Highly stabilized monodispersed silver nanoparticles (AgNPs) were synthesized by Rhizopus stolonifer and the antifungal efficacy of silver nanoparticles (AgNPs) against Candida sp. were studied. Characterization of biosynthesized nanosilver was made by TEM-EDS and AFM. Minimum Inhibitory Concentration (MIC) of biosynthesized AgNPs, Amphotericin B, and Fluconazole have been studied on pathogenic...
In response to rising demand for high performance actuators to serve nano-technology, a linear ultrasonic motor was designed and constructed to verify its potential as a viable nano-actuator. After establishing the analytical model that elucidates the physics of the ultrasonic motor operation, experimental performance tests were conducted in a fully digital controlled real-time control environm...
We investigate the PL characteristics of the equivalent-size controlled Si-QDs by employing the nano-porous AAO membrane as the template for growing Si-rich SiOx nano-rods to achieve the spatially confined synthesis of Si-QD. The ultra-bright PL can be emitted from the SiOx nano-rod in nano-porous AAO membrane. In addition, we preliminarily demonstrate the in-situ high-temperature synthesis of ...
This paper aims to explore the antibacterial property of nano Ag/TiO2 coating bracket for the common bacteria in oral cavity, and discuss its biocompatibility. Micro morphology in the surface of nano Ag/TiO2 coating bracket was detected by scanning electron microscope (SEM), and surface roughness of ordinary mental bracket, nano TiO2 coating bracket and nano Ag/TiO2 coating bracket were measure...
The main objective of this paper is to develop a multiscale method for the static analysis of a nano-system, based on a combination of molecular mechanics and MLPG methods. The tangent-stiffness formulations are given for this multiscale method, as well as a pure molecular mechanics method. This method is also shown to naturally link the continuum local balance equation with molecular mechanics...
Compliant bridge mechanisms are frequently utilized to scale micrometer order motions of piezoelectric actuators to levels suitable for desired applications. Analytical equations have previously been specifically developed for two configurations of bridge mechanisms: parallel and rhombic type. Based on elastic beam theory, a kinematic analysis of compliant bridge mechanisms in general configura...
background: misoprostol, a prostaglandin e1 analogue compared to prostaglandin e2, has the advantage of being inexpensive and stable at room temperature, with its proven efficacy and safety. however studies on the effect of ph on the efficacy of misoprostol have yielded conflicting results. thus its use in the induction of labour in patients with premature rupture of membrane requires further i...
The architecture optimization of a newly designed flexure XY parallel micro-manipulator with both input and output decoupling is conducted in this paper. In view of the compliance of flexure hinges, the input stiffness model of the motion stage are established based upon the matrix method, and then the dynamic equation is derived through the Lagrangian approach, which is verified by the modal a...
We used sub-micron metal rod decorated surfaces, 'nano-lawn' structures, as a substrate to study cell-to-cell and cell-to-surface interactions of primary murine astrocytes. These cells form thin membranous tubes with diameters of less than 100 nm and a length of several microns, which make contact to neighboring cells and the substrate during differentiation. While membrane protrusions grow on ...
This study examines how differentiation of human mesenchymal stem cells regulates the interaction between the cell membrane and the actin cortex controlling cell behavior. Micropipette aspiration was used to measure the pressure required for membrane-cortex detachment which increased from 0.15 kPa in stem cells to 0.71 kPa following chondrogenic differentiation. This effect was associated with ...
