This paper presents size dependent stability analysis a cantilever Micro laminated Beam embedded in elastic medium by using the modified coupled stress theory which includes the length scale parameter. The Micro Beam subjected to compressive load is considered as three composite laminas and embedded in elastic medium which is modelled in the Winkler foundation model. In the obtaining of the governing equations, the energy principle is used. In the solution of the buckling problem, the energy based Ritz method is implemented with algebraic polynomials. In order to accuracy obtained expressions and used method, a comparative study is performed. Many parametric studies are presented in order to investigate the buckling of laminated Micro Beams. For this purpose, effects of stacking sequence of laminas, geometric parameters, length scale parameter, fiber orientation angle, the parameter of elastic medium on critical buckling loads of laminated Micro Beams are investigated.

In the present work, the mathematical model of a homogeneous, isotropic thermoelastic double porous Micro-Beam, based on the Euler-Bernoulli theory is developed in the context of Lord-Shulman [1] theory of thermoelasticity. Laplace transform technique has been used to obtain the expressions for lateral deflection, axial stress, axial displacement, volume fraction field and temperature distribution. A numerical inversion technique has been applied to recover the resulting quantities in the physical domain. Variations of axial displacement, axial stress, lateral deflection, volume fraction field and temperature distribution with axial distance are depicted graphically to show the effects of porosity and thermal relaxation time. Some particular cases are also deduced.             

This paper investigates damping ratio in Micro-Beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the Micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined theoretical and numerical studies investigate the permanent magnetic field effect on the damping ratio in clamped-clamped and cantilever Micro-Beams. Furthermore, the influence of the magnetic field intensity on the frequency of the Micro-Beams with thermo-elastic damping effect is evaluated. Such evaluations are used to determine the influence of magnetic field on the vibration amplitude of the resonators. The meaningful conclusion is that the magnetic field increases the equivalent stiffness and thermo-elastic damping and consequently the energy consumption of the resonators.

In this article, in reference to the modified couple stress theory and Euler-Bernoulli Beam theory, the free lateral vibration response of a Micro-Beam carrying a moveable attached mass is investigated. This is a decent model for biological and biomedical applications beneficial to the early-stage diagnosis of diseases and malfunctions of human body organs and enzymes. The Micro-cantilever Beam is composed of functionally graded materials (FGMs). The material properties are supposed to show variations through-thickness of the Beam in consonance to the power of law. Rayleigh-Ritz method is applied in order to explore the natural frequencies of the first three vibration modes. In order to manifest the accuracy of the proposed method, the results are established and juxtaposed with technical literature. Influences of the material length-scale parameter that captures the size-dependency, ratio of the mass of the Beam to the mass of the attached mass and power index of the graded material consequent to the vibrational behavior of the system are contemplated. This technical research denotes the value of the material gradation besides to the inertia of an attached mass in the dynamic behavior of the bio-Micro-systems. As a result, the adoption of suitable power index, mass ratio and position of the attached mass lead to the superior design of bio-Micro-systems persuading early-stage diagnostics.

Organic class of 2,4-difluroanisole-24DFANIS materials of macro/Micro class is reported here mainly for sensory uses; the elemental analysis of the organic 2,4-difluroanisole (24DFANIS) has been studied to ensure the presence of the elements along with their proportions in % by theory and practice. The structural computational effect of 24DFANIS for nano-device fabricated of 25 nm applications is measured and the corresponded data of computational elucidation of the 24DFANIS structure is reported. The sensor work of red LED based enhanced work for macro (thick film) and Micro (thin film) 24DFANIS is measured and reported at room temperature effectiveness at 29.2 oC with 54% humidity for both the specified cases. The main aim of the work is to confirm the sample atoms and proceed for nano-tubular work as well as sensor analyses.

Nanotechnology, shortened to nanotech, is the study of the controlling of matter on an atomic and molecular scale. Generally, nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension and involves developing materials or devices within that size. The use of nanotechnology in the field of pharmaceutics and drug delivery has grown over the last few years, so remarkably that the pharmaceuticals developed on the basis of this technology are termed as Nanopharmaceuticals. Among the nanopharmaceuticals currently being used or under investiga­ tion, one can mention nanoemulsions, nanosuspensions, nanospheres, carbon nanotubes, micellar nanocarriers (polymeric micelles), nanocapsules, lipid nanoparticles, self-nanoemulsifying systems, dendrimers, etc.

The nonlinear pull-in behavior for different electrostatic Micro-actuators is simulated in this work. The difficulty of nonlinear equation is overcome using the differential quadrature method and Wilson−q method. Several characteristics of different combination of shaped fixed-fixed Beam and curved electrode are also observed to optimize the design in this paper. The nonlinear deflection of uniform actuator and non-uniform actuator solved using the differential quadrature methods are efficient. The stresses are determined for this par electrostatic Micro-actuator design. The effects of applied voltage, squeeze film force, external loading and residual axial loading on the behavior of the electrostatic actuator are investigated. It is needed to consider the squeeze film force and residual axial loading in the fixedfixed Micro-actuator design.
