Online investigation of lignin depolymerization via reactor-integrated electrospray ionization high-resolution mass spectrometry

Applications in Energy and Combustion Science, 2022
Depolymerization of lignin can yield phenolic monomeric platform molecules, but depolymerization and repolymerization are proposed as concurrent processes, which greatly limit the yield of monomeric products.

The E3 Ligase NEDD4L Prevents Colorectal Cancer Liver Metastasis via Degradation of PRMT5 to Inhibit the AKT/mTOR Signaling Pathway

Advanced Science, EarlyView.
Neural precursor cell expressed developmentally down‐regulated gene 4‐like (NEDD4L) prevents colorectal cancer liver metastasis through ubiquitination and degradation of protein arginine methyltransferase 5 (PRMT5). PRMT5 degradation attenuates the methylarginine of AKT1.

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

Advanced Science, EarlyView.
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is the key driver of ferroptosis. The authors discovered that PHOSPHO1 lowers the level of PE in retinal pigment epithelial cells thus reducing the formation of lipid peroxides. Lowering PE levels can also prevent the creation of autolysosomes, reduce the production of free iron ...

Electrospray Propulsion Time-of-Flight Secondary Ion Mass Spectrometry Diagnostic [PDF]

arXiv
The design and capability of a novel time-of-flight secondary ion mass spectrometry electrospray propulsion diagnostic is presented to investigate secondary species emission from surface impingement of high-velocity, energetic molecular ion plumes. Designed on the basis of traditional Secondary Ion Mass Spectrometry (SIMS) principles, this diagnostic ...

Mechanism of Cationic Peptide‐Induced Assembly of Gold Nanoparticles: Modulation of Electrostatic Repulsion

Aggregate, EarlyView.
Cationic peptides aggregate citrate‐capped gold nanoparticles (AuNPs), producing a colorimetric change. The figure highlights the interplay between the intermolecular attractive and repulsive forces governing the colloidal stability of the nanoparticles.

Construction of Active Sites‐Accessible Au8 Clusters for Intensive Tumor Pyroptosis

Aggregate, EarlyView.
Ethynylferrocene (EFc) was utilized to engineer molecular‐like gold nanoclusters (NCs) with accessibly catalytic centers, resulting in NCs exhibiting excellent peroxidase‐like activity and the ability to radiosensitize, leading to the production of intracellular oxidative stress and activation of pyroptosis.

Development of an Automated Workflow for Screening the Assembly and Host–Guest Behavior of Metal‐Organic Cages Towards Accelerated Discovery

Angewandte Chemie, EarlyView.
An automated experimental workflow to accelerate the discovery of metal‐organic cages (MOCs), which is often hindered by slow, manual approaches, has been developed. Automation of the synthesis, characterization, and analysis, is supported by computational modelling to rationalize the experimental outcomes, and development of a host–guest assay ...

Full‐Color Tunable Fluorescent Polysiloxanes Driven by Structure Evolution and Aggregation From Amine–Aldehyde Reaction

Aggregate, EarlyView.
To achieve full‐color nonconventional fluorescence, amino‐terminated polysiloxanes are introduced into the amine–glutaraldehyde reaction. The fluorophore evolution from imines to pyridinium derivatives, along with aggregate state regulation, is precisely controlled by thermal treatment.
