Unification of cosmology and physical chemistry- An emerging horizon in physics

Chinmoy Bhattacharya

The entire world scientific community is well acquainted with the classical laws of physics, the thermo dynamical laws, the Planck hypothesis, and the relativity theories. Etc... and so on for many years but the main essence of the said theories have not reached to many people, and as a result of that, as on today even, some ‘grey’ areas are still left in the above said theories primarily due to the fact that the physical variables like ‘time’, ‘mass’, ‘acceleration’, ‘gravitation’ etc. had been left-out in their ‘abstract’ forms in the said theories. The principal underlying reason behind the same is the lack of the whereabouts of pictorial or geometrical representations of the above said physical variables. The recently discovered Theory of Quantum Gravity (TQG) has however, revealed the geometrical shapes of most of the principal physical variables of the universe and could become able to explain the many cosmic mysteries of the universe, the geometrical profile of the chemical reactions and the equilibrium constants of the chemical reactions, the black body radiation phenomena, the cosmos ‘graviton cycle’, the cold nuclear fusion phenomena, the dimensionality of the universe , the origin of the existences of the seven number of colors of VIBGYOR and apparent grey look of the universe, the dark energy/dark matter and many others. In this article, first of all, it has been established that none of the above said theories remain to be ‘abstract’ when the TQG is imposed on them and also one can, as if visually encounter the said theories in front of their eyes, and can very clearly understand their limitations too. The main essence of the following theories have been evaluated through TQG concepts and labelled with the relevant pictorial representations: a. The ideal gas equation and the 3 laws of thermodynamics. b. The Stefan – Boltzmann law c. The Planck hypothesis of black body radiation d. The cosmological constant of general theory of relativity of Albert Einstein and the dark energy model of Friedman. e. The concept of ‘zero-energy’ universe f. The Newton’s Laws of Motions. The present level of understanding of the global physical science about the geo physics of our cosmos is promoted to the next higher level at this proposition

A glimpse to thiol-ene and thiol-yne polymerization mechanisms

Isa Degirmenci

Sister polymerization reactions thiol-ene and thiol-yne have been attracting attention due to their unique properties in the polymerization field, such as showing the regular step-growth network nature in the product, low shrinking stress, late gelation point, and click nature. These polymerization techniques have been applied in recent innovative research areas, from dendrimer synthesis to microfluidic devices. Electron-rich monomers are reactive for thiol-ene polymerization, while the effect of thiol structures is limited. In addition to this, the main drawing force for chain transfer reaction is the stability of radical intermediate in thiol-ene polymerization. However, the factors affecting the reaction mechanisms for the thiol-yne polymerization (Figure 1.) have not been extensively elaborated yet. The radical hydrothiolation of alkynes by thiols was examined in the early 1930s, and nowadays, this reaction is defined as a click reaction. The application of this method in polymer synthesis results in a product which a regular step-growth network nature. In this study, similarities and discrepancies between the sister’s polymerization reactions have been figured out utilizing quantum chemical tools. M06-2X DFT functional was used kinetic and thermodynamic analysis as a cost-effective method which was proven by a benchmark study

The role of hydrodynamic interaction in the dynamics of active dimer

Tanwi Debnath and Pulak Kumar Ghosh

Janus particle is nano to micro meter sized entity having two distinct faces, only one of which is chemically or physically active. A class of Janus particle is called active or self-propelled Janus which can move extracting energy from environment by creating concentration or thermal gradient at the vicinity of its active surface. As active Janus particle acts as a motor for its self-propelled motion, we model an active Janus particle carrying a cargo (passive particle) to form an active dimer. To use the dimer in different purposes, such as targeted drag (cargo) delivery in medical science, the detailed knowledge about its dynamics in presence of hydrodynamic interaction is necessary. Therefore we study the 3D dynamics of the active dimer suspended in a shear flow. Using numerical simulations, we determine the diffusivity of such dimer in presence of long-range hydrodynamic interactions for different values of its self-propulsion speed and shear flow. We observe that the effect of hydrodynamic interactions is greatly enhanced under the condition that self-propulsion is strong enough to contrast the shear flow. We also numerically investigate the escape kinetics of the active dimer from a meta-stable state. Our simulation results show that the synchronization between barrier crossing events and the rotational relaxation process can enhance the escape rate to a large extent. Moreover, the hydrodynamic interaction conspicuously enhances the escape rate of the Janus-cargo dimer.

An energy and eco/budget friendly (solar powered ) air conditioning/refrigeration system

Nkan Enobong G B

Aim: Producing a Revolutionary Air Condition/Refrigeration System that is Energy and Eco/Budget friendly Method: - Place the pedestal/Floor Fan at a convenient position where it can Oscillate air round freely, clip the Copper Pipes (Ice Block making kits), around the Fan surface, attach and clip the transparent rubber Pipes at the edges of the Copper Pipes, connect the transparent Rubber pipes at the edges of the Copper Pipes, connect the transparent Pipes to the Digital Fountain Pump, one of the Pipes should be connected to the output of the Fountain Pump, the Fountain Pump should be dipped into the water in the fish bowl, the fish bowl is filled with Distilled water (or half filled with Distilled water), it is placed inside the empty Aquarium Glass, the second Transparent pipe, that is coming from the Copper pipes (Ice blocking making kits) is Dipped into the water in the fish bowl, that water is containing the Digital Fountain Pump, the Pump sucks water from the bowl, through the inlet/input opening then sends it out through the outlet source, the water moves through the outlet source, circulates round the Copper Pipes (Ice Blocks making kits), after passing through the Transparent rubber Pipe, the moment the Digital Fountain Pump is turned-on, the circulation starts.
