However, there are some challenges related to the shape and size modifications required to suffice the applications. The alloy needs improvements particularly in the areas of porosity for bone replacement, radiopacity, super elasticity and fatigue strength. There is a wide range of applications of biocompatible Porous NiTi alloys in the areas of inter body fusion devices, synthetic bone grafting, etc. Although it cannot be denied of the possibility of high corrosion factor of Porous NiTi alloys as compared to solid NiTinol due to greater surface area in contact with the body fluids. Such cases include definite surface preparation to cater to the need for increased biocompatibility. This paper includes the synthesis of porous NiTi alloys through the sintering process along with a check of the surface treatments and its effects on the properties related to corrosion of Porous NiTinol. The Alloys were subjected to different treatments like dry heating, boiling in water and passivation. The corrosion resistance, after and before the treatments were evaluated.</p> 2020-03-18T21:15:29+00:00 ##submission.copyrightStatement## https://www.fundamentaljournals.org/index.php/ijfps/article/view/256 Gravitational force and fallacy of space deformation 2020-03-19T08:37:36+00:00 Enrique Martinez Viladesau emviladesau@gmail.com <p style="text-align: justify;">In the present paper, we attempt to explain what we really do not know or understand. For this, we assume to accept approaches that go against reason and common sense. We will try to give a view, about inaccuracy arguments state that the gravity force associated with mass, is caused by the deformation of the space adjacent to it. To move from the real world to the world of fantasy, we only needed to support the misconception of the time dilation in the fallacy of the space deformation. We will use this paper to expose some writings that contribute to masking logical reasoning.</p> 2020-03-18T20:55:17+00:00 ##submission.copyrightStatement## https://www.fundamentaljournals.org/index.php/ijfps/article/view/257 Absolute zero in Casimir vacuum 2020-05-10T22:35:39+00:00 Xingwu Xu xuxingwu@gotion.com.cn <p style="text-align: justify;">Casimir vacuum has many peculiar properties, e.g. the speed of light can exceed c. This paper investigated the behavior of gas molecules in Casimir vacuum. Analysis and calculation indicate that we can get a new absolute zero in Casimir vacuum. This is due to the Hamiltonian, which equals the kinetic energy of the ensemble of gas molecules that is reduced in Casimir vacuum; therefore, the gas constant R is changed. This conclusion has great significance for the research of the vacuum properties.</p> 2020-03-18T20:23:17+00:00 ##submission.copyrightStatement## https://www.fundamentaljournals.org/index.php/ijfps/article/view/251 The Nature of Force and the Dark Matter 2019-10-21T22:05:06+00:00 Xingwu Xu xuxingwu@gotion.com.cn <p style="text-align: justify;">There are different approaches for investigating the force as well as the gravity. Newton emphasized the mathematical meaning of gravity. Einstein’s gravity is geometry. The physical exploring for the gravity is still on the way. Le Sage investigated the nature of gravity, but his theory has many defects. This paper gives out a physical chemistry approach for the nature of force, which bases on gravitons’ reaction by introducing the concepts of Gibbs free energy change and holographic screen. The change of the Gibbs free energy results in the imbalance on the two sides of the holographic screen, it is the force. The change of force as the distance depends on the distribution of gravitons. For solar system, the graviton gas distributes in centre-radical pattern, so the inverse-square law is applicable. But in the galaxies, the distribution of the graviton gas is not in centre-radical, therefore the acceleration is just inversely proportional to the distance (not square of distance), which is equivalent to the centripetal force. The flatness of rotation curve can be explained without dark matter.</p> 2019-10-10T23:38:14+00:00 ##submission.copyrightStatement## https://www.fundamentaljournals.org/index.php/ijfps/article/view/243 Relation of Matter-wave Verified in Diffusion Theory 2020-05-08T15:10:38+00:00 Takahisa Okino okino@oita-u.ac.jp <p style="text-align: justify;">Investigating the elementary process of diffusion yielded the universal expression of diffusivity relevant to the angular momentum of each microparticle in a material. Using the diffusivity obtained then for the diffusion equation, the wave equation of Schreadinger was theoretically derived from the physical concept in Newton mechanics. The derivation itself reveals that any moving microparticle has the wave image as an intrinsic nature. It was theoretically revealed that the relation having been accepted as a hypothesis proposed by De Broglie is really valid for any moving microparticle and also that another relation of matter-wave is possible. The new diffusion theory based on the matter-wave will be useful for further development of the nanotechnology in materials science.</p> 2019-10-07T00:00:00+00:00 ##submission.copyrightStatement## https://www.fundamentaljournals.org/index.php/ijfps/article/view/240 Arrow of time: a physical concept with philosophical roots 2020-03-18T21:54:04+00:00 Behrooz Ebadi behrouzebadi.july1982@gmail.com <p>The notion of “time” is one of the key concepts in physics and philosophy and it “occupies a key role to bridge domains of experience belonging to the spiritual and physical sides of our nature” as says Sir Arthur Eddington. This essay has for subject, historical and philosophical origins of “arrow of time” as a physical notion. It is a case in which we can clearly see the close interplay between physics and philosophy.</p> 2019-09-30T00:00:00+00:00 ##submission.copyrightStatement##
