Marginal Strength of Collarless Metal Ceramic Crown

International Journal of Dentistry, 2010
Metal ceramic restorations have been implicated for the discoloration in area of labiogingivalmargin. Attempts to rectify this, by altering the design of metal frameworkswill lead to decrease in fracture strength atmargin.

A Reusable Polymeric Sensor Based on Green‐Synthesized CQDs@ZIF‐8 for the Rapid Detection of Nitro‐Explosive Picric Acid

Advanced Materials Interfaces, EarlyView.
This study presents the rational design and synthesis of a highly luminescent polymeric nanocomposite. Initially, highly fluorescent carbon quantum dots (CQDs) are synthesized via a facile hydrothermal method using citric acid and β‐alanine as precursors, followed by rigorous purification through centrifugation and filtration.

Glenoid fractures of the shoulder

EFORT Open Reviews, 2020
Glenoid fractures of the shoulder are uncommon. Any scapular fracture involving the glenoid should be scrutinized carefully for a surgical treatment option. Classification is helpful in deciding the surgical tactic.Cite this article: EFORT Open Rev 2020;5:620-623.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Covalent Network Formation Rate Controls Depletion‐Induced Supramolecular Assembly in Hybrid Double Network Hydrogels

Angewandte Chemie, EarlyView.
Tuning the rate of covalent network formation in hybrid double network hydrogels regulates whether supramolecular filaments retain their low‐nm structures or depletion‐induced supramolecular assembly takes place forming bundles. This kinetic handle programs the mesoscale architecture and toughness of the hydrogels, establishing a link between ...

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening

Advanced Science, EarlyView.
This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...

Circularly Polarized Luminescent and Melt‐Processable Copper(I)‐Organic Glasses Based on 2,2′‐Bis(diphenylphosphino)‐1,1′‐binaphthyl

Angewandte Chemie, EarlyView.
Homochiral Cu(I) cyanide complexes based on 2,2’‐bis(diphenylphosphino)‐1,1’‐binaphthyl (BINAP) form melt‐quenched and desolvation‐derived metal–organic glasses that exhibit circularly polarized thermally activated delayed fluorescence (TADF) at room temperature, enabling processable chiroptical materials.
