The phase composition and unit cell parameters were determined for composites based on polylactide and hydroxyapatite with the polylactide/hydroxyapatite weight ratios of 90/10, 80/20, 70/30, and 60/40. As the polylactide content of the composites is increased, they become less hydrophilic, and the surface energy σ S-…
Green chemistry methods for nanoparticles synthesis have implemented the valorization of renewable waste that reduces the use of chemicals and sub-products to minimize the environmental impact. Herein, we report a method to synthesize Ag and Au nanoparticles (AgNPs, AuNPs) using one of the worlds worst aquatic weeds,…
Controlling the size polydispersity of colloidal particles is important for their phase transitions, resulting structures, and properties. In this study, a fractionation method was established to control the polydispersity of colloidal plates based on the isotropic–nematic (I–N) phase transition. The size ratio of nan…
Graphene is an ideal membrane for selective separation because of its unique properties and single-layer structure. Considerable efforts have been made to alter the permeability of graphene. In this study, we investigate the pathways for an oxygen atom to pass through graphene sheets. We also identify the effect of th…
The preparation and observations of spheroplast W303 cells are described with Environmental Scanning Electron Microscope (ESEM). The spheroplasting conversion was successfully confirmed qualitatively, by the evaluation of the morphological change between the normal W303 cells and the spheroplast W303 cells, and quanti…
We previously reported that unmodified silica nanoparticles with diameters of 70 nm (nSP70) induced liver damage in mice, whereas nSP70 modified with carboxyl or amino groups did not. In addition, we have found that both unmodified and modified nSP70s localize in both Kupffer cells and parenchymal hepatocytes. We ther…
The synthesis of new corrugated layers of graphene is presented and its composite with polyaniline was electrochemically characterized for supercapacitor electrodes.
Study of the physical and electrical properties of the Sr 2 Fe 1.5 Mo 0.5 + Ce 0.8 Sm 0.2 O 1.9 composite material and its electrochemical properties as an electrode in contact with lanthanum gallate based electrolyte based on in reducing media revealed an increase in the dilatometric curve slope at around 400°C. This…
The use of hyperbranched polyesterpolyols of different generations favors firmer fixation of carbon nanotubes and silver nanoparticles as components of composite materials on the electrode surface (0.028 mg cm –2 ), which improves the operation characteristics of monoamine oxidase biosensors. The size of silver nanopa…
Hydrogen isotopes plasma-driven permeation (PDP) through F82H coated with two different types of tungsten coatings, i.e., sputter-deposited tungsten (SP-W) and vacuum plasma-sprayed tungsten (VPS-W) has been studied in the temperature range of 300 -550 C. It has been found that hydrogen isotopes PDP fluxes through VPS…
atm at 750 °C. For relatively large grain sizes, the stress values agree well with the amount of expansion induced by oxygen non-stoichiometry (chemical expansion) predicted by a thin film defect equilibria model that was developed previously. The compositional stresses were found to increase with decreasing grain siz…
A microfluidic device was used to examine the avoidance response of a freshwater algae to engineered nanoparticles.
We investigate the glass and the jamming transitions of hard spheres in finite dimensions d, through a revised cell theory, that combines the free volume and the Random First Order Theory (RFOT). Recent results show that in infinite dimension the ideal glass transition and jamming transitions are distinct, while based…
A convenient synthetic route of poly(3HB- <italic>co</italic> -3HH- <italic>co</italic> -SEB) terpolyesters has been reported.
Polarization switching and fatigue properties of BNTM ferroelectric thin films were studied from 100 to 475 K. A combination of impedance spectra and PFM techniques was used to analyze the mechanisms of the dependence on temperature from 200 to 475 K.
Comprehending the mechanism of corrosion film growth on the anode in electrolytes is a foundation in the tailoring of a desirable delayed action in magnesium–manganese dioxide (Mg/MnO 2 ) primary batteries. The formation and growth evolution of the corrosion film on AZ63 magnesium alloys in 2 mol L −1 MgSO 4 aqueous s…
Azulene-substituted tetracyanobutadienes (AzTCBDs) and dicyanoquinodimethanes (AzDCNQs) connected with naphthalene cores were prepared by the reaction of 1-azulenylalkynes with tetracyanoethylene (TCNE) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) in a formal [2 + 2] cycloaddition-retroelectrocyclization. The character…
The thermal stability of graphene has a close relationship with defect generation, thermal oxidation, which in turn have a significant bearing on its properties and applications. This report discusses the effect of confocal laser heating on the structure of single-layer graphene (SLG) on the basal plane and the edge.…
The tilt angle of smectic C phases can be controlled by external forces of very different nature. In particular near a smectic A-smectic C transition, it is susceptible to temperature changes. It can be influenced with electric fields (electroclinic effect), and even mechanically by intra-layer stresses in elastomers.…
