Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

open access: yesAdvanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.

Self‐Cascade Catalytic Reaction–Assisted Apoptosis/Calcicoptosis/Ferroptosis Induction with Microsphere‐Aggregated Hydrogels in Triple‐Negative Breast Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Hyaluronic acid‐dopamine‐based intra‐crosslinked microsphere including cisplatin (HPC MS) is fabricated by spray‐drying and calcium/iron ions are introduced for interparticle crosslinking. Designed microsphere‐aggregated hydrogel (MAH) system including cisplatin/CaO2/FeSO4 can provide apoptosis/calcicoptosis/ferroptosis‐mediated chemo/cascade ...

The Epidemics of Injecting Drug Use and Blood-Borne Disease: A Public Health Perspective [PDF]

open access: yes, 1997
In this article, the author first examines the mechanism by which blood-borne disease is transmitted through sharing of injection equipment. Thereafter, he presents a public health strategy for reducing multi-person use of contaminated injection ...

Photothermal Hydrogel with Mn3O4 Nanoparticles Alleviates Intervertebral Disc Degeneration by Scavenging ROS and Regulating Extracellular Matrix Metabolism

open access: yesAdvanced Functional Materials, EarlyView.
The MPTT‐nanozyme‐hydrogel system (Mn3O4@ChS‐HA) provides a multifunctional therapeutic strategy for intervertebral disc degeneration (IVDD), effectively targeting oxidative stress and enhancing AF repair by restoring extracellular matrix (ECM) and redox homeostasis.

Ion sputter textured graphite electrode plates [PDF]

open access: yes, 1983
A specially textured surface of pyrolytic graphite exhibits extremely low yields of secondary electrons and reduced numbers of reflected primary electrons after impingement of high energy primary electrons.
