An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

On the early chemical evolution of the Milky Way

open access: yes, 2006
A few topics concerning the early chemical evolution of the Milky Way are critically discussed. In particular, it is argued that: 1) Observed abundance patterns of extremely metal poor stars (of Pop. II) do not constrain the mass range of the first generation (Pop.

Zinc‐Containing Bioactive Glass Programs Macrophage Polarization through Extracellular Traps Regulation for Enhanced Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Zinc‐containing bioactive glass (ZnBG) promotes diabetic wound healing by regulating macrophage extracellular traps (METs). Specifically, ZnBG reduces oxidative stress and inhibits the PAD4 and NLRP3/caspase‐1/GSDMD signaling pathways, thereby suppressing MET formation.

Chemical Evolution of the Milky Way and Chemical Tagging

open access: yes, 2022
One of the most important unsolved mysteries of astronomy is the formation and evolution of galaxies. The Milky Way is an ideal testbed for testing our understanding of galaxy evolution, as we can directly observe individual stars and their properties, which is generally not possible in external systems.

LDI, A Lipid Droplet Inhibitor, Disrupts Lipid Accumulation and Modulates Hepatic Lipid Profiles in Fatty Liver

open access: yesAdvanced Materials, EarlyView.
The lipid droplet inhibitor (LDI), templated with large‐pore mesoporous silica and functionalized with PKCα C1A and lipase, targets lipid degradation in fatty liver. The LDI maintains stable association with lipid droplets, thereby suppressing their formation and expansion.

Galaxias Enanas del Grupo Local

open access: yesMomento, 2009
The satellite galaxies of the Milky Way are very important both for the studies of the formation and evolution of galaxies and for the research on the dark matter problem. In the present review paper some structural properties of the Local Group, as well

The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating
