A fabrication method for hollow melamine-formaldehyde microcapsules from microbubble templates is presented. This method is based on the direct encapsulation of microbubbles, and thus does not require a liquid- or solid-core decomposition process. This study determined the conditions for controlling the surface morphology, shell thickness, and diameter(More)
ABSTRACT It is known that various plants have purification ability for indoor air pollutants. In this paper the purification mechanism of foliage plant was investigated by analyzing bioelectrical potential. It was first shown that the air purification ability of a plant depends on various environmental conditions, especially on light irradiation. It was(More)
This report is concerned on an indoor air purification ability of plant. Bioelectrical potential responses for both d.c. and a.c. electrical signals were analyzed to investigate the purification process for various chemicals such as formaldehyde and VOC (Volatile Organic Compounds). It was first shown that the air purification ability of a plant depends on(More)
