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.

Enhanced Switching Performance in Single‐Crystalline PbTiO3 Ferroelectric Memristors for Replicating Synaptic Plasticity

Advanced Functional Materials, EarlyView.
This study demonstrated single‐crystalline PbTiO3‐based memristors with atomically sharp interfaces, well‐ordered lattices, and minimal lattice mismatch. The devices exhibited an ON/OFF ratio exceeding 105, high stability, and rich resistance‐state modulation.

Microscale Tin–Bismuth Alloy Prepared via Cooling Rate Control as Anode Material for High‐Performance Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
To investigate the mechanisms about the enhanced buffering effect and morphological retention in fully lithiated Sn–Bi alloys, this study introduces a new bulk bimetallic Sn–Bi alloy with fine grains of uniformly distributed Sn and Bi alloys (≈50 nm) via cooling rate control. This design effectively relieves internal energy buildup and suppresses crack

An update on reverse total shoulder arthroplasty: current indications, new designs, same old problems

EFORT Open Reviews, 2021
Reverse total shoulder arthroplasty (RTSA) was originally developed because of unsatisfactory results with anatomic shoulder arthroplasty options for the majority of degenerative shoulder conditions and fractures.

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

Advanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

Advanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Fast field echo resembling a CT using restricted echo-spacing (FRACTURE) sequence for shoulder joint in normal dogs

Frontiers in Veterinary Science
Shoulder disease is a common cause of forelimb lameness in dogs. Determining the precise underlying cause of shoulder lameness can be challenging, especially in veterinary practice. Computerized tomography (CT) is often the preferred imaging modality for
