The recasting effects on the high gold dental alloy properties [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2015
Noble dental alloys are often reused in dental practice by recasting. The aim of this study was to determine if repeated casting of high gold dental alloys has a detrimental effect on alloy microstructure, type of porosity, structure and ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

Advanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

STUDIES ON 16-CARAT DENTAL GOLD ALLOYS

, 1969
The standard dental gold alloy is a 20-carat alloy, but lower carat alloys are also used. In Japan, 14-carat gold alloy3 are still used often in actual practice but from the point of not only resistance to tarnish and corrosion but also from the point of

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.

A Comparative Electrochemical and Morphological Investigation on the Behavior of NiCr and CoCr Dental Alloys at Various Temperatures

Metals, 2021
The purpose of our study is to compare the behavior of two reprocessed dental alloys (NiCr and CoCr) at different temperatures considering the idea that food and drinks in the oral cavity create various compositions at different pH levels; the novelty is
