Tailoring the Thermoelectric Properties of 3D-Printed n-Type BiSbTe with Incorporated Edge-Oxidized Graphene.

Using three-dimensional (3D) printing technology to fabricate BiTe-based thermoelectric (TE) generators opens a potential way to create shape-conformable devices capable of recovering waste heat from thermal energy sources with diverse surface morphologies. However, pores formed in 3D-printed BiTe-based materials by the removal of the organic ink binder result in unsatisfactory performance compared to the bulk materials, which has limited the widespread application of the ink-based 3D printing process. Furthermore, managing the volatile Se element in the n-type materials poses significant technological challenges compared to the p-type counterparts, resulting in a scarcity of research on 3D printing of n-type BiTe.

Folic acid promotes the myogenic differentiation of C2C12 murine myoblasts through the Akt signaling pathway.

Folic acid is a water-soluble vitamin in the B-complex group, and an exogenous intake is required for health, growth and development. As a precursor to co-factors, folic acid is required for one-carbon donors in the synthesis of DNA bases and other essential biomolecules. A lack of dietary folic acid can lead to folic acid deficiency and can therefore result in several health problems, including macrocytic anemia, elevated plasma homocysteine levels, cardiovascular disease, birth defects, carcinogenesis, muscle weakness and difficulty in walking.

Induction of reactive oxygen species-mediated apoptosis by purified Schisandrae semen essential oil in human leukemia U937 cells through activation of the caspase cascades and nuclear relocation of mitochondrial apoptogenic factors.
