Zinc perfluoro-fluoroalkyl-phthalocyanine, synthesized in high yield, does not exhibit electron loss, does not aggregate in solution, is photostable and produces (1)O(2) in very high quantum yields. Aerobic photo-oxygenation of an external substrate occurs without catalyst self-oxidation. The encapsulation of a metal center in a refractory organic environment could guide the design of other viable catalysts for oxygenation of substrates either for synthesis or for oxidative destruction of organic or biological molecules, under reaction conditions that include the use of only air and light.

Architects of immunity: How dendritic cells shape CD8 T cell fate in cancer.

Koch Institute at MIT, Cambridge, MA 02139, USA.
Immune responses against cancer are dominated by T cell exhaustion and dysfunction. Recent advances have underscored the critical role of early priming interactions in establishing T cell fates. In this review, we explore the importance of dendritic cell (DC) signals in specifying CD8 T cell fates in cancer, drawing on insights from acute and chronic viral infection models.

Explaining the predictions of machine learning models is of critical importance for integrating predictive modeling in drug discovery projects. We have generated a test system for predicting isoform selectivity of phosphoinositide 3-kinase (PI3K) inhibitors and systematically analyzed correct predictions of selective inhibitors using a new methodology termed MolAnchor, which is based on the "anchors" concept from explainable artificial intelligence. The approach is designed to generate chemically intuitive explanations of compound predictions.

In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; HTATB = 4,4',4″--triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. The three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites and basic nitrogen-rich triazines.

Ultrahigh-voltage potassium-ion batteries (PIBs) with cost competitiveness represent a viable route towards high energy battery systems. Nevertheless, rapid capacity decay with poor Coulombic efficiencies remains intractable, mainly attributed to interfacial instability from aggressive potassium metal anodes and cathodes. Additionally, high reactivity of K metal and flammable electrolytes pose severe safety hazards.
