P53 status, and G2/M cell cycle arrest, are determining factors in cell-death induction mediated by ELF-EMF in glioblastoma.

This in vitro study tested ELF-EMF exposure in U87 and U251 glioblastoma cell lines and assessed apoptosis, cell-cycle distribution, cell size, and mRNA expression of cell-cycle genes. The authors report higher apoptosis induction and increased G2/M arrest in U87 compared with U251, alongside increased U87 cell size…

Novel synthesis of MeO (Ni, Cu, La)@Nano-CoO from combination of complexation and impregnation in ultrasonic intervention for low temperature oxidation of toluene under microwave radiation.

This engineering study describes synthesis of nano-metal binary oxide catalysts using complexation and impregnation with ultrasonic intervention for low-temperature catalytic oxidation of toluene under microwave radiation. The La-Co catalyst prepared with ultrasonic intervention is reported to have the best…

Biodegradable shape memory nanocomposites with thermal and magnetic field responsiveness.

This engineering study reports fabrication of a biodegradable PLLA shape-memory nanocomposite incorporating surface-modified Fe3O4 nanoparticles. The composite showed improved tensile/mechanical and shape-memory properties compared with PLLA, and shape recovery could be triggered by an alternating magnetic field.…

A rapid and facile synthesis of nanofibrillar polyaniline using microwave radiation.

This engineering study describes a microwave-assisted method to synthesize polyaniline (PANI) nanofibers. Reported yields under microwave irradiation were similar to conventional synthesis but achieved in minutes rather than hours. Structural and morphological characterization (FTIR, Raman, SEM, TEM) reportedly…
