Force to Debond Brackets from High-fusing and Low-fusing Porcelain Systems [PDF]

open access: yes, 2006
The purpose of this study was to test the hypothesis that porcelain surface finishing, ie, low- and high-fusing porcelain, has an effect on the amount of force required to debond orthodontic brackets. A total of 20 high-fusing and 20 low-fusing porcelain

Constructing Mn‐Co‐Fe Ternary Metal Phosphides Nanosheet Arrays as Bifunctional Electrocatalysts for Overall Water Splitting

open access: yesAdvanced Science, EarlyView.
The heterostructure Mn‐Co‐Fe‐P nanoarrays is successfully fabricated on self‐supporting nickel foam by a facile hydrothermal method and phosphating method. In situ growth improves the stability and conductivity of Mn‐Co‐Fe‐P electrocatalysts, and the 3D “sheet–sheet” structure expands the specific surface area of the catalyst and exposes more active ...

Emerging technology and techniques

open access: yesIndian Journal of Dental Research, 2015
A technique of fabricating feldspathic porcelain pressable ingots was proposed. A 5 ml disposable syringe was used to condense the powder slurry. The condensed porcelain was sintered at 900΀C to produce porcelain ingots.

Development of Z‐Scheme Photocatalyst Systems Combining Nonmetal Oxide Materials for Water Splitting under Visible Light Irradiation: (CuGa)0.5ZnS2 as a H2‐Evolving Photocatalyst and TaON as an O2‐Evolving Photocatalyst

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Z‐schematic water splitting under visible light irradiation using TaON as an O2‐evolving photocatalyst, (CuGa)0.5ZnS2 as a H2‐evolving photocatalyst, and reduced graphene oxide as an electron mediator is achieved. This combination of a metal oxynitride and a metal sulfide photocatalysts is new for a Z‐scheme system for water splitting under visible ...
