Atomic-resolution image of a graphene sheet synthesized by remote plasma-enhanced atomic layer deposition at low temperatures.
Article Energy consumption of the nanofibrillation of bleached pulp, wheat straw and recycled newspaper through a grinding process was published on January 1, 2014 in the journal Nordic Pulp & Paper Research Journal (volume 29, issue 1).
By developing a new method for synthesizing atomically monodisperse Au15 nanoclusters stabilized with glutathione molecules and using the current state-of-the-art methods for synthesizing monodisperse protected Au25 nanoclusters, we investigated their nonlinear optical (NLO) properties after two-photon absorption. The…
Random packings of objects of a particular shape are ubiquitous in science and engineering. However, such jammed matter states have eluded any systematic theoretical treatment due to the strong positional and orientational correlations involved. In recent years progress on a fundamental description of jammed matter co…
Recent research activities on the surface modification and biomedical applications of TiO <sub>2</sub> NTAs are reviewed.
Polyurethane microcapsules containing water-borne polyurethane (PU) paint as a core material for self-repairing protection coatings were successfully manufactured <italic>via</italic> interfacial polymerization of diol–diisocyanate prepolymer and 1,4-butanediol as a chain extender in an emulsion solution.
The well-known single parabolic band (SPB) model has been useful in providing insights into the understanding of transport properties of numerous thermoelectric materials. However, the conduction and valence bands of real semiconductors are rarely truly parabolic which limits the predictive power of the SPB model. The…
A liquid solar thermal fuel is developed; a low-molecular weight liquid trans-azobenzene derivative shows facile photoisomerization to the higher-energy cis-isomer in neat condition so that a high volumetric energy density is achieved. Shear viscosity measurements for each isomer liquid unveiled transitions from non-N…
Porous silicone sponges are fabricated by polymerization of organosilanes in the presence of Fe3O4@silica nanoparticles. The sponges feature fast magnetic responsivity, superhydrophobicity/superoleophilicity, high compressibility and stability. The sponges can selectively absorb floating oils on a water surface, heavy…
The development of promising microwave absorbing materials is a booming field of research in both the commercial and defense sectors to prevent electromagnetic pollution, and also to enrich the field of stealth technology. Supercapacitors are a symbol of clean energy storage devices. The present work attends to the pr…
Syntheses of metal and oxide nanocrystals with cubic crystal structures and well-controlled polyhedral morphologies such as cubic, octahedral, and rhombic dodecahedral shapes exposing, respectively, {100}, {111}, and {110} surfaces enable a more accurate determination of their facet-dependent properties. So far molecu…
Charged active sites are hypothesized to participate in heterogeneously-catalyzed reactions. For example, Auδ+ species at the catalyst surface or catalyst–support interface are thought to promote the thermally-driven CO oxidation reaction. However, the concept of charged active sites is rarely extended to electrochemi…
Highly stable colloidal silver nanoparticles with potent anticancer activity against MCF-7 cells were synthesized using <italic>Taxus baccata</italic> extracts.
A redox-active gel polymer electrolyte was prepared by introducing KI/VOSO4 redox additives into a polyvinyl alcohol–H2SO4 gel electrolyte for application in a quasi-solid-state electric double-layer capacitor (EDLC) based on activated carbon. The EDLC obtained had a high electrode-specific capacitance of 1232.8 F g−1…
The graphene-MnO2-polyaniline (rGO-MnO2-PAn) ternary composites were prepared via in situ chemical oxidative polymerization of polyaniline on the MnO2 decorated graphene sheets. The graphene sheets were treated with KMnO4 in a water-ethylene glycol system using the hydrothermal method to complete the loading of MnO2 o…
A dual stimuli-responsive system was constructed by introducing methyl viologen into a luminescent europium-organic framework with a compact packing mode. In addition to absorption and emission properties that are sensitive to both light and heat involving electron/energy transfer processes, the photoactive MOF has a…
Copper nitride (Cu <sub>3</sub> N) thin films were grown by reactive sputtering using a high-throughput combinatorial approach with orthogonal gradients of substrate temperature and target–substrate distance.
Plasmonic absorption of light can lead to significant local heating in metallic nanostructures, an effect that defines the subfield of thermoplasmonics and has been leveraged in diverse applications from biomedical technology to optoelectronics. Quantitatively characterizing the resulting local temperature increase ca…

The potential uses and benefits of nanotechnology are enormous. These include management of insect pests through the formulatio…
Silica nanoclusters were homogeneously dispersed into an end-linked PolyDiMethylSiloxane (PDMS) matrix. Dynamic relaxation, glass and melt crystallization of end-linked PDMS-silica nanocomposites (PDMSnanoSi) were compared to those of PDMS. A particular emphasis is made on the kinetic aspects of these transitions by c…
