thermodynamicsSmarr formulaIn this work, a new class of slowly rotating black hole solutions in dilaton gravity has been obtained where dilaton field is coupled with nonlinear Maxwell invariant. The background space–time is a stationary axisymmetric geometry. Here, it has been shown that the ...
This study employed the first-principles computational approach to explore how different central metals (Zn, Cu, Ni) affect the redox properties, thermodynamics, and performance of M(II)-porphyrins. Zn(II)-porphyrin exhibits a redox potential 0.62 V lower than Cu(II) and 0.71 V lower than Ni...
We begin by analyzing these black holes’ thermodynamics and then calculating the perturbed metric and thermodynamic quantities by perturbing the action. Our objective is to examine the consistency of the GP relation across various Power-law terms in the field equations, aiming to gain deeper ...
To evaluate the feasibility of onboard hot-water storage for vehicles, its potential for thermal and work storage density per unit mass is calculated, which is one of the most important gauges for energy storage systems. Referring to Fig. 1b, for the hot-water filling process, the commonly ...

The coal-fired power sector is facing unprecedented pressure due to the shift to low-carbon energy sources and the need to prevent climate change. It is imperative to incorporate advanced technologies into conventional coal-fired power plants to enhance
Electronvolt (unit: eV). Electronvolts are a traditional unit of energy, particularly inatomic and nuclear physics. An electronvolt is equal to the energy gained by a single electron whenacceleratedthrough1 voltofelectric potentialdifference. The work done on the charge is given by the ...
Potential energy of a spring The potential energy formula of a spring is $P.E.=\dfrac{1}{2}kx^2$ The maximum velocity ($v_m$) of a block of mass $m$ upon maximum displacement ($x_m$) is $v_m=\sqrt{\dfrac{k}{m}}.x_m$ Mechanical energy and its conservation. According to...
What are the potential threats that you want to protect against? Are there any vulnerable areas or assets that need extra attention? Do you require round-the-clock protection or just during certain hours? So try making a wise decision based on the nature of your business or property. A ...
special attention given to the relaxing radiation. In agreement with the findings ofChapter 5, the radiation relaxation curve is nonexponential, characteristic of anonlinear system. Provided that nonclassical solutions are admitted (Chapter 7), Hamilton–Jacobi–Bellman equations have the potential of ...
