Nowadays, due to the growing need of the human to further improve the health of the community, research in the field of pharmacology as well as simulation of the cell culture environment is increasing. One of the most important requirements for simulating cell culture is the use of concentration gradient in culture media. The reason for this is the dependence of cellular activity on the presence of a gradient of concentration in the environment. Also, in drug investigations, in order to speed up the examination of different drugs and reduce the amount of drug that will used, different concentrations of the drug should be considered simultaneously in the microchips. Therefore, to make the... 

Throughout history, engineers have always been searching for ways to increase the strength-to-weight ratio in the design of engineering structures. Using lattice structures has been a method implemented in different applications to achieve this goal. Herein, two novel hybrid lattice structures are designed, and their compressive quasi-static mechanical behavior is evaluated experimentally and numerically. In one of the designed structures, using dual-phase strengthening, FCC unit cells are incorporated as a reinforcement phase into a BCC matrix. In the multifunctional lattice structure, FCC and BCC unit cells are combined with their central nodes connected. All of the designed structures are...
