Silicon nanowires (SiNWs), as a novel one-dimensional semiconducting nanomaterial, are attracting increasing interest in recent years. The synthesis of SiNWs with in situ grown silver nanoparticles (AgNPs) (SiNWs@AgNPs) is reported and the highly effective and long-term antibacterial activity of this novel nanostructu…
A facile and sustainable synthesis of hollow carbonaceous nanospheres is presented, offering a scalable and multifunctional route to the generation of useful nanocontainers, which critically possess the stability not offered by polymeric equivalents and functionality not afforded by other nanocarbons. Carbonization te…
The adsorption of neutral (poly)-aromatic, antiaromatic, and more generally π-conjugated systems on graphene is studied as a prototypical case of π−π stacking. To account for dispersive interactions, we compare the recent van der Waals density functional (vdw-DF) with three semiempirical corrections to density functio…
Different stoichiometric configurations of graphane and graphene fluoride are investigated within density-functional theory. Their structural and electronic properties are compared, and we indicate the similarities and differences among the various configurations. Large differences between graphane and graphene fluori…
The present study demonstrates an eco-friendly and low cost protocol for synthesis of silver nanoparticles using the cell-free filtrate of Aspergillus flavus NJP08 when supplied with aqueous silver (Ag+) ions. Identification of the fungal isolate was based on nuclear ribosomal DNA internal transcribed spacer (ITS) ide…
Metal nanocrystals with highly branched morphologies are an exciting new class of nanomaterials owing to their unique structures, physicochemical properties, and great potential as catalysts, sensing materials, and building blocks for nanoscale devices. Various strategies have recently been developed for the solution-…
On the basis of their unique electrical and mechanical properties, carbon nanotubes (CNTs) have attracted great attention in recent years. A diverse array of methods has been developed to modify CNTs and to assemble them into devices. On the basis of these innovations, many applications that include the use of CNTs ha…
CeO(2)/TiO(2) and CeO(2)-WO(3)/TiO(2) catalysts prepared by impregnation method assisted with ultrasonic energy were investigated on the selective catalytic reduction (SCR) of NO(x) (NO and NO(2)) by NH(3). The catalytic activity of 10% CeO(2)/TiO(2) (CeTi) was greatly enhanced by the addition of 6% WO(3) in the broad…
This volume of the "Journal of Biomimetics, Biomaterials and Biomedical Engineering" covers topical issue of biomimetic approach to the development of modern means of a wide range of industrial applications, the new solutions in the field of biomedical engineering and of pharmacological practice and also illuminates t…

\n\t\t\t\t\tColoured conducting textiles have shown a wide range of potential applications in heating fabrics, electromagnetic wave absorption, and wearable optoelectronic devices. This research aimed at clarifying some issues occurred in the research project on coloured conductive textiles. The investigation firstly…
Flugzeugtriebwerke und insbesondere deren Schaufeln erfahren im Einsatz einen mechanischen, thermischen und chemischen Angriff, der sich negativ auf die Lebensdauer der Bauteile auswirkt. Zur Erhöhung der Lebensdauer der Triebwerksschaufeln werden diese mit Schutzschichten versehen. \nDas Hohlkathoden-Gasfluss-Sputter…
External environment plays a major role in affecting the performance of concrete structures. Pozzolanic materials, such as fly ash, up to 50% replacement of cement, provide excellent durability properties. This paper presents the study of durability characteristics of Indian fly ash mixes with locally available ingred…

A discrete set $A$ in the Euclidian space is almost periodic if the measure with the unite masses at points of the set is almost periodic in the weak sense. We investigate properties of such sets in the case when $A-A$ is discrete. In particular, if $A$ is a Bohr almost periodic set, we prove that $A$ is a union of a…
The influence of fast neutron irradiation on the structure and spatial distribution of Ge nanocrystals (NC) embedded in an amorphous SiO2 matrix has been studied. The investigation was conducted by means of laser Raman Scattering (RS), High Resolution Transmission Electron Microscopy (HR-TEM) and X-ray photoelectron s…
