The Comparative Evaluation of the Translucency of Crowns Fabricated with Three Different All-Ceramic Materials: An in Vitro Study [PDF]

Journal of Clinical and Diagnostic Research, 2015
Introduction: All-ceramic crowns with different core materials of different strength and aesthetics are available in recent years. The aesthetics of the crown depends mainly on the shade and translucency.

Translucency of Dental Porcelains [PDF]

Journal of Dental Research, 1980
The translucency of comparable shades of five dental porcelains was determined. Both direct transmittance and total transmittance were measured at wavelengths of 400 - 700 nm. For 1 mm of porcelain, the values for direct transmittance were low and averaged 0.13 percent, whereas the values for total transmittance averaged 26.8 percent.

Vascularization of Human iPSC‐Derived Kidney Organoids Using Perfusion Culture, Pre‐Vascularized Collagen Scaffolds, and Decellularized Extracellular Matrix

Advanced Healthcare Materials, EarlyView.
An integrated perfusion‐based culture platform combining pre‐vascularized collagen scaffolds, stromal vascular fraction cells, and kidney decellularized extracellular matrix promotes vascularization of human iPSC‐derived kidney organoids. The platform provides evidence of interactions between vascular networks and glomerular‐like structures and enables

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
