Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

open access: yesAdvanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Engineering Pendant Group Chemistry to Control Hydrophilicity and Oxidative Degradation of Thioketal‐Based Biomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.

Water‐Compatible SuFEx‐Active Diazonium Linchpin Platform for Rapid Modular Diversification and On‐DNA Functionalization

open access: yesAdvanced Functional Materials, EarlyView.
Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Marine Invertebrate-Associated Bacteria In Coral Reef Ecosystems As A New Source Of Bioactive Compounds [PDF]

open access: yes, 2004
Coral reefs are the most species-rich environments in the oceans. Reefs cover 0.2% of the ocean’s area and yet they provide home to one-third of marine fishes and to tens of thousands of other species.
