Potassium Silicate as Low-Temperature Binder in 3D-Printed Porous Structures for CO Separation.

Activated carbon sorbents were directly 3D-printed into highly adaptable monolithic/multi-channel systems by using potassium silicate as a low-temperature binder. By employing emerging 3D-printing technologies, monolithic structured sorbents were printed and fully characterized using N, Ar, and CO-sorption and Hg-intrusion porosimetry. The CO-capture performance and the required temperature for active-site regeneration were evaluated by thermogravimetric analysis-looping experiments.

Tunability of Size and Magnetic Moment of Iron Oxide Nanoparticles Synthesized by Forced Hydrolysis.

To utilize iron oxide nanoparticles in biomedical applications, a sufficient magnetic moment is crucial. Since this magnetic moment is directly proportional to the size of the superparamagnetic nanoparticles, synthesis methods of superparamagnetic iron oxide nanoparticles with tunable size are desirable. However, most existing protocols are plagued by several drawbacks.
