the presence of van der waals (vdw) force can lead to mechanical instability in freestanding nano-scale actuators. most of the previous researches in this area have exclusively focused on modeling the instability in actuators with one actuating components. while, less attention has been paid to actuators consist of two actuating components. herein, the effect of the vdw force on the instability...
In the framework of the dialog between P systems and Microbiology, in this paper we focus on the magnetotactic behavior of magnetotactic bacteria, namely the orientation along the Earth’s geomagnetic field lines. Magnetic properties and magnetotactic behavior could be used to obtained microand nanoactuators for the desired distribution at nanometer level of either intact magnetotactic bacteria ...
STUDY OBJECTIVE We determine the number and location of freestanding emergency departments (EDs) across the United States and determine the population characteristics of areas where freestanding EDs are located. METHODS We conducted a systematic inventory of US freestanding EDs. For the 3 states with the highest number of freestanding EDs, we linked demographic, insurance, and health services...
Robotic manipulation at the nanometer scale is a promising technology for structuring, characterizing and assembling nano building blocks into nanoelectromechanical systems (NEMS). Combined with recently developed nanofabrication processes, a hybrid approach to building NEMS from individual carbon nanotubes (CNTs) and SiGe/Si nanocoils is described. Nanosensors and nanoactuators are investigate...
Freestanding emergency departments (EDs), which offer emergency medical care at sites separate from hospitals, are a rapidly growing alternative to traditional hospital-based EDs. We evaluated state regulations of freestanding EDs and describe their effect on the EDs' location, staffing, and services. As of December 2015, thirty-two states collectively had 400 freestanding EDs. Twenty-one state...
Recently, freestanding lms have attracted much attention because they are highly useful in the fabrication of various nanodevices. Freestanding lms can be used on any substrate without deterioration of their own unique properties. Layerby-layer (LBL) deposition has been used widely in the synthesis of freestanding lms, especially of polymer lms with specic physical and mechanical propertie...
among the intermolecular interactions, the casimir and van der waals forces are the most important forces that highly affect the behavior of nanostructures. this paper studies the effect of such forces on the adhesion of cantilever freestanding nanostructures. the nanostructures are made of a freestanding nano-beam which is suspended between two upper and lower conductive surfaces. the linear s...
a new modified adomian decomposition method (adm) is utilized to obtain an analytical solution for buckling of the nanocantilever actuators immersed in liquid electrolytes. the nanoactuators in electrolytes are subject to different nonlinear forces including ionic concentration, van der waals, external voltage and electrochemical forces. the duan–rach modified adomian decomposition method is ut...
