Article Synopsis
- Researchers have developed a new method to create polyester nanocomposites by synthesizing calcium borate nanoparticles while simultaneously polymerizing polyethylene terephthalate (PET), eliminating the need for organic solvents.
- * This innovative approach allows for the incorporation of very low amounts (0.1 wt%) of nanoparticles with strong bonding, leading to improved dielectric properties and breakdown strength in the resulting materials.
- * The PET-based nanocomposites achieve high energy storage capabilities, with a maximum discharged energy density of 15 J/cm³, making it a promising and environmentally friendly alternative to existing dielectric polymers for scalable production.
The aphid is an economically important insect that can induce horned galls, which are valuable for the medicinal and chemical industries. Up to now, more than twenty aphid genomes have been reported. Most of the sequenced genomes are derived from free-living aphids.

Tantalum tungsten bronze(TaxWO3)nanowires were successfully synthesized via hydrothermal method using TaCl5 and Na2WO4 . 2H20 as raw materials. The morphology, crystal structure and optical properties of synthesized products were characterized by means of XRD, TEM, SEM, UV-Vis and Raman technologies.

- The band offsets of non-polar A-plane GaN/AlN and AlN/GaN heterojunctions were measured using X-ray photoemission spectroscopy.
- A significant asymmetry was found between the forward and backward band offsets in these heterojunctions.
- The valence-band offsets were determined to be 1.33 ± 0.16 eV for GaN/AlN and 0.73 ± 0.16 eV for AlN/GaN, with a notable 0.6 eV difference attributed to piezoelectric strain effects in the non-polar layers.
