Piperazine‐Functionalized Nanoparticles Enable Oral Insulin Delivery in Obese Mice

Advanced Science, EarlyView.
ABSTRACT Biologics have gained prominence as a rapidly advancing therapeutic modality for a diverse spectrum of medical conditions. Nonetheless, they are predominantly administered parenterally due to poor absorption through the gastrointestinal tract. Additionally, repeated injections of biologics such as insulin cause injection pain, leading to dose ...

Effect of structural parameters of active pre-chamber on ammonia/hydrogen premixed combustion process: A numerical investigation

Case Studies in Thermal Engineering
The development of zero-carbon fuels is of great significance for reducing carbon emissions. Using an ammonia/hydrogen mixture as fuel, the combustion in engine through an active pre-chamber has a good effect on reducing carbon emissions.
