In this work, a series of copolymer/silica nanocomposites are investigated that exhibit excellent anti-icing behavior and can be covalently grafted to any substrate containing C–H bonds with high durability.
The driving force of halide ions etching on Ag nanoprisms is the formation of a precipitant with Ag + at the [110] facet.
Surface silver atoms with upshifted d-orbitals are identified as the catalytically active sites in formaldehyde oxidation by correlating their activity with the number of surface silver atoms, and the degree of the d-orbital upshift governs the catalytic performance of the active sites.
Sub-100 nm Fe 3 O 4 particles have been synthesized via a solvothermal method by using water as a size-control agent. They show superparamagnetism, high magnetization, prominent biocompatibility, and great promising for magnetic resonance imaging.
Dolomite Clay was introduced in a traditional intumescent flame retardant system which contains ammonium polyphosphate/expandable graphite/melamine (APP–EG–MEL) to evaluate its effects on char morphology and fire performance. The effect of dolomite clay on the fire-resistance and thermal properties of expandable graph…
The assembly of proteins into various nano-objects with regular and periodic microstructures, i.e. protein arrays, is a fast-growing field in materials science. Due to the structural complexity of proteins, reports in this field are still quite limited. In this review, we summarize the recent developments in protein a…
Schematic of the synthesis of Ni/NiO magnetic nanoparticles organized in film form by a dead organic matrix of yeast.
Recently discovered atomically thin black phosphorus (called phosphorene) holds great promise for applications in flexible nanoelectronic devices. Experimentally identifying and characterizing nanomechanical properties of phosphorene are challenging, but also potentially rewarding. This work combines for the first tim…
The last few years have witnessed a great shift in research from conventional 2D materials and TMDCs (transition metals dichalcogenides) to new single element 2D materials, apart from Graphene. Among these, black-phosphorus (or phosphorene) was mostly investigated mainly due to appropriate mobility, bandgap tunability…
Herein we report development and validation of the method for evaluating the encapsulation efficiency of a micelle-based nanosystem composed of irinotecan hydrochloride (CPT-11) and an amphiphilic molecule DSPEmPEG2000. The results showed that the centrifugation method can be used for separation of free drug, a critic…
The effectiveness of thermoelectric (TE) materials at converting heat gradients into electricity, and vice versa, is quantified by the dimensionless figure of merit, ZT. Current TE materials, such as Bi 2 Te 3 and PbTe, have ZT values of approximately 1, but contain highly toxic and/or rare elements, which limits thei…
Thermally-Induced Dopant Segregation Effects on the Space Charge Layer and Ionic Conductivity of Nanocrystalline Gadolinia-Doped Ceria, Bae, Jiwoong, Lim, Yonghyun, Park, Jun-Sik, Lee, Dohaeng, Hong, Soonwook, An, Jihwan, Kim, Young-Beom
Viologen-tryptophan ternary complexation inside CB[8] is used to prepare a supramolecular polymer which show redox controlled transformation from homo polymer to hetero polymer.
In this study, CdTe/CdSe NCs BNH solar cells with PCE of 6.25% were successfully fabricated in an inverted structure configuration ITO/ZnO/CdSe/CdSe:CdTe/CdTe/Au by a solution process.
Sustainability of thermoelectric parameter in operating temperature range is a key consideration factor for fabricating thermoelectric generator or cooler. In present work, we have studied the stability of thermoelectric parameter of Cu2Se within the temperature range of 50-800°C. Temperature dependent Seebeck coeffic…
The effect of both a RF sputtered Al-doped ZnO (AZO) thin film seed layer onto a FTO/glass substrate and its growth time onto the morphological, structural and optical properties of the resulting electrochemically grown ZnO nanorod arrays (NRAs) have been studied. ZnO NRs grown onto the different AZO seed layers exhib…
A facile, highly sensitive “turn on” SERS nanosensor for the detection of glucose in urine has been developed based on the aggregation of the 4-mercaptophenylboronic acid decorated silver nanoparticles in the specific bonding to glucose.
Polymer nanocomposites filled with carbon nanotubes are observed to present an onset of the insulator-to-conductor transition through previous experimental studies. In this work, numerical simulations based on Monte Carlo method are performed to investigate the percolation threshold. The conductive fillers are modeled…
Butterfly-shaped tetrabenzo[a,c,g,i]fluorene (TBF)-based molecules (1 and 2) were designed, synthesized and well characterized using various spectroscopic techniques. The single crystal X-ray structure of 1 shows the presence of intermolecular 3-D π-π stacking interaction and unprecedented "cold crystallization" in po…
In this study, Ti-mineral superfine powders (Ti-MSP) encapsulated in urea-formaldehyde resin microcapsules (Ti-MSP@UF-MC) were successfully prepared via a one-step microemulsion method for the first time. Because of the strong confinement effects, the Ti-MSP@UF-MC possessed perfect microwave heating effects. The tempe…
