Layer‐Specific Dermal and Subcutaneous Delivery via Modular LNP–Hydrogel‐Integrated Threaded Microneedles

open access: yesAdvanced Science, EarlyView.
Guided by spatial transcriptomics and clinical validation, a threaded microneedle platform enables precise layer‐specific delivery across the dermis and subcutaneous tissue. By addressing distinct pathogenic remodeling in different skin layers, this strategy coordinates compartment‐specific intervention, restores tissue architecture, and offers a ...

Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

open access: yesAdvanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

open access: yesAdvanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Stainless Steels

open access: yes, 2011
Abstract Steels that resist corrosive attack from normal atmospheric exposure and contain a minimum of 10.5% Cr and 50% Fe are generally classified as stainless steels. Their special qualities lie in a chromium-rich oxide surface film that quickly regrows when damaged.

An overview of the recurrent failures of duplex stainless steels

Engineering Failure Analysis, 2019
The favourable combination of mechanical and corrosion properties of ferritic-austenitic duplex stainless steels (DSSs) makes this class of materials widely employed in many industries (e.g. petrochemical, nuclear, pulp and paper). Despite their wide and
