A method is described for the in situ growth of substrate-supported organized gold nanoparticles. Upon exposure to an aqueous solution of a gold salt and a mild reducing agent, the particle size can be significantly increased without any loss of superstructure organization. Furthermore, no secondary nucleation is obse…
We report a development of graphene tunnel junctions made by chemical vapor deposition grown graphene and sputtered aluminum insulating by an in-situ grown aluminum oxide. The thin oxide layer formed in between the metal layer and the two-dimensional material is a crucial part of a tunnel junction. We characterized su…
It has been shown that selected types of substituents are able to vary the oxidative behavior of multi-walled carbon nanotubes. Such substituents investigated were sterically hindered secondary amino groups bonded in grafted piperidine units and covalently bonded bromine groups. Their interference and activity was pre…

Monodisperse polydopamine capsules with thin shells are synthesized by dopamine polymerization using toluene emulsion droplets as templates. Aqueous emulsions of monodisperse toluene droplets stabilized by the anionic surfactant sodium dodecyl sulfate are prepared by use of Shirasu porous glass membrane emulsification…
Fluorite structured oxides are used in numerous applications and as such it is necessary to determine their materials properties over a range of conditions. In the present study we employ molecular dynamics calculations to calculate the elastic and expansivity data, which are then used in a thermodynamic model (the cB…
The existing prediction methods of penetration depth do not take the influence of attack angle or angular velocity of projectile (i.e. effect of attack angle) into account. The main purpose of this work is to develop an approximate approach to predict the penetration depth for a rigid projectile into concrete target c…
Optical properties of graphene oxide (GO) dispersed in aqueous medium with aging and pH variations were investigated along with concurrent changes of oxygen functional groups of GO. Freshly prepared GO exhibit strong excitation wavelength dependent luminescence, which gets gradually nullified with aging due to the dra…
The electronic and magnetic properties of La2/3Sr1/3MnO3(LSMO)/tetragonal BiFeO3(BFO) heterostructures with the xy-plane biaxial strain were investigated by first-principles calculations. As the xy-plane lattice constant is ranging from 3.619 to 3.921 Å, a large interfacial magnetoelectric coupling (IMEC) appears in t…
An accurate modelling of catalytic growth of carbon nanotubes (CNTs) is needed to model the physics of carbon adsorption and diffusion into the catalyst surface along with the catalyst deactivation. The model should be able to provide a physical response towards the change of temperature and partial pressure. Though t…
In a previous work (Nicu et al. 2013), the flocculation efficiency of three chitosans differing by molecular weight and charge density were evaluated for their potential use as wet end additives in papermaking. According to the promising results obtained, chitosan (single system) and its combination with bentonite (du…
Abstract We study the optical response of monodisperse colloids of core-shell plasmonic nanoparticles and introduce a computational approach to optimize absorption for photothermal applications that require dilute colloids of non-interacting particles with a prescribed volume fraction. Since the volume fraction is hel…
The tunable electrical properties of reduced graphene oxide (rGO) make it an ideal candidate for many applications including energy storage. However, in order to utilize the material for applications it is essential to understand the behavior of the material on the nanoscale, especially how naturally occurring phenome…
ABSTRACT Novel renewable thermoplastic elastomers were synthesized by sequential polymerization of lysine‐ and itaconic acid‐derived monomers. Ring‐opening polymerization of lysine‐based O ‐carboxyanhydride monomer using diethylene glycol as an initiator gave well‐defined α,ω‐dihydroxy functionalized lysine‐derived po…
High Resolution Image Download MS PowerPoint Slide Two types of out-of-substrate Ag–Ag 2 O nanoplates were grown on a ZnO substrate through a surfactantless photochemical method. First, the in situ photochemically synthesized Ag–Ag 2 O nanoparticles further crystallized into nanoplate-like superstructures with rough s…
We have been developing surface functionalization of various nanoparticles including nanodiamond and iron oxide nanoparticles in view of biomedical applications. In this context, TiO2 nanoparticles (TiO2 NP) are functionalized with polyglycerol (PG) to provide water-dispersible TiO2–PG, which is further derivatized th…
Abstract The quasibinary section of the intermetallic phases MAl 4 and MGa 4 with M=Sr and Ba have been characterised by means of X‐ray diffraction (XRD) studies and differential thermal analysis. The binary phases show complete miscibility and form solid solutions M(Al 1− x Ga x ) 4 with M=Sr and Ba. These structures…
To endow suitable anti-corrosion property in simulated body fluid for biological carbon/carbon composites (CC), a composite coating consisted of SiC inner-layer and hyaluronic acid(HYA)-Sr doped dicalcium phosphate dehydrate (SD) outer-layer was fabricated on CC. The morphology, microstructure and corrosion resistance…

In this paper, a series of polyazomethines (PAZs) were prepared using dihydroxy substituted Schiff bases and 1,4-diiodobenzene. Also, different group effect such as methylene carbon and etheric oxygen bridges on photophysical, electrochemical, conductivity and thermal properties were clarified. The new polymeric mater…
