Graphene Reinforced Polyether Ether Ketone Nanocomposites for Bone Repair Applications [PDF]

, 2020
To improve the performance of polyether ether ketone matrix (PEEK) in hard tissue repair and replacement applications, we fabricated graphene (G) reinforced PEEK with graded G concentrations (0.1%-5%) through injection molding. The mechanical properties,

Comparative Study of Marginal Gap Among Zirconium Dioxide, Poly Ethyl Ethyl Ketone and Porcelain Fused to Metal Implant Supported Crowns [PDF]

, 2019
Objective: Lifetime and clinical success of implant-supported crown are critically affected by the marginal gap. Marginal misfit maylead to microleakage, cement dissolution accumulation of bacteria, food, and oral debris, potentially causing gingival ...

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Computation‐Less, Bias‐Free, and Ultra‐Broadband Photodetector for On‐Chip Edge Extraction

Advanced Materials, EarlyView.
A computation‐less, bias‐free, and ultra‐broadband photodetector directly converts local optical‐intensity gradients into signed photocurrents through a position‐dependent bi‐directional photoresponse. This intrinsic physical sensing mechanism enables single‐pixel edge extraction from the near‐infrared to the long‐wave infrared at room temperature ...

Resistant Potato Starch Supplementation Reduces Serum Free Fatty Acid Levels and Influences Bile Acid Metabolism

Metabolites
Background: Resistant starches, such as high-amylose maize starch and resistant potato starch (RPS), have prebiotic effects that are linked to improved metabolism at >15 g/day, but the effects at lower doses have not been reported.

Nanotribological Properties of Poly(ether ketone ketone) (PEKK) and Sulfonated Poly(ether ketone ketone) (S-PEKK) Thin Films

, 2002
An atomic force microscope (AFM) was used to determine the nanotribological properties of poly(ether ketone ketone) (PEKK) and sulfonated poly(ether ketone ketone) (S-PEKK) thin films, by sliding the AFM tip on the polymer surfaces and stepwise ...

Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis

Advanced Materials, EarlyView.
Genetically encoded enzyme building blocks self‐assemble into monodisperse, carrier‐free protein beads via a droplet‐based formulation strategy. These programmable catalytic particles enable modular continuous‐flow biocatalysis, from single‐enzyme reactions to multi‐enzyme cascades and bead–bead coupled reactor systems.
