A highly sensitive and selective electrochemical chiral sensor was developed based on the competitive supramolecular interaction of carbon nanofibers(CNFs)embedded sulfobutyl ether-b-cyclodextrin(SBEb-CD)with optically active cationic drugs at glassy carbon electrode(GCE).The difference in intermolecular hydrogen bonding/stability constant/enantioselectivity coefficient and Gibbs free energy of anionic host SBE-b-CD with enantiomers of amlodipine(R-/S-AML),clenbuterol(R-/S-CBL)and metoprolol(R-/S-MET)as a guest paved the way for efficient *** proposed sensing platform(CNFs-SBE-b-CD/GCE)could recognize the aforementioned enantiomers based on the discernible difference of peak potential(S/R-AML(△Ep=135 mV),R/S-MET(△Ep=99 mV)and R/S-CBL(△Ep=111 mV).The binding mechanisms and thermodynamic study of the enantiospecific behavior have been investigated using the host-guest chemistry approach inside the nanocavity and results suggest that S-AML,RMET,and R-CBL show stronger stability constants than their *** of the diastereomeric complex was taken as a measure of enantioselectivity and experimental results indicated that anionic SBE-b-CD is a better chiral ligand than neutral *** fabricated sensor could be a useful lowcost electrochemical tool for molecular recognition of a variety of cationic species not only of drugs but also from other sources.

This work presents a comparative study of the influence of various parameters on the analog and RF properties of silicon-nanotube MOSFETs and nanowire-based gate-all-around（GAA） *** important analog and RF performance parameters of SiNT FETs and GAA MOSFETs,namely drain current（/d）,transconductance to drain current ratio（g_m/I_d）,I_（on）/I_（off）,the cut-off frequency（f_T） and the maximum frequency of oscillation（/max） are evaluated with the help of Y- and H-parameters which are obtained from a 3-D device simulator,ATLAS^（TM）.It is found that the silicon-nanotube MOSFETs have far more superior analog and RF characteristics（g_m/I_d,f_T and /max） compared to the nanowire-based gate-all-around GAA *** silicon-nanotube MOSFET shows an improvement of ~2.5 and 3 times in the case of f_T and /max values respectively compared with the nanowire-based gate-all-around（GAA） MOSFET.

Unified Understanding of Cosmological Energy Fields: Exploring Gravitation, Repulsion, and More

引用

Natural Science 2023年第11期15卷 263-284页

作者： pramod Kumar Agrawal Universal Theory Research Centre Jaipur India

First, we develop a unitary process that can explain all four physical activations: electromagnetic wave, electromagnetic force, repulsion, and attraction. Second, it is clarified that cosmological and physical entities relate to different levels of existence in the universe and, hence, cannot be considered under the same paradigm. We know that biological entities use physical substances as executants;analogously, physical entities use cosmological substances as executants. Therefore, we have introduced new terms for the cosmological substances used as executants in physical activities. Third, this study introduces the primary elements of the cosmological world, such as visibility, forcibility, fullness, and hollowness, and defines them according to their attributes. This study explains how different combinations and placements of primary elements create different cosmological fields. These fields are used in all physical activations. Finally, we explain the entity model and how all physical activations occur. This study concludes that all physical activations use primary elements and follow the same universal law. Therefore, this study addresses the untouched subject of the creation of repulsion and attraction (gravitation). Furthermore, it addresses several cosmic mysteries that are yet to be resolved.

Philosophical Approach to Space Fabric and Propagation of Light

引用

Natural Science 2021年第10期13卷 457-468页

作者： pramod Kumar Agrawal Universal Theory Research Centre Jaipur India

First, the paper proposes that a cosmological entity such as a photon and a physical entity such as an electron belong to two different levels of the Universe. The cosmological entities do not have any physical parameters. Thus, several mysteries of quantum physics are still unresolved because both are considered in the same paradigm. This paper further estab-lishes that the spatial space (medium of propagation) is a fabric made of different cosmo-logical substances. It explains how the space fabric plays an important role in creating dif-ferent cosmic phenomena such as gravitation, repulsion, cosmic inflation, and other mys-teries. This spatial space fabric accepts the electromagnetic wave by way of physical time, creating a spacetime continuum. Next, the paper proposes a new vision that explains how an electromagnetic wave transports photons from an emitter to a receiver with a constant velocity by outlining a new paradigm of time and space and precisely treating photons as cosmological substances. This vision explains how the second postulate of Einstein’s special theory of relativity remains valid even if the time dilation due to velocity is not a reality. The correctness of the approach is validated through the results obtained from previous well-known experiments.

Evolution and Structure of Elementary Physical Particles

引用

Natural Science 2022年第8期14卷 328-342页

作者： pramod Kumar Agrawal Universal Theory Research Centre Jawaharlal Nehru Marg Jaipur India

This paper is presented in two parts. The first part provides a glimpse of the long-awaited unified theory, which explains the parallel activation of different levels of the universe: intellectual (humans), psychological (animals), biological (vegetation), physical (matter), and cosmological (energies) levels, whereas in the conventional approach, the physical and cosmological levels are grouped into the same category. This paper explains the evolution and structure of elementary physical particles (EPPs) based on the evolution and structure of elementary biological particles (cells). The second part of the paper explains the structure and ingredients of the PPE, which are responsible for the creation of the following four fields, as suggested by the author: visibility, forcibility (magnetism), the fullness field, and the hollowness field. All these fields comprise different unknown cosmological substances. These cosmological fields are present in all physical entities and are responsible for all kinds of physical activations. Finally, the paper explains the evolution of electromagnetic waves, electromagnetic fields, gravitation, and repulsion (repulsive gravitation). The theory is consistent with all previously conducted experiments and systematically unfolds several mysteries, thereby demonstrating the validity of the proposed theory.
