The Utilization of Silica–Lignin Composite as a Green Adsorbent for Cobalt and Lead Metal Ions in Aqueous Phase

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in environmental waste can pollute the environment and disrupt human health if not managed properly. Heavy metal contamination from industrial waste, particularly cobalt (Co) and lead (Pb), poses serious environmental and health risks due to their toxicity, persistence, and bioaccumulative nature.

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Selective Sequestration of Toxic NOx Gases by P‐Doped Graphene: A Density Functional Theory Study

open access: yesAdvanced Physics Research, EarlyView.
P‐doped graphene (P‐grap) is explored as an NOx sensor through DFT simulations. The analysis of its geometry, binding energies, electronic properties, and atom‐in‐molecule characteristics demonstrates that P‐grap is a selective sensor for NOx among a mixture of various gases.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Dr. Hans Kohn and the political takeover of the Berlin Medical Society by the National Socialist regime in 1933

open access: yesThe Anatomical Record, EarlyView.
Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.
