Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

open access: yesAdvanced Functional Materials, EarlyView.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Human Endometrial Extracellular Matrix Hydrogel Facilitated Endometrial Mesenchymal Stem Cells for Endometrial Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Adequate thickness of the uterine lining is crucial for women with thin or damaged endometrium to achieve pregnancies. Endometrial mesenchymal stem cells (eMSC) can facilitate the cyclical repair and regeneration of the human endometrium. In this study, the human endometrium derived extracellular matrix hydrogel supports the growth of eMSC promoting ...

Natural Sweetener Stevioside‐Based Dissolving Microneedles Solubilize Minoxidil for the Treatment of Androgenic Alopecia

open access: yesAdvanced Healthcare Materials, EarlyView.
This study addresses limitations of minoxidil (MXD) in treating androgenetic alopecia by using stevioside (STV) as a solubilizing agent and microneedle (MN) material. STV enhanced MXD's solubility and skin absorption, leading to improved drug delivery and significant hair regrowth in animal models, demonstrating strong potential for AGA treatment ...
