Investigation of the Solid Carbon Growth Rate and Morphology in Microwave Plasma Conversion of Methane

open access: yesPlasma Processes and Polymers, Volume 23, Issue 9, September 2026.
The solid carbon growth rate and surface characteristics are assessed during microwave plasma conversion of methane. Increasing pressure from 50 to 100 mbar enhances the growth rate of wall‐deposited carbon. Dense, smooth carbon‐like films are observed at the near position at 50 mbar,whereas loose, fish‐scale‐like carbon black particles are observed at

High‐Value Utilization of Typical Vanadium‐Bearing Solid Wastes: Mineralogy, Pathways, and Perspectives

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

Synergistic Chemodynamic–Photothermal Antibacterial Activity of a Nanozyme Derived From Processed Pyritum

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Pyritum can eliminate blood stasis and promote the healing of muscles and bones, which has been used as a traditional mineral medicine in China for thousands of years. However, the mechanisms of action and processing methods of Pyritum were not illustrated.

Multilayer Architecture of PVD/HVOF Coatings Enables Transition in Wear Mechanism and Enhanced Tribological Performance

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT TiN films deposited by physical vapor deposition (PVD) are widely used as protective films due to their high hardness and wear resistance. However, their application under high‐load conditions is limited by poor load‐bearing capacity and susceptibility to spalling on soft substrates.

The photoswitchable ABAMIs for the future regulation of GWT1 in a spatiotemporal level

open access: yesSmart Molecules, Volume 4, Issue 3, September 2026.
The GWT1‐targeted azobenzene‐aminopyridine derivatives (ABAMIs), sensitive to the light at wavelengths from 365 to 520 nm, are separately developed as photochromic ligands to regulate bioactivity as well as the GWT1 functions. These molecules are smart tools in photopharmacological studies, giving an innovative method for understanding functional GWT1 ...

Biosignature Preservation in Stromatolites From the Carri Laufquen Lakes System, Patagonia: Implications for Martian Palaeolacustrine Environments

open access: yesGeobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT The Carri Laufquen Lakes System is a highly alkaline, basalt‐hosted lacustrine environment in northern Patagonia, Argentina. Diverse morphologies of Late Pleistocene sub‐fossil stromatolites occur along the lakeshores. Using detailed optical and electron microscopy, spectroscopy and organic geochemical analyses, this study shows that ...
