Glycopolymers offer many opportunities for interfacing synthetic materials with biological systems. However, the nature of the interactions between glycopolymers and their biological targets, lectins, and the structural features necessary to obtain high-affinity materials are not fully understood. Here, the enhancemen…
In recent times Platinum (Pt), Iridium (Ir), Iridium oxide (IrO) and Platinum-Iridium (Pt-Ir) are the favorable microelectrode materials. They show excellent electrical and mechanical properties suitable for neural stimulation and sensing/recording purposes. But their long term stability and performance is still in qu…
[Zr(OPr(i))(4)·Pr(i)OH] reacts with [HOSi(O(t)Bu)(3)] in anhydrous benzene in 1:1 and 1:2 molar ratios to afford alkoxy zirconosiloxane precursors of the types [Zr(OPr(i))(3){OSi(O(t)Bu)(3)}] (A) and [Zr(OPr(i))(2){OSi(O(t)Bu)(3)}(2)] (B), respectively. Further reactions of A or B with glycols in 1:1 molar ratio affor…
Plasmonic materials fabricated from precisely controlled metal nanostructures provide promising platforms for developing high-sensitivity sensing devices, such as pH sensors, organic vapor sensors, and other chemical sensors. Over the past several decades, a number of unconventional methods for preparing localized sur…
A survey of crystal structures containing hydantoin, dihydrouracil and uracil derivatives in the Cambridge Structural Database revealed four main types of hydrogen bond motifs when derivatives with extra substituents able to interfere with the main motif are excluded. All these molecules contain two hydrogen bond dono…
The reactions of CoX(2) (X = Cl(-), Br(-), I(-) and ClO(4)(-)) with the tripodal polypyridine N(4)O(2)-type ligand bearing pivalamide groups, bis(6-(pivalamide-2-pyridyl)methyl)(2-pyridylmethyl)amine ligand (H(2)BPPA), afforded two types of Co(II) complexes as follows. One type is purple-coloured Co(II) complexes, [Co…
High performance metal–semiconductor field-effect transistors (MESFETs) based on single n-CdSe nanobelts (NBs) have been fabricated and applied as photodetectors. Au is used as the gate metal, which formed a good Schottky contact with the CdSe NB with a rectification ratio of about 2 × 108. The CdSe NB MESFETs exhibit…
Bath stability monitoring of electroless copper deposition has been done with different methods. A combination of UV-VIS spectra and pH measurement enabled us to determine the degradation of an electroless Cu solution. The pH of the Cu-containing solution gradually decreased as a function of time, while the UV-VIS abs…
A number of porous salts based on the pamoate anion in combination with lutidinium or picolinium cations have been characterised. One salt undergoes single-crystal to single-crystal solvent exchange, while another isostructural series of salts contain channels that can be partly evacuated without collapse of the frame…
The metal-rich compounds R4PdMg (R = Ca, Eu, Tb-Lu), R4AgMg (R = Ca, Yb), R4PtMg (R = Eu, Tb-Lu), and R4AuMg (R = Ca, Eu, Yb) were synthesized by induction melting of the elements in sealed tantalum tubes in a water-cooled sample chamber. All samples were characterized by powder X-ray diffraction. The structures of Ca…
The paper presents the new C-type high harmonic power filter design process whose aim is the reduction of total harmonic distortion in an industrial power supply system. A new method for C-type filter design is proposed and an example of the method application to an industrial plant is provided. The basis for the new…
Emitting layers were thermally annealed at 20 to 100 °C for varying durations without causing phase transformation in the rest of the PhOLEDs. Heating EMLs above their Tgs with a free surface created pinholes filled by the underlying TAPC melt with concurrent interlayer mixing to emit satellite peaks accompanying FIrp…
The behavior of two ionic liquids (ILs), 1-ethyl-3-methylimidazolium dicyanamide [Emim][DCA] and 1-ethyl-3-methylimidazolium triflate [Emim][TfO], in (meso)porous carbonaceous hosts was investigated. Prior to IL incorporation into the host, the carbon matrix was thermally annealed between 180 and 900 °C to control car…
In this study, effects of the variation in the dielectric barrier discharge's (DBD) gap distance and the nature of dielectric layers which cover both of the reactor electrodes on the electron density, mass fraction of excited argon atoms across the discharge gap, mean electron energy, ion and electron current density,…
In order to solve the defects that the end-effect of magnetic field is ignored in two dimension (2-D) analytical method or 2-D finite element method (FEM); meanwhile, mass computer resource and time for parametric design or optimization are wasted in three dimension (3-D) FEM, a concise and efficient 3-D analytical ap…
TiO2 nanoporous microspheres of 20 μm diameter with good crystallinity have been obtained by precipitation from aqua solution of ammonium titanate with nitric acid at pH = 1 and T = 100oC. Pure rutile, space group P42/mnm, phase composition has been confirmed by XRD analysis of the precipitate. SEM observation of thes…
Novel pH-activatable fluorescent probes with various pK(a) values have been developed utilizing 4-nitro-benzo[1,2,5]oxadiazole derivatives (NBD) as fluorophores and piperazine moieties as proton receptors. Under acidic conditions, probe FoPz displayed significant fluorescent enhancement of about 30 fold with a pK(a) v…
BACKGROUND: Guided tissue regeneration (GTR) allows mesenchymal cells to repopulate the defects. However, there is limited information regarding the efficacy of different membranes. The present study was designed to histologically and histomorphometrically compare three collagen membranes in regenerative treatment of…
Modern instruments for small-molecule crystallography continue to become more sophisticated and more automated. This technical progress provides a basis for frontier research in chemical and pharmaceutical crystallography, but it also encourages analytical crystallographers to become more complacent and more reliant o…
An organic dual-wavelength distributed feedback (DFB) laser empowered by a dye-doped holographic polymer dispersed liquid crystal (HPDLC) grating is reported for the first time. The dual-wavelength laser operates at 586.6 nm and 670.2 nm simultaneously in one laser beam via the seventh and eighth Bragg orders of a one…
