Engineering Ultra‐Low Fe or Ni Loading in Polymer Derived SiCN(O) Fibre Mats: Exploring the Performance towards Alkaline OER

Advanced Materials Interfaces, EarlyView.
Polymer‐derived SiCN(O) fibre mats enable anchoring of ultra‐low amounts of transition metals for efficient alkaline oxygen evolution. The distinct behaviour of Fe‐ and Ni‐based fibres highlights the importance of metal phase and support interactions in tailoring catalytic behaviour.

Raman Spectroscopic Characterization of Radiation Damage in Zircon: Structural Implications for Thermochronology [PDF]

Materials Research
Zircon is fundamental to geochronology, yet its crystal lattice accumulates radiation damage from α-decay of U and Th, progressively modifying physical properties. Raman spectroscopy provides a non-destructive probe of this damage through peak shifts and

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

Advanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

Seeing the Chemistry of Biomolecular Condensates: In Situ Mapping of Composition and Water Content. [PDF]

Adv Sci (Weinh)
Raman hyperspectral imaging combined with spectral phasor analysis enables a label‐free quantification of proteins, polymers and water density within individual biomolecular condensates. By transforming complex vibrational fingerprints into intuitive compositional maps, the approach reveals the high water content and structural heterogeneity of ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Biofilm‐Binding Phages Enhance Biofilm Eradication by Synergistic Photothermal and Photodynamic Therapy

Advanced Science, EarlyView.
Engineered phage‐based trifunctional nanofibers are developed for synergistic biofilm eradication. Biofilm‐binding phages, armed with AuNPs and TCPP, serve as both warheads and scaffolds, endowing the phototherapy agents with biofilm‐anchoring ability. Upon light irradiation, AuNPs induce photothermal therapy, while TCPP generates 1O2 for photodynamic ...
