The oxidative dehydrogenation of propane with CO (CO-ODP) is a green industrial process for producing propene. Cerium oxide-supported platinum-based (Pt/CeO) catalysts exhibit remarkable reactivity toward propane and CO due to the unique delicate balance of C-H and C[double bond, length as m-dash]O bond activation. However, the simultaneous activation and cleavage of C-H, C-C, and C-O bonds on Pt/CeO-based catalysts may substantially impede the selective activation of C-H bonds during the CO-ODP process.

Non-canonical DNA structures formed by aberrantly expanded repeat DNA are implicated in promoting repeat instability and the onset of repeat expansion diseases. Small molecules that target these disease-causing repeat DNAs hold promise as therapeutic agents for such diseases. Specifically, 1,3-di(quinolin-2-yl)guanidine (DQG) has been identified to bind to the disease-causing GGCCCC (G2C4) repeat DNA associated with amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD).

In recent decades, annual urban fire incidents, including those involving ancient wooden buildings burned, transportation, and solar panels, have increased, leading to significant loss of human life and property. Addressing this issue without altering the surface morphology or interfering with optical behavior of flammable materials poses a substantial challenge. Herein, we present a transparent, low thickness, ceramifiable nanosystem coating composed of a highly adhesive base (poly(SSS-co-HEMA)), nanoscale layered double hydroxide sheets as ceramic precursors, and supramolecular melamine di-borate as an accelerator.

Hemoglobin, composed of α- and β-chains, is essential for oxygen transport and is key in diagnosing and treating gastrointestinal and blood disorders. It also aids in detecting blood contamination and estimating transfusion volumes. Immunological methods, based on antigen-antibody interactions, are distinguished by their high sensitivity and accuracy.

In DNA double helices, Hoogsteen (HG) base pairing is an alternative mode of Watson-Crick (WC) base pairing. HG bp has a different hydrogen bonding pattern than WC bp. We investigate here the binding energy of homeodomain proteins with a HG-DNA duplex, where DNA adopts a HG bp in its sequence.
