Thermo‐Kinetic Design of Magnesiothermic Reduction for Morphology‐Retaining Porous Si@C Anodes

Small, EarlyView.
Balancing Mg‐vapor supply and surface consumption during magnesiothermic reduction suppresses particle aggregation and preserves monodisperse morphology in porous Si@C spheres. The resulting architecture improves transport uniformity and reduces degradation within the electrode, leading to more stable high‐capacity cycling than aggregated counterparts ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Electrostatic Control of Terahertz High‐Harmonic Generation in Turbostratically Stacked Graphene

Small Methods, EarlyView.
This study investigates electrostatic control of terahertz high‐harmonic generation in top‐gated turbostratic multilayer graphene. A quantitative model combining graphene's thermodynamic nonlinear terahertz response with multilayer bias screening reproduces the experimental yields.

Current Advances of Treatments, Therapeutic Targets, Biomarkers, Novel Drugs, and Machine Learning for Hypopharyngeal Squamous Cell Carcinoma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive subtype of head and neck squamous cell carcinoma with insidious onset, early metastasis, and dismal prognosis. Conventional multimodal therapy achieves limited survival benefit, highlighting an urgent need for refined precision strategies.

Brillouin–Raman micro‐mapping of silicone‐hydrogel contact lenses: Revealing chemical and mechanical heterogeneities

Journal of Microscopy, EarlyView.
Abstract Joint Brillouin–Raman micro‐spectroscopy (BRMS) enables simultaneous, non‐destructive characterisation of the mechanical and chemical properties of soft materials at the micrometre scale, combining GHz‐range viscoelastic information from acoustic modes with the vibrational fingerprint of molecular species.
