One-Step Hydrothermal Synthesis of Multicolour Graphene Quantum Dots and Study of Their Luminescence Mechanism

open access: yesChemistry
Multicolour graphene quantum dots (GQDs), from blue to orange emitting, were successfully synthesized via a one-step hydrothermal method using potassium hydrogen phthalate and o-phenylenediamine as the raw materials.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Reticular Frameworks for Advanced Polymer Materials

open access: yesAdvanced Materials, EarlyView.
Reticular frameworks (RFs) such as metal–organic frameworks, covalent organic frameworks, and hydrogen‐bonded organic frameworks offer versatile platforms for polymer materials innovation, enabling regulated polymerization, efficient macromolecular purification, and polymer functionalization.

Little strokes fell big oaks: The use of weak magnetic fields and reactive oxygen species to fight cancer

open access: yesRedox Biology
The increase in early-stage cancers, particularly gastrointestinal, breast and kidney cancers, has been linked to lifestyle changes such as consumption of processed foods and physical inactivity, which contribute to obesity and diabetes - major cancer ...

Deciphering the Interactions of Carbon Nanotubes and Super P with Silicon and Graphite Active Materials in Silicon‐Graphite Negative Electrode‐Based Lithium‐Ion Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Although defect‐rich Multi‐walled Carbon Nanotubes (MWCNTs) are generally associated with reduced electronic conductivity, our findings uncover a different role: they act as interfacial mediators in Silicon (Si) negative electrode‐based lithium‐ion batteries. Their defect sites and surface functional groups reinforce particle contact, markedly boosting

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a
