We study the long-range spatial correlations in the nonequilibrium steady state of a randomly driven granular fluid with the emphasis on obtaining the explicit form of the static structure factors. The presence of immobile particles immersed in such a fluidized bed of fine particles leads to the confinement of the flu…
Abstract To examine the versatility of the trans-bisglycoconjugation architecture for 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin (TFPP) derivative-based photodynamic therapy (PDT), 25 porphyrin derivatives bearing d-glucopyranose moieties were prepared, and their in vitro photocytotoxicities were examined. trans-…
The role of the strain state in epitaxial (001)-oriented Cu/Ni(14 nm)/Cu rings is investigated using a combination of magnetic force microscopy and finite-element calculations. Rings with an external diameter of 3 and 2 $\ensuremath{\mu}$m and linewidth $W$ larger than 400 nm show two different structures: domains wit…
The Ras converting enzyme (Rce1p) is an endoprotease that is involved in the post-translational processing of the Ras GTPases and other isoprenylated proteins. Its role in Ras biosynthesis marks Rce1p as an anticancer target. By assessing the chemical accessibility of cysteine residues substituted throughout the Sacch…
This work reports on a surprising and abnormal increase of the Raman intensity when the probing area is moved to the edge of a mechanically cleaved Si wafer. Our detailed surface structure study based on atomic force microscope and scanning electron microscope rules out any effect from surface morphology. Systematic s…
Abstract This paper examines the residual stress distributions at selected depths in three stiffened 350WT steel plates representing typical stiffened steel plates used in modern ship construction. Residual stresses can develop from the welding process, and the magnitude of these stresses can be high enough to cause a…
Silicon etching is an essential fabrication step in micro-/nanoelectromechanical systems. In this article, the inductive coupled plasma etching technology using monolayer polystyrene nanospheres as the template provides a feasible top-down dry etching method in silicon substrates. The size of the polystyrene nanospher…
Plasmonic resonances in metallic subwavelength structures have been widely exploited for a broad range of applications including nanoantennas, surface-enhanced Raman spectroscopy, chiral metamaterials, metamagnetism and absorbers. The phenomenon of extraordinary optical transmission (EOT) through subwavelength holes o…
Abstract Intergranular corrosion and intergranular stress corrosion cracking is influenced by precipitation of chromium carbides at grain boundaries and formation of chromium depletion regions. The present study focuses on understanding the carbide precipitation and subsequent sensitization in the weldments of Alloy 6…
A Proton Transfer Reaction Mass Spectrometer (PTR-MS) was used for the analysis of syngas in an industrial Fischer-Tropsch process. A PTR-MS can detect a variety of volatile organic and inorganic compounds in real-time and with high sensitivity. Together with a multiplexer, this allows for online (real-time) monitorin…
This paper describes the in situ bioconversion of glycyrrhizin of Glycyrrhiza glabra root to 18-β glycyrrhetinic acid by solid state fermentation. Fermentation was carried out with two different fungal strains, Penicillium chrysogenum and Rhizopus oryzae. The solid state fermentation was carried out under stationary s…
Abstract Abstract. Two new coordination polymers {[Cd2(BDC)2(3‐bpmp)(H2O)2]·2H2O}n (1) and [Cd2(BDC)2(4‐bpmp)]n (2) [H2BDC = 5‐hydroxy‐isophthalic acid, 3‐bpmp = 1,4‐bis(3‐pyridylmethy)piperazine, and 4‐bpmp = 1,4‐bis(4‐pyridylmethy) piperazine] were synthesized via hydrothermal synthesis, and further characterized by…
Thin films of cadmium oxide (CdO) were synthesized and characterized using chemical bath deposition (CBD) technique. The XRD studies revealed amorphous CdO thin films which upon annealing at 623K transformed to polycrystalline structure. The optical studies showed that the CdO films have high average transmittance ove…

Emergent technologies of regenerative medicine have shown immense potential to overcome the limitations of organ transplanta…
Abstract Three metal coordination polymers [Zn(bdc)(L)(H2O)]n (1), [Co(pta)(L)(H2O)2]n (2), and [Cd(tda)(L)(H2O)]n (3) [H2bdc = 1,2‐benzene dicarboxylate acid, H2pta = terephthalic acid, H2tda = 2,5‐thiophenedicarboxylic acid, L = 3,5‐bis(imidazole‐1‐yl)pyridine] were synthesized and structurally characterized by IR s…
Abstract Cosensitization of nanocrystalline TiO2 film with the cyclometalated ruthenium complex (FT89) and organic dyes (MK-45 and MK-111) improves the light-harvesting efficiency of dye-sensitized solar cells. The anchor group of the organic dyes has a large influence on the effective cosensitization. MK-45 and MK-11…
Abstract The modeling approach called “numerical fractionation” has been incorporated into a PREDICI model to simulate crosslinking copolymerization. In order to take inhomogeneities of the considered copolymerization into account, the kinetic parameters of the model are proposed to be different for each generation of…

Amorphous titanium dioxide TiO2 thin films have been deposited using the dc sputtering technique. The structure of the films was analyzed by X-ray diffraction and the results showed non-crystalline behavior. The optical properties of these thin films have been investigated by means of optical reflectance and transmitt…
Hybrid composites based on poly(ether‐ether‐ketone) (PEEK) were fabricated with fly ash and mica. Nearly 5, 10, and 15 wt% of fly ash were replaced by mica of the optimized fly ash reinforced composites and were subjected to dynamical mechanical analysis to determine the dynamic properties as a function of temperature…
