The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.
Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

Seeded Synthesis of Monodisperse Core–Shell and Hollow Carbon Spheres
Gil-Herrera, LK; Blanco, A; Juárez, BH; López, C
Monodisperse carbon spheres between 500 and 900 nm are hydrothermally synthesized from glucose on polystyrene seeds. Control over temperature, time, glucose concentration, and seed size yields hybrid spheres without aggregation and no additional spheres population. Pyrolysis transforms the hybrid into hollow carbon spheres preserving monodispersity. This approach provides a basis for functional carbon spheres applicable in photonics and energy storage
Figure 1. SEM images of PS490@C hybrid spheres obtained at different HTC temperatures (160–180 °C) and glucose concentration after 8 h of reaction. Size of the main population of spheres ± standard deviation (in µm) and relative standard deviation (RSD) are also included. Scale bar, 1 µm.
