We study a quasi-one-dimensional system of hard disks confined between hard lines to explore the relationship between the inherent structure landscape, the thermodynamics, and the dynamics of the fluid. The transfer matrix method is used to obtain an exact description of the landscape, equation of state, and provide a…
Abstract Zinc oxide (ZnO) nanoparticles possess antibacterial properties. Being less toxic to humans than silver, they are attractive as antibacterial agents in biomedical applications. In this study, we focus on the influence of the size of ZnO nanoparticles on their antibacterial action against strains of three bact…
Tissue-engineered constructs often fail due to poor integration with the patient's tissues. Specifically, they fail to be neovascularised, leading to the death and loss of the implanted tissues. Thus, there is a need to produce angiogenic materials to improve tissue integration. We describe the development of a layer-…
In this paper, we report novel superhydrophobic surfaces with tunable water adhesion by combining mussel-inspired surface chemistry and bioinspired multiscale surface structures. Highly ordered honeycomb porous films were prepared from a diblock copolymer polystyrene- block -poly( N, N -dimethylaminoethyl methacrylate…
This report concerns the remarkable fine structure reported recently in the optical absorption spectrum of the ubiquitous icosahedral Au 144 (SR) 60 cluster compounds when measured under cryogenic conditions. The theoretical explanation of the spectrum relied upon an I-symmetrized variant of the conventional Pd 145 -t…
4,4,4-tris(N-carbazolyl)-triphenylamine (TcTa) with low electron mobility are used as electron-blocking layer (EBL) for quantum-dot light-emitting diodes (QD-LEDs). With TcTa EBL, electrons are effectively blocked, while holes are efficiently injected; consequently, the developed QD-LEDs exhibit significantly improved…
To improve mechanical behaviors of silicon nitride ceramics, here we introduced a novel external field—vibratory pressure into the sintering of Si 3 N 4 ceramics with advantages of higher density, more uniform distribution of interfacial phase, higher sintering motivation in the width direction, and therefore more fav…
Vesicles based on mixed cationic and anionic surfactants (catanionic vesicles) offer a number of advantageous colloidal features over conventional lipid-based vesicles, namely spontaneity in formation, long-term stability, and easy modulation of size and charge. If biocompatibility is added through rational design of…
Size dependence of physical properties of nanodiamond particles is of crucial importance for various applications in which defect density and location as well as relaxation processes play a significant role. In this work, the impact of defects induced by milling of micron-sized synthetic diamonds was studied by magnet…
We develop high power magnetostrictive vibration power generator for battery-free wireless electronics. The generator is based on a cantilever of parallel beam structure consisting of coil-wound Galfenol and stainless plates with permanent magnet for bias. Oscillating force exerted on the tip bends the cantilever in v…
Biodegradable sizing agents from triethanolamine (TEA) modified soy protein could substitute poly(vinyl alcohol)(PVA) sizes for high-speed weaving of polyester and polyester/cotton yarns to substantially decrease environmental pollution and impel sustainability of textile industry. Nonbiodegradable PVA sizes are widel…
We employ adaptive mesh refinement, implicit time stepping, a nonlinear multigrid solver and parallel computation to solve a multi-scale, time dependent, three dimensional, nonlinear set of coupled partial differential equations for three scalar field variables. The mathematical model represents the non-isothermal sol…
A current overview of synchrotron radiation (SR) in macromolecular crystallography (MX) instrumentation, methods and applications is presented. Automation has been and remains a central development in the last decade, as have the rise of remote access and of industrial service provision. Results include a high number…
In recently synthesized two-dimensional superlattices of graphene and boron nitride, the atomic structure of the interface is complicated by a 2% lattice mismatch between the two materials. Using atomistic and continuum analysis, we show that the mismatch results in a competition between two strain-relieving mechanism…
The intercalation of amoxicillin trihydrate (AMOX) into layered zinc hydroxide (LZH) has been achieved via ion-exchange method. The resulted nanocomposite (AMOX-LZH) has been thoroughly characterised by a number of techniques including powder X-ray diffraction (PXRD), FT-IR spectroscopy, TGA/DTG analysis and scanning…
An invisibility cloak based on transformation optics often requires material with inhomogeneous, anisotropic, and possibly extreme material parameters. In the present study, on the basis of the concept of neutral inclusion, we find that a spherical cloak can be achieved using a layer with finite constant anisotropic c…
The precise arraying of functional entities in a reproducible and predictable way in morphologically well-defined shapes is a key challenge in materials science. In this work, we describe the importance of kinetic effects in the two-dimensional (2D) self-assembly of a negatively charged pyrene trimer ( Py 3 ) in aqueo…
We report on quantitative determination of the molecular weight distribution (MWD) and grafting density (σ P ) of polymer assemblies grown by controlled radical polymerization from flat substrates as a function of polymerization time and the ratio between the inhibitor and catalyst species. Specifically, we grow poly(…
Silver nanoparticles (AgNPs) are one of the most commonly used nanomaterials; however, it remains unclear whether AgNPs induce neurotoxicity. Here, we investigated the potential neurological effects of AgNPs and the neuroprotective effect of vitamin E (VE). We found that intranasal instillation of AgNPs in neonatal Sp…
A CO2-activated nanofluidic logic device, with imidazole-containing polymer grafted on the inner surface of the conically shaped nanochannels, exhibits high rectification ratio and fast response rate.
