Three compounds with the general formulae [H(2)N(Me)(2)](3)[Ln(2,6-dpa)(3)] were prepared from cheap and readily available reactants. Microcrystalline compounds could be isolated in high yields (>80%) by a simple filtration, after only one hour reaction time in refluxing DMF. The Eu and Tb compounds have been structur…
An ultrafine nanoporous Ag80Pd20 alloy can be fabricated by chemical dealloying of a rapidly solidified Mg60Ag32Pd8 alloy. The addition of the third element Pd into Mg–Ag realizes the design and functionalization of a nanoporous bimetallic structure, which exhibits superior catalytic activity towards electro-oxidation…
The paper reports on the fabrication of superhydrophobic boron-doped diamond nanograss surfaces. The boron-doped diamond nanograss array (BDD NG) was prepared simply by reactive ion etching (RIE) with oxygen plasma of highly boron-doped (the boron doping level is 8 × 1019 B cm−3) polycrystalline diamond electrodes. De…
Electrohydrodynamic co-jetting of two different nanocrystal suspensions can result in anisotropic nanocomposite particles. Using this approach, we are able to prepare submicron-sized, spherical Janus particles (464 ± 242 nm), which are not only comprised of two chemically distinct compartments, but are also morphologi…
Lithium cadmium phosphate glasses were prepared by melt quench technique. These glasses contain a mole % composition of x% Li2O-(50-x)% CdO-50%P2O5. The quantity x varies from 0-40 mole%. The physical properties reported in this paper are mass density ρ, modulus of rigidity η, coefficient of linear expansion α, transi…
Broadband spectral conversion from visible light to near-infrared radiation in Ce(3+)-Er(3+) codoped yttrium aluminium garnet is reported. Excitation, emission, time-resolved luminescence spectra and fluorescence decay curves have been measured to prove the energy transfer from Ce(3+) to Er(3+). The broadband and stro…
High-performance central processing units (CPUs) and power devices such as IGBTs have high electrical power dissipation, which causes substantial heating. As a result, efficient cooling is essential for insulating materials within such devices. Although polymers such as epoxy resins are good insulating materials, they…
The functionalization of self-assembling peptide scaffolds with biologically active motifs presents many possibilities for the design of synthetic biological materials for 3D cell culture, reparative, regenerative medicine and tissue engineering. We here report the development of short self-assembling peptide scaffold…
A new low symmetry octanuclear cyano-based {Fe(III)(4)Ni(II)(4)} single-molecule magnet (SMM) is described. This SMM exhibits the highest energy barrier (Delta/k(B) approximately 33 K) for magnetization reversal seen for any first-row cyanide-based complex. The importance of anisotropy axes alignment and their impact…
Hollow CdSe nanospheres were successfully synthesized by a ligand-assisted solvothermal method based on an Ostwald ripening mechanism. The hollow CdSe nanospheres were synthesized in benzyl alcohol under solvothermal conditions using Cd(Ac)2 and Se as the precursors, and tryptophan as a ligand. The resulting hollow st…
The very low-temperature synthesis (20–80 °C) of sub-15 nm BaxSr1−xTiO3 (0 ≤ x ≤ 1) nanocrystals and characterization of their dielectric properties as a function of composition are reported. A series of BaxSr1−xTiO3 nanocrystals were synthesized under ultrabenign conditions (i.e., low temperatures, ambient pressure a…
The reduction of Specific Absorption Rate (SAR) with metamaterial is performed by the finite-difference time-domain method (FDTD) with Lossy-Drude model by CST Microwave Studio in this paper. The metamaterials can be achieved by arranging split ring resonators (SRRS) periodically. The SAR value has been observed by va…
Nearly monodisperse NaGdF(4) and GdF(3) nanowires/nanorods as well as GdBO(3) microplates/microflowers have been successfully prepared by a designed chemical conversion approach using Gd(OH)(3) nanowires/nanorods as precursors via a facile hydrothermal approach. The Gd(OH)(3) nanowires/nanorods precursors were prepare…
A detailed understanding of the mode of packing patterns that leads to the gelation of low molecular mass gelators derived from bile acid esters was carried out using solid state NMR along with complementary techniques such as powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), thermogravimetric…
We have reported here the effect of axial ligand L (L: pyridine/substituted pyridine) on Fe(III)(tn-OEP)Cl/Fe(III)(tn-OEP)ClO(4) that first form high-spin Fe(III)(tn-OEP)(L)(2).X (X: Cl, ClO(4)) which, on longer exposure, spontaneously auto reduce to a series of air stable Fe(II)(tn-OEP)(L)(2) complexes. The introduct…
We report the synthesis of a series of monodispersed Bi-doped PbTe nanocrystals with tunable morphologies by using a doping precursor of bismuth(III) 2-ethylhexanoate.

The step-by-step growth of highly oriented and continuous thin films of [Cu2(ndc)2(dabco)] (1) at 50 °C was studied and compared with growth directly from solvothermal mother solution at 120 °C. The substrates were bare unmodified SiO2, Al2O3 grown by atomic layer deposition (ALD), Ta2O5 and Si3N4. The deposited layer…
In this study, a series of 3-D interconnected porous scaffolds with various pore diameters and porosities was fabricated by freeze-drying with non-toxic biodegradable waterborne polyurethane (WBPU) emulsions of different concentration.
