Rotational Control and Selective Isotope Alignment by Ultrashort Pulses [PDF]

open access: yesarXiv, 2006
Strong ultrashort laser pulses give rise to prompt molecular alignment followed by full, half and quarter quantum revivals of the rotational wave packets. In Four Wave Mixing (FWM) experiments, we make use of the long succession of repetitive alignment revivals to demonstrate isotope-selective alignment and time-resolved discrimination between ...

Red Blood Cell Membrane‐Camouflaged Red Phosphorus‐Modified C3N4 for Enhanced Tumoral Photodynamic Therapy

open access: yesAdvanced Materials Interfaces, EarlyView.
Photodynamic therapy (PDT) faces clinical challenges due to poor tumor targeting and systemic toxicity. Herein, a biomimetic C3N4‐RP@RBCm nanoplatform is developed via erythrocyte membrane encapsulation, enabling CD47‐mediated immune evasion and EPR‐driven tumor accumulation.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Understanding Chiral Proton Catalysis Using Cinchonium Derivatives in aza‐Michael Additions

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract This work presents a detailed mechanistic study of a quininium‐catalyzed aza‐Michael reaction, providing essential information for advancing chiral proton catalysis (CPC). The use of cinchona derivatives as chiral proton catalysts demonstrates their potential beyond their conventional roles as base‐promoted and phase‐transfer catalysts ...

Tailoring a Functional Synthetic Microbial Community Alleviates Fusobacterium nucleatum‐infected Colorectal Cancer via Ecological Control

open access: yesAdvanced Science, EarlyView.
The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

Therapeutic Delivery of circDYM by Perillyl Alcohol Nanoemulsion Alleviates LPS‐Induced Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
PANEs are specifically designed to enhance the brain delivery efficiency of circDYM compared to commercialized lipid nanoparticles (LNPs). Intranasal administration of PANE‐circDYM effectively alleviated LPS‐induced depressive‐like behaviors by mitigating neuroinflammation and promoting neuroplasticity.
