In this article, we investigated the properties of thermoplastic starch (TPS) with pineapple leaf fiber (PALF)/poly(lactic acid) (PLA) composite compared to both TPS with a PALF composite and TPS/PLA blend. The composite is prepared by a single-screw extruder. It appears that the TPS with PALF/PLA composite gives bett…

Highly efficient and stable blue light emission is observed in novel copolymers that are produced from specially designed building blocks. A PEDOT:PSS-induced chemical degradation of the polymer light-emitting diodes (PLEDs) is identified at the interface, and it is found to be accompanied by a shift in the emission c…

Using a one‐step hydrothermal method and at different stirring speeds ( V s ), we have synthesized different types of CoFe 2 O 4 ‐based magnetic nanocrystalline samples. With increasing V s , the sample changes from a nanocomposite of CoFe 2 O 4 / Co 0.7 Fe 0.3 ( CFO / CF ) to single‐phase CoFe 2 O 4 ( CFO ). The maxi…

In this work, composite samples were prepared using Borassus fibers and a high-density polyethylene matrix. Alternatively, a chemically modified matrix (maleic anhydride grafted HDPE) was also used to improve fiber-matrix compatibility. The effect of fiber loading on the mechanical properties was investigated. Borassu…

We report a synthesis method to stabilize TiO 2 rutile nanoparticles (around 10 nm) and keep the particle size when reduced down to TiO 1.84 . TiO 2−δ nanoparticles exhibit room-temperature ferromagnetism that becomes stronger for TiO 1.84 . The reduction mechanism to stabilize Magneli phases excludes a relevant influ…
