Acid etching or surface treatment of enamel appear to improve retention by selectively eroding certain hydroxyapatite and facilitating penetration of resin tags and a hybrid layer formation which result in long-term bond strength of adhesive systems. Aim of study: Effect of lasing on shear bond strength (SBS) of flowable composite. Effect of total-etch and self-etch adhesives on shear bond strength (SBS) of flowable composite. Evaluate the failure mode of experimental groups. Materials and Methods: Forty bovine incisors were used, enamel surfaces were ground by silicon carbide paper and samples were randomly assigned into two main groups (Gp A: Non lased group, GpB: lased prepared group). Each main group was subdivided randomly according to the adhesive systems that were used which are: total-etch adhesive (Teco, DMG, Hamborg, Germany) and self-etch adhesive (contax, DMG, Hamborg, Germany). Adhesives applied to the prepared enamel surface according to manufacture instruction. Composite rod applied over the bonded area and cured. Samples were stored in distilled water at 370for 24 hours. The evaluation of shear bond strength was employed by the use of universal testing machine.

Many studies have been done on the shear bond strength of brackets adhered to acid-etched enamel and so far, there is no study on shear bond strength of brackets adhere to laser-etched enamel in Iraq. So, this study is an attempt to compare the shear bond strength of brackets adhered to laser-etched enamel with that of brackets adhered to acid-etched enamel. The application of laser irradiation to etch dental enamel for direct bonding of orthodontic appliance has been studied. CO2 (Carbon Dioxide) laser are capable of producing surface irregularities in human enamel which resemble those resulting from etching of enamel with ortho-phosphoric acid. Whether laser conditioning improves the retention of composite resins to the same degree as conventional acid-etching techniques has been the subject of several investigations.

Tobacco Etch Virus

High Quality Content by WIKIPEDIA articles! Tobacco etch virus (TEV) is a plant pathogenic virus of the family Potyviridae.TEV contains a highly site-specific protease, commonly called TEV protease. Biochemists have used this to their advantage, to create a protein purification system by incorporating TEV protease's recognition site into protein purification tags. A gene construct is created containing the protein of interest fused to a TEV protease recognition site, followed by an affinity tag, such as a Polyhistidine-tag. Following affinity chromatography, the purified protein is then treated with TEV protease. TEV protease cleaves at its recognition site, removing the affinity tag. This allows for affinity purification of proteins that are not well-behaved when fused to protein tags.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Ueda Domain was a Japanese domain of the Edo period, located in Shinano Province (modern-day Ueda, Nagano). Shinano Province is an old province of Japan that is now present day Nagano Prefecture. Its abbreviation is Shinsh . Shinano bordered on Echigo, Etch , Hida, Kai, K zuke, Mikawa, Mino, Musashi, Suruga, and T t mi Provinces. The ancient capital was located near modern-day Matsumoto, which became an important city of the province. The World War II era Japanese aircraft carrier Shinano was named after this old province.

Electron Free Plasma : From Being to Becoming

Electronegative plasmas produced by attaching mobile low energy electrons to create heavy negative ions are very attractive for both fundamental research and plasma processing applications. Electronegative gas plasmas are widely used in microelectronics manufacturing for etching and deposition of thin films. For example, plasmas in gases containing Cl2 or SF6 are used for silicon etching, fluorocarbon plasmas are indispensable for silicon dioxide etching, and oxygen plasmas are used for ashing of photoresist and other polymers. Electronegative plasmas produced in argon and sulfur hexafluoride (SF6) are used to etch silicon, silicon nitride, silicon carbide and titanium carbide with high etch rates and without film residues. Highly electronegative discharges, also called ion-ion plasmas are seen as a promising solution for electric propulsion and neutral beam development. Ion-ion plasmas find application in charge-free semiconductor manufacturing, negative ion sources, and the D-layer of the upper atmosphere. .Here based on CUSP type magntic filter, a source of an almost electron free plasma along with all possible mechanism of negative ion production is discussed.

Laser-induced backside wet etching (LIBWE) is a promising technique for direct patterning of trans-parent materials with high quality. LIBWE causes laser etching at the back surface of the transparent sample that is in contact with an absorbing liquid. In this work, the etch process has been experimen-tally investigated to study the etch mechanism and ascertain the dominating processes at the backside etching of the transparent materials fused silica, glasses, quartz, MgF2, CaF2, and sapphire. The influ-ence of process parameters on etch rate and surface quality have been systematically studied. The main characteristics of the etching process are a small etching threshold (~0.33 J/cm², fused silica), small etch rates (1 20 nm/pulse), small roughness of etched surfaces (less than 10 nm rms), an incuba-tion behavior, and a surface micro topography that depend on the etched material and the liquid. With this knowledge, the fabrication of well-defined and high quality features into fused silica by LIBWE is demonstrated, which is potentially applicable for the shaping of microoptical components.

Self adhesive resin cements in fixed prosthdontics

ggf. zzgl. Versand

Bonding to enamel has been successful since Buonocore introduced the acid-etch technique in 1955. Bonding to dentin has been less predictable because of the wet tubular ultra-structure and organic composition of the dentin substrate. The introduction of the total-etch technique and recent developments in the chemistry of dentin adhesives have made resin-based composite restorative materials and cements almost resistant to microleakage, with bond strengths that approach those of enamel bonding. Resin based adhesive luting materials are widely used for the fixation of inlays, onlays, crowns, posts, and veneers. Resin cements are based on the use of an etch and rinse along with the use of a low viscosity resin composite. This multi-step application technique is complex and rather technique sensitive, and consequently may compromise bonding effectiveness. Recently, new resin-based cements have been marketed that combine the use of adhesive and cement in one single application, thus eliminating the need for pre-treatment of both tooth and restoration.

ggf. zzgl. Versand

Tom Dixons Hängeleuchte Etch Web Pendant ist aus digital geätztem, rostfreiem Edelstahl. Für das Finish wird das Metall extrem poliert und lässt es wie ein Juwel glänzen. Das Licht aus dem Inneren der Lampe wirft die Oberflächenstruktur als interessanten Schatten an die Wand. Gleichzeitig reflektiert die verspiegelte Oberfläche das Aussenlicht und produziert überlagernde Glanzreflektionen. Der britische Designer fand für die Hängelampe Inspiration in der Baustatik und in der Natur. Beides im Zusammenhang mit der Wissenschaft und Mathematik ist die Etch Pendelleuchte eine Ode an die Entwürfe des grossen neo-futuristischen Architekten Buckminster Fuller.Wir sehen sie als zentrales Leuchtobjekt im Wohnzimmer oder als grosszügiges Statement über dem Esstisch. Wahlweise in Messing oder rostfreiem Edelstahl.
