Three different blending procedures were used to create multiwalled carbon nanotube (MWCNT)-modified chloroprene rubber (CR)/natural rubber (NR) blended composites (MWCNT/CR-NR). The effects of the blending process on the morphology of the conductive network and interfacial contacts were researched, as well as the resistance-strain response behavior of the composites and the mechanism of composite sensitivity change under different processes. The results show that MWCNT/CR-NR composites have a wide strain range (ε = 300%) and high dynamic resistance-strain response repeatability. Different blending procedures have different effects on the morphology of the conductive network and the interfacial interactions of the composites. If the blending procedures have wider conductive phase spacing and stronger interfacial contacts, the change in the conductive path and tunneling distance occurs more rapidly, and the material has a higher resistance-strain response sensitivity.

Exergames, which blend physical activity with digital gaming, are increasingly recognized for their potential to boost user engagement in exercise. The user perception of these games plays a critical role in sustaining this engagement. Therefore, understanding and effectively assessing user experience (UX) in exergames is crucial to maximizing their appeal and effectiveness.

Introduction: Liquisolid (LS) technology is particularly advantageous for poorly water-soluble drugs administered in very low doses because of the improved dissolution rate and superior content uniformity. However, there is a lack of research papers describing the application of this concept on an industrial scale. Thus, we present trials conducted to develop tablets containing 0.

Purpose: eHealth might contribute to changes in roles and responsibilities of patients and healthcare professionals (HCPs), including the patient's potential to enhance self-regulation. The aim of this study was to identify important aspects and experiences of self-regulation and factors that may support self-regulation in blended rehabilitation care.
Materials And Methods: Semi-structured interviews were conducted among HCPs and patients regarding perceptions and experiences with self-regulation in relation to a telerehabilitation portal.

Non-viral vectors have gained recognition for their ability to enhance the safety of gene delivery processes. Among these, polyethyleneimine (PEI) stands out as the most widely utilized cationic polymer due to its accessibility. Traditional methods of modifying PEI, such as ligand conjugation, chemical derivatization, and cross-linking, are associated with intricate preparation procedures, limited transfection efficiency, and suboptimal biocompatibility.
