It is recognized that topographical features such as ridges and grooves can dramatically influence cell phenotype, motivating the development of substrates with precisely biomimetic topography for study of the influence on cultured cells. Intestinal basement membrane topography has been precisely replicated using plas…
El objetivo de este trabajo ha sido evaluar por comparación, las características de las ferritas de Ni y Mn, que han sido obtenidas partiendo de sus óxidos básicos por vía mecanosíntesis. El proceso se llevó a cabo a temperatura ambiente, en vacío; como medio de molienda esferas de acero de 3 mm de diámetro y frascos…
Physically crosslinked Polyurethane-b-polyacrylamide (PU-b-PAAm) hydrogels have been synthesized using dithiocarbamate (DC)-based polyurethane macroiniferter (PUMI). The prepared materials have been characterized using GPC and spectroscopic analysis. The detailed transport behavior of these hydrogels has been investig…
Carbon nanotubes (CNTs)/diamond composite were synthesized by microwave-sintering method and the field emission property was studied. The binding energy of two materials become larger and the carbonization of the diamond less, compare to sintering in the common tube furnace. Scanning electron microscopy (SEM) was used…
The dissipative particle dynamics simulation is usually used to study polymer in mesoscopic space. The traditional methods are resource intensive, especially when the scale of research is large. Therefore, improving computing efficiency is a key point in this research area. Two major issues are addressed in this paper…
Nanotechnology research and product development is actively conducted in many industries, for example, in manufacturing, electronics, and health sectors. As many research studies show, the construction industry follows these trends, but does not take a leadership role in most of the current efforts in Nanotechnology.…
(Mg0.88, Fe0.12)SiO3, (Mg0.86, Fe0.14)(Si0.98, Al0.02)O3 perovskites were studied using Fe K-edge X-ray Absorption Near Edge Spectroscopy (XANES) under pressure up to 85 GPa at ambient temperature. The amount and quality of the data collected allows to perform for the first time a systematic study of the absorption ed…
For use in ultrasonic actuators, we investigated the structural and piezoelectric properties of $(1\;-\;x)Pb(Zr_{0.515}Ti_{0.485})O_3$ - $xPb(Sb_{1/2}Nb_{1/2})O_3$ + 0.5 wt% $MnO_2$ [(1 - x)PZT - xPSN + $MnO_2$ ] ceramics with a variation of x (x = 0.02, 0.04, 0.06, 0.08). All the ceramics, which were sintered at $125…
A metamaterial rectangular tap design is introduced and numerically simulated. The tap proves its efficiency in improving light tapping compared to taps composed of positive-index materials. The tapped beam is narrow for efficient collimation. In addition, the tapped light power can be easily controlled by adjusting t…

The protection for copper tarnish was developed by surface treatment method and volatile corrosion inhibiting (VCI) technology. The performance of surface treatment and VCI material is also examined in simulated test environment. Benzotriazole (BTAH) solution that contained molybdate showed best performance than other…
A continuum based microstructural modeling of particle-reinforced composites including length-scale is presented. The proposed method features finite-element representation of the particles in a matrix along with their size dependent strengthening due to geometrically necessary dislocations (GND), which is punched to…
A new targeted therapy has been developed to deliver chemotherapy directly to the lymph nodes for treatment of lymphatic metastasis. Localization of the treatment was accomplished by using calcium phosphate (CaP) nanoparticles as the delivery vehicle. The CaP-nano conjugates, with adsorbed chemotherapy on the particle…
Phase transition in ferroelectric polymer is very interesting behavior and has been widely studied for real device applications, such as actuators and sensors. Through the phase transition, there is structural change resulting in the change of electrical and optical properties. In this study, we fabricated the Febry-P…
Helical Rosette Nanotubes (HRN) are novel biomimetic self-asssembled supramolecular, whose DNA base-pairs (G & C) can solidify in water under physiological conditions. Due to electrostatic force and interactions effects, a stable stack with an inner channel 11aring in diameter is formed. Because of their hollow struct…
The emission property of Y2O3-Mo emitter depends on the contentration of Y2O3. Y2O3-Mo with 4wt% Y2O3could be used as a thermionic emitter and that with higher content of Y2O3(> 10wt%) could be served as a secondary emitter.
In this paper, the experiences on full field EUVL lithography are reviewed. Besides the imaging performance of the EUV ADT at IMEC, also the progress in resists and reticles are discussed and compared to the production requirements for EUV lithography.
This paper presents the new balanced front-end SAW modules with the improved selectivity at the low frequency offsets and fractional bandwidth of 1.5–4% for the 440–470 MHz handheld transceivers. The modules contain 2 SAW filters connected across a low noise bipolar transistor amplifier. The balanced longitudinally-co…
Iron oxide nanoparticles are promising candidates for drug delivery systems to treat osteoporosis due to their biocompatibility and magnetic properties. Magnetite and maghemite nanoparticles were synthesized here using a co-precipitation method. The particles were characterized by transmission electron microscopy (TEM…
Purified carbon nanotubes (with removed toxic catalytic particles) have been considered as novel materials for drug delivery and for generating artificial organs more efficiently due to their unique surface features. Traditionally, the surface chemistry of carbon nanotubes has been modified through various functionali…
