Porous Silica In article number 2206842, Stella Gries, Patrick Huber, and co-workers present a novel approach based on silver nanoparticle-assisted chemical etching (MACE) of macroporous silicon for the synthesis hierarchically porous silicon. The MACE process is mainly guided by metal-catalyzed redox-reaction where nanoparticles drill mesopores into scaffold structure. resulting can be transfo...

Bone tissue engineering may provide an alternative to autograft, however scaffold optimisation is required to maximize bone ingrowth. In designing scaffolds, pore architecture is important and there is evidence that cells prefer a degree of non-uniformity. The aim of this study was to compare scaffolds derived from a natural porous marine sponge (Spongia agaricina) with unique architecture to t...

In tissue engineering, a highly porous artificial extracellular matrix or scaffold is required to accommodate mammalian cells and guide their growth and tissue regeneration in three dimensions. However, existing three-dimensional scaffolds for tissue engineering proved less than ideal for actual applications, not only because they lack mechanical strength, but they also do not guarantee interco...

Much attention has been focused on the biomedical applications of magnesium phosphate cement (MPC) as bone substitution material. The use of porous scaffolds with characteristics such as high porosity along with macropores and three-dimensional interconnected pore structures is beneficial for repairing bone defects. MPC has been proven to be degradable and biocompatible, and therefore might be ...

STUDY DESIGN This was a biomechanical push-out testing study using a porcine model. OBJECTIVE The purpose was to evaluate the strength of implant-bone interface of a porous titanium scaffold by comparing it to polyetheretherketone (PEEK) and allograft. SUMMARY OF BACKGROUND DATA Osseointegration is important for achieving maximal stability of spinal fusion implants and it is desirable to ac...

The development of reliable and affordable all-solid-state sodium metal batteries (ASS-SMBs) requires suitable solid-state electrolytes with cost-efficient processing stabilized electrode/electrolyte interfaces. Here, an integrated porous/dense/porous Na5YSi4O12 (NYS) trilayered scaffold is designed fabricated by tape casting using aqueous slurries. In this template-based NYS scaffold, the dens...

Considering the load-bearing physiological requirement of articular cartilage, scaffold for cartilage tissue engineering should exhibit appropriate mechanical responses as natural cartilage undergoing temporary deformation on loading with little structural collapse, and recovering to the original geometry on unloading. A porous elastomeric poly l-lactide-co-ɛ-caprolactone (PLCL) was generated a...
