Skin-Inspired and Self-Regulated Hydrophobic Hydrogel for Diabetic Wound Therapy.

Diabetic wounds are refractory and recurrent diseases that necessitate the development of multifunctional dressings. Inspired by the structure and function of the skin, we herein delicately design a novel swollen hydrophobic hydrogel (QL@MAB) composed of hydrophobic methyl acrylate (MA) and (3-acrylamidophenyl)boronic acid (AAPBA) network and co-loaded with antioxidant quercetin (Q) and antibiotic levofloxacin (L) for efficient diabetic wound therapy. The hydrophobic MA segments undergo phase separation to form a dense "epidermis", ensuring prolonged drug diffusion, long-term water retention, and high water content.

Maximizing the Accessibility of Acid Sites Within Zeolite Catalysts for Syngas Conversion.

Mass transport within zeolites is pivotal in determining the accessibility of active sites to reactants and hence the catalytic performance. However, there lacks of quantitative guidance for synthesis of desired zeolites with reduced diffusion limitation. Herein, we take mordenite (MOR) zeolite as a model, which is characterized by 12-membered rings (MR) channels as transport path towards the active sites within the 8MR side pockets for syngas conversion to light olefins.

High-Quality Gasoline Directly from Syngas by Dual Metal Oxide-Zeolite (OX-ZEO) Catalysis.

Despite significant efforts towards the direct conversion of syngas into liquid fuels, the selectivity remains a challenge, particularly with regard to high-quality gasoline with a high octane number and a low content of aromatic compounds. Herein, we show that zeolites with 1D ten-membered-ring (10-MR) channel structures such as SAPO-11 and ZSM-22 in combination with zinc- and manganese-based metal oxides (Zn Mn O ) enable the selective synthesis of gasoline-range hydrocarbons C -C directly from syngas. The gasoline selectivity reached 76.
