Aggregation of silica powder in water has been experimentally studied by turbidimetry. Aggregation was carried out in a stirred tank under physicochemical conditions corresponding to attractive interparticle forces. The effects of different primary particle sizes and stirring rates on aggregation dy

## Abstract **Summary:** In this paper, we describe the multiple morphogenesis of poly(ethyleneimine) (PEI)‐directed silicas through the facile tuning of the media in which the PEIs pre‐organize. The silica shapes and structures ranged from nanofiber‐based asters, fans, particles, plates, and/or cu

Following to the recent development of the organic-templated growth of materials, new types of photonic hybrid composite materials have emerged whose structure and function are organized hierarchically. Ordered, periodic mesoscopic materials allow the construction of composites with many types of gu
