As a bubble moves near different boundaries, the motion characteristic will change largely compared with the condition of free field, especially near the free surface: there will appear a complex phenomenon because of the interaction. This paper aims to investigate experimentally the phenomenon and the regularity of t…
Silver nanoparticles (AgNPs) are attracting attention due to their anti-microbial activity and consequently used in possible biomedical applications. The present study has evaluated the efficacy of biosynthesized AgNPs using Acanthophora spicifera against five prominent biofilm forming pathogens using microtitre plate…
The effect of Cd on the corrosion-resistant behavior and mechanical performance of Mg using gas collection, electrochemical measurements and tensile stress tests has been investigated. The experimental results showed that in the cathodic polarized region, hydrogen evolution and magnesium hydride formation were signifi…
Nanographite flake through ultrasound dispersing expanded graphite which got by chemical oxidation and microwave puffing method have been prepared by natural flake graphite. The microstructures of natural flake graphite, expanded graphite and nanographite sheets were characterized by means of SEM, XRD, FTIR and Raman;…
We report the facile and scalable synthesis of a highly monodispersed inorganic nanostructure based on well-designed Gd(OH)3 nanorods. X-Ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), as well as energy-dispersive spectroscopy (EDS) were applied to characterize the sa…
The number of potentially relevant materials resulting from the aggregation of elementary units with a finite functionality continues to increase. The growth of branched clusters and networks may proceed through the formation of reversible (physical) or irreversible (chemical) bonds. The kinetics of bond formation is…
The relationship between coercivity and the microstructural parameters α and Neff for grain refined Nd–Fe–B sintered magnets was examined. The parameter α describes the effect of grain misalignment and a decrease in the magnetocrystalline anisotropy of the Nd2Fe14B grains on the coercivity. The parameter Neff describe…
A novel nano-fibrillated mesoporous carbon (IFMC) was found to be an effective modifier in combination with ionic liquid 1-octylpyridinum hexafluorophosphate (OPFP) as a binder to give impregnated graphite electrodes with outstanding electrochemical performances.
The recent needs in the nanosciences field have promoted the interest towards the development of miniaturized and highly integrated devices able to improve and automate the current processes associated with efficient nanomaterials production. Herein, a green tape based microfluidic system to perform high temperature c…
We study a sixth order Cahn--Hilliard type equation that arises as a model for the faceting of a growing surface. We show existence of global-in-time weak solutions in two space dimensions, assuming periodic boundary conditions. We also establish exponential-in-time a priori estimates on the $H^3$ norm of solutions. T…
We demonstrate a simple approach to prepare hairy polymer nanorods/nanofibres by exploiting the self-assembly behavior of block copolymers. The hairy nanofibres were prepared from an asymmetric polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer whose self-assembled morphology consisted of PS cylinders…
The synthesis and characterization of bare silica (4 nm in diameter) nanoparticle-attached meso-tetra(N-methyl-4-pyridyl)porphine (SiO(2)-TMPyP, 6 nm in diameter) are described for pH-controllable photosensitization. Distinguished from organosilanes, SiO(2) nanoparticles were functionalized as a potential quencher of…
At room temperature, gold nanoparticles were atomically dissolved in the presence of aromatic thiols and regenerated from the solution by treatment with H(2)O(2), and the process is reversible. Moreover, the formed Au-thiol compounds have been demonstrated to be a powerful elemental building block for engineering vari…
Reactive poly(methacrylate)-based polymer brushes with radically exchangeable alkoxyamine units in the side chains were prepared on flat silicon substrates and their reactivity and surface properties were investigated. The reactive polymer brushes were prepared by surface-initiated atom transfer radical polymerization…
We present a facile method for the preparation of bimetallic AuAg nanoparticles (NPs) with controlled size and composition rendering them ideally suitable for optical and catalytic applications. In analogy to methods for the generation of monometallic Au and Ag NPs, AuAg NPs were prepared inside polystyrene-b-poly(4-v…
Crystalline double perovskite La2BMnO6 (B = Ni and Co) nanoparticles with an average grain size of ∼64 nm were successfully prepared using a facile, environmentally friendly, scalable molten-salt reaction at 700 °C in air. Their composition and structural and magnetic properties have been characterized.
The novel ultra low dielectric constant poly(ether ether ketone) hybrid films in which nanoscale phosphotungstic acid (PWA) clusters were grafted onto the side chains of poly(ether ether ketone) containing (3-trifluoromethyl) phenyl groups and carboxyl groups (PEEK–CF3–COOH) in the presence the silane coupling agent γ…
A novel drug delivery system of doxorubicin (DOX)-loaded Zein in situ gel for interstitial chemotherapy was investigated in this study. The possible mechanisms of drug release were described according to morphological analysis by optical microscopy and scanning electronic microscope (SEM). In vitro and in vivo anti-tu…

The critical challenge for preparing carbon nanotube (CNT)/polymer nanocomposites is how to create a strong interfacial binding energy (IBE) between the polymer matrix and the CNT. Molecular dynamics simulations of nylon 6 melts and its composite with pristine CNT or functionalized CNT embedded have been performed. Th…
