The transition from insulator to electro-responsive has been successfully achieved by earlier studies for some inorganic materials by applying external stimuli that modify their 3D and/or electronic structures. In the case of insulating polymers, this transition is frequently accomplished by mixing them with other electroactive materials, even though a few physical treatments that induce suitable chemical modifications have also been reported. In this work, a smart approach based on the application of an electro-thermal reorientation process followed by a charged gas activation treatment has been developed for transforming insulating 3D printed polymers into electro-responsive materials.

Nucleic acid-based therapies are among the most innovative approaches for osteoporosis management, although their effective delivery to bone tissue remains a challenge. In this work, SFRP1-silencing GampeR loaded-nanoparticles were prepared and functionalized with specific moieties to improve bone targeting and, consequently, therapeutic efficacy.

As the simultaneous activation of N and CO (single-step) demands an increase of the reaction conditions, we have re-visited the industrial two-step Bazarov reaction. upp-HAp has been designed as a stable multifunctional catalyst capable of promoting both CO and NH adsorption for their subsequent C-N bond formation.
