Plasmon–Exciton–Driven Modulation of the Electronic and Optical Properties of MoS2 via Cayley Tree Fractal Nanostructures

open access: yesJournal of Raman Spectroscopy, EarlyView.
This work investigates the change in optical and electronic properties of monolayer MoS2 through the coupling of its excitons and a plasmonic fractal structure. The formation of the heterostructure shows significant enhancement on the edge of the fractal pattern relative to off, owing to the enhanced electric field at the edge of the branches.

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Alloy Solutions for Ammonia Cracking: A Review

open access: yesMaterials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

open access: yesMacromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Interaction of restoration processes with properties within copper‐graphene composites during direct consolidation Interaktion von Wiederherstellungsprozessen mit Eigenschaften innerhalb von Kupfer‐Graphen‐Verbundwerkstoffen während der direkten Konsolidierung

open access: yesMaterialwissenschaft und Werkstofftechnik, EarlyView.
By refining grains and additions of strengthening elements, mechanical properties of electro‐conductive copper can be increased. Fine‐grained coper‐graphene composites were directly consolidated from original powders by rotary swaging to achieve rods with enhanced mechanical properties and electric conductivity of up to 96% international annealed ...
