IN THIS ARTICLE THE VARIATION OF PRESSURE OF One dimensional HARD ELLIPSES (HE) AND GEY BERN (GB) PARTICLES CONFINED BETWEEN TWO WALLS WITH RESPECT TO WALL SEPARATION IS INVESTIGATED [1-3]. ALSO WE STUDY THE DEPENDENCY OF THIS QUANTITY WITH RESPECT TO THE STRUCTURE OF WALLS. THIS HAS BEEN DOne BY CONSIDERING THREE TYPES OF WALL-PARTICLE INTERACTIONS SUCH AS: HARD WALL; WALL WITH SOFT ELLIPSES INSERTED AT DIFFERENT ANGLES [4]; WALL WITH HARD ELLIPSES INSERTED AT DIFFERENT ANGLES, WHICH CAN INTERACT WITH THE GB PARTICLES OF THE SYSTEM. WE PERFORM THE MONTE CARLO SIMULATION IN NVT ENSEMBLE, FOR A SYSTEM OF CONFINED ELLIPSES AND CHOOSE A 1D SIMULATION LINE. THE PARTICLES CAN ROTATE FREELY IN XY PLANE, WHILE THEIR CENTERS CAN ONLY MOVE IN X DIRECTION. WE CAN RELATE THE PRESSURE OF THE SYSTEM TO THE SOLVATION FORCE BETWEEN TWO NANO CIRCULAR PARTICLES SUSPENDED IN A HARD-ELLIPSE OR GB FLUID. FIGURE 1 SHOWS THE OSCILLATORY BEHAVIOR OF THE SOLVATION FORCE BETWEEN TWO NANO PARTICLES FOR TWO DIFFERENT INTERACTIONS OF HE AND GB. AS IT IS SEEN FROM THIS FIGURE FOR SMALL SEPARATIONS OF THE WALLS AND FOR THE CASE OF HARD ELLIPSES THE SOLVATION IS REPULSIVE WHEREAS FOR THE CASE OF GB PARTICLES IT IS ATTRACTIVE. BUT FOR GREATER VALUES OF WALL DISTANCE THE FORCE GOES TO ZERO, AS EXPECTED.
