Summary: The study focuses on the effects of nonlinear thermal radiation and activation energy in axisymmetric rotational stagnation point flow of a hybrid fluid. It was found that the concentration of nanoparticles decreases with activation energy and increasing solid volume fraction of SWCNT and MWCNT. Additionally, increasing the rotation parameter leads to an increase in axial velocity and a decrease in secondary velocity.

Summary: This analysis focuses on the unsteady Darcy-Forchheimer flow and heat transfer of nanomaterial on a stretching sheet, taking into account nonlinear mixed convection, Brownian motion, thermophoresis diffusion, magnetic field, and viscous dissipation. The dimensionless PDEs are solved using a finite difference scheme, and various parameters such as entropy generation, skin friction, mass transfer rate, and heat transfer rate are discussed. Velocity and temperature of the fluid are shown to be affected by buoyancy, Forchheimer number, time, Eckert number, and nonlinear convection parameter. High values of Schmidt number lead to concentration decay but intensify with thermophoretic diffusion and time. Entropy production rate is influenced by Prandtl and Eckert numbers, as well as temperature ratio and volume ratio parameters.

Summary: Physiological systems and biological applications in the past 15 years heavily rely on microscale and nanoscale fluxes. Microchannels have been used for diagnostic assays, cell adhesion and molecular transport studies, and mimicking circulatory system flow. MHD boundary flow has wide applications in engineering and technology, including power generation, polymer industry, flow meters, pumps, and filament spinning. This investigation focuses on the Magnetohydrodynamic (MHD) flow of Prandtl nanofluid, involving mixed convection, energy activation, microorganism, and chemical reaction. The study presents numerical outcomes and graphs on velocity profile, temperature, mass concentration, and microorganism density, considering various parameters like Prandtl fluid parameter, elastic fluid parameter, magnetic field, mixed convection parameter, activation energy, chemical reaction, Brownian motion, thermophoretic force, Prandtl number, and Schmidt number. The results show that the Prandtl fluid parameter and elastic fluid parameter enhance the velocity profile, while the Prandtl fluid parameter reduces the thermal rate with increasing concentration profile. Activation energy exhibits the opposite trend. The obtained numerical outcomes are compared with existing statistics and show good agreement in limiting cases.

Summary: The serious threat of climate change has prompted GCC countries to aggressively seek clean energy sources. Recently, these countries have announced carbon emission targets, with some aiming for net-zero emissions by 2050 or 2060. Governments and energy companies around the world are betting on hydrogen to lower emissions. However, there are obstacles to the adoption of a green hydrogen economy in Gulf countries, including high production costs, infrastructure and transportation issues, regulation, and demand. This study analyzes the obstacles and future prospects of hydrogen economy in the GCC region using SWOT analysis, concluding that while GCC countries have the potential to lead in hydrogen, they need to take risks to compete globally, and the growth of the hydrogen economy depends on external factors beyond their control.

Summary: This study investigates the Marangoni convection flow of Al2O3/water-based nanofluid over a stretching sheet in a porous medium with thermophoretic particle deposition (TPD) and Newtonian heating. The velocity of the nanofluid is influenced by the Marangoni number and porosity parameter, while the heat absorption/generation parameter improves thermal dispersion. The thermophoretic parameter affects the concentration and rate of mass transfer, and the heat source and heat sink parameters influence the rate of heat transfer. Nanofluid outperforms viscous fluid in all cases.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
