Metal-Organic Frameworks: Direct Synthesis by Organic Acid-Etching and Reconstruction Disclosure as Oxygen Evolution Electrocatalysts.

Angewandte Chemie
Metal-organic frameworks (MOFs) have emerged as promising oxygen evolution reaction (OER) electrocatalysts. Chemically bonded MOFs on supports are desirable yet lacking in routine synthesis, as they may allow variable structural evolution and the ...

Surface Characteristics and Biocompatibility of Ultrafine-Grain Ti after Sandblasting and Acid Etching for Dental Implants.

ACS Biomaterials Science & Engineering, 2019
This study investigated the surface characteristics and biocompatibility of ultrafine-grain pure titanium (UFG Ti) after sandblasting and acid etching (SLA) treatment to determine an effective method for modification of UFG Ti dental implants. The UFG Ti

Pyruvic acid as an etching agent

Journal of Oral Rehabilitation, 1976
SummaryPhosphoric acid at different concentrations has been extensively used as an etching agent to improve bonding of dental materials to enamel surfaces. Recently attention has been drawn to the possible use of polyfunctional organic acids as conditioning agents.The object of this investigation was to determine the optimal concentration of pyruvic ...

The continuous brushing acid-etch technique

The Journal of Prosthetic Dentistry, 1987
The continuous brushing of an acid-etching agent onto the enamel surface of an extracted tooth resulted in a more debris-free surface. SEM photomicrographs showed dissolution of some of the apatite crystals and a reduction in size of the remaining crystals, thus increasing the potential space between them for retention of unfilled composite.

Acid-etch canine riser occlusal treatment

The Journal of Prosthetic Dentistry, 1981
Abstract A technique has been described where metal canine risers were attached to the lingual surfaces of maxillary canine teeth with acid-etch composite resin. The castings created a canine-protected occlusal scheme. No enamel needed to be removed from the teeth in their preparation for the restorations.

Antibacterial activities and biocompatibilities of Ti-Ag alloys prepared by spark plasma sintering and acid etching.

Materials Science and Engineering C: Materials for Biological Applications, 2018
In this work, Ti-Ag sintered alloys (Ti-Ag) with different Ag contents were prepared by a spark plasma sintering (SPS) technique, which is a new, efficient and convenient method of powder metallurgy.

Acid‐etching of enamel cavity walls

Australian Dental Journal, 1984
Abstract— The acid‐etched patterns produced on enamel cavity walls and the enamel tooth surface were investigated and the implications of these patterns on cavity preparation for composite resin restorations are discussed.The predominant pattern on enamel cavity walls is of obliquely and longitudinally sectioned prisms.

Acid etch bonded cast orthodontic retainers

American Journal of Orthodontics, 1979
We have described a technique which involves the use of a cast orthodontic retaining appliance bonded by the acid etch technique and composite resin for semipermanent retention. The technique provides an alternative form of treatment which offers some unique advantages over previous retentive techniques.

Self-Etching Primers – an Alternative to the Conventional Acid Etch Technique?

Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2001
The aim of the present in vitro study was to evaluate the bonding capacity of three self-etching primers (Clearfil SE Bond [SE], Clearfil Liner Bond 2V [CLB], Novabond [NOVA]) to enamel. Two adhesive systems with a separate phosphoric acid etching procedure (Gluma Comfort Bond [GLU], Kurasper F [KU]) served as controls.

Effect of acid etching on dentin wettability and roughness: Self‐etching primers versus phosphoric acid

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2007
AbstractObjective: To compare the effect of self‐etching primers and phosphoric acid on the wettability and roughness of smear layer‐covered and smear layer‐free dentin. Materials and Method: Three self‐etching primers (Clearfil SE Bond, AdheSE, and Xeno III) and 10% (w/w) phosphoric acid (H3PO4) solution were evaluated.
