Treatment of full-thickness cartilage defects relies on osteochondral bilayer grafts, which mimic the microenvironment and structure of the two affected tissues: articular cartilage and subchondral bone. However, the integrity and stability of the grafts are hampered by the presence of a weak interphase, generated by the layering processes of scaffold manufacturing. We describe here the design and development of a bilayer monolithic osteochondral graft, avoiding delamination of the two distinct layers but preserving the cues for selective generation of cartilage and bone.

- The study aimed to analyze the surface structure and elastic properties of four commercial dental flowable composites (Venus Diamond Flow, Vertise Flow, Filtek Supreme XT Flow, Surefil SDR Flow) along with one adhesive system and a non-flowable composite as controls.
- Researchers used scanning electron microscopy and atomic force microscopy to examine surface morphology, while elastic modulus and hardness were measured through instrumented indentation, combining grain analysis and statistical methods for a comprehensive evaluation.
- The findings indicated that Vertise, Filtek XT, and Surefil SDR have stiffness comparable to the non-flowable Venus Diamond, making them more suitable for certain applications, though flowable composites typically lack strength for bulk restorations unless they meet specific criteria, as suggested by the promising results
We measured the size distribution and UV extinction spectra of carbonaceous nanoparticles present in the size range of 1-100 nm in the exhausts of 2004 model gasoline and diesel powered vehicles and compared the results with those obtained in premixed flames. In addition to soot particles, nanoparticles of organic carbon (NOC) were measured in the emissions of these test vehicles in significant number and mass concentrations. The number and mass concentration of NOC was higher than soot in gasoline vehicle emissions.
