Copper nanoparticles were synthesized by thermal decomposition using copper chloride, sodium oleate, and phenyl ether as solvent agents. The formation of nanoparticles was evidenced by the X‐ray diffraction and transmission electron microscopy. The peaks in the XRD pattern correspond to the standard values of the face…
Article Cellulose nanofibrils: Challenges and possibilities as a paper additive or coating material – A review was published on January 1, 2014 in the journal Nordic Pulp & Paper Research Journal (volume 29, issue 1).
Recently we have shown the self-healing ability of a poly(urea-urethane) elastomer reversibly cured with aromatic disulfide bridges. Here we show that although being chemically crosslinked, such materials can be easily reprocessed by applying heat and pressure to obtain any desired form. This offers a unique paradigm…
Confocal laser microscopic images of HeLa cells using CDs as fluorescent probes.
Poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) is a widely used conductive polymer in the field of flexible electronics.
Using density functional theory combined with Monte Carlo (MC) simulations, we show that the two dimensional (2D) MnS2 and MnSe2 sheets are ideal magnetic semiconductors with long-range magnetic ordering and high magnetic moments (3 μB per unit cell), where all the Mn atoms are ferromagnetically coupled, and the Curie…
BACKGROUND: Engineered carbon nanotubes are currently used in many consumer and industrial products such as paints, sunscreens, cosmetics, toiletries, electronic processes and industrial lubricants. Carbon nanotubes are among the more widely used nanoparticles and come in two major commercial forms, single-walled carb…
Recent progress in phase- and morphology-controlled solution combustion synthesis envisages mass fabrications of nanomaterials with more specified phases and morphologies.
On the basis of first-principles calculations, we demonstrate the potential application of silicene as a highly sensitive molecule sensor for NH3, NO, and NO2 molecules. NH3, NO and NO2 molecules chemically adsorb on silicene via strong chemical bonds. With distinct charge transfer from silicene to molecules, silicene…
Icing of surfaces is commonplace in nature, technology and everyday life, bringing with it sometimes catastrophic consequences. A rational methodology for designing materials with extraordinary resistance to ice formation and adhesion remains however elusive. We show that ultrafine roughnesses can be fabricated, so th…
In this paper, we report that NiFe2O4 nanoparticles can be directly grown on a flexible carbon cloth substrate by a facile surfactant-assisted hydrothermal method. The produced carbon cloth/NiFe2O4 (CC/NiFe2O4) electrodes with a loading density of 1.55 mg cm−2 exhibited excellent electrochemical performances in both 6…
A thin film of Ni nanocone arrays loaded with MnO 2 nanostructures is prepared by an electro-deposition process and peeled off from the carrier substrate. This electrode shows superior performance for micro-supercapacitors.
Six coal samples of different ranks have been used to prepare single-layer graphene quantum dots (S-GQDs). After chemical oxidation and a series of centrifugation separation, every coal could be treated into two fractions, namely, CoalA and CoalB. According to the characterization results of TEM, AFM, XRD, Raman and F…
The thermoelectric properties of ICPs doped with different counterions have been investigated. An experimental value of ZT = 0.22 has been obtained for PEDOT:bis(trifluoromethylsulfonyl)imide.
Contributions of morphology, surface area, and defect content, on the photocatalytic activity of ZnO nanostructures have been discussed.
Nanoceria is an exceptionally versatile, commercially valuable catalytic material whose properties vary dramatically from that of the bulk material.
Conjugated microporous polymers are developed as a new platform for lithium-battery energy storage, which features a near-unity coulombic efficiency, high capacity and cycle stability. The polymers exhibit synergistic structural effects on facilitating charge dynamics by virtue of their built-in redox skeletons, open…
Nanocomposites, consisting of a polymeric matrix and nanosized elements as reinforcement, have attracted significant scientific attention because of their high mechanical performance. A large variety of nanocomposites have been prepared using bio‐based materials as a matrix and nanoreinforcement, so that it can reduce…
CoNi 2 S 4 /graphene nanocomposite electrodes exhibit excellent pseudocapacitance behavior enhanced by synergistic effect, demonstrating the nanocomposite's promise as an electrode material for high-performance supercapacitors.
We report a novel approach for fabricating gold nanostar-functionalized substrates for highly sensitive surface enhanced Raman spectroscopy (SERS)-based chemical sensing. Gold nanostars immobilized on a gold substrate via a Raman silent organic tether serve as the SERS substrate, and facilitate the chemical sensing of…
