An investigation of aluminosilicate zeolite L (structure code LTL) nanocrystals converted from rice husk ash in template‐free system is reported. Crystallization evolution of the zeolite L was monitored and followed by X‐ray diffraction, high‐resolution transmission electron microscopy, scanning electron microscopy, atomic absorption spectroscopy, and infrared spectroscopy techniques. It was found that fully crystalline zeolite L (Si/Al = 3.0) with square tablet morphology was nucleated at 4 h, and the crystals with a mean particle size of 210 nm was completely transformed from amorphous silica after 24 h of hydrothermal treatment.

This work illustrated the preparation of highly dispersive carbonized sawdust by surface functionalization through a facile mild hydrothermal treatment with an aqueous mixture of reactants, potassium persulfate and potassium hydroxide (KPS:KOH), at 160 °C. The dispersion, morphological and purity analyses play an important role in the determination of

The solar drying experiment of seaweed using Green V-Roof Hybrid Solar Drier (GVRHSD) was conducted in Semporna, Sabah under the metrological condition in Malaysia. Drying of sample seaweed in GVRHSD reduced the moisture content from about 93.4% to 8.2% in 4 days at average solar radiation of about 600W/m2 and mass
