This article explores a modern approach to designing carbon dioxide (СО2) sorbents based on the concept of the potential energy landscape (PEL). The authors analyze the relationship between PEL characteristics and СО2 sorption efficiency. The article demonstrates how manipulating PEL parameters enables the development of optimized materials with desired sorption properties. The article investigates the influence of the depth and distribution of energy minima on the selectivity, capacity, and kinetics of СО2 sorption. Various strategies for modifying the PEL, including surface functionalization and the targeted introduction of defects, to achieve the desired sorption characteristics are highlighted. Examples of different types of sorbents, such as MOFs, zeolites, and activated carbons, designed within the framework of the PEL concept. Potential applications of the developed sorbents in carbon capture and storage technologies, as well as the synthesis of chemically valuable products. This review will be of interest to specialists in materials science and energy who are engaged in the development of new sorption materials.

In this paper we investigate "inertial forces" and "fictitious forces" and the relationship between them as understood from the literature of physics where the majority seem to consider them as two labels for the same thing while some seem to suggest they are not identical. Our view and preference is to distinguish between them where fictitious forces should be considered a subset of inertial forces. We also investigate the issue of the reality of fictitious forces and whether they have authentic existence in the physical world or they are a kind of "delusion". Our view is that what is called "fictitious forces" can be either. In this regard, we identify and propose several physical characterizations and distinctions between the two types (i.e. the "apparently fictitious forces" which are physically real and the "really fictitious forces" which are illusory because they are purely frame-dependent as viewed by a non-inertial observer). This is consistent with our preference that fictitious forces should be considered a subset of inertial forces, i.e. "inertial forces" which are real should not be classified as "fictitious" in the real sense while "inertial forces" which are not real should be classified as "fictitious" in the real sense.

Creep deformation, a time-dependent material response under sustained stress, plays a critical role in the long-term performance and reliability of structural components, particularly at elevated temperatures. This article presents a mathematically rigorous analysis of creep deformation mechanisms and a phenomenological framework to describe its stages and evolution. By coupling microstructural insights with continuum mechanics, we derive and validate constitutive models capturing the interplay of stress, temperature, and material properties. The analysis integrates diffusion kinetics, dislocation dynamics, and grain boundary phenomena into a unified formalism, ensuring precision in predicting creep behavior across a wide spectrum of materials.

For more than 300 years, the formula for the force of gravitational interaction is represented by Newton's Uniform Law of Universal Gravitation. During this period the facts that Newton's law of gravitation gives predictions that do not agree with observations have been revealed. Here we show that Newton's law of gravitation is not the only law of gravitational interaction in the universe. In addition to Newton's law of gravitation, a new law of gravitation is obtained: FCos=(mc^2)√Ʌ. The two laws of gravitation (FN=GmM/r^2, FCos=(mc^2)√Ʌ) revitalize classical gravity and develop Newtonian dynamics towards a complete model of gravity. Newton's law of gravitation together with the new law of gravitation provide a complete and consistent description of the gravitational interaction in the universe. The real law of universal gravitation is presented in a new form. The law of universal gravitation is represented by two equivalent formulas: FU=GmM/r^2+(mc^2)√Ʌ; FU=mR^3/T^2*r^2+(mc^2)√Ʌ. The law of universal gravitation turned out to be much more complicated than Newton claimed.

This is a very simple paper describing some methods to measure the values especially in length dimension to a scale much less than that of the least count of the given instrument. The final aim of this paper is to trigger a thought process toget ideas , if any ,for indirect measurement to get less than Planck’s length.

The dominant force in the Universe is gravity. For over 300 years, the gravitational force was represented by a single simple and mathematically perfect formula - Newton's law of gravity FN = GmM/r^2. However, the boundaries of its applicability are limited to the solar system. The revealed gravitational anomalies in the dynamics of stars show that at large distances, Newton's law is not satisfied and has significant discrepancies with observations. The real law of gravity is more complex than Newton's law. For large distances and large masses, the gravitational force dominates in the Universe, which Newton's law "does not see". A new law of gravity Fcos = (mc^2)√Ʌ was obtained, which shows the cosmological force not taken into account by Newton's law. Two laws of gravity (Newton's law + the law of cosmological force) provide a complete description of the gravitational interaction in the Universe.

In this document, we fully review the theory and applications of the Eshelby Ellipsoidal Elastic Inclusion Problem. We rigorously derive all the equations related to the Eshelby Ellipsoidal Elastic Inclusion Problem and its applications to various Micro-mechanics problems like Ellipsodial Inhomogenity, Cracks, and Dislocations.

In the original 1922 Stern Gerlach experiment the single horizontally propagating incident beam was split into two ‘up’ or ‘down’ diverging beams. An observation not consistent with predictions of the time which were that the path deflection angles in a classical model should be deflected up or down in only an even range of angles. Here it is proposed that net translational forces on a dipole in an inhomogeneous field can correctly model the observed split paths for a classical model. In that the dipoles will initially experience a range of very small path deflections via the up or down net translational forces on them as they enter the apparatus. A deflection force dependent upon the specific angle of the N-S axis of polarity of each incident dipole relative to the applied external N-S field in the apparatus. This separation of the beam into 2 paths, one up and one down is effectively a classical version of the "space quantisation" often referred to in QT. After entering the field, the dipoles will then have been sorted into two up and down paths as well as each path having a range of these very small different angled path deflections from the horizontal incident path. They will then all each experience an additional amount of net translational forces applied equally on all aligned dipoles as they propagate through the 3.2 cm length of the external field. Separating the 2 up and down sets into two distinct paths.
