Palm Kernel Shell Activated Carbon as an Inorganic Framework for Shape-Stabilized Phase Change Material.

Ahmad Fariz Nicholas et al.

Nanomaterials (Basel, Switzerland), 8(9) (2018-09-08)

The preparation of activated carbon using palm kernel shells as the precursor (PKSAC) was successfully accomplished after the parametric optimization of the carbonization temperature, carbonization holding time, and the ratio of the activator (H₃PO₄) to the precursor. Optimization at 500

Temperature-Responsive Pyraclostrobin-Loaded Octadecane Submicrocapsules with Lowered Toxicity.

Aiym Tleuova et al.

Nanomaterials (Basel, Switzerland), 10(12) (2020-12-03)

Pyraclostrobin (Pyr) is one of the most effective fungicides. However, it can degrade via photolysis in water, it is toxic to aquatic life and if inhaled, it has a low solubility in water, that leads to difficulties when applying to
