Interpretable Active Learning Identifies Iron‐Doped Carbon Dots With High Photothermal Conversion Efficiency for Antitumor Synergistic Therapy

Aggregate, EarlyView.
On the basis of active learning strategy, we propose an equivalent value—SHapley Additive exPlanations equivalent value—to optimize carbon dots’ photothermal conversion efficiency. Within four iterations, iron‐doped carbon dots are synthesized with the efficiency exceeding 78.7%.

A Hypoxia‐Triggered Bioreduction of Hydrophilic Type I Photosensitizer for Switchable In Vivo Photoacoustic Imaging and High‐Specificity Cancer Phototherapy

Angewandte Chemie, EarlyView.
A hydrophilic type I phototherapeutic agent (NanoPcN8O) was developed which selectively responded to hypoxic tumor microenvironments and switched on type I photodynamic and photothermal effects as well as a photoacoustic signal for activatable photoacoustic imaging and tumor phototherapy.

Synthesis and Antimicrobial Activity of 4-S-Methyl-1,3,4-Oxadiazole Derivatives of Some Natural Amino Acids Bearing Secondary Quaternary Ammonium Salt Moieties

Orbital: The Electronic Journal of Chemistry, 2018
Secondary quaternary ammonium salts (QAS) derived from three natural amino acids (L-Leucine, L-Phenylalanine and L-Methionine) bearing 1,3,4-oxadiazole and acetic acid moieties have been synthesized and characterized by IR, 1H and 13C NMR.

CO2 capture with hydrophobic halogen‐free natural deep eutectic solvents: Perturbed‐Chain Statistical Associating Fluid Theory modeling and molecular insights

AIChE Journal, EarlyView.
Abstract This work systematically investigates CO2 capture with hydrophobic halogen‐free natural deep eutectic solvents (NADES) as absorbents from both thermodynamic and molecular perspectives. A series of NADES consisting of decanoic acid, menthol, thymol, and lidocaine as hydrogen bond acceptors/donors (HBAs/HBDs) were prepared, and the CO2 ...

Taxonomy of Chemical Bondings: Opportunities and Challenges

Angewandte Chemie, EarlyView.
The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.
