A facile method has been developed to synthesize Au/Pd core-shell nanoparticles via galvanic replacement of Cu by Pd on hollow Au nanospheres. The unique nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, ultraviolet-visible spectroscopy, and elec…
PURPOSE: To evaluate in vivo ocular safety of an intravitreal hydrosilylated porous silicon (pSi) drug delivery system along with the payload of daunorubicin (DNR). METHODS: pSi microparticles were prepared from the electrochemical etching of highly doped, p-type Si wafers and an organic linker was attached to the Si-…
For the purpose of investigating the microstructure evolution and deformation behavior of magnesium under high strain rates, the Split Hopkinson Pressure Bar (SHPB) apparatus was used under high strain rates from 755 s−1 to 2826 s−1 in the present work at room temperature. The microstructures of extruded Mg-Gd-Y Magne…
A misfit layer sulfide (BiS) 1.2 (TiS 2 ) 2 with a natural superlattice structure has been shown to be a promising thermoelectric material, but its high carrier concentration should be reduced so as to further optimize the thermoelectric performance. However, ordinary acceptor doping has not succeeded because of the n…
The development of methods for controlling the architecture of ensembles of micro- and nano-particles via affecting the processes of their self-assembly in a drying drop of solution is an urgent problem in modern fundamental (theory of ordering in a dissipative system) and applied (design of microstructures and materi…
In this paper we describe an unusual electrochemical phenomenon, namely, cathodic corrosion of platinum. We show that all existing models of cathodic corrosion are inconsistent with our experimental observations. Therefore, we present a new model of cathodic corrosion, which is based on the assumption that metal anion…
Lithium hydride has high hydrogen capacity (12.7 mass %), but could not be considered as practical hydrogen storage media because of being very stable (required 900 °C for 0.1 MPa desorption pressure). Recently, C and Si have been found suitable to reduce the stability of LiH. This motivates us to investigate the prop…
The critical behaviour of Mn0.94Nb0.06CoGe alloy around the paramagnetic-ferromagnetic phase transition was studied based on the field dependence on magnetic entropy change. By using the obtained exponents, the modified Arrott plot is consistent with that by using conventional method. These critical exponents are conf…
The first-principles projector-augmented wave method employing the quasi-harmonic Debye model, is applied to investigate the thermodynamic properties and the phase transition between the trigonal R 3 c structure and the orthorhombic Pnma structure. It is found that at ambient temperature, the phase transition from the…
Naturally existing biological materials have been garning considerable attention as environmentally benign green-nanofactories for the fabrication of diverse nanomaterials, and with desired size and shape distributions. In the present investigation, we report the size and shape controllable biofabrication of silver na…
Since the discovery of giant magnetocaloric effect in MnFeP 1− x As x compounds, much valuable work has been performed to develop and improve Fe 2 P-type transition-metal-based magnetic refrigerants. In this article, the recent progress of our studies on fundamental aspects of theoretical considerations and experiment…
A new approach, an invisible template method that is realized through controlling the interface electroconductivity of an electrode surface, is presented to synthesize gold regular arrays of nanoflowers with variable separations through further electrochemical deposition. Using polystyrene monolayer colloidal crystals…
Water-based carbon nanotube (CNT) is highly desirable for inkjet printing devices due to its environmentally benign and low-cost features. To improve the dispersion of CNT in water, oxygen-containing functional groups are introduced into the surface of CNT via an acid oxidation process. The CNT-based gas sensor is fab…
This paper is aimed to describe a simple and rapid eco-friendly bottom-up approach for the preparation of antioxidant silver bionanostructures using a leaf extract from sage (Salvia officinalis L.). The bioreduction property of sage in the synthesis of silver nanoparticles was investigated by UV-VIS and Attenuated Tot…
The catalyst-free Diels-Alder synthesis of polyphenylene dendrimers with a chromophore core has now been demonstrated to achieve the seventh to ninth generations upon divergent growth. Since standard analytical tools such as size-exclusion chromatography do not provide realistic molecular weights, MALDI-TOF mass spect…
Biofouling resulting from the attachment of microorganisms communities to the membrane surface is the major obstacle for the widespread application of membrane technology. This work develops a feasible approach to prepare an anti-biofouling poly(vinylidene fluoride) (PVDF) membrane. A copolymer that possessed opposite…
Tracks formed by swift-heavy ion irradiation, 2.2 GeV Au, of isometric Gd2Ti2O7 pyrochlore and orthorhombic Gd2TiO5 were modeled using the thermal-spike model combined with a molecular-dynamics simulation. The thermal-spike model was used to calculate the energy dissipation over time and space. Using the time, space,…
Sulfonated chitosan (S-CTS) doped polyaniline (PANI) was synthesized by “template-free” method successfully, and it is reported as corrosion inhibitor for the first time. The corrosion inhibition property of PANI was demonstrated for mild steel in acidic environment using weight loss test, Tafel polarization, electroc…
Supercapacitor assisted low dropout regulators (SCALDO) were proposed as an alternative design approach to DC-DC converters, where the supercapacitor circulation frequency (switching frequency) is in the order of few Hz to few 10s of Hz, with an output stage based on a low dropout regulator stage. For converters such…
Controlling the nanostructure of self-assembled block copolymer thin films is critical for applications in nanotemplate design, nanoporous membranes, and organic optoelectronics. In this study, we employed a gradient approach to examine the effects of substrate surface chemistry and film thickness on the self-assembly…
