Objectives: The flexural strength and elastic modulus of rapidly prototyped denture base materials are affected by numerous factors including reinforcement with nanoparticles (NPs) and post-curing duration (PCD), though the effect of these two factors together has been overlooked. The present study tested the effect of nanodiamonds (NDs) or silicon dioxide nanoparticles (SNPs) with various PCDs on the flexural strength and elastic modulus of rapidly prototyped denture base materials.
Methods: To measure the flexural strength and elastic modulus, bar-shaped specimens (64 × 10 × 3.

Semitransparent perovskite solar cells (ST-PSCs) for tandem applications typically use a buffer layer deposited via atomic layer deposition (ALD) to protect the cell stack from the damage induced by the sputtering of the transparent electrode. Here, we present a simple yet effective solution-processed buffer layer based on metal-oxide nanoparticles to mitigate sputter-induced damage. We exploit this strategy in a monolithic tandem integrating the optimized ST-PSC on a polished front-side/unpolished rear-side -type silicon heterojunction (SHJ) solar cell.

Creating customizable soft medical implants and devices tailored to patient-specific anatomy represents a significant challenge in healthcare, requiring 3D-printable materials with viscoelastic properties similar to those of natural tissue, high adaptability, and biocompatibility. Here, we develop a family of silicone organogel inks for 3D printing of tunable soft biomaterials via direct ink writing (DIW). We have developed a set of ink formulations comprising photo-cross-linkable silicone polymers, silicone oil, and fumed silica nanoparticles to modify the rheological behavior of the inks, optimize their printability, and control the viscoelastic properties of the printed organogel materials.

Toxoplasmosis, an infection caused by the obligate intracellular parasite Toxoplasma gondii, represents a significant global health concern, particularly for immunocompromised individuals. This study aimed to evaluate the therapeutic effects of silicon dioxide nanoparticles (SiO2-NPs) against both acute (T. gondii RH strain) and chronic (T.
