Ribonucleotides Amplify Mitochondrial DNA‐Driven cGAS–STING Activation via FdUMP‐ribonucleotide Hybrid Particles to Potentiate Chemoimmunotherapy

open access: yesAdvanced Science, EarlyView.
This work develops a metabolic sharing strategy that employs cytidine monophosphate (CMP) to competitively reprogram floxuridine (FUDR) pyrimidine metabolism in colorectal tumor cells. Elevated intracellular FdUMP induces nucleotide imbalance, drives mitochondrial DNA release and cGAS‐STING innate immune cascade activation, and potentiates robust ...

Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

open access: yesAdvanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

The SIFT and FALP techniques; applications to ionic and electronic reactions studies and their evolution to the SIFT-MS and FA-MS analytical methods [PDF]

open access: yes, 2014
Flow tube reactors coupled with quantitative mass spectrometry have made, and continue to make, major contributions to gas phase ion–molecule chemistry, to recombination and electron attachment studies and, most recently, to gas phase trace gas analysis.

A Conduction‐Nucleation‐Competition‐Guided 3D Adaptive Gradient Buffer for Dendrite‐Free All‐Solid‐State Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A self‐adaptive gradient SCMN buffer layer is designed based on a conduction‐nucleation competition mechanism. The design dynamically optimizes ion/electron conduction and lithiophilicity, guiding dendrite‐free lithium deposition. Consequently, symmetric cells deliver exceeding 1600h at 1.5 mA cm−2, and the LiCoO2‐based full cells exhibit 98.5 ...

Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures

open access: yesAdvanced Science, EarlyView.
ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

Advances in Breath Analysis-Based Disease Diagnosis Technology and Standardization Requirements

open access: yesZhipu Xuebao
The composition and content of volatile organic compounds (VOCs) in exhaled breath are closely related to change in the human physiological state. Some biosignature molecules generated by human metabolism, including disease marker molecules, are expelled

Isocyanate‐Modified Melatplatin(IV) Enhances Antitumor Efficacy via TCF4/COL6A3‐Mediated Extracellular Matrix Remodeling and cGAS‐STING Pathway Activation in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
A series of melatonin‐conjugated platinum(IV) prodrugs was functionalized with isocyanate chains (compounds 5‒12). MP‐12C (compound 11) was identified as the lead candidate, with optimal potency and safety. MP‐12C exhibited greater efficacy than cisplatin by increasing intracellular uptake, reshaping the extracellular matrix, activating the cGAS‐STING ...
