Abstract The high‐pressure behavior of Ni‐filled and Fe‐filled multiwalled carbon nanotubes has been investigated up to 27 GPa and 19 GPa, respectively, with the help of synchrotron‐based angle‐dispersive X‐ray diffraction. These nanotubes do not show any structural transformation up to the highest pressures studied.…
Performance of diatomite based mercury sorbent (Chromosorb® QSR) powder and pellets was studied. Test results indicated that this sorbent was highly effective in removing various mercury species from aqueous and oil matrices. More than 99% removal was achieved after 30 min treatment with the diatomite sorbent powder a…
The presently known approaches to the synthesis of non-symmetrically substituted phthalocyanines of the A3B and A2B2 types are surveyed. The prospects for the use of these compounds for the synthesis of binuclear and heteronuclear complexes and phthalocyanine oligomers and polymers are demonstrated.
Amphiphilic diblock copolymers composed of methoxy polyethylene glycol (MePEG) and poly(D, Llactide) (PDLLA) were prepared for the preparation of polymeric micelles. The use of MePEG-PDLLA as drug carriers has been reported in the open literature, but there are only few data on the application of a series of MePEG-PDL…
The Arrhenius plots of heterogeneous solids comprising of lithium aluminum titanium phosphate (LATP) glass–ceramic, Al 2 O 3 , and Ba 0.6 Sr 0.4 TiO 3 (0.6 BST) exhibit an inflection or peak around 27°C, which is interpreted as a signature of space charge. The space charge is formed by the adsorption of lithium ions o…
Epitaxial ZnO(0001) thin films have been grown by pulsed-laser deposition on $a\text{\ensuremath{-}}{\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ and investigated by deep level transient spectroscopy (DLTS) and by Fourier transform infrared photocurrent (FTIR-PC) spectroscopy in the midinfrared wavelength range. FTIR-PC spectra…
Homogeneous polystyrene monolayers covalently end-attached on mica and silica surfaces were obtained using a "graft to" methodology. The grafting was achieved via nucleophilic substitution between silanol groups (Si-OH) containing surface and monochlorosilyl terminated polystyrene (PS). Different parameters, such as s…
A computationally efficient numerical scheme is presented for the phase-field model of two-phase systems for anisotropic interfacial energy. The scheme is solved by using a nonlinear multigrid method. When the coefficient for the anisotropic interfacial energy is sufficiently high, the interface of the system shows co…
We present a study of the adsorption of hydrogen on nanotube bundles and 4 different carbon fragment geometries as a function of their specific surface. The sorption process is investigated using grand canonical Monte Carlo methods in terms of the gravimetric and volumetric storage densities, as a function of radius,…
Powders of Nd/V‐doped Bi 4 Ti 3 O 12 with a composition Bi 3.74 Nd 0.26 Ti 2.98 V 0.02 O 12.01 (BNTV), prepared by the molten salt synthesis, using chlorides as the fluxes, were successfully obtained. The influences of the molar ratio of KCl to NaCl, temperature, and soak time on the formation and morphology of BNTV w…
This paper presents a concise review of synthetic strategies for nanoparticle-cored dendrimers from metal nanoparticles, with an emphasis on their current applications. The synthesis of nanoparticle-cored dendrimers represents an important advance to the control and preparation of new organized nanostructures. The mos…
Catalytic processes that occur under conditions of the targeted unsteady state of the catalyst are considered. The highest efficiency of catalytic processes was found to be ensured by a controlled combination of thermal non-stationarity and unsteady composition of the catalyst surface. The processes based on this prin…
Abstract A high resolution X‐ray diffraction method has been effectively used for the structural characterization of InP porous layers. It was revealed that strong diffuse scattering from pores around reciprocal lattice points does depend on the azimuth positions of samples. To extract structural information about por…
Abstract Bis‐piperidiniummethyl‐urea (BPMU) was developed as a volatile corrosion inhibitor (VCI) for mild steel. Its vapor corrosion inhibition property was evaluated by volatile inhibiting sieve test (VIS). Electrochemical measurements were conducted in simulated atmospheric corrosion water. Electrochemical impedanc…
Extensive molecular dynamics (MD) simulations were carried out to compute the solubilities and self-diffusivities of CO2 and CH4 in amorphous polyetherimide (PEI) and mixed-matrix PEI generated by inserting single-walled carbon nanotubes into the polymer. Atomistic models of PEI and its composites were generated using…
We have investigated a change in the crystal structures of di(4-alkoxybenzyl) ( E, E )- and ( Z, Z )-muconates during the solid-state polymerization by X-ray crystal structure analyses and have discussed a reaction mechanism for the polymerization. The solid-state polymerization is divided into a homogeneous polymeriz…
Abstract Here we show the possibility to obtain azopolysiloxanes modified with nucleobases (adenine and thymine) with potential application in immobilization and nanomanipulation of biomolecules. We propose a photofluidization mechanism based on the concept of the conformational instability, which can explain the pres…
Dodecylamine-intercalated vanadium oxide nanotubes were obtained by distinct synthesis processes. Water intercalation in the nanotube structure was identified in a marked manner by the distortion of the $\mathrm{V}{\mathrm{O}}_{x}$ layers in the x-ray diffraction patterns and enhanced ${\mathrm{V}}^{4+}\mathrm{O}$ ab…
Biphenyl-bridged mesoporous organosilica with molecularly ordered pore walls was successfully synthesized under acid conditions in the presence of triblock copolymer P123 as structure-directing agent and butanol as additive. This material exhibited high surface area and larger pores and pore volume than the correspond…
We have investigated the self-assembling process of cellulose artificially synthesized via enzymatic polymerization as one of general problems of chemical reactions at specific sites and reaction-induced self-assembling process of reaction products in the context of nonequilibrium phenomenon and pattern formation. The…
