In this paper, size-dependent electromechanical behavior of circular nanoplates made of piezoelectric materials is studied with consideration of materials surface properties. Gurtin-Murdoch theory for solid surfaces is used to generalize the classical plate model through an analytical method. Closed-form solutions bas…
Abstract The graft copolymerization of poly(vinyl acetate) [poly(VAc)] onto starch was studied using the KMnO 4 -H 2 SO 4 redox system. The grafting parameters are favored by changing the concentration of KMnO 4 , the concentration of acid, the temperature, the time, and the concentration of monomer. A maximum graft y…
Microstructure stability and electrical properties of Ni(O)–GDC (Ce 0.9 Gd 0.1 O 2-δ ) porous thin films were studied by both in situ X-ray diffraction and in situ impedance spectroscopy during the reduction of NiO into metallic Ni. The initial microstructure of the NiO/GDC porous thin film is composed of particles wi…
Industrial applications of titanium alloys have grown significantly over the years primarily due to their high strength, light weight as well as good fatigue and corrosion-resistance properties. Since these alloys are hard-to-machine, there is an obvious demand to develop simulation tools in order to analyse the mater…
In this work, the PbZr0.52Ti0.48O3/La0.625Ca0.375MnO3 (PZT/LCMO) thin films show a large magnetodielectric effect up to 52% at 3 MHz in a field of 0.8 T near the ferromagnetic Curie temperature Tc of LCMO. According to the equivalent RC-circuit fitting, the large magnetodielectric effect is found to be closely related…
The localized surface plasmon resonance (LSPR) of silver nanoparticles during immobilization on the U-bent sensor fiber probe has been studied. The gradual wavelength shift of the peak resonance due to the increment of the number of nanoparticles on the fiber surface has been attributed to the plasmonic coupling effec…
We use polymer self-consistent field theory to study the physics involved in the permeation of charged dendrimer molecules across anionic lipid bilayer membranes. We specifically examine the influence of dendrimer shape deformations, neutral grafts, and pH conditions on the interactions between dendrimers and membrane…
Representative volume element-based three-dimensional models with various nanofiller geometries and process parameters are presented for the design and analysis of composite materials. Analytical, computer-aided design, and computer-aided engineering tools are integrated to develop user interface tools with automated…

The application of commercially available carbon materials (nanotubes and porous carbons) for the preparation of drug delivery systems is studied. We used two types of carbon nanotubes (CNT) and two activated carbons as potential materials in so-called hot-melt drug deposition (HMDD). The materials were first studied…
Highly dendritic graphene crystals up to 0.25 mm in diameter are synthesized by low pressure chemical vapor deposition inside a copper enclosure. With their six-fold symmetry and fractal-like shape, the crystals resemble snowflakes. The evolution of the dendritic growth features is investigated for different growth co…
We report on the influence of localized surface plasmon resonance excitation of Au@SiO 2 core–shell nanoparticles on the amplified spontaneous emission of a semiconductor polymer composite (F8BT/MEH-PPV). Au@SiO 2 nanoparticles are compatible with the donor–acceptor polymer matrix and get uniformly distributed within…
Microstructure reconstructions resulting from diffraction contrast tomography data of polycrystalline bulk strontium titanate were reinvestigated by means of electron backscatter diffraction (EBSD) characterization. Corresponding two-dimensional grain maps from the two characterization methods were aligned and compare…
Although all graphites share the same idealized chemical structure, marked differences in fact exist between their reactivities, such as the propensity for oxidation, that need to be taken into consideration for the development of applications. Here we show that five different commercially sourced natural and syntheti…
We report 2 cases of patients who presented with blue macules clinically suspicious for blue nevi. One patient had no documented history of trauma or silver exposure, and the other reported exposure to silver over 30 years ago. Microscopic examination revealed a dermal population of brown-black globules predominantly…
We investigate the effect of the isomerization rate f on the microscopic mechanisms at the origin of the massive mass transport found in glass-formers doped with isomerizing azobenzene molecules that result in surface relief gratings formation. To this end we simulate the isomerization of dispersed probe molecules emb…
Visible emission from ZnO is usually broadband and realizing line emission from rare earth f?f transitions in ZnO at room temperature has proven to be difficult. A controlled solid-state reaction process with different standing times to synthesize rare earth doped (Nd3+) zinc oxide (ZnO) has shown that sharp and inten…
Size- and shape-controllable Ag2Se-ZnS nanorods (NRs) and nanowires (NWs) have been synthesized successfully by the solution-liquid-solid (SLS) method. By using Ag2Se nanocrystals (NCs) as seeds and catalyst, colloidal Ag2Se-ZnS NRs and NWs with controllable diameters and lengths in ranges of 5-12 nm and 15-600 nm wer…
We developed a novel hyperthermia material for cancer therapy, cationic albumin-conjugated magnetite nanoparticles (MNPs), which absorb the energy of an alternating magnetic field and convert it into heat. MNPs of about 10 nm were synthesised through co-precipitation, and citric acid was used to stabilise the MNP susp…
The design and fabrication of hollow polymer microspheres responsive to various stimuli comprises a promising approach for the development of multifunctional and efficient systems for various nanomedicine-related applications. In this paper, we present the preparation of poly(methacrylic acid-co-N,N'-methylenebis(acry…
