Hydrothermal reactions of Pb(NO3)2 and 3-fluorophthalic acid (H2Fpht) in the absence or presence of 2,2′-bipyridine (bpy) gave two coordination polymers: Pb5(Fpht)4(Fba)2 (1) and [Pb2(Fpht)2(bpy)(H2O)]·3H2O (2). The 3-fluorobenzoic acid (HFba) results from an in situ decarboxylation of H2Fpht. Solid 1 displays a 2-D s…
We have studied the electrochemical, optical, and magnetic properties of nickel-intercalated InSe single crystals. The energy position of the excitonic maximum and the full width at half maximum of the excitonic band in the Ni x InSe intercalation compounds have been shown to be nonmonotonic functions of nickel concen…
An aging resistant styrene-butadiene rubber (SBR) composite was prepared by using N-isopropyl-N'-phenyl-p-phenylenediamine (antioxidant 4010NA) loaded halloysite nanotube (HNT) as filler. The antioxidant loaded in the tube lumens of HNTs allowed for sustained released through HNT openings, provided longer supply of an…
The electronic structure and quantum-transport properties of Fe/Fe 2 VAl/Fe trilayers were investigated by using first-principles calculations. The high-transmission area in k-space can be confined by using a semimetallic Fe 2 VAl layer. The confined k-space originates from the small Fermi surface of Fe 2 VAl. Moreove…
Plasma polymerized allylamine films were deposited onto quartz particles for the removal of humic acid, a common water contaminant. Allylamine flow rates of 6.6 and 11.5 standard cubic centrimetres per minute (sccm) were used and the mass of particles varied from 50 to 500 g. At an allylamine flow rate of 6.6 sccm, th…
Phase diagram of alumina sol has been investigated, wherein a unique region of shear reversible gels has been discovered. In this region, rapid transformation from gel to sol was observed, where the viscosity shows a sudden drop by six orders of magnitude on application of shear stress. The sol to gel transformation w…
In this paper, we investigate the novel behavior of induced focusing in nonlinear metamaterials (MMs) through designing probe-pump configuration, where the coupled waves may simultaneously experience negative refractive index or positive refractive index, or one experiences positive refractive index and another experi…

A hybrid structure consisting of a square lattice of gold disk arrays and an overlaying gold film is proposed as an optical coupler for a backside-illuminated quantum well infrared photodetector (QWIP). Finite difference time-domain method is used to numerically simulate the reflection spectra and the field distributi…
TeO2 based glasses with the molar composition (70-x-y)TeO2-20WO3-10Y2O3-xEr2O3-yYb2O3, where x = 0 and 0.5 mol% and y = 0, 0.5, 1, 2 and 4 mol%, were prepared by the melt quenching technique. The Raman spectra of the vitreous samples, using laser excitation line of 532 nm showed a band distribution related with Te-O a…
I discuss here the contribution from J. S. Miller and co-workers concerning the discovery of ferromagnetism in an organometallic compound. The important peculiarities around this discovery, that the moments from p-electrons participate in magnetic ordering, strongly contributed to open the area of molecule-based magne…
We construct a reliable actively Q-switched Nd:YVO4laser to comparatively investigate the output performance of the second harmonic generation between the extracavity and intracavity configurations under a similar operated condition. It is experimentally found that the peak power at 532 nm obtained with the extracavit…
The photophysical properties of Ruthenium-bipyridine complexes bearing a bibenzimidazole ligand were investigated. The nitrogens on the bibenzimidazole-ligand were protected, by adding either a phenylene group or a 1,2-ethandiyl group, to remove the photophysical dependence of the complex on the protonation state of t…
It's alive! A significant step forward in the controlled radical polymerization of ethylene through the reversible addition–fragmentation chain-transfer process was reported recently by Monteil and co-workers. Control over molecular weight, dispersity of the molecular weight distribution, and polymer end groups were i…
The decoration of silicane using 16 different metal adatoms and the adsorption of small molecules are studied using first-principles calculations. Of the 16 metal adatoms, Li, Na, K, Ca, In, and Sc show a larger binding energy with silicane than their corresponding cohesive energy in the bulk, which suggests they can…
The X-ray diffraction (XRD) analysis of cement process materials has grown beyond its roots in the laboratory to become an important tool for process control. Combined with its partners, i.e., X-ray fluorescence (XRF) and controlled neutron analysis (CNA), these techniques can provide valuable process control informat…
This study demonstrated a metal-coated GaN laser from a defect cavity with shallow grating structure. With a structure optimization for surface plasmon waves, the shallow grating can support a high quality factor (Q) resonant mode, which leads to a lasing action in the metal-coated GaN cavity. The defect lasing mode w…
Vapor–liquid equilibria (boiling points) data for the ZnSO 4 –H 2 SO 4 –H 2 O and the MgSO 4 –H 2 SO 4 –H 2 O systems were determined by the quasi-static ebulliometric method at (30, 60, 90, and 101.3) kPa. The boiling points of the ZnSO 4 –H 2 O and the ZnSO 4 –H 2 SO 4 –H 2 O systems were used to regress new chemica…
The optical response of porous silicon (pSi) films, covered with a quasi-hexagonal array of hydrogel microspheres, to immersion in ethanol/water mixtures was investigated. For this study, pSi monolayers were fabricated by electrochemical etching, stabilized by thermal oxidation, and decorated with hydrogel microsphere…
We report a study of the magnetic domain structure of nanocrystalline thin films of nickel-zinc ferrite. The ferrite films were synthesized using aqueous spin-spray coating at low temperature (∼90 °C) and showed high complex permeability in the GHz range. Electron microscopy and microanalysis revealed that the films c…
