Aluminium (Al) and iron (Fe) play a key role in pedogenetic processes; however, short‐term changes in Al‐ and Fe‐bearing secondary minerals are little documented. In this study, Al and Fe dynamics in the solid phase have been evaluated in three soil compartments (bulk, ‘rhizosphere outer’, corresponding to soil volume…
Abstract Thin films of Fe-containing the Aurivillius phase Bi 5 FeTi 3 O 15 (BFTO) were successfully prepared by chemical solution deposition. The microstructure, ferroelectric behaviours, magnetic properties and the magneto-dielectric effect were investigated systematically at room temperature (RT). A definite hyster…
The rhombohedral elementary cell of the complex boron carbide structure is composed of B(12) or B(11)C icosahedra and CBC, CBB or B□B (□, vacancy) linear arrangements, whose shares vary depending on the actual chemical compound. The evaluation of the IR phonon spectra of isotopically pure boron carbide yields the quan…
The electronic spin associated with the nitrogen vacancy (NV) color center in diamond is an excellent candidate for a solid-state qubit functioning as a quantum register or sensor. However, the lack of thin film technologies for crystalline diamond with low impurity levels hampers the development of photonic interface…
Despite the promising applications of copper selenide nanoparticles, an in-depth elucidation of the inherent properties of tetragonal Cu(2)Se (β-Cu(2)Se) has not been performed because of the lack of a facile synthesis on the nanoscale and an energy-intensive strategy is usually employed. In this work, a facile wet-ch…
An injectable nanofibrous hydrogel scaffold integrated with growth factors (GFs) loaded polysaccharide nanoparticles was developed that specifically allows for targeted adipose-derived stem cells (ASCs) encapsulation and soft tissue engineering. The nanofibrous hydrogel was produced via biological conjugation of bioti…
Equal channel angular pressing is one of the techniques in metal forming processes in which an ultra-large plastic strain is imposed on a bulk material in order to make ultra-fine grained and nanocrystalline metals and alloys. The technique is a viable forming procedure to extrude materials by use of specially designe…
Abstract Niobium(V)‐containing silica catalysts were prepared by deposition of niobocene dichloride onto the surface of high‐surface area silica supports following a dry impregnation or a liquid‐phase grafting approach. These materials were used as heterogeneous catalysts for the selective epoxidation, in the presence…
We present electrical and thermal specific heat measurements that show superconductivity in double-wall carbon nanotube (DWCNT) bundles. Clear evidence, comprising a resistance drop as a function of temperature, magnetoresistance and differential resistance signature of the supercurrent, suggest an intrinsic supercond…
Abstract The fabrication of hierarchical and bioactive self‐supporting membranes, which integrate physical and biomolecular elements, using a single‐step process that combines molecular self‐assembly with soft lithography is reported. A positively charged multidomain peptide (with or without the cell‐adhesive sequence…
By a reusable transfer fabrication technique, we demonstrate high-fidelity fabrication of metal nanoparticles, optical nanoantennas, and nanohole arrays directly on a functional silk biopolymer. The ability to reproducibly pattern silk biopolymers with arbitrarily complex plasmonic arrays is of importance for a variet…
Ballistic thermoelectric properties in graphene-nanoribbon-based heterojunctions are investigated by using the nonequilibrium Green's function approach and the Landauer transport theory. The results show that the phonon thermal conductances have similar effects for the different heterojunctions, while the electron tra…
Ultra-light Ni nanofoams composed of nanowires have been synthesized on a large scale by a facile reflux approach. From the Ni nanofoam, many other functional nanofoams, composed of semi-hollow NiO nanowires, multi-generation Ni nanowires, and noble metal nanotubes, can be easily derived for many important application…
Abstract The present work introduces a new type of biohybrid materials that is based on the combination of fibrous clays (sepiolite or palygorskite) with zein, a highly hydrophobic protein extracted from corn. C, H, N, and S chemical analyses, FTIR spectroscopy, 13 C solid‐state NMR spectroscopy, field‐emission scanni…
Abstract Atomically thin hexagonal boron nitride films were grown on both the top and bottom surfaces of a polycrystalline Co or Ni film by annealing a Co (Ni)/amorphous boron nitride/SiO 2 structure in vacuum. This method of growing hexagonal boron nitride is much simpler than other methods, such as thermal chemical…
MicroRNAs (miRNAs) are small non-coding RNAs that act as post-transcriptional gene regulators and have been shown to regulate many biological processes including embryonal development, cell differentiation, apoptosis, and proliferation. Variations in the expression of certain miRNAs have been linked to a wide range of…
Growth of Ga-doped ZnO by pulsed laser deposition at 200 °C in an ambient of Ar and H2 produces a resistivity of 1.5 × 10−4 Ω-cm, stable to 500 °C. The resistivity can be further reduced to 1.2 × 10−4 Ω-cm by annealing on Zn foil, which reduces the compensating Zn-vacancy acceptor concentration NA to 5 × 1019 cm−3, on…
A dense oxidation protective SiC – Si ceramic coating with well‐dispersion SiC nanowires was prepared on carbon/carbon ( C / C ) composites using a two‐step technique consisting of chemical vapor deposition and hot‐pressing reactive sintering. The results showed that the toughness and thermal shock resistance of the c…
Abstract Fabrication of functionalized surfaces using polymer brushes is a relatively simple process and parallels the presence of glycocalyx filaments coating the luminal surface of our vasculature. In this paper, we perform atomistic-like simulations based on dissipative particle dynamics (DPD) to study both polymer…
Graphene oxide (GO) monolayers obtained by Langmuir Blodgett route and suitably treated to obtain reduced graphene oxide (RGO) monolayers were studied by photoelectron spectroscopy. Upon reduction of GO to form RGO C1s x-ray photoelectron spectra showed increase in graphitic carbon content, while ultraviolet photoelec…
