In this study, gold-loaded titanium dioxide was prepared by an impregnation method to investigate the effect of surface plasmon resonance (SPR) on photoactivity. The deposited gold nanoparticles (NPs) absorb visible light because of SPR. The effects of both the gold content and the TiO2 size of Au/TiO2 on SPR and the…
We predicted here gravimetric hydrogen storage capacity of Ti2–C2H4 and Ti2–C2H4+ complexes using density functional theory (DFT) method. The number of adsorbed H2 on Ti2–C2H4 is limited to ten. It has been seen that controlling the charge-state of this complex enhances its gravimetric hydrogen uptake and the metal bo…
This paper reports the first systematic investigation of the selectivity of organic guest intercalation into hydroxy double salts. The organic guests 1,2- and 1,4-benzenedicarboxylate (1,2- and 1,4-BDC) have been incorporated into a range of hydroxy double salts by anion exchange. Intercalates of [Zn5(OH)8](NO3)2·yH2O…
Abstract Liquid crystal cell (LCC) for space-borne laser rangefinder to space mission applications was developed, manufactured and tested under cooperation between Military University of Technology (MUT) in Poland and Vavilov State Optical Institute (Vavilov SOI) in Russia. LCC operates in twisted nematic mode, commut…
Stretchable and highly conductive films made of poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) were prepared by casting the PEDOT/PSS aqueous dispersion as colloidal gel particles containing xylitol and subsequent heating. The electrical conductivity and elongation at break of the PED…
Nanowire-structured MnO 2 was synthesized by a sonochemical method and its electrochemical capacitances were investigated in three kinds of electrolytes: liquid-type KCl solution, potassium polyacrylate (PAAK), and potassium polyacrylate- co -polyacrylamide (PAAK-PAAM) gel polymer electrolytes (GPEs). The prepared MnO…
Heterobimetallic [Zn(II)Ln(III)] complexes have been obtained using a compartmental Schiff-base ligand, H(2)valdmpn, resulting from the 2:1 condensation between o-vanillin and 2,2-dimethyl-propilenediamine: [Zn(H(2)O)(valdmpn)Sm(O(2)NO)(3)] 1, [Zn(H(2)O)(valdmpn)Tb(O(2)NO)(3)] 2a, [Zn(H(2)O)(valdmpn)Tb(O(2)NO)(3)]·H(2…
A cotton-assisted preparation method of mesoporous manganese oxides for supercapacitors is reported. The samples were fully characterized to study the morphology, chemical composition, surface area and pore structure. The results of the electrochemical tests show that these electrode materials possessed good capacitiv…
Previous fiber-shaped solar cells are based on polymeric materials or dye-sensitized wide band-gap oxides. Here, we show that efficient fiber solar cells can be made from semiconducting nanostructures (e.g. CdSe) with smaller band-gap as the light absorption material. We directly grow a vertical array of CdSe nanowire…
The electronic properties of carbon nanotubes can be altered significantly by modifying the nanotube surface. In this study, single-walled carbon nanotubes (SWCNTs) were functionalized noncovalently using designed surfactant peptides, and the resultant SWCNT electronic properties were investigated. These peptides have…
The effect of coadsorption on the conformational arrangement of human plasma fibronectin (Fn) was studied for mixtures with human serum albumin (HSA) adsorbed onto mildly hydrophilic gold substrates. Quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM) were used to measure…
The CdS/ZnS core/shell quantum dots (QDs) are synthesized in a water-in-oil (w/o) microemulsion system (reverse micellar method). The thickness of the shell is controlled by the molar ratio of water-to-surfactant (R), and the final particle size increases with the increasing of R ratio. The optical properties of CdS/Z…
The synthesis of a novel electropolymerizable monomer, 2,2′,3,3′-tetrahydro-2,2′-bithieno[3,4-b][1,4]dioxine (THBTD), based on two 3,4-ethylenedioxythiophene (EDOT) moieties connected through the ethylenedioxy bridge is reported. The new monomer paves the way for the development of cross-linked networks based on the E…
Gadolinia doped ceria in its doped or strained form is considered to be an electrolyte for solid oxide fuel cell applications. The simulation of the defect processes in these materials is complicated by the random distribution of the constituent atoms. We propose the use of the special quasirandom structure (SQS) appr…
Polyhedral silsesquioxanes are considered valuable conjugation scaffolds. Nevertheless, only a few examples of silsesquioxane-assembled peptide oligomers have been reported to date. We developed a new bioorthogonal cube-octameric silsesquioxane (COSS) scaffold bearing eight aminooxy coupling sites allowing for the con…
A class of shape-persistent metallodendrimer has been developed through a self-assembly strategy, in which 〈tpy-RuII-tpy〉 or 〈tpy-FeII-tpy〉 connectivity is utilized, as branching moieties or nodes. These metallomacromolecules were fully characterized by 1H and 13C NMR, traveling wave ion mobility mass spectrometry (TW…
The design of new amphoteric catalysts is of great interest for several industrial processes, especially those covering dehydration and dehydrogenation phenomena. Adsorption microcalorimetry was used to monitor the design of mixed oxides of zinc with Group 3 elements (aluminium, gallium, indium) with amphoteric charac…
We studied computationally the leaching of palladium from the ideal surface Pd(111) and its various structural defects at different coverages of CO, using density functional calculations on slab models. Accordingly, the energy required for leaching of a single Pd atom from a bare surface is quite large, at least ∼270…
The aim of this work is to study the physical properties of Cr2O3 -doped soda lime silicate glass in batch of 25Na2O: 10CaO: (65-x)SiO2: xCr2O3 where 0.00 ≤ x ≤ 0.05 mol%. The glass samples were prepared by normal meltquenching technique with 1500 °C melting-temperature. The amorphous structure of glass samples were c…
