ABSTRACT In this study, to make a stable electrode material for a supercapacitor, we selected a polyaniline and titanium dioxide (TiO 2 ) hybrid material. Peroxotitanium acid was used to oxidize aniline in the presence of sulfuric acid to a poly(aniline sulfate) salt–titanium oxide composite in one step. IR, X‐ray dif…
The use of agricultural residues for particleboard manufacturing increases their value-add and help meet the growing demand of raw materials for the panel industry. Accordingly, the aim of this study was to assess the quality of particleboards produced only with sugarcane bagasse or along with P inus and E ucalyptus w…
K+–Na+ ion-exchanged channel waveguide has been fabricated in Nd3+ doped aluminum germanate (NMAG) glasses with potential photosensitive property. The channel waveguide exhibits single mode at 1.3μm and the mode field diameters were measured to be horizontally 10.1μm and vertically 5.3μm, respectively. Amplified spont…
ABSTRACT The effects of treatment pressure on the structures and properties of PMIA fiber were investigated by Scanning electron microscopy, Dynamic wetting measurements, Fourier transform infrared spectrometry, X‐ray diffraction, thermogravimetric analysis, and mechanical properties test technology in supercritical c…
Supramolecular polymers with orthogonal interactions are of broad interest, and reports on such materials with multifunctional stimuli-responsive behavior are rare. Polymer blends based on a poly(ethylene- co -butylene) core (PEB) terminated with either 2-ureido-4[1 H ]-pyrimidinone (UPy) hydrogen-bonding motifs (UPy-…
Varying the solvent offers a simple way to control superstructure polymorphism of a tri-β <sup>3</sup> -peptide-based supramolecular system.
Doxorubicin is an effective chemotherapeutic drug, however, its toxicity is a significant limitation in therapy. Encapsulation of doxorubicin inside liposomes or ferritin cages decreases cardiotoxicity while maintaining anticancer potency. We synthesized novel apoferritin- and liposome-encapsulated forms of doxorubici…
Using shadow photography, we observed microsecond time scale evolution of multiple cavitation bubbles, excited by tighty focused femtosecond laser pulse in water under supercritical power regime (~100 Pcr). In these extreme conditions high energy delivery into the microvolume of liquid sample leads to creation of sing…
Time-dependent density functional theory combined with Ehrenfest dynamics are employed to calculate electronic energy loss of energetic ions in two-dimensional graphene and white graphene (BN) targets. Special attention is paid to the effects of different electronic structures on their stopping power. Our results show…
Layered $5d$ transition metal dichalcogenide (TMD) $\mathrm{IrT}{\mathrm{e}}_{2}$ is distinguished from the traditional TMDs (such as $\mathrm{NbS}{\mathrm{e}}_{2})$ by the existence of multiple charge-density wave (CDW)-like stripe phases and superconductivity at low temperatures. Despite intensive studies, there is…
In this study, atmospheric corrosion behaviour of pure Al 1060 after 1–48 months of exposure in a tropical marine environment was studied. The corrosion kinetics was evaluated by weight loss measurement and pit depth calculation. The rate controlling steps as well as the effect of the native oxide film and the corrosi…
ABSTRACT Exfoliatied kaolinite (E‐Kaol) was prepared by intercalating DMSO and KAc into kaolinite successively followed by irradiation under ultrasonic. The modified kaolinite was then introduced to polypropylene (PP) by melt blending in order to improve the fire performance of the composite. The flammability and ther…
Thermoplastic expandable microspheres (TEMs) having core/shell structure were prepared via suspension polymerization with vinylidene chloride (VDC), acrylonitrile (AN), and methyl methacrylate (MMA) as monomers and i-butane as blowing agent. TEMs were about 20 µm in diameter and had a hollow core containing i-butane.…
The design of multiresponsive systems continues to arouse a lot of interest. In such multistate/multifunctional systems, it is possible to isomerize a molecular system from one metastable state to another by application of different stimulation such as light, heat, proton, or electron. In this context, some researches…
We probe the mechanical shear and compression properties of hydrogen-bonded polymer multilayers directly assembled at the oil-water interface using interfacial rheology techniques. We show that the polymer multilayers behave mechanically like a transient network, with elastic moduli that can be varied over 2 orders of…
TiO2 electrodes loaded with Au-Ag alloy nanoparticles, Ag content of which is about 0.25-0.90, exhibit stable anodic photocurrents due to plasmon-induced charge separation (PICS) in the presence of an electron donor. The PICS wavelength is blueshifted and the PICS efficiency is enhanced by increasing the Ag content in…
An iterative transform method is proposed for solving the phase problem in protein crystallography. In each iteration, a weighted average electron-density map is constructed to define an estimated protein mask. Solvent flattening is then imposed through the hybrid input-output algorithm [Fienup (1982). Appl. Opt. 21,…
Three optically transparent colorful (red, green, and blue) glasses were synthesized by the sol-gel method. Nano-sized precipitates were found in scanning electron microscopy images. The precipitates were analyzed by transmission electron microscopy (TEM) and high resolution TEM. The measured lattice parameters of the…
A new metal borohydride ammoniate (MBA), Zr(BH4)4·8NH3, was synthesized via ammoniation of the Zr(BH4)4 crystal. Zr(BH4)4·8NH3 has a distinctive structure and the highest coordination number of NH3 groups among all the known MBAs. This compound could quickly dehydrogenate at 130 °C, enabling it a potential hydrogen st…
Sr-doped lanthanum manganite (LSM) is a widely used cathode material in solid oxide fuel cells (SOFC). Despite being a poor ion conductor, LSM electrodes can reduce oxygen via two pathways: a "3PB surface path" which includes surface diffusion of oxygen species and oxide ion incorporation at the three phase boundary (…
