The wood-to-charcoal process (carbonization) is crucial in developing new materials at the lab for key technological processes nowadays. Unfortunately, laboratory carbonization methods are relatively costly and produce charcoal on a onegram scale. This work presents a simple-to-build and simple-tooperate homemade kiln that carbonizes Eucalyptus wood chips (yield of 30 � 1 %) and produces charcoal on the 200-gram scale (two orders of magnitude higher). As-made solid particles had the typical structure, composition, and chemical behavior of charcoal obtained from wood with standard carbonization procedures. Research of charcoal-based materials is now probably more accessible.
Using a non-toxic precursor, we created a green chemical synthesis for colloidal spheres with a core@shell structure having a silica core and an iron oxide shell (SiO 2 @Fe x O y ). Our synthesis pathway enabled an iron oxide shell formation with a 9 ± 6 nm thick shell onto colloidal silica spheres (ca. 700 nm).SiO 2 @Fe x O y particles reduced A549 cell viability and induced DNA damage. SiO 2 @Fe x O y particles showed the potential for removing uoride from water.

Wood-to-charcoal
is crucial in developing new materials at the lab-scale for relevant
applications, such as pollutant removal from water. Unfortunately, laboratory carbonization methods
are costly and produce charcoal on the gram-scale. This work presents a
simple-to-build and simple-to-operate home-made kiln that carbonizes Eucalyptus
wood chips (yield of 30 ± 1%) and produces
charcoal on the 200-gram scale. Solid particles had the typical structure,
composition, and chemical behavior of charcoal obtained from wood. We believe
that his carbonization process eases the charcoal synthesis required for the
development of new charcoal-based materials.
