This study presents a novel approach utilizing the concentration gradient of thiourea dissociation products to synthesize a CdNCN-CdS composite photocatalyst with an atomic-level heterostructure (NCN-Cd-S). The strong electron affinity of CdNCN and efficient electron transfer at the interface enhance photocatalytic hydrogen evolution, achieving a record-high rate of 14.7 mmol·g⁻¹·h⁻¹ under visible light, surpassing other CdS-based composites.
Neuroblastoma (NB), the most prevalent extracranial solid tumor in children, poses a significant therapeutic challenge due to its metastasis and high heterogeneity. A recent study leveraging single-cell RNA sequencing (scRNA-seq) has uncovered vital molecular mechanisms underlying NB's progression and metastasis, shedding light on potential therapeutic targets. The research analyzed primary tumors and matched metastases from NB patients, revealing a 'starter' subpopulation of tumor cells responsible for initiating metastasis. By applying various analytical approaches, including evolutionary trajectory analysis and cell-state differentiation prediction, the study delineated the transcriptional landscape of NB and identified a signature associated with poor prognosis.
