Hip prosthesis is a complex mechanical biotribosystem with multiple functions. Under the action of cyclic dynamic loadings, developed in a biological adversely environment, it can lose the optimal functionality during the time. To improve mechanical characteristics of hip prostheses we deposited TiN films on SS316Lsteel substrates by pulse laser deposition method (PLD). Adhesion strength of the layer on the substrate was evaluated by scratch tests accompanied by different microscopy methods. Following these studies, we believe that the essential factor for increasing the hardness of femoral heads with thin layers is to provide a strong adherent coating to the substrate using PLD. © 2014 Published by Faculty of Engineering.

This paper initiates the launch and the integration of a new scientific concept: "Mechatronics galaxy", a support of industrial research for European sustainable and strategic development. This new concept is based on achievement and development of generative, evolutionary and integrative-synergistic concepts regarding micro nano mechanics engineering, micro nano electronics engineering and micro nano IT engineering for: spatial, temporal and functional integration, intelligent adaptive behavior based on perception, self-learning, self-diagnostics and systemic reconfiguration, adequate flexibility of software and hardware structures, predictive development of micro nano mechatronics structures (μ nano mechatronics) and of the intelligent computerized applicability with high value added, simultaneous mix-integrative design of micro nano products (un-products), micro nano systems (μ nano systems) and micro-nanotechnologies (μ nano technologies), a strategy of technological, economic and ecological impact in economy. industry and society. Thus, the new concept Mechatronics galaxy» creates and develops micro-nanomechatronics engineering (μnmechatronics engineering), based on fundamental and applied techniques: micro-nanomechatronics (μn-M). micronanorobotics (μn-R), micro-nanointegronics (μn-I), micro-nanosensoristics (μn-S), micro-nanoactuators (μn-A), micro-nanoprocessing (μn-P) and intelligent micro-nanomanufacturing (μn-Fi).

This paper is about aspects and theory regarding nonlinearity effectc on static and dynamics performance of MEMS. Micro-Electro-Mechanical Systems is relatively a new concept in engineering filed but it was started around 1970s as an investigative interest of Si foundry engineering to the quite peculiar properties of mono-crystalline Si. MEMS gained significant momentum when useful devices became commercially available. Important steps have been taken in the field of micro- and nano-structures by developing micro-components of complex organic structures and micro-components of micro- and nano- polymers and dendrimers, with high micro-mechanical and micro-optic properties by applying new advanced technologies and an ultra-precise architecture at micro and nano level. Nonlinear behavior of micro-mechanical systems is an interesting and little explored area of research. Although, micro-system technologies is new and fast developing area, there is little work carried out on modeling and simulation of MEMS devices which concerns their non-linear behavior. Nonlinear modeling of MEMS devices is based on observations related to the micro-systems performance which is often far away from linearity in MEMS devices. There are two types of components that are extensively used in MEMS design: micro-beams (cantilever type) and micro-plates. Manufacturing as well as usage of these components are advantageous to MEMS applications. The main applications of such structures include micro-sensors and micro-actuators. Large deflection of micro-cantilever beams under electrostatic force is studied. Pull in voltage as a phenomenon was widely studied in conjunction with MEMS. Large deflection of micro-cantilever beams under electrostatic field with the application of a voltage very closed to pull in voltage is studied in this work and it is shown that pull in voltage provided by the nonlinear analysis is different of the one yield by the linear analysis and more accurate when compared to the experimental values. © 2014, Editura Cefin.

Research in Micro-Nano-Robotics comprises a very broad field and an advanced scientific field highlighting thus the "robotic/micro-nano-robotic science and engineering ", which has developed and develops technical, technological, measurement/control, inspection micro-nano-robots, robots fulfilling functions vital to human beings, robots delivering ultra-precise medical services, etc. This research, applied in all these areas and other areas still not mentioned, now passes to a higher development phase, in accordance with the development of electronics/microelectronics, mechatronics/micro-nano-mechatronics and computer science/micro-nano computer science, called Micro-Nano-Robotics. Micro-Nano-Robotics, in its evolution, especially in its future evolution, develops in accordance with the development of micro-nanotechnologies and micro-nano-materials, predicting for the future, a „Micro-Nano-Robotics at human anatomy level" and generating for the future "a population and a humanoid new society ". So, we need to define Robotics in general and especially Micro-Nano-Robotics. © 2014, Editura Cefin. All rights reserved.

Innovations in the field of intelligent micro-nano-fabrication created unique opportunities for micro-nano-products for micro-nano-processing on micro and nano scale micro-nano-structures. This micro-nano-size range is applicable to new electronic, optical, magnetic, mechanical, chemical and biological micro-nano-devices, to micro-nano-sensors, for control, etc.. Important techniques used to manufacture micro-nano-fabrication structures occur in a range from a few microns to a few nanometers. Important steps have been taken in the field of micro- and nano-structures by developing micro-components of complex organic structures and micro-components of micro- and nano- polymers and dendrimers, with high micro-mechanical and micro-optic properties by applying new advanced technologies and an ultra-precise architecture at micro and nano level. Trends regarding these micro- and nano-components, refer to future research for obtaining new micro- and nano-technological steps, to address the new blocks of copolymers in molecular and atomic compositions, to address the new new nano-crystalls for obtaining new method, semiconductors, magnets, by colloidal chemical processes and micro-technologies and condensed matter physics. Obtaining new materials, also as a future trend, has been driven by scientific discoveries in which the most important was the discovery of "carbon nano-tubes", which applies in building matrices for the discovery of new materials, benefitting not only from the construction, topology of interatomic bonds, but also from the absence of surface effects, together with excellent electrical, optical and mechanical properties. © 2014, Editura Cefin.
