Introduction And Aims: Marginal sealing by enamel bonding is important to enhance the durability of the restoration and prevent secondary caries after operative procedure. This study aimed to evaluate the enamel acid resistance and bond strength of an experimental calcium-containing adhesive system.
Methods: All materials were provided by Kuraray Noritake Dental, Inc.

3D printing, as a layer-by-layer manufacturing technique, enables the customization of tissue engineering scaffolds. Surface modification of biomaterials is a beneficial approach to enhance the interaction with living cells and tissues. In this research, a polylactic acid/polyethylene glycol scaffold containing 30 % bredigite nanoparticles (PLA/PEG/B) was fabricated utilizing fused deposition modeling (FDM) 3D printing.

Bacterial cellulose, with mechanical strength, high water absorption, and crystallinity, is used in eco-friendly packaging, wound dressings, and drug delivery systems. Despite its potential, industrial-scale production is limited by inefficiency and high costs, requiring high-yield strains and optimized growth conditions. This study found that indigenous isolates produce superior bacterial cellulose compared to standard strains.

The current study addresses the pressing issue of unsustainable water management, particularly in regions experiencing high water stress. It focuses on examining the viability of polymeric membranes composed of biobased materials, mainly chitosan, for various sustainable water management solutions. The membranes evaluated in the study were blends of PVC with either chitosan-silica or charcoal-silica, designed to enhance their functionality and performance.

Transmission electron microscopy, especially at cryogenic temperature, is largely used for studying biological macromolecular complexes. A main difficulty of TEM imaging of biological samples is the weak amplitude contrasts due to electron diffusion on light elements that compose biological organisms. Achieving high-resolution reconstructions implies therefore the acquisition of a huge number of TEM micrographs followed by a time-consuming image analysis.
