The influence of multifunctional dendritic oligomers on material properties for vat polymerization

open access: yesProgress in Additive Manufacturing
Abstract Stereolithography is a state-of-the-art 3D-printing technology that has increasing impact in the dental, hearing-aid and bioprinting industries. The mechanical quality of the final product is highly dependent on the composition of the resin, polymerization kinetics and conversion rate achieved during the printing process (Watts in ...

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

open access: yesInterdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Perceived Educational Value of a Self‐Developed 3D‐Printed Pediatric Dentistry Simulator

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Purpose To design and assess a 3D‐printed pediatric dentistry simulator and to evaluate its perceived educational value and realism through student and expert feedback. Methods A maxillary simulator that is mountable on phantom heads was developed and produced by desktop stereolithography with single‐use inserts, enabling proximal caries ...

A Density Functional Theory Study of the Structural Preferences of Type B Heteropentalene Mesomeric Betaines and Their Non‐Aromatic Azacyclooctatetraene Isomers

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
DFT has been used to rationalize the relative stabilities of the Type B heteropentalene mesomeric betaines (HMBs) and their azacyclooctatetraene isomers; the tetraaza and triaza HMBs are generally expected to be thermodynamically more stable than their azacyclooctatetraene isomers, whereas the converse is true for diaza systems.

Advancements in 3D Printing of Self‐Healing Polymer Systems

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review provides an overview of the most common 3D printing technologies and summarizes the numerous methods to produce self‐healing materials. The challenges and strategies used to adapt these methods to 3D printing are then highlighted to provide a framework for future research in 3D printing self‐healing polymer systems.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Studies on explosion limits of butadiene-air mixture [PDF]

open access: yes, 1965
The explosion limits of butadiene-air mixtures were determined by means of the admission method and the reaction products, analyzed by gas-chromatography, were CO, CO_2, H_2O, C_2H_4, HCHO etc.

Vat photo-polymerization 3D printing of gradient scaffolds for osteochondral tissue regeneration

open access: yesActa Biomaterialia
In recent decades, osteochondral (OC) tissue regeneration has been one of the major challenges in regenerative medicine. The absence of blood vessels, lymphatic vessels, and nerves in OC tissue prevents self-repair, while the structural complexity and differences between bone and cartilage layers make conventional surgical treatments largely ...
