This article presents a review of current research activities on the hybrid heterostructures of inorganic nanostructures grown directly on graphene layers, which can be categorized primarily as zero-dimensional nanoparticles; one-dimensional nanorods, nanowires, and nanotubes; and two-dimensional nanowalls. For the hy…
In this communication, we demonstrate for the first time that conducting polymer polyaniline (PANI) nanofibres can serve as a novel fluorescent sensing platform for nucleic acid detection with a high selectivity down to single-base mismatch.
We report a simple and efficient method to fabricate flexible multifunctional free-standing montmorillonite-graphene (MMT-G) hybrid films viavacuum filtration. Aqueous colloidal dispersion of reduced graphene oxide (r-GO), stabilized by MMT nanoplatelets with variable content of r-GO, has been obtained by direct reduc…
A simple and effective method for the fabrication of porous nanofibers based on the solvent evaporation methods in one-step electrospinning process from the commercial polyvinyl butyral (PVB) is presented. The obtained nanofibers are prevalently amorphous with diameters ranging from 150 to 4350 nm and specific surface…
A facile approach was established for fabricating photothermo-responsive nanogels for simultaneous optical temperature-sensing, cell imaging, and combined chemo-photothermal treatment. The strategy for preparing the hybrid Au@IPN-pNIPAAm nanogels involved two steps, consisting of growing an acrylamide monolayer on a s…
Abstract In recent years extended focus has been placed on monitoring and understanding degradation mechanisms in both solid oxide fuel cells and solid oxide electrolysis cells. The time-consuming nature of degradation experiments and the disparate conclusions from experiment reproductions indicates that not all degra…
Throughout the past few decades, the development of new π-conjugated organic compounds has received a lot of attention due to their potential applications ranging from liquid crystals, light-emitting and nonlinear optical applications to self-assembly and supramolecular chemistry. Most of these applications rely on el…
A series of near-infrared (NIR) electrochromic aromatic polyamides with tetraphenylbenzidine (TPB) units were prepared by phosphorylation polyamidation from a newly synthesized aromatic diamine monomer, N,N′-bis(4-aminophenyl)-N,N′-di(4-methoxyphenyl)-4,4′-biphenyldiamine, and various dicarboxylic acids. These polymer…
A novel polymorph of boron nitride (BN) with a body-centered tetragonal structure (bct-BN) has been predicted using first-principles calculations. The structural, vibrational, and mechanical calculations indicated that bct-BN is mechanically stable at zero pressure. When pressure is above 6 GPa, bct-BN becomes energet…
Extremely hydrophobic surfaces, on which water droplets sit in a spherical shape leaving air entrapped into the roughness of the solid, are often called superhydrophobic. Hierarchically rough superhydrophobic surfaces that possess submicron scale fine structures combined with micron scale structures are generally more…
Polypyrrole(PPy)/titania(TiO 2 ) nanocomposites were prepared by an in situ oxidative polymerization method with two different oxidants, namely ammonium persulfate (APS) and ferric chloride. The effects of oxidant type and TiO 2 particle loading level on the physiochemical properties of the PPy/TiO 2 nanocomposites we…
Ordered Al nanohole arrays for tunable UV-SERS are theoretically proposed and simulated by using FDTD method. The properly designed Al nanohole arrays produce stable and predictable Raman enhancement under the deep UV laser illumination. The SERS enhancement factor as high as 5 to 6 orders of magnitude is attained in…
We addressed a novel high-strain shape memory polymer network constructed from SiO2 microspheres core functionalized with polycaprolactone arms. Using abundant surface hydroxyl of silica, epsilon-caprolactone was initiated and uniform SiO2@PCL macroparticles were formed; after cross-linking of SiO2@PCL by MDI, a high-…
Many applications of molecule based magnets, whether they are in information storage, displays, or as components in electronic or spintronic devices, will require putting the active materials on a surface or interfacing them with other components. Although there are many examples of molecule-based magnets, the familie…
We describe a unique approach to combining two kinds of radiodense elements, gold and iodine, within one single dendrimer-based nanodevice with an enhanced X-ray attenuation property for potential computed tomography (CT) imaging applications. In this approach, amine-terminated generation 5 poly(amidoamine) dendrimers…
We designed a novel oral colon-specific drug delivery system (OCDDS) using a modification of mesoporous silica nanoparticle (MSN) surfaces with pH-sensitive trimethylammonium (TA) groups through a pH-sensitive hydrazone bond. The pH-sensitive TA groups can efficiently increase the loading amounts of anionic drugs by a…
Cathodes prepared by infiltration of La0.6Sr0.4CoO3-delta (LSC40) into a porous Ce0.9Gd0.1O1.95 (CGO10) backbone have been developed for low temperature solid oxide fuel cells. The CGO10 backbone has been prepared by screen printing a CGO10 ink on both sides of a 180 mu m dense CGO10 electrolyte-tape followed by firin…
The syntheses, structural determinations and magnetic studies of tetranuclear Co(II)-Ln(III) complexes (Ln = Y, Gd, Tb) involving orthovanillin as main ligand are described. The structural studies demonstrate that centrosymmetric tetranuclear Co(2)-Ln(2) complex molecules with a defect-dicubane central core are obtain…
The thermodynamics and kinetics of hydrogen (H2) release from ethane 1,2-di-amineborane (EDAB, BH3NH2CH2CH2NH2BH3) were measured using Calvet and differential scanning calorimetry (DSC), pressure-composition isotherms, and volumetric gas-burette experiments. The results presented here indicate that EDAB releases ∼ 10…
We present a simple two-state model to understand the size-dependent endocytosis of nanoparticles. Using this model, we elucidate the relevant energy terms required to understand the size-dependent uptake mechanism and verify it by correctly predicting the behavior at large and small particle sizes. In the absence of…
