We report the results of a theoretical study of graphene/BN/graphene and BN/graphene/BN trilayers using the van-der-Waals-corrected density functional theory in conjunction with the non-equilibrium Green's Function method. These trilayer systems formed from graphene and BN exhibit distinct stacking-dependent features…
Relative cross sections for dissociative electron attachment (DEA) and dissociative ionization (DI) of the FEBID precursor, trimethyl (methylcyclopentadienyl) platinum(iv), MeCpPtMe(3), are presented. The most pronounced DEA process is the loss of one methyl radical, while the loss of two or three methyl groups along…
A novel acrylate modified 3,4-ethylenedioxythiophene (EDOT-AA) was synthesized, and its free radical polymerization and electrochemical polymerization led to the formation of corresponding precursor polymer polyacrylate (PAA) functionalized with 3,4-ethylenedioxythiophene (EDOT-PAA) and uniform electrodeposition of ac…
Silica nanorattles (SNs) have proven to be promising vehicles for drug delivery. In order to further enhance efficacy and minimize adverse effects, active targeted delivery to tumors is necessary. In this work, SNs modified with a tumor specific targeting ligand, folic acid (FA), was used as carrier of doxorubicin (DO…
We fabricate a bioinspired spindle-knotted fiber (BSF) via an improved method of Rayleigh instability break-up droplets. The BSF is composed of multi-level spindle-knots that can generate continuous gradients of surface energy and different Laplace pressures. We investigate the water collecting ability of BSF under hu…
It is essential to tailor the electronic properties of graphene in order to apply graphene films for use in electrodes. Here we report the modification of the electronic properties of single layer chemical vapor deposition (CVD) grown graphene by molecular doping without degrading its transparency and electrical prope…
Highly biocompatible multifunctional nanocomposites consisting of monodisperse manganese oxide nanoparticles with luminescent silica shells were synthesized by a combination of w/o-microemulsion techniques and common sol–gel procedures. The nanoparticles were characterized by TEM analysis, powder XRD, SQUID magnetomet…
Abstract—The lack of wave-plates for the terahertz region opens the way for novel components/devices enabling polarization control at these frequencies. With the aid of chiral metamaterials — a new class of metamaterials — novel possibilities for the fabrication of multilayer structures for the realization of polariza…
Carboxylic acid functionalized thermally hydrocarbonized porous silicon nanoparticles (UnTHCPSi‐NP) were synthesized, and their opsonization and targeting properties were studiedin vitroalongside within vivobiodistribution. The carboxyl groups on UnTHCPSi were utilized to further functionalize the nanoparticles. In or…
Aligned Ni-NiO core-shell nanowire arrays on a glass substrate were prepared via electrochemical deposition using porous alumina oxide templates. The core-shell nanowire electrodes displayed prominent supercapacitive behaviors. The rate capability of the electrodes depends strongly on the thickness of the NiO shell la…
We describe a facile and flexible approach for synthesizing uniform non-spherical micron sized PMMA (poly(methyl methacrylate)) colloids with well-controlled protrusions. When homogeneously cross-linked PMMA spheres were used as seeds in a swelling process using again a methyl methacrylate monomer, they were found to…
2LiBH4–MgH2 is an attractive system for hydrogen storage. However, its dehydriding and rehydriding kinetics have to be further improved for practical applications. To solve these problems, three transition metal chlorides (FeCl2, CoCl2 and NiCl2) were introduced into the 2LiBH4–MgH2 system and their catalytic roles in…
Gold nanoparticles functionalized with Gd(3+) chelates displaying fast water exchange, superb pH stability and inertness towards transmetalation with Zn(2+) have been prepared and characterized as a new high relaxivity (29 mM(-1) s(-1), 30 MHz, 25 °C) contrast agent potentially safe for in vivo MRI applications. The L…
High performance nickel cobaltite (NiCo 2 O 4 ) with ultrahigh capacitance is synthesized by a facile sol-gel process and then calcined at 300 • C. The structure and morphology is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), and nitrogen adsorpti…
Graphene nanosheets have been generated in the confined space of the two-dimensional galleries of a layered double hydroxide (LDH) and good control over the number of graphene layers can be achieved by adjusting the amounts of intercalated carbon source.
An easy and cost effective route for mass production of graphene nanosheets (GNSs) is an essential requirement for design of different sensors, conductive composites and future nanoelectronic devices. Scalable and large area GNSs were synthesized by a thermal treatment of a graphite–ionic liquid crystal composite as a…
Ferroelectric and antiferroelectric materials, with complex perovskite structures, have experienced wide interest due to their peculiar structure and properties. In this highlight, recent advances of these two types of materials are reviewed, with particular emphasis on piezoelectrics/ferroelectric and antiferroelectr…
A series of water-soluble YVO4:Bi3+,Eu3+ nanocrystals, with surfaces functionalized by a branch polyethylenimine (BPEI) polymer, have been synthesized via a one-pot hydrothermal method. It was found that the particle size and crystal morphology could be efficiently controlled by different reaction temperatures, pH val…
The development of advanced support materials displays the potential for both reducing the cost and simultaneously increasing the activity of catalysts.

The bottom-up fabrication of facile, lower-cost, larger areas optical metamaterials (OMMs) is expected to provide important benefits for applications in stealth technology and communication networks. Currently available OMMs at optical wavelengths are all composed of periodic structures, and fabricated by top-down app…
