Ln6Cu24}(Ln = Gd, Tb, Pr and Sm) were obtained through the self-assembly of Ln(III), Cu(II) and mixed amino acid ligands of glycine (HGly) and β-alanine (HAla). The metal skeleton of c…
Chitosan synthesized locally with a degree of deacetylation 71% and chitosan with a degree of deacetylation 68% from Sigma Aldrich were used to investigate adsorption of Cu2+ ion in aqueous solution. The results obtained from equilibrium isotherm adsorption studies of Cu2+ ion were an-alyzed in five adsorption models…
The purpose of this article is to provide a systematic evaluation to perform characteristics on the thermal conductivity and thermal rectification of H-terminated graphene nanoribbons (HGNRs) with L pristine / L H-terminated = 1.
The surface enhanced Raman scattering (SERS) effect is explained using the interaction of a polarized molecule with its instantaneous image dipole in a metal surface. This model explains why SERS is obtained mostly on noble metals (Au, Ag), since these metals usually have lower inherent contamination as compared with…
In this study, we demonstrate the enhancement of the electrochromic performance of tungsten oxide (WO3) by crystal network topology modification. This is achieved by constructing various crystalline morphologies and patterns of the films. Different mesoscopic crystalline networks of WO3 were acquired on transparent co…
Synthesizing parameters of ZnO nanorods significantly affect the surface morphologies and further the performance of spirally hierarchical structure-based glucose sensors.
ZnO and CuO thin films were synthesized by a sol–gel and direct crystallization method on granular porous natural scoria respectively and CuO/ZnO/scoria was used for water treatment under visible light irradiation.
Poly( N -isopropyl acrylamide)-grafted SiO 2 hollow spheres loading vitamin C exhibited excellent temperature-controllable release, and their pyrolysis was studied.
We present the design, simulation, and measurement of a polarization-independent and angle-insensitive metamaterial absorber (MA) in X-band. Since the unit cell of the MA consists of four subwavelength split-ring resonators with 4-fold symmetric rotation, the MA is insensitive to the variation of both polarization and…
Chemical surfactants are used for efficient dispersion of nanoparticles (NPs) but they also cause a hazard to the environment.
This paper presents an original method to obtain, in one step, core/shell nanoparticles grafted covalently with polymer and functionalized with amino groups. By combining polyvinyl alcohol (PVA) and silica precursors, we were able to obtain silica‐coated and amino‐functionalized iron oxide nanoparticles (SPIONs) cross…
Electron transfer activities of metal clusters are fundamentally significant and have promising potential in catalysis, charge or energy storage, sensing, biomedicine and other applications. Strong resonance coupling between the metal core energy states and the ligand molecular orbitals has not been established experi…
Two novel bent-shaped π-organogelators 6a and 6b having different terminal pyridine rings as responsive sites were designed, synthesized and fully characterized. A subtle difference in the position of the N atom at the pyridine ring greatly affected their fluorescence and gelation properties. 6b showed remarkably stro…
By utilizing the energy transfer of Ce 3+ to Mn 2+ , the emitting colors can be adjusted from blue to red in Na 4 Ca 4 Si 6 O 18 :Ce 3+ ,Mn 2+ phosphors.
The first 8-connected 2D layer based on basket-liked {Sr⊂P 6 Mo 18 O 73 } cage was prepared, which exhibits high-efficient photodegradation ability for MB, RhB, and AP under visible and UV light, as well as bifunctional electrocatalytic behavior.
