ANN‐Enabled Analysis of Nanoparticle Aggregation and Hall Effects on Ag‐H2O Nanofluid Flow Over a Spinning Disk With Convective Heating and Thermal Radiation

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT The exceptional characteristics of nanofluids have turned out to be a significant development in revolutionizing heat transfer mechanisms in several electronic cooling devices and industrial manufacturing processes. The present study deals with the investigation of the second law of thermodynamics applied to the steady MHD fluid flow above a ...

The Evidence for a Binary origin of the Young Planetary Nebula HB 12 [PDF]

open access: yes, 2006
The young planetary nebulae play an important role in stellar evolution when intermediate- to low-mass stars (0.8 $\sim$ 8 M$_\odot$) evolve from the proto-planetary nebulae phase to the planetary nebulae phase.

Bioenergetic profiles and respiratory control in mitochondrial physiology: Precision analysis of oxidative phosphorylation

open access: yesExperimental Physiology, Volume 111, Issue 1, Page 179-211, 1 January 2026.
Abstract Oxidative phosphorylation (OXPHOS) is fundamental to mitochondrial function. Respirometry with living cells provides limited information compared to precision OXPHOS analysis with mitochondrial preparations, including isolated mitochondria, tissue homogenates, permeabilized tissues, and permeabilized cells.

The Influence of Host Star Spectral Type on Ultra-Hot Jupiter Atmospheres [PDF]

open access: yes, 2019
Ultra-hot Jupiters are the most highly irradiated gas giant planets, with equilibrium temperatures from 2000 to over 4000 K. Ultra-hot Jupiters are amenable to characterization due to their high temperatures, inflated radii, and short periods, but their ...

Status and Role of Manganese in the Environment

open access: yesInternational Journal of Environment, 2014
Manganese is the second most abundant heavy metal, and in frequency list of elements it occupies 12th place. The Earth’s core contains about 1.5% manganese. According to Indian Standards for Drinking water (IS 10500:2012) manganese concentration in

Thermal Radiative Flow and Entropy Generation in MHD Williamson Hybrid Nanofluid (Cu+Ag)/H2O Over a Porous Stretching Sheet With Non‐Fourier Heat Flux and Heat Source

open access: yesAdvances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This study investigates the radiative magnetohydrodynamic (MHD) flow of Williamson and hybrid Williamson nanofluids (Cu–water and Cu + Ag–water) over a porous, linearly stretching sheet with suction and internal heat generation. Although nanofluids have been extensively studied, limited research addresses the combined influence of non‐Fourier heat flux,

Design of a Hilbert Curve Fractal MIMO Slot Antenna With Enhanced Bandwidth and Stable Radiation Patterns for Wi‐Fi 7 and Wi‐Fi 8 Applications Using Genetic Algorithm

open access: yesInternational Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Next‐generation Wi‐Fi 7 (IEEE 802.11be) and Wi‐Fi 8 (IEEE 802.11bn) demand compact multielement antennas offering wide bandwidth, high isolation, and stable radiation within limited device space. Conventional MIMO designs often face strong coupling, narrow bandwidth, or low efficiency, restricting high‐throughput multilink performance.

Pseudo‐Natural Products Inspired by Aspidospermidine‐, Strychnos‐, and Koumine Monoterpene Indole Alkaloids Reveal Pyrimidine Biosynthesis Inhibitors

open access: yesHelvetica Chimica Acta, Volume 108, Issue 12, December 2025.
Chemical evolution of alkaloids inspired the synthesis of a monoterpene alkaloid‐inspired pseudo‐natural product compound collection and revealed a novel de novo pyrimidine biosynthesis inhibitor chemotype. ABSTRACT In pseudo‐natural product (PNP) design, natural product fragments are combined in arrangements not found in nature to afford novel ...
